this machine. The dealer is also responsible for initial
training of your operators and maintenance personnel
in proper operation and maintenance of this unit.
Vehicle Requirements
1. The unit should NOT be mounted in any motor
vehicle of less than 1/2 ton capacityor 3/4 ton if
equipped with one or more auxiliary fresh water
tanks.
DO NOT exceed the vehicle’s axle weight limit.
Include the console, full tanks, accessories, and
operators in calculations.
2. If mounting in a trailer, make certain that trailer is
rated for the total weight of UNIT AND TRAILER.
Electric or hydraulic brakes should be provided,
and a strict compliance with any State and Federal
vehicle laws must be maintained.
3. The vehicle tires should have a load rating above
the combined vehicle and unit weight.
4. We do not recommend using flooring materials that
absorb water. This could result in rust and
corrosion of the vehicle floor.
5. Padding under rubber floor mats should be
removed before installing this unit.
Lifting Unit Onto Vehicle
Since console weighs approximately 600 lbs. pounds,
(690 lbs. if mounted on water tank) we recommend
using a forklift to lift unit onto vehicle. Position forks
under unit from front and make CERTAIN that forks are
spread to insert into frame slots.
Positioning Unit In Vehicle
Because vehicles vary in size and openings, individuals
have their own preference as to where they want their
units installed. We strongly recommend a side door
installation for this and DO NOT recommend a rear
door installation.
1. Enough space should be provided to assure
adequate engine ventilation and room for service
and maintenance.
2. The unit with waste tank and accessories must
NOT exceed vehicle's axle weight limit. An empty
60 gallon waste tank and console weighs 810 lbs
(900 lbs. if mounted on water tank).
3. DO NOT position the console closer than 12" from
bottom of driver and passenger seats.
NOTE: For individuals who wish to make an
engineering layout prior to positioning unit, refer to
"Dimensional Data" illustrations for waste tank and
console dimensions.
4. Be sure to consider all accessories and their
required space prior to positioning the console and
waste tank.
6. We highly recommend using a drip tray under
console (Part #86050370, or Part # 86050380 for
units mounted on a water tank).
7. If using a trailer, console should be positioned so
that it balances properly with respect to axle. Ten
percent (10%) of the overall unit weight, should be
on tongue.
Example: If loaded trailer weight is 2,000 lbs.,
tongue weight needs to be a minimum of 200 lbs.
to tow properly.

Fuel Requirements
Use unleaded gasoline ONLY. DO NOT use any
gasoline additives. We recommend the use of clean,
fresh, unleaded gasoline intended for automotive use.
High octane gasoline should NOT be used with the
engine on this unit. These engines are NOT designed
to use E-85 or Flex Fuels.
Engine Oil Requirements
Use high quality detergent 10W-30 oil of at least API
(American Petroleum Institute) service class SG, SH,
SJ or higher.
NOTE: Using a lower service class oil or extending oil
change intervals longer than recommended can
cause engine damage.
NOTE: Synthetic oils meeting the listed
classifications may be used with oil changes
performed at recommended intervals. However to
allow piston rings to properly seat, a new or rebuilt
engine should be operated for at least 50 hours using
standard petroleum based oil before switching to
synthetic oil.
Altitude Requirements
Engines perform differently with increases/decreases in
altitude. Be sure to check engine speeds during initial
installation. See engine speeds in Technical Specifications section.
NOTE: To ensure correct engine operation at
altitudes above 1525 meters (5000 ft.), it may be
necessary to have an authorized dealer install a
special high altitude jet kit in the carburetor. If a high
altitude kit has been installed, the engine must be
reconverted to the original jet size, before it is
operated at lower altitudes, or overheating and
engine damage can result.
Chemical Requirements
This cleaning unit, due to its chemical injection pump
design, can be used with a variety of water-diluted
chemical compounds (either acidic or alkaline),
depending on the job to be done. However, to obtain
optimum results with this unit, we recommend using the
PROCHEM line of chemicals. For information on using
the cleaning compounds, refer to the chemical manual.

