WATER TREATMENT SYSTEM
OPERATOR’S MANUAL
Rec2-20 Water Management Unit:
The Rec2-20 water management unit should be
installed as a recycler to transport water between
a water treatment system and local storage tank.
The Rec2-20 unit can then be used to circulate and
refresh stored water. An optional Ozone genera-
tor can be added further sanitize and de-odor the
water. The Rec2-20 unit can also maintain wa-
ter levels in the local storage tank, to prevent
overfl ows and draining. Auxiliary parts are also
available for hose and pressure washers. The
Rec2-20 should be installed as a component of a
system that incorporates multiple water treatment
technologies.
To assure the safety of the Rec2-20 unit,
pretreatment of the waste water should be applied to
remove as many solids and oils as possible prior to
entering the Rec2-20.
Consult a Water Maze representative prior to
combining the Rec2-20 with other pre-treating
and post treating equipment.
TCLP Testing:
TCLP is one of the Federal EPA test methods that
are used to characterize waste as either hazardous
or non-hazardous for the purpose of disposal. TCLP
is an acronym for Toxicity Characteristic Leaching
Procedure. A TCLP test may be required prior to
disposal of your solid waste. Consult a Water Maze
representative for details.
Site Preparation:
The installation site surface should be of compacted
materials, such as concrete, asphalt or pavement
and capable of supporting the Rec2-20 treatment
system.

a fl ushing routine that forces fresh water through
plumbing to prime pumps. Flushing routine will
last fi fteen seconds, however, pumps will need to
continue running for approximately one minute
before they complete priming and reach capac-
ity water fl ow. If pumps do not reach a high fl ow
rate within one minute of fl ushing, repeat rountine
by holding down "ON" switch for three seconds,
again.
UTILITY USAGE
Electrical: 230 Volts, 1 PH
Amps: 21.6 amps
OPERATING ENVIRONMENT
The Rec 2-20 is designed to work in a wide variety
of operating conditions. In normal operating environ-
ments, the system should perform as specifi ed. In
extremely hot or cold environments certain precautions
need to be taken.

Cold Weather
DRAIN SYSTEM WHEN
TEMPERATURES DROP
BELOW FREEZING
Protect the Rec 2-20 from damage
that can occur when freezing
water expands. Freezing water
may cause pipes to burst.
Drain all pipes if a prolonged hard
freeze is expected. Make sure
all valves are open so water can
completely drain from the system.
Cold Climate Conditions
In locations where freezing temperatures will be
experienced on a regular basis or where very cold
temperatures will be incurred, the water treatment
system should be drained when the outside ambient
temperature drops below freezing and/or the water
system (Rec 2-20) should be housed in a heated

WATER TREATMENT SYSTEM
OPERATOR’S MANUAL
WARNING: Live electrical
contacts are exposed, so dis-
connect power fi rst and have
work performed by a qualifi ed
electrician.
Remove cover of the pump
pressure control switch to allow
access to the two nuts used to
adjust the pump operating pres-
sure. The pressure switch on Water Maze equipment
is set at the factory and should not have to be adjusted
at start-up, but will need to be verifi ed at start up and
maintained regularly at least monthly.
1. The nut on the larger spring in the pump pressure
switch, adjusts the pump cut in (cut on) and pump
cut out (cut off) pressures simultaneously.
2. The nut atop the smaller spring in the pump pres-
sure switch only controls the cut out range and
is used to narrow or widen the gap between the
pump cut in and cut out pressures.
3. To cycle the pump less frequently, the gap should
be as wide as possible while still allowing the
pump to shut off quickly when all outlets are
closed. Adjust the smaller spring to widen the
gap between pump in and out (on and off). 40-
45 PSI (CLP, Rec2-20) or 30 PSI (EC1-300A) is
desirable. Adjusting the larger spring should not
be necessary.
4. When making pressure switch adjustments, make
sure all pump outlets are off or closed, except for
the one outlet valve used to relieve and build pres-
sure while making pressure switch adjustments.
PRESSURE TANK
OPERATION
WARNING! When the tank has
been in service and a change
to a higher pre-charge pres-
sure is necessary because of a
required change in the pressure
switch setting, failure to follow
instructions below can cause a
rupture or explosion and could
cause serious or fatal personal
injury and/or property damage.
• Do not adjust or add pressure if there has been a
loss of air.
• Do not adjust the pre-charge pressure if there is
visible exterior corrosion.
• Do not adjust the pre-charge pressure if there has
been a reduction of the pump cycle time or the
pre-charge pressure compared to its initial setting.
A reduction in pump cycle time can result from
loss of tank corrosion and any re-pressurization
or additional pressure could result in rupture or
explosion.
• Pressure tank pressure is factory set but will have
to be checked regularly (at least monthly). Use
an air pressure (tire) gauge. Before checking air
pressure on the pressure tank, purge all water out
of the tank by turning the pump on and pumping
all water out of the pressure tank.
1. Our transfer pump water systems use a water
pressure tank and water pump with these two
pressure operation ranges:
Cut in (start pumping): 20 PSI
Cut out (stop pumping): 30 PSI (EC1-300A)
Cut out (stop pumping): 40-45 PSI (CLP, REC2-20)
2. Typical factory set air pressure on bladder-type
residential water pressure tanks are shipped from
the factory with a standard pre-charge of:
18 psig for models WX-101 and WX-102
18 psig for models WX-103 and WX-203
18 psig for models WX-205 and WX-350
3. Set the well tank air pressure to 2 PSI below the
pump pressure switch cut-in pressure. This is
usually 18 PSI.

