WCP Automatic Backwash Series Operator's Manual 9
As pressure washers are being operated, used water ows into the Wash Water Catch Pit (1). From there, it moves
to the 3-Stage Collection Pit (2). Heavy debris falls to the bottom of the pit where it is trapped by a weir which is
designed to stop heavy debris while allowing the remaining water to move into the Sump Pit (3). The Sump Pump (4)
draws water from the Sump Pit (3) and brings it through the Water Inlet Flow Control Valve 1. This adjustable valve
is used to regulate the ow of water entering the water clarication tank. A Flow Meter (5) is positioned just ahead of
the water clarication tank. The water enters the water clarication tank through the Inlet Tee (6) and is directed down
to the Diverter Tee (7). From there the water is deected downward by the Solids Deection Cone (8), then to the
Solids Separation Chamber (9). The Solids Separation Chamber (9) allows the velocity of the water to slow so that
any suspended solids settle to the bottom. The water then rises up through the Oil Coalescing Cones (10).
1) The non-emulsied oil molecules in the water adhere to the Oil Coalescing Cones (10). When
enough oil molecules attach to each other, they form oil droplets. The oil droplets are carried along
with the water through the Top Separator Cone (11) and into the Oil Separation Chamber (12),
where the oil droplets oat to the surface. The Oil Skimmer (13) is positioned near the top of the Oil
Separation Chamber (12) which allows the thin layer of surface oil and water to drain into the Waste
Oil Decanter (14). Since oil is lighter than water, the oil oats to the top and is released from the
Waste Oil Decanter (14) when the Waste Oil Release Valve 2 is opened. Excess water is returned
to the Wash Water Catch Pit (1).
2) The solids that accumulate in the bottom of the Solids Separation Chamber (9) will be drained
weekly (factory set) through the Automatic Solids Drain Valve 3 into the Sludge Tub (15) where the
solids are ltered out and the water is returned to the Wash Water Catch Pit (1). The Filter Bag (16)
is biodegradable and may be tied o and disposed of as it is lled. Note that the Manual Solids Drain
Valve 4 should remain in the open position during normal operation. If the solids accumulated at the
bottom of the Solids Separation Chamber (9) are unable to drain, open Valve 5 and Valve 6 to push
the solids towards the Sludge Tub (15). If the solids are still unable to drain, open Valve 7 and Valve
8 to break up the solids on the inside of the Solids Separation Chamber (9). When the solids from
the Solids Separation Chamber (9) is emptied, close Valve 5, Valve 6, Valve 7 and Valve 8.
3) An Anti-siphon Device (17) is attached to the Inlet Tee (6) to relieve any suction that may develop
when the Sump Pump (4) is turned o, preventing any siphoning of water back out of the water
clarication tank.
Water then ows through the Ozone Pump Valve 9 down past the Sensor Probes (18 & 19) then into the Ozone
Pump (20) where it is forced through the Ozone Injector (21) and back up into the Oil Separation Chamber (12).
(See “pH & ORP Control System” for details.)
1) Ozone is generated by oxygen molecules passing through a corona discharge Ozone Generator (22).
This is an electric charge which causes the oxygen atoms to become ozone molecules. Since ozone
molecules are extremely unstable, they only retain their structure for a very short time. For this reason,
ozone cannot be stored, but must be continually produced by the Ozone Generator (22).
2) Ozone kills bacteria approximately 3,000 times faster than chlorine.
3) The ow of ozone is controlled by the Ozone Flow Control Valve 10.
