STANDARD SAFETY FEATURES
The WATER MAZE uses electricity, gas and water to
operate. These can be fatal if not handled properly. For
this reason, the WATER MAZE has been designed with
safety in mind. The following are standard safety features
you will find on all WATER MAZE equipment.
Interlock System:
The WATER MAZE has an interlock system which must
be proven before the burner will ignite. All of these inter-
locks are proven through the Veri-Flame.
1. Pre-Ignition Interlocks:
a. High/low gas pressure switches
These switches insure that there is enough gas
pressure to operate the burner but not excessive
pressure (see page 20).
NOTE: The low pressure switch is set at 12 water
column inches (wci). The high pressure switch
is set at 60 water column inches (wci).
b. Air Pressure Switch
This switch insures there is at least 12 water
column inches of air pressure. NOTE: The High,
Low Gas and Air Pressure Switches have inter-
nal lights. If there is a failure, the light goes out.
See pages 43 & 45.
c. Gas Solenoid Valve
This valve must be closed during pre-ignition
checks. If open, the system will shut down.
NOTE: The WB-50 has three gas solenoid
valves. The WB-120 has six gas solenoid valves
(see pages 43-45).
d. 3 Point Sensor Control:
The evaporation tank must have a minimum
amount of water to prevent damage to internal
parts due to excessive heat. If the water level is
at the bottom rod on the 3 Point Sensor Control,
ignition of the burner is prevented (see item 3
page 27).
2. Post-Ignition Interlock:
UV Scanner
A UV scanner looks for the ignition of the burner.
Once the WATER MAZE has gone through the inter-
locks and the 15 second purge process, the burner
goes through an ignition sequence. If the burner fails
to ignite, the UV scanner shuts down the burner.
Filter:
A 20 mesh screen on the incoming waste water line
prevents solids from entering and damaging the pump.

WB • 8.913-984.0-N
WARNING: The gas line must be
installed by qualified person-
nel only. It must be checked for
leaks before installing the WATER
MAZE. All gas piping must com-
ply with local and national fuel
gas codes.
Connect the main gas line to the 1"
or 1-1/2" line on the rear panel of the
WATER MAZE. This will be labeled
“Natural Gas Only” or “L.P. Gas Only” depending on the
machine you purchase. Connect the vent line to the 1"
vent pipe on the rear panel of the WATER MAZE (see
figures 1-3).
CAUTION: This vent pipe must be vented to the at-
mosphere.
Electrical:
The WATER MAZE requires 230 volts single phase. Re-
fer to the serial plate for proper voltage and amp require-
ments for your machine. All electrical lines must be tested
with a voltage meter for proper voltage before connect-
ing to the WATER MAZE. NOTE: If 208V single phase
is the only electrical source available, the step down
transformer must be changed to a 208/120V transformer
(#6-60011) or a buck boost transformer must be used
to increase the voltage.
DANGER: All electrical lines must
be installed by qualified person-
nel only. All installations must
be electrically grounded and
conform to all local and national
electrical codes. Water Maze is
ETL listed.
The electrical connection for the
WATER MAZE is located on the
rear panel conduit box using a 1/2" knock-out. Electrical
conduit must be run all the way to the connection point
in accordance with local codes.
Fresh Water:
During initial start up, we recommend using fresh water in
the wastewater tank. Fill to mark indicated on sight tube
and remove garden hose. Connect the garden hose to the
WATER MAZE at the female connector located on the 3
point level controller. Open valve partially so back pres-
sure doesn't fill up sight glass tube.
Wastewater:
Wastewater is drawn directly into the evaporator using
the air pump supplied. A 20 mesh stainless steel filter
protects the pump from debris. The connection between
the above ground waste water tank and the machine is
made by using a 3/4" I.D. supply hose with common
WARNING
GAS LINE MUST
BE INSTALLED BY
QUALIFIED
PERSONNEL ONLY.
Control Rod:
Automatic wastewater control set points on the 3 Point
Level Controller turns the wastewater air pump on and
off to control the water level inside the evaporator. The
controller also shuts burner off if water level gets to low.
Temperature Control:
Dual, manual reset, and high temperature controls
monitor the internal temperature of the evaporator. If the
exhaust or water temperatures become too high (225°F)
the system shuts down. The temperature is usually in
the 180° to 190° range.