Water Requirements
Hard water deposits will adversely affect the plumbing
and heat exchange systems on this unit. The map
below will give you an idea of where areas of high water
hardness may occur. However, any water supply
obtained from a well is almost always hard water and a
water softener will be needed to protect your equipment.
NOTE: Equipment malfunction or component failure
caused by hard water scaling is NOT covered under
the warranty.
If you are operating this unit in an area where the unit
will be using water in which the harness exceeds 3-1/2
grains, we highly recommend a suitable water softener
be installed. If using a water softener, it must have a
five (5) GPM (or greater) flow capacity without any hose
constrictions.
Using a water softener will reduce maintenance and
decrease down time caused by hard water scaling. It
will also allow cleaning chemicals to be more effective
in lower concentrations
If you require a water softener, your dealer has a model
to meet your needs. Please contact your nearest
distributor for information, price, and abailability.

Vacuum System
The engine turning the vacuum pump generates
vacuum. The air is channeled in one side of the
vacuum pump, compressed and discharged on the
opposite side, creating airflow.
The movement of air is used to do the work necessary
for the extraction process. A vacuum nozzle applied to
the carpet surface removes moisture, dirt and spent
chemicals. These elements are conveyed back to a
separating tank utilizing hoses and the force of air.
Particles of moisture and dirt are separated in the
vacuum tank using a series of changes in direction and
velocity. The air is then filtered and rushes into the
vacuum pump.
The vacuum pump compresses and heats the incoming
air. The hot discharged air is forced down stream into a
silencer for noise abatement. After exiting the silencer,
this hot air is mixed with hot air exhaust gases from the
engine. This mixture of hot air and gases are then
forced through 3 radiators serving as heat collectors.
Heat from the engine and vacuum pump is then transferred into the plumbing system raising the water
temperature for better cleaning.
The vacuum pump speed is factory set to maximize
vacuum pressure and provide sustained system life.
Do not alter the vacuum speed outside the recommended range shown in the Technical Specifications
section.

Heat Exchanger
Always wear hearing protection and proper
personal protection equipment when operating
unit.
Water Pumping and Heat Transfer System
Cold water enters the console through the water inlet.
When the water box is full the valve will automatically
shut off.
Water then flows from the water box, through the
strainer, into the solution pump. The water is pumped to
the pressure regulator manifold, which provides and
maintains the desired pressure setting.
The pressure regulator manifold includes a pulse hose,
which helps reduce pressure spikes from the pump.
A certain amount of water is by-passed from the
pressure regulator due to over pumping capacity of the
solution pump. Water that is not called for in the
cleaning process is channeled through a copper heater
core in the front of the heat exchanger box. This bypass
water circulates several times through the heater core
pre-warming the water.
The water temperature in the plumbing system is raised
for better cleaning. This happens in the heat
exchanger. The heat exchanger is made up of three
stages. These three stages are engine exhaust stage,
the mixing stage, and the pre-warming stage.
The angled rear heat exchanger core receives its heat
only from the engine exhaust gases. This core
becomes extremely hot and should not be touched
while the machine is in operation. Allow the machine to
cool down completely before attempting to service this
area.
The middle core receives its heat from the mixing of
both the engine exhaust and the vacuum pump
exhaust. The vacuum pump heats incoming air as it is
compressed. This hot air is mixed with the hot engine
exhaust gases exiting the angled rear core. This
mixture of hot air and gases is then forced through the
middle core and on through the front heat exchanger
core.
The front core continues to extract heat from the mixed
gases; but, this heat is used to pre-heat the water box
as a preliminary hot water reservoir.
The gases coming from the vacuum pump and the
engine exhaust are forced through the middle and rear
heater core creating the hottest area of the heat
exchanger box, and increasing the heat transfer to the
circulating water.
The hot water passes to the solution outlet manifold
where cleaning chemicals are injected from the
chemical pulse pump. This manifold serves as a
connecting point for the high-pressure hoses. Also a
check valve is located in this outlet manifold prohibiting
chemicals from backing up into the system.
The cleaning solution then passes through highpressure solution hoses and is distributed by the
cleaning tool to a surface that is being cleaned,
completing the water pumping and heating cycle of the
cleaning unit.