Water then ows from the Oil Separation Chamber (12) through the Outlet Ring (23) and into the Outlet Y (24). The
Outlet Y (24) directs the water into the Holding Tank (25) where the Filter Pump (26) sends the water to the Filter
Control Valve 11 which regulates the amount of water going into the ltering system. (Flow is factory set at 30 gallons
per minute.) A Flow Meter (27) is positioned just ahead of the Multi-Media Filter (28) to monitor ow. The Multi-
Media Filter Valve 12 has two positions: Filter and Backwash. When in the “Filter” Position, water ows into the Multi-
Media Filter (28) from the top and passes through several layers of ltering product as it moves toward the bottom. By
the time the water reaches the bottom to the lter tank, the contaminants have been ltered down to approximately 20
microns. Laterals are positioned at the bottom of the lter tank, which absorb the ltered water and move it up through
the center and out the side of the tank. From there, the water ows into the Polishing Filter Valve 13. This valve has
two positions: Filter and Backwash. When in the “Filter” position, water ows into the Polishing Filter (29) from the
top and passes through the activated carbon or ltering agent. As it moves toward the bottom, the activated carbon
or ltering agent absorbs odor and contaminants while “polishing” the water. Laterals are positioned at the bottom
of the tank, which absorb the water and move it up through the center and out the side of the tank. From there, the
water moves to the Product Tank (30) where the recycled water is held until usage is required. When needed, water
is pulled from the Product Tank (30) by the Transfer Pump (31) and moved into the Pressure Tank (32). This tank
holds water at 30-50 PSI/2.0-3.5 Bar. Water moves directly from this tank to the water discharge outlets upon demand.
If water is needed for washing, water is sent to the Outlet To Pressure Washer (33). If the Wash Water Catch Pit
(1) water level is low, water is added through the Fresh Water Makeup (34). If the Wash Water Catch Pit (1) water
level is too high, water is sent to the Rain Water Overow (35). If the recycle timer turns on, water is sent through the
Recycled Wash Water (36) to the Wash Water Catch Pit (1).

PREPARATION
PRESTART PROCEDURES:
1. Position the valves on the WCP water recycling treatment system in the "Start-up Mode".
-Water Inlet Flow Control Valve: Turn valve one rotation short of completely closed.
-Filter Control Valve: Turn valve one rotation short of completely closed.
-Air Bleed Valves: Turn valves open.
-Oil Release Valve: Turn valve completely closed.
-Ozone Pump Valve: Turn valve open.
-Pressurized Clean-Out Valves: Turn valves completely closed.
2. Be certain all hoses are securely connected.
3. Be certain the incoming air tube to the Ozone Generator is not obstructed.
4. Be certain all switches on the Control Panel and Ozone Generator are in the "OFF" position.
5. Turn on the power supply. The Power Indicator Light should glow.
START-UP:
1. Ensure water supply to the Fresh Water Makeup is turned on and pit is lled with water. If the pit is not full, water
will ll the Product Tank and overow through the Product Tank Overow and back to the Sump Pit.
2. To prime the Sump Pump, remove the lid over the Basket Strainer and ll the Basket Strainer and the plumbing
from Sump Pit to the Sump Pump with water, then replace the lid.
3. Turn on the Sump Pump Switch; water will ow into the Clarier Tank.
4. Flow can be increased by opening the Water Inlet Flow Control Valve and reading the Inlet Flowmeter. Fill the
Clarier Tank.
5. After the water lls the Solids Separation Chamber, it will begin to ow through the Top Separator Cone and ll
the Oil Separation Chamber.
6. As water lls the Oil Separation Chamber, the Ozone Pump will prime.
7. When the Oil Separation Chamber is full, the water will begin to ow through the Outlet Ring and into the
Outlet Y.
8. The Outlet Y directs the water into the Holding Tank where it is ready to be processed.
9. As the water lls the Holding Tank, it will begin to ow out the Overow Drain at the top of the tank. At this point,
ow can be adjusted with the Water Inlet Flow Control Valve. Set the ow rate to 30GPM. If the oat rises and turns
o the Sump Pump, reduce the ow rate with the Water Inlet Flow Control Valve.
10. Ensure that the Ozone Pump Valve is open and turn on the Ozone System Switch located on the main control
panel. The ozone system is working properly when air bubbles are seen in the Oil Separation Chamber. If no air
bubbles are observed, turn o the Ozone System Switch and loosen the union after the Ozone Pump until the
pump is primed. (The Ozone Flow Control Valve is set at the factory and should not need adjusting.) The Ozone
Generator Switch can now be turned on.