Regulator Venting:
A pressure regulator gas vent is provided. The gas vent
needs to be plumbed to the atmosphere. If the gas
regulator fails, the gas is automatically vented out-
side, preventing a gas buildup in the location of the
WATER MAZE. This must be vented to comply with
local and/or national codes.
Demister Box:
The demister box contains screens inside that prevent
large water droplets from going up the stack (screen
hole size is 3/16").
INSTALLATION
Location:
Locate the WATER MAZE evaporator on a level con-
crete surface in a room that is well ventilated. Protect the
machine from damaging environment such as wind, rain
and freezing temperatures. Leveling feet are provided
with all evaporators.
CAUTION: For natural gas, air ventilation should
be located near the ceiling. For liquid propane, air
ventilation should be located near the floor.
Gas:
The WATER MAZE evaporator is available for operation
in natural gas or liquid propane.
CAUTION: There are major differences in the adjust-
ments of the evaporators. Do not try to operate the
machine using the wrong gas.
The one inch (1") gas supply line on the WB-25, and
WB-50 and (one and one half inch (1-1/2") on the
WB-120) must have a minimum of 2 psig and a maxi-
mum of 10 psig and be of adequate size to supply the
necessary volume for proper burner operation. The high/
low gas switches require between 12-60 water column
inches. There must be a main gas shut-off valve (not pro-
vided) in the gas supply line located next to the WATER
MAZE which can be used as an emergency shut off for
repair or maintenance purposes.

connectors supplied by the customer and is located on
the rear panel with the label, “Wastewater Inlet" (see
page 11). NOTE: The WATER MAZE is automatically
controlled by the 3 point level controller and will supply
wastewater as needed after startup.
CAUTION: Foaming detergents will affect the
evaporation process in the WATER MAZE. An
anti-foaming kit has been installed to control foam.
Venting:
Each evaporator must have its own vent stack. A 10"
vent pipe (WB-50) must be installed using the provided
exhaust stack adapter to the machine's exhaust stack
and be vented to the atmosphere. A 12" pipe must
be used for the WB-120 (see figure 4). The top of the
exhaust stack should be sufficiently above the roof to
allow for proper dispersion of the exhaust. It should be
unobstructed and in compliance with all local and federal
codes. Avoid bends if possible.
NOTE: If possible, the stack should be a single piece.
CPVC is the recommended stack material. If it has
seams, the seams must be sealed with a duct sealant
to prevent moisture leaks since the exhaust is 100%
saturated air. All stacking must be installed by qualified
personnel only.
NOTE: Exhaust stacking must be water tight.
A straight stack is always the best. If you must have
bends, use 45° not 90° elbows. No more than two bends
should be used. A vertical discharge design is our ONLY
recommendation for a rain cover. A vertical rain cover is
an over-sized piece of stack material that is concentric
with the stack. The cover extends 6" down over the top
of the stack to allow flexibility in positioning fasteners.
Both rain protection and back pressure reduction are
achieved with this design. It works because rain never
falls straight down; it always falls at an angle. Therefore,
the cover is made long enough so that any rain will hit the
cover’s inside wall. Rain then runs down the inner wall
and out the angular opening at the top of the exhaust
stack (see page 13).
Air:
Connect air to regulator, adjust to 60-100 psi at 10 cfm
.
PRE-STARTUP CHECK LIST
Follow all pre-start procedures before attempting to start
the WATER MAZE.
1.
Level evaporator using leveling feet or anchor ma-
chine to floor. Anchoring to floor is the preferred
method.
2. Verify the voltage, then connect the electrical lines
to the machine. To be done by qualified personnel.
3. Leak test connected gas line.
4. Connect the wastewater line from the storage
tank.
NOTE: the pH of the wastewater should be kept
between 8 - 10 in the storage tank.
5. Attach (black) N/O float inside wastewater tank just
above outlet so fill pump doesn't suck air.
6. Attach a high heat hose (180°-190°F) to the 3/4"
stainless steel elbow located at the back side of
evaporator for the auto purge cycle. NOTE: Do not
send waste back to fill tank.
7. Attach the stack to the exhaust stack flange.
8. Remove the plugs from the brass orifices on the
gas and air line and install the test valves with the
brass hose barb fittings (not included). (See page
18.) Make sure the gas line is shut off.
NOTE: The valves, fittings, and manometers are
included in the WATER MAZE set-up kit, #7-8200,
which must be purchased separately.