Chemical Injection System
The chemical injection system is unique in that it
utilizes the pressure spikes generated by the high
pressure solution pump to move chemical into the main
solution stream. The high pressure spikes move the
diaphragm in the chemical pulse pump forcing small
amounts of liquid chemical to be moved in a single
direction of flow with the aid of two check valves.
The chemical is drawn from the container, and through
the flow meter, which indicates rate of flow. The
chemical then moves to the chemical pulse pump
where it is pressurized.
The chemicals flow to the chemical selector valve,
which can turn off the chemical flow or when set to
"Prime" sends it into a bypass loop to purge air from the
system, or when "CHEM" the chemical can be directed
to the metering valve. The metering valve controls the
amount of chemical that enters the solution outlet
manifold.
The manifold assembly's check valve will not allow the
chemicals to travel upstream into the plumbing system
of the unit. The chemicals are mixed there with hot
pressurized water that makes a cleaning solution. The
solution then flows to the outlets for cleaning.

container.
3. Pull out engine choke, turn solution pump switch to
override and turn ignition key to start.
4. Push in engine choke after engine has started.
5. Set throttle to idle position.
6. Turn on solution pump.
7. Turn chemical control valve to prime and allow
chemical to circulate. After all air bubbles have
been removed from chemical tubing, turn the valve
to the horizontal (off) position.
8. Turn the chemical control valve to run. use the
chemical metering valve to set the chemical flow to
the desired flow rate while observing the flow meter
indicator. To accurately set the chemical flow, pull
the trigger on the cleaning tool while adjusting the
flow rate.
9. Set throttle to maximum position for quick unit heat
up.
NOTE: Do not run the machine with the port blocked
for more than 2 minutes to avoid overheating.
Once you have completed priming the chemical pump,
proceed with the cleaning operation. Your unit should
be in the correct throttle position for your cleaning
operation or extracting.
Always dispose of waste in accordance with Local,
State, and Federal laws.
Waste Pump (Optional)
1. If your unit is equipped with an automatic waste
pump, connect one end of a garden hose to the
pump-out connection and the other end to an
appropriate waste disposal.
2. Turn the pump-out switch on the control panel to
the ON position. The waste pump will operate automatically throughout the cleaning operation.
We recommend that you use a 3/4" I.D. water hose as
a waste pump outlet hose. DO NOT use a hose smaller
than 5/8" I.D.
NEVER use your automatic waste pump outlet hose as
a water inlet hose.
Cleaning
Observe the following guidelines, while cleaning:
1. Before proceeding make sure the spray tips are
functioning properly.
a. To check, hold the wand about one foot above the
surface to be cleaned and open the wand valve. A
full spray should be observed from all of the spray
tips.
b. If the spray tips are not showing a full spray pat-
tern, adjust for proper pattern, clean, or replace
spray tips, if required.
32
2. Normally chemical is applied on the push stoke of
the wand when cleaning and vacuuming is done on
the pull stroke. For heavily soiled carpets the wand
may be used in a scrubbing manner, applying
chemical in both push and pull strokes. Always finish up an area with a vacuum stroke.
3. When cleaning, keep the working opening (mouth)
flat on the surface being cleaned. Keep the wand
moving when the valve is open.
4. The unit will automatically shut-down when the
waste tank is full. This will prevent water being
drawn into the vacuum pump. If shut-down occurs,
empty the waste tank before proceeding. If shutdown occurs due to foam created by chemicals
used, add Prochem defoamer.

Upholstery Cleaning
Upholstery tool, (See Options Section)
1. To protect fabrics, reduce solution temperature as
needed by opening the solution temperature control valve on the lower front panel. Engine speed
may also be reduced slightly to reduce heat and
vacuum.
Shutdown and Daily Maintenance
1. Close chemical metering valve.
2. Allow the unit to run for 2 minutes with the vacuum
hose disconnected to remove moisture. Spray
water displacing lubricant into the vacuum lubrication cup. This will prevent corrosion due to moisture.
3. Set engine throttle at idle position and allow the
water temperature to cool down, utilizing the temperature control valve in the open position to bleed
off residual hot water left in the system.
4. Close temperature control valve and turn off ignition switch.
5. Disconnect all hoses and tools.
6. Drain waste tank and rinse with clean water.
De-Flooding Operations
De-flooding operations involve removal of water from
carpet and flooring. This differs from normal cleaning
operations in that no water or solution is required. An
automatic waste pump-out is highly recommended for
all de-flooding operations due to the large amount of
water removal often required.
Freezing Protection
If the unit is exposed to freezing weather the water
in the unit may freeze, causing SERIOUS DAMAGE
to the unit. To avoid this, the following is recommended during the cold weather season.
When the unit is not in use, always park it in a heated
building.
While in operation, avoid long shutdowns as the unit
provides heat while running. Shut it down just prior to
leaving for the next job.
If a heated building is not available, we recommend that
you winterize the unit with anti-freeze. At present, it is
only possible to winterize units, which do not have an
auxiliary water tank. Units with auxiliary water tanks
must be stored in a heated building when not in use.
Overheating Protection
Air cooled engines rely on the flow of air over the
engine for cooling operations. Ensure that there is
sufficient air flow in the van. Never operate the unit
with all the vehicle doors closed and no alternative
ventilation system.
This unit must be operated with the vehicle or
trailer doors open in order to ensure adequate
engine ventilation.
1. Start unit.
2. Set pressure regulator at 100 psi.
3. Shut off solution pump.
4. Begin de-flooding operations.
5. Under almost all conditions, the unit will sufficiently
cool itself. If you find yourself operating in extreme
heat: Hook up a water supply; turn on the water
pump at 100 psi, and crack the temperature control
valve slightly to provide additional cooling to the
solution system.