11. Turn on the Filter Pump Switch. The Filter Pump will automatically turn o when the Product Tank is full of
water.
12. As water ows to the lters, use the Filter Control Valve to adjust the water ow to the 30GPM. Check the Filter
Flowmeter located ahead of the Multi-Media Filter.
13. Water will begin to ow from the Multi-Media Filter to the Polishing Filter. As water ows through the Multi-Media
Filter, air will automatically bleed from the Multi-Media Filter to the Polishing Filter.
14. As water ows through the Polishing Filter, air will also automatically bleed from the Polishing Filter to the Product
Tank. Air can also bleed from both lters by opening the Air Bleed Valve on each lter.
NOTE: DO NOT attempt to backwash the lters until all of the air is bled from the system.
15. When the Product Tank is full and the Filter Pump turns o, prime the Transfer Pump by opening the Outlet to
Pressure Washer valve until water exits.
16. Turn on the Transfer Pump Switch to allow water to ow into the Pressure Tank. The Transfer Pump will run until
the pressure system reaches 50PSI. This can take up to 7 minutes.
17. Water is now completely cycled in the system.

pH AND ORP CONTROL SYSTEM:
Proper pH and ORP levels must be maintained in the pit to prevent growth of bacteria, algae, odors, etc. Water must be
chemically balanced to eectively recycle. The eectiveness of the OPR agent in the water depends on the pH level.
-The optimum pH level to add the OPR agent is 6.5 - 6.8.
-As the pH level rises to 7.5, about 5% more OPR agent must be added to achieve the same ORP reading.
-At a pH level of 8.0 and above, a large amount of OPR agent must be added to increase the ORP reading.
As excess water ows through the Ozone System , it moves past the pH and ORP Sensor Probes before returning
to the Oil Separation Chamber . The Sensor Probes analyze the pH and ORP levels in the water.
a. pH Sensor Probe. This probe analyzes the pH (acidity & alkalinity) in the water. If the water is too acidic (low
pH) the acid will breakdown the iron present in the water to a liquid form, thus causing rusty looking water in the
system. If the water is too alkaline (high pH) the bacteria killing potential of the ORP agent will be drastically
lowered.
b. ORP Sensor Probe. This probe analyzes the Oxidation Reduction Potential (ORP). This reading states amount
of bacteria killing agent in the water.
The probes analyze the pH and ORP levels of the water and display the readings on the digital pH and ORP Meters.

SETTING THE TIMERS:
Two timers are located in the main area of the unit control panel. The rst is
an electronic timer used to operate the clarier drain valve. Second is a time
switch used to operate the water recycling system and the auto-backwash
system. These timers have been pre-set at the factory.
ELECTRONIC TIMER:
A simple Phillips head screwdriver can be used to make the adjustment here.
Available settings on both range setting adjustments are:
1 second, 3 seconds, 10 seconds, 1 minute, 3 minutes, 10 minutes, 1 hour,
3 hours, 10 hours, and 60 hours.
The time dials determine the percent value of the range settings from 0 to 1.0.
As an example, if the range setting is at 10 hours, and the corresponding time
dial is at 0.8, then the value for that function is 80% of 10 hours, or 8 hours.
Range setting/ timer dial setting one determines the frequency of the timer
activation. It is set to activate every 8 hours. Range setting/ timer dial setting
two determines the duration of the timer activation. Duration of the dump
cycle is set for 8 seconds. The slide switch should remain in the up position.
TIME SWITCH:
The time switch is used as a dual functioning timer. The rst function (C1)
is set to activate the auto-backwash system once a day at 9 PM. Secondly,
the time switch is used to activate the water recycling system (C2) once a
day at 2 AM. If the water in the recycle system lies dormant for more than
six hours, it tends to become stagnant and odorous. Dependant on use, you
may need to add one or two more daily cycles to this timer program
When setting the time switch, a program must be entered for both the turn on
time and the turn o time. Each on cycle and o cycle count as one program.