9. Connect the high pressure port of the 0 to 50 ma-
nometer to the bottom gas orifice port and open the
gas line.
NOTE: Make sure the manometer is zeroed before
taking readings. Use the zero set screw at the bot-
tom of the manometer. This will give you the static
gas pressure. For measuring the static gas pressure
on the WB-50/120, use the valve at the bottom of
the machine next to the high gas pressure switch
(see page 18). This pressure should be 45 water
column inches (wci). Close the valve and remove
the manometer. You must have between 12 and 60
wci before the high/low gas switches will allow the
burner to ignite.
10. Connect the 0 to 10 manometer to the hose barbs
on the gas line and open the valves with the low
pressure port of the manometer to the top port of
the orifice and the high pressure port to the bottom
port of the orifice. This will give you the pressure dif-
ferential between the high side, before the orifice,
and the low side, after the orifice. This will be used
later to figure the evaporation rate and to balance
the burner. This reading will be taken after start up
when the burner is being used (see page 18).
NOTE: Items 8 through 10 have been set at the
factory but installation conditions change so adjust-
ments need to be verified.
11. Open the valve on gas line and wastewater line.
12. Connect purge hose to bottom of combustion tank
and run to a separate holding tank. Do not connect
to feed tank.
13. Connect air.
14. Adjust anti-foam air to 2 psi and UV scanner air to
1/2 psi.

WB • 8.913-984.0-N
OPERATING PROCEDURE
First, collect the waste stream. This can be accomplished
with the use of a catch basin, collection pit, sump or any
other process which collects the waste stream in one
location. The collection method should allow for oil and
solids separation. The waste stream must be stored in
an above ground tank to provide a gravity feed situation
to the waste stream pump of the evaporator. The WATER
MAZE air diaphragm pumps are self priming but we do
recommend a positive feed system (see figure 3).
1. A fresh water source is connected to the evaporator
for the initial fill. The evaporator must have a mini-
mum amount of water before it will operate.
2. With the gas line, gas vent, exhaust vent and elec-
trical connected and main disconnect turned on,
push the reset button F1/RST on the timer. NOTE:
Whenever the power to the evaporator goes out, the
reset button F1/RST on the timer must be pushed.
3. Turn the blower switch to the automatic position. This
will engage the blower which will push the water out
of the sparger tube. This causes the water level to
rise slightly in the liquid level float assembly. If the
low water light is still illuminated, attach a garden
hose to the back of the machine and fill the tank
until the light goes out. Now it is time to turn on the
burner.
4. Turn the burner switch to the on position. The system
now goes through the interlocks, 1) high/low gas
pressure; 2) air pressure; 3) closed gas solenoid,
4) low water, bottom setpoint on the 3 point level
control rod. Now a purge cycle will purge the sparger
tube with air for 15 seconds to insure that there is no
gas in the sparger tube. The burner then attempts
to ignite the soft start pilot flame. If there is not an
ignition, the UV scanner shuts the system down and
the start up sequence must be started over.
5. Once the burner ignites, the waste pump switch
can be turned on to introduce wastewater into the
evaporator. This will add wastewater to the system
through the back of the tank.
NOTE: The heat from the burner goes through the
sparger tube and out a slot in the bottom of the
sparger tube, and finally, into the surrounding water.
There are five stainless steel screens on a WB-50
and ten on the WB-120, that break down the size
of bubbles (from big to small) which increases the
surface area and transfers virtually 100% of their
heat to the water to increase saturation (screen hole
size is 1/16").
Auto Purge:
The unit will automatically purge the waste stream from
the combustion chamber at a set time depending on
your waste stream. This purged waste stream must
be sent to an appropriate discharge holding tank and
not back to the feed or inlet holding tank going to
WATER MAZE.
PRINCIPLES OF OPERATION
The WATER MAZE evaporator is designed to evaporate
wastewater. WATER MAZE uses a unique method of
introducing the wastewater directly into a 2000°F flame.
Using submerged combustion technology, the WATER
MAZE can obtain virtually a 100% heat transfer for a
more efficient and less costly method of evaporation.
In order to understand how this system works and why
it is superior to any other evaporator on the market, it is
important to understand a few aspects of relative humid-
ity, submerged combustion and efficiency ratings of this
type of equipment.