tool valve until water pressure drops.
4. Turn off solution pump. Fill the water box with
approximately two gallons of 100% glycol base
anti-freeze.
5. Turn the solution pump switch ON.
6. Open the tool valve until anti-freeze begins to
come out of the tool. Recover ALL anti-freeze that
comes out of the tools into an approved container.
We strongly recommend that you re-cycle and reuse the anti-freeze.
Repeat this procedure with all the remaining tools. After
all tools and pressure hoses have been filled with antifreeze, disconnect and store them.
7. Turn the solution pump switch OFF. Attach the
winterizing loop hose with attachment, Part
#86260700, to the solution outlet connection and
the water inlet connection. Turn the solution pump
switch ON.
9. Prime the chemical system with 50/50 anti-freeze/
water mix. Insert the chemical inlet and prime
discharge tubes into the anti-freeze container.
Turn the chemical valve to PRIME until anti-freeze
begins to flow out of the prime hose.
10. Turn the chemical valve to the open position,
making certain that the flow meter indicates flow
and that all anti-freeze drains out of the chemical
hose into an approved container, after 30 seconds,
turn off both valves.
Allow the unit to run for approximately 3 minutes with
the winterizing loop hose attached.
8. Open temperature control valve and allow antifreeze to flow to waste tank.

Removing Anti-Freeze From the Unit
1. Connect the water inlet hose to the water inlet
connection on the console. Turn the water supply
on.
2. Start unit turn on pump.
3. Connect all solution hoses and any tools which
require purging of anti-freeze to the solution outlet
connection(s).
4. Open the tool valves and drain the anti-freeze into
an approved container until the flow is clear and all
anti-freeze is purged from the tools and hoses.
5. Place the chemical prime hose into the approved
container. Submerge the chemical inlet hose in
water. Turn the chemical valve to the PRIME
position until clear water comes through the prime
hose, and then remove the prime hose from the
container.
6. Turn the chemical valve to the ON (CHEMICAL)
position. This will allow water to flow into the other
side of the system.
Once all of the anti-freeze is removed, the unit is ready
to use.
Eventually, the anti-freeze in your storage container will
become diluted with water. If the anti-freeze level drops
below 50% of the total, dispose of it and start with fresh
100% anti-freeze.
When disposing of used anti-freeze, observe local
laws and regulations. Do not drain onto the ground
or into storm drainage systems.

Maintenance
Key Checkpoints
NOTE: Initiation of a planned preventative
maintenance program will assure that your unit has
optimum performance, a long operating life, and a
minimal amount of "down" time.
External Fuel Pump Maintenance
The power plant for the unit receives fuel from the main
fuel tank of your van/truck. An external fuel pump that
provides this fuel is located on the underside of the van/
truck. Loose fittings and hose connections will cause
your unit to perform poorly. Follow the recommended
fuel pump maintenance in the Maintenance Schedule
in this manual. Refer any additional questions to your
dealer.
Chemical Supply System Maintenance
The chemical supply system pulls chemicals from your
chemical bottle utilizing a pump that works off the water
pump pulsing. Any clogged filters or loose connections
will result in a chemical supply system malfunction or a
malfunction at the cleaning tool. Maintenance of the
solution outlet check valve and screen are vital to
effective cleaning operation and minimal unit downtime.
Additionally, the hoses related to supplying water and
chemical to the outlet manifold are under high
pressures and experience thermal expansion and
contraction. Periodic inspections of these hoses for
tears, cracks, and failing connectors are necessary to
avoid unwanted leaks. To keep your chemical system
functioning properly, follow the chemical pump and
solution outlet maintenance in the Maintenance
Schedule in this manual. Refer any additional
questions to your dealer.
Heat Exchanger System Maintenance
The heat exchange system in your unit transfers
energy from the engine’s exhaust and blower discharge
air to the solution supply system. The heat transfer of
this system is highly dependent on the surface area
contact in the heat exchanger cores located in the heat
exchanger box. This surface area amount is adversely
minimized when the supplied water is not softened to
recommended levels. Hard water will result in scaling
on the inside walls of the heat exchanger tubes. It is
recommended that you use a manufacturer approved
water softener to avoid premature heat exchanger core
failure. Contact your local dealer for advice on the
water hardness levels in your area.
Additionally, the heat exchanger tubes are very
sensitive to freezing conditions. As the water freezes
during cold conditions, it expands in the heat
exchanger tubes and causes damage. Often the tubes
are cracked and require the replacement of the heat
exchanger core. Refer to the Freeze Protection instructions section in this manual. Refer any additional
questions to your dealer.