There are 42 programs available on this time switch. FOR COMPLETE
PROGRAMMING INSTRUCTIONS FOR THE TIME SWITCH, PLEASE

1. The Oil Skimmer removes the top layer of oil and water from the Oil Separation
Chamber and sends it to the Waste Oil Decanter.
2. As the Waste Oil Decanter lls with the oil/water mixture, the oil will oat to
the top while the water remains on the bottom.
3. The water then moves up the standpipe, through the Oil Decanter Outlet,
and back to the Wash Water Catch Pit to be recycled again.
4. As oil accumulates, it will have to periodically be removed from the Waste
Oil Decanter.
a. Place a 5 gallon bucket below the hose on the Waste Oil Release Valve
b. Open the Waste Oil Release Valve and allow oil to ow into the 5 gallon
bucket. Turn o valve when water begins owing into the bucket.
c. Dispose of oil according to EPA Standard
SOLIDS COLLECTION AREA:
The solids collection area of the Solids Separation Chamber will need to be
cleaned occasionally to prevent overow of solids into the Holding Tank.
1. Ensure the Sludge Hose is connected to the Sludge Tub and the Sludge
Outlet Assembly and a Filter Bag is secured in the Sludge Tub.
2. The unit will automatically backwash once for each pin that is pulled out on
the Clarier Drain Valve Timer (See Setting the Timers to adjust).
3. The Clarier Drain Valve can be opened manually by turning the Clarier
Drain Valve Switch to the "ON" position. The valve will remain open until the
switch is turned to the "OFF" position.
4. If the solids accumulated at the bottom of the Solids Separation Chamber
are unable to drain, open Valve 4 and Valve 5 to push the solids towards the
Sludge Tub. If the solids are still unable to drain, open Valve 6 and Valve 7 to
break up the solids on the inside of the Solids Separation Chamber. When
the solids from the Solids Separation Chamber is emptied, close Valve 4,
Valve 5, Valve 6 and Valve 7.
5. As sludge is forced into the disposable Filter Bag, solids in the Sludge are
retained by the disposable Filter Bag and uids drain out into the area created
by the Riser Plate.
6. The remaining water drains out of the bottom of the Sludge Tub through Sludge
Tub Outlet and back to the Wash Water Catch Pit.
7. When the Filter Bag is lled with accumulated solids, loosen the Hose Clamp
used to retain the Filter Bag, tie the Filter Bag o and dispose of in a manner
consistent with local and federal regulations.

I. TEST PROCEDURE A: For systems with pH & ORP Control, your test kit will include test strips.
A. Following the directions included with the test strip kit, test the water in the Holding Tank.
1. The test strip should show chlorine present in the system.
2. If no chlorine is present, check the following:
a. The ORP Adjustment Chemical is empty. Replace.
b. The ORP Pump is turned o or malfunctioning. Ensure the ORP Pump Switch is in the ON
position. Contact your local distributor if additional maintenance is needed.
c. If you are not using chlorine as an ORP control, you must refer to TEST PROCEDURE B to ensure the
carbon is still active.
B. With the Filter Pump operating, use a test strip to test the incoming water to the Product Tank.
1. The test should not show chlorine present in the system.
2. If chlorine is present, the carbon must be replaced. See REMOVING AND REFILLING MEDIA section.
II. TEST PROCEDURE B: For systems without pH & ORP Control, your test kit will include a Carbon removal scoop,
4 oz. empty container, 2 oz. empty container, 2 oz. bottle of chlorine, Chlorine test paper with color chart. Contact
your local distributor if any parts are missing.
A. Turn o the Filter Pump Switch.
B. Unscrew the cap and remove the Polishing Filter Valve.
C. Fill the Carbon Removal Scoop with a sample of carbon from the Polishing Filter tank.
D. Add 2 oz. of the carbon sample into the 4 oz. empty container.
E. Fill the 2 oz. empty container with water.
F. To the water, add one drop of chlorine.
G. Follow the directions on the bottle of test strips. Dip a chlorine test paper into the 2 oz. container. The chlorine
reading should be at least 10 parts per million. If not, add another drop of chlorine.