First, relative humidity is called “relative” because the
amount of moisture a given amount of air can hold is
directly related to its temperature. For example, let's say
it's snowing. If you were to take a cubic foot of outside
air at 20° F, with a relative humidity of 100% and bring
this air inside and warm it up to 72°F; the same air would
have the same amount of moisture in it, but would have
a relative humidity of only 15%. The warmer the air is,
the more moisture it can hold. With regard to the WATER
MAZE, this "thirst" or affinity for moisture in hotter air is
especially dramatic at temperatures above 150°F.
Second, it will be of value for you to be familiar with some
basics of water heating and evaporation. All of this type
of equipment will be rated in terms of British thermal
units (BTU's) per hour.
A BTU is the amount of heat necessary to raise one
pound of water one degree Fahrenheit.
Let's say we want to evaporate one pound of water:
In order to get our pound of water from 60°F to 212°F,
we will have to add 152 BTU's to it (212°F minus 60°F).
This is called “sensible” heat.
Once this pound of water reaches 212°F, 970 BTU's must
then be applied to turn it into a pound of steam vapor still
at 212°F. We just want to change it from liquid water to
steam vapor and not raise the temperature at all. This
is called “latent” heat.
Therefore, to get our pound of 60°F water to 212°F
steam took 1122 BTU's.
A gallon of water weighs 8.34 pounds. In order to make
a gallon of water evaporate, we have to subject it to 8.34
lbs. x 1122 BTU's or, 9357 BTU's.

SETTING THE BURNER
The quickest and easiest way to adjust the air and gas
differential to the appropriate settings listed below is to
purchase the WATER MAZE set up kit (#7-8200). Refer
to figure 7 for locations on setting the burner. Shut main
gas valve off. With 7/16" wrench remove brass plugs
from all metering orifices on back side of machine. Install
brass valves included in set up kit into each position
and close. Turn gas main valve back on. To set static
pressure, use 0 - 50 manometer on (D or E). To adjust
setting to desired 45 wci, remove cap on gas regulator
(F) and turn inside adjustment screw clockwise for higher
pressure, counterclockwise for lower pressure. Replace
cap. Start machine by turning the blower switch to the
“auto” position and burner switch to the “on” position.
Once the burner lights, use the 0 - 10 manometer to set
the air differential at (B). Note: lower port is high pres-
sure and upper port is low pressure. With hoses in posi-
tion, open brass valves. Set air differential as per chart
below. Note: needle will shake; pinch both hoses lightly
together to read number. Adjust by opening or closing
main air butterfly and secondary air butterfly (located
on left side of burner, up top). Close brass valves. Set
the gas differential the same way as the air. Note: read
NATURAL GAS:
LIQUID PROPANE GAS:
chart for proper gas used. Attach 0 - 10 manometer at
(C) and set as per chart. The adjustment valve is located
to the right of the burner up top. Remove the brass cap
and adjust with a standard screwdriver. You will have to
set one burner at a time on a WB-120. Once adjusted,
shut off burner and blower. Shut off main gas line. Now
remove the brass valves used with the manometers and
replace plugs into the air and gas orifices. Turn the main
gas back on and follow the procedures for start up. Your
evaporator is now in service.
SOFT START IGNITION
To provide a smooth ignition and meet all gas train
standards, the WB-50 and WB-120 come standard with
the soft start ignition system. Before trial of ignition the
Veri-Flame will make sure the top gas solenoid is closed
(proof of closure). Once closed, the Veri-Flame will try for
a pilot flame. After approximately 8 seconds, the proof
of closure solenoid will close and allow the main gas
solenoid to open slowly.
Soft start settings: The gas metering orifice SBO-A-1
(A) for the soft start needs to be set on 7 wci for the gas
differential. Follow (Setting The Burner) instructions for
setting the soft start gas differential.

FOAMING
The WATER MAZE uses a high volume of air to operate
the burner, which pushes the heat out of the sparger
tube and into the evaporation tank. There, the air goes
through baffle screens to break the air bubbles down
into smaller sizes. This process can cause excessive
foaming from the detergent used in the washing process
if it has any kind of foaming agents. This foam interferes
with the evaporation process of the WATER MAZE and
the foam will go up the stack causing problems with the
venting of the WATER MAZE.
The best solution is not to use detergents or cleaning
compounds that cause foaming. An anti-foam pump is
a standard feature on this machine. WATER BLAZE has
defoamer chemicals available, developed for use in the
evaporator.