CENTRIFUGAL PUMP
Your centrifugal pumps have been quality-built and
engineered to give you effi cient, dependable service.
They are equipped with union connectors to make
installation and future service easier.
The advanced design uses a single speed motor which
reduces operation and maintenance to simple, com-
mon-sense procedures.
PUMP OPERATION
(Infeed Transfer and Ozone Pumps)
WARNING
RISK OF ELECTRIC
SHOCK: USE
CAUTION WHEN
HANDLING.
WARNING: Do not touch pumps,
pump motors, water or dis-
charge piping when the pumps
are connected to electrical
power. Do not handle a pump or
pump motor with wet hands or
when standing on a wet or damp
surface or in water. Never touch
a pump or discharge piping
when a unit is operating or fails
to operate. Always disconnect the pump cord
(power) before handling.
1. The shaft seal depends on water for lubrication.
Do not operate the pump unless there is water. Dry
running (pump not pumping water) will cause seal
damage and eventual pump failure.
2. The motor is equipped with an automatic reset
thermal protector. This means if the temperature in
the motor should rise unduly, the switch will cut off
all power before damage can be done to the motor.
When the motor has cooled suffi ciently, the switch
will reset automatically and restart the motor. If the
protector trips repeatedly (cycling on protector)
the pump should be removed and checked for the
cause of the diffi culty. Low voltage, long extension
cords, clogged impeller, very low head or lift, etc.,
could cause cycling. Cycling of the protector will
cause eventual motor burnout.
PUMP MAINTENANCE
WARNING
RISK OF ELECTRIC
SHOCK: USE
CAUTION WHEN
HANDLING.
WARNING: Before attempting to
service, disconnect power from
unit. Do not handle the pump
with wet hands or when stand-
ing on a wet or damp surface or
in water. Failure to follow
precautions can result in per-
sonal injury and /or property
damage.
NOTE: Only qualified electricians or servicemen
should attempt to repair this unit. Improper repair and/
or assembly can cause an electrical shock hazard.
1. Bearings in this unit are pre-lubricated. No ad-
ditional lubrication is necessary.
2. Cleaning - Occasionally clean the transfer pit and
pump if dirt or foreign matter accumulate. Small
stones, gravel, sand, dirt, silt, etc. can clog and dam-
age the pump and pump seal, eventually causing
pump failure.
3. Disassembly of the motor prior to expiration of the
warranty will void the warranty. It may also cause
internal leakage and damage to the unit. If repairs
are required, return the pump to a local service
station.
4. If the motor has been disassembled or the switch
chamber opened after the warranty expiration
date, the O-rings and gaskets must be replaced.
Care must be taken to assure that the seals, the
switch cover and air tube gaskets do not leak.
5. The pump should be checked for proper opera-
tion weekly or monthly by watching the operation
of the pump. If anything has changed since the
pump was new, the pump should be examined,
and repaired if necessary.

WATER TREATMENT SYSTEM
OPERATOR’S MANUAL
OZONE GENERATOR
Ozone…Nature's Purifi cation Agent
Ozone is produced in nature or artifi cially by man. In
the Earth's atmosphere, ozone is formed when oxygen
is exposed to ultraviolet light or an electrical charge as
during thunderstorms. Ozone's primary function in na-
ture is to purify the air we breathe and screen us from
harmful rays of the sun. In a similar fashion, Water Maze
systems use ozone to disinfect water because ozone
has a number of characteristics that make it ideal for
water treatment.
Ozone's Characteristics:
Ozone is well suited for water treatment and its unique
characteristics are described below:
■ Ozone works up to 3,000 times faster than chlorine
to kill bacteria and destroy harmful microorgan-
isms.
■ Ozone is a more powerful oxidizing agent than
chlorine and bromine and has a better ability to
remove water contamination.
■ Ozone will not form harmful by-products, like
THM's (a problem with drinking water) or chlo-
ramines (by-product of chlorine responsible for
odors, skin irritations and burning eyes).
■ Ozone will not alter the water's pH, thereby reduc-
ing pH fl uctuations.
■ Ozone coagulates small particles in water so clar-
ity is dramatically improved.
■ Ozone acts as a deodorizer removing unpleasant
odors from water.
How the Water Maze Ozone System
Works:
Because ozone is unstable, it cannot be packaged and
used at a later date. For this reason, ozone is always
produced where utilized.
Point-of-use-ozone generation is simple. This powerful
disinfectant is produced from ambient air surrounding the
generator using special ultraviolet lamps located inside
the system's cabinet. To generate the ozone, air move-
ment is created through the use of an air compressor or
water venturi. As air passes over these unique lamps,
the oxygen contained in the air is converted. The result-
ing ozone gas is subsequently introduced to the water
in the inlet pipeline, where oxidation and disinfection
immediately take place.