Backwash Mode:
In backwash mode the slide valve is in the down
position. The air solenoid actuates forcing
compressed air to the top of the slide valve air
cylinder. The air pushes the air cylinder plunger
down, pushing down the slide valve shaft. Discs
on the slide valve direct water ow from the lter
inlet to the bottom of the lter pod. Water travels
upwards through the media to the top and out the
backwash line.

WCP Automatic Backwash Series Operator's Manual
H. Add the 2 oz. of chlorine/water solution to the carbon sample in the 4 oz. container.
I. Tightly cap the chlorine/carbon mixture and shake occasionally for 3 minutes.
J. Dip a new strip of chlorine test paper into the liquid part of the 4 oz. container. Do not dip the test paper into the
solid carbon as this will produce incorrect results. Read the directions on the bottle of test strips.
K. Check the reading against the color chart.
1. A reading of zero means the carbon is still active.
a. Reassemble the dispersing section of the Polishing Filter and replace the Polishing Filter Valve.
b. Turn the Filter Pump Switch on.
2. A positive reading means the carbon is inactive and must be recharged or replaced.
REMOVING & REFILLING MEDIA FROM THE MULTIMEDIA & POLISHING FILTER:
1. New media can be ordered from your local distributor using the part numbers listed below.
2. Be certain to wear proper attire such as goggles, gloves, coveralls, dust mask, etc. to protect eyes and skin.
3. Turn o the Filter Pump Switch.
4. Remove the top from the desired lter tank using the wrench provided.
5. Use a vacuum to remove the media from the lter.
6. Ensure the lateral assembly remains centered and ush on the bottom of the tank and the layers are level when
pouring media into the lter tank.
7. Reassemble the dispersing section of the lter tank and replace its corresponding valve.
8. Turn on the Filter Pump Switch. DO NOT backwash Multi-Media Filter until unit has been in operation for 24 hours.
9. Dispose of used media according to EPA standards.
SLIDE VALVE:
The Slide Valve needs to be disassembled so the o-rings can be greased on a monthly basis. Mi-T-M recommends
using a water proof grease and apply the grease liberally.

MAINTENANCE:
1. Clean pH AND ORP probes every 1-2 months.
a. Shut o sump pump, wait for drain line to dran and loosen aluminum strain relief around probe to remove.
b. Use water or vinegar and a soft cloth or Q-tip to wipe away build up on the probe.
c. Place probe back in line, with tip at center of piping. Tighten strain relief around probe. DO NOT OVERTIGHTEN.
Note: probes will be damaged if they are allowed to dry out. If they will be exposed to air for more than a few
hours keep tip submerged in water or the storage solution that comes with the probe.
Note: probes have a shelf life of about 1 year so it’s recommended to replace the probes yearly.
2. Calibration of pH meter. You should recalibrate the external meter 1 or 2 times a year. You should also always
recalibrate the meter when a pH probe has been replaced. Follow the calibration instructions below for the pH meter.
An electronic calibrator can be used in place of the buer solutions.
MAINTENANCE
WATER TESTING:
Water chemical makeup should be tested on a weekly basis. With the Sump Pump operating, use a test strip, test
the incoming water to the Holding Tank. (Follow the directions given with your test strips.) Use the ow chart below
to check and correct the following:
1. pH: Acidity and alkalinity in the water. Low pH (acidic) will cause rusty looking water.
2. Alkalinity: Dissolvable salts in the water. Too much alkaline causes cloudiness and reduces lter life.
3. Calcium Hardness: Calcium in the water. Too much calcium creates scale buildup in coils of hot water pressure
washers.
4. *Free Chlorine: Chlorine which is not combined with dirt, oils, etc. Controls odor, bacteria and algae formation.
*If using chlorine as a water purifying agent.