CONVERTING NATURAL GAS
TO L.P. GAS
WARNING: Before converting
from natural gas to L.P. gas, be
certain that the evaporator is shut
down, the water has been cooled,
the gas line is shut off and the
power is disconnected.
The WATER MAZE can be ordered
from the factory in natural gas or
L.P. gas. Once they are in the field,
you must order a conversion kit to
change from natural gas to L.P. gas
or from L.P. gas to natural gas.
WB-50/120:
The conversion kit for the WB-50/120, natural gas to
L.P, is # 8.906-072.0.
Remove the SBO-D-7 and replace it with SBO-C-3.
(See items 19 and 21 on pages 42 & 43.) Change the
regulator orifice. Remove the 5/8" orifice and replace
with the 1/2" orifice.
To replace the orifice, disconnect the 3/4" gas line at the
unions above and below the metering orifice. Remove
the section of pipe by unscrewing it from the orifice and
then remove the orifice by unscrewing it from the pipe
above it.
Install the new orifice by applying pipe sealant to the
pipe coming from the gas solenoid valve and screw the
orifice to the pipe. Apply pipe sealant to the section of
pipe that was removed and screw it into the bottom of
the orifice. Reconnect at the unions.
NOTE: Be certain that the orifice is installed right side
up or the system will not work properly. The orifice has
an arrow indicating the flow. If there is not an arrow, look
on the side of the orifice where the plugs are located.
One has green paint around it, the other has red paint.
The plug with green paint goes on the top.
Change the regulator orifice in the gas regulator from
1/2" for natural gas to 3/8" for L.P. gas. Remove the
regulator at the unions. The orifice sits in the tee below
the regulator unions. Use a 1" socket with an extension
to remove the orifice. Put the new 3/8" orifice in. Replace
the regulator.
Replace the “Natural Gas Only” label with the “L.P.
Gas Only” label.

The Veri-Flame is the controller which proves all of the
interlocks. It provides for a purge cycle to insure that
there are no combustibles in the sparger tube before
the trial for ignition (TFI). The length of the purge cycle
is determined by the settings on the Veri-Flame. It is
preset at the factory for 15 seconds.
If you need to check the settings on your Veri-Flame
or if you replace a Veri Flame and it needs to be set,
remove the screws holding the cover on and unplug the
cover from the back. Dipp switches are located on the
reverse side. Set the eight switches as follows: switch 1
ON, switch 2 OFF, switch 3 ON, switch 4 ON, switches
5, 6, 7 and 8 OFF.
If switch 1 is ON, the burner will recycle once after an
air or main flame failure. Otherwise, the system will shut
down.
A pilot light is not used so switch 2 is set to OFF. Switch
3 controls the amount of time the machine has for TFI.
With this switch set to ON, the machine has 10 seconds
for TFI. Switches 4 through 8 control the amount of
purge time before TFI. Switch 4 gives the machine a 15
second purge before TFI.
A Veri-Flame and U.V. scanner tester is available
(#7-8063).
3 POINT SENSOR CONTROL
The 3 point sensor control is part of the safety interlock
system and also controls the wastewater air diaphragm
pump.
The bottom rod is the low water safety position. If the
wastewater level is too low, this rod, working through the
Veri-Flame, will not allow the burner to ignite. When the
wastewater level drops to the position of the middle rod,
there is a demand for water and the wastewater pump
turns on. The air diaphragm pump continues to run until
the top rod is reached by the wastewater. At this point
the pump shuts off. When the level drops to the middle
rod, the wastewater pump restarts again.

8. Loosen the air/gas line unions and remove the
burner from the mounting flange. Clean the nozzle
inside the burner with a small steel brush removing
any build up that is obstructing the mixing of the air
and gas through the nozzle. Replace the burner
mounting gaskets with new gaskets each time the
burner is removed.
9. Refill the WATER MAZE tank with water to the
minimum restart liquid level. Restart the blower and
burner and verify air/gas ratios with manometer for
proper operation of the burner.
Chlorides/Fluorides
Water evaporation tends to concentrate non-volatile
solids in a waste stream. Thus chlorides, fluorides and
related corrosion increase as the volume of the waste
stream decreases. In order to obtain the maximum life
from the WATER MAZE, it is important to monitor the
chloride and fluoride content of the liquid in the evapora-
tion tank, so the waste can be purged prior to damage
by chloride or fluoride corrosion.