Ultraviolet Light Safety Requirements
The device used in this product is a Class 1 certifi ed
ozone generator product. Operating this product outside
specifi cations or altering its original design may result
in hazardous radiation exposure, and may be consid-
ered an act of modifying or new manufacturing of a laser
product under U.S. regulations contained in 21CFR
Chapter 1, subchapter J.
CAUTION: Avoid exposure to direct or
strongly refl ected germicidal ultraviolet
rays. DO NOT STARE INTO BEAM.

(GFCI).
Instructions for disposing of your UV
Light Tube
1. Do not break a UV Light Tube. Keep all tubes whole
if possible. If a UV Light Tube is accidentally broken,
wear gloves while picking up the pieces, and care-
fully dispose of them in a trash bag. Wipe the area
with a wet wipe, and put the wet wipe in the same
trash bag. Place the trash bag with broken pieces
inside another trash bag. Mark the bag with a sign
labeled, "Broken Mercury Light Bulb".
2. Remove the UV Light Tube from the Ozone Genera-
tor. Place the used tube in the trash bag, and place
that bag inside another trash bag. Seal the openings
and then tape a slip of paper on the outer bag labeled,
"Mercury LIght Bulb."
3. Take the used and /or broken mercury tube to your
nearest recycling bin for mercury light bulbs..or
take this tube to a state-approved recycling center.

MAINTENANCE:
WARNING: Never look at an
unshielded ozone lamp while
operating the unit. This lamp
will cause severe eye and skin
damage. There is a green indi-
cator light which will dim when
the unit is operating properly
and will turn bright green if
there is a malfunction. See
product description for location
of the indicator light.
Lamp:
The light has a 9,000 hour life expectancy.
Testing the Lamp:
To test the ozone lamp use a voltmeter set on ohms.
First, remove the ozone cover and unplug the lamp
plug from the ozone lamp. NOTE: There are two fi la-
ments - an upper and a lower - inside the lamp. Place
one of the voltmeter leads on one of the lamp prongs
and, with the other lead, touch all of the three remain-
ing prongs. If continuity is not achieved on both upper
and lower fi laments, replace the ozone lamp (Part
#6-0534). (See fi gure 2 below.)
WARNING
EYE HAZARD:
NEVER LOOK
AT UNSHIELDED
OZONE LAMP
LAMP TESTING PROCEDURE
Figure 2
Testing the Ballast:
To test the power pack, use a voltmeter set on the cor-
rect voltage (230V). Place one of the voltmeter leads
into the lamp plug where the white wire goes into it
and plug the other voltmeter lead into the lamp plug
where the blue wire goes into it. If no voltage is pres-
ent, replace the ozone ballast (Part # 8.716-590.0) If
the voltage tests out right and the bulb is good, but
the bulb will still not turn on, replace the ballast. The
internal starter in the ballast has gone bad.
Replacing the Lamp:
Lamps are available from your Water Maze Dealer
should it need to be replaced. Simply turn off the
power, remove the screws on the power pack cover
and remove the cover. Disconnect the plug on the
end of the ozone lamp. Now, loosen the lamp holder
locking ring from around the end of the lamp by turn-
ing it counterclockwise and removing it. Remove the
lamp by grabbing the rubber bushing around the end
of the lamp and pulling it straight out. Remove the
rubber bushing from the lamp and install it on your
new lamp making sure the outer edge of the bushing
is fl ush with the outer edge of the silver end cap on
the lamp. Now, slide the lamp back into the reaction
chamber. The lamp holder may now be reinstalled and
tightened. Reinstall the plug onto the lamp and replace
the power pack cover.
CAUTION: Keep the lamp free of fi ngerprints and
dust particles by only handling the metal end caps
on the lamp. You can clean the lamp with rubbing
alcohol and a soft cloth. A dirty lamp will not allow
maximum ozone output.