Clean Screen:
Shut off the wastewater valve (not included) located near
the “wastewater inlet” on the back end panel. Unscrew
the filter housing and remove the 20 mesh filter. Clean
and replace the screen. Screw the filter housing back
into place and open the wastewater valve (See figure 3).
Clean U.V. Scanner & Ignition Plug:
Once a month, the UV scanner needs to be removed and
cleaned, usually by wiping the scanner off with a cotton
swab and replacing it. Also every month remove the igni-
tion plug and clean it. Check for damage or wear.
Demister Box Screens:
Remove the screens from the demister box and clean
them off. Replace them in the demister box. Make sure
that the door is secure and the gasket is good so that
there are no leaks.
Anti-Foam Maintenance:
CAUTION: Do not attempt to feed chemicals without
consulting your chemical feeder dealer or chemical
supplier.
1. Filling the Chemical Tank
To avoid running out of chemical, follow a regular
schedule of monitoring the chemical supply. Also
inspect and clean the strainer by flushing with a
compatible liquid, as needed.
2. Tubing Inspection
Inspect all tubing regularly and replace it if deteriorat-
ing. Follow the instructions with figure 10 to replace
the pump head tubing.
3. Feeding Adjustment
The feed adjustment is under the front cover. Re-
move the cover and turn the screw clockwise to
increase the feed or counterclockwise to decrease
the feed. Replace the enclosure cap after making
the adjustment. NOTE: Always start with the lowest
feed rate. (See figure 10). Lower feed rate pumps
are available.

Now that the system is adjusted, turn the pump on.
The pump will come on and inject “anti-foam” into the
waste stream when the wastewater pump comes on.
The Full Speed setting can be used to fill the feed
lines more quickly.
Sludge Removal:
Remove the doors on the right side of the WATER MAZE.
At the bottom of the evaporation tank you will find a
1-1/2" ball valve. Connect a hose to the valve and place
the other end into a container. Open the valve and flush
out the sludge. If nothing comes out, you may need to
run a wire into the valve to break loose the sludge that
has collected in the evaporation tank. Once the sludge
has been drained, close the valve.
NOTE: Drain water level below the sparger tube before
removing item E (See figure on page 23).
Sparger Tube Cleaning:
The tool kit, (8.903-719.0), consists of four items. Check
to ensure that the kit is complete (refer to the drawing).
A. Tool handle (2 pc.)
B. Probe/scraper
C. Trough assembly
Remove the panel that covers the flange assembly (this
cover is not shown in this drawing). Use a 3/4" socket to
remove the nuts holding the front of the flange assembly
(E) from the rear flange assembly (D). Also remove the
gasket and check it for damage or wear.
Next, place the trough assembly (C) onto the bottom
two studs of the rear flange (D) and replace the nuts to
hold it securely in place. Assemble the tool by screwing
the tool handle (A) into the probe/scraper (B). Place the
probe/ scraper tool as far back into the sparger tube as
possible. While pulling the scraper forward, scrape out all
of the buildup that has accumulated inside of the sparger
tube (H) and direct it into the slot of the sparger tube.
Continue until the sparger is clean. Clean out the slot (F)
inside the sparger tube. Remove sludge from the bottom
of the tank monthly.
Once this is completed, remove the probe/scraper and
the trough assembly (C). Make sure the gasket is clean
along with the surface area between the front flange (E)
and the rear flange assembly (D). Place the gasket over
the studs on the rear flange assembly and then do the
same with the front flange assembly (E). Use the 1/2"
nuts to secure the flange assembly. Refill the evaporator
tank and check the flange assembly for leaks. Replace
the panel that covers the flange assembly.

To complete setting the timer, first pull the face plate
of the timer out of its holder with your fingers. This will
expose the internal circuit boards. Along the left side
(wall) you will see two (blue) jumpers. Pull upward on
the blue jumper not touching the side wall and move
it forward one position on the pins. This is the lock out
mode for the timer.
Slide the timer back into its holder. Initial programming
of the timer is complete. Once power is supplied to
the timer via the main disconnect on the Water Maze,
the button must be pushed to set the timer in
run mode.
NOTE: Reprogramming can not be preformed with the
blue disable jumper in the forward position. Remember,
if reprogramming is to be done, always place the disable
jumper in the most forward position when done.
NOTE: Original cycle timer has been preset at
factory.