Vacuum Pump Maintenance
(Refer to pump manufacturer’s manual for specific
maintenance instructions)
The total function of the unit is based around the performance of the vacuum pump. Heat transfer used to
raise the temperature of the solution is gained from the
air drawn by the vacuum pump and solution is removed
from the carpet with the vacuum suction of the vacuum
pump. General maintenance actions for the vacuum
pump as listed in this manual are vital to prolonged
vacuum pump operations. Daily lubrication of the
pump is required to avoid seizure of the system. Also,
waste tank filters and strainers must be maintained to
prevent unwanted debris from entering the vacuum
pump.
DO NOT service this unit while it is running. The
high-speed mechanical parts as well as high
temperature components may result in severe
injury, severed limbs, or fatality.
NOTE: Use the hour meter as a guide for coordinating
the maintenance schedule.
Engine
(Refer to engine manufacturer’s manual for specific
instructions)
1. Check the engine oil level daily, when in use.
Make certain that proper oil level is maintained.
NEVER overfill.
2. Change the break-in oil and filter after the first 8 hours of operation. Thereafter, change oil and oil
filter every 100 hours of operation. USE ONLY
ENGINE MANUFACTURER’S BRAND OIL FILTERS. ANY OTHER TYPE OIL FILTER WILL
VOID YOUR ENGINE WARRANTY. Torque drain
plug to 10 ft lbs.
Oil Recommendation. See “ENGINE OIL REQUIREMENTS” in Operations section.
NOTE: Using other than service class SG, SH, SJ
or higher oil or extending oil change intervals
longer than recommended can cause engine
damage.
3. Check the spark plugs every 200 hours. Clean if
necessary. Replace the spark plugs every 1000 hours. NOTE: Never sandblast spark plugs.
Spark plugs should be cleaned by scraping or wire
brushing.
4. Replace the air cleaner element every year.
5. Replace the in-line gas filter every 500 hrs.
NOTE: For additional engine service information,
obtain the engine manufacturer’s manual from any
authorized service center. If service or repair is
required, contact an authorized engine
manufacturer’s service center. You will need to

Vacuum Pump
Refer to the Vacuum Pump Operation and Service
Manual for specific instructions.
Lubrication: We recommend that you use Tuthill
Pneulube synthetic lubricant. Tuthill Pneulube
synthetic lubricant is formulated especially for Tuthill
rotary positive displacement blower service to provide
maximum protection for all operation temperatures
NOTE: Tuthill Pneulube synthetic lubricant is the oil
which PROCHEM puts in the vacuum pump at the
factory. Topping off or adding petroleum oil to
synthetic oil is NOT recommended.
1. Check the oil level daily to assure the proper level.
PROPER LEVEL cannot be overemphasized. Too
little oil will ruin bearings and gears. Too much oil
will cause overheating. Use the illustration as a
guide when adding oil.
2. To prevent rust from building up inside the vacuum
pump (if moisture exists) we have provided a lubrication cup on the front of the unit.
First run the unit at least 1 minute to remove any
moisture from the vacuum pump. Next, fill the
lubrication cup with water displacing lubricant, for
5 seconds while the unit is running and the vacuum inlets are sealed. Do this at the end of each working day.
3. Drain, flush and replace oil every 1000 hours or yearly, whichever comes first. Change oil more
frequently if inspection so indicates.
Vacuum pump oil capacity is approximately 10.5
ounces.
4. Vacuum pump lubrication is vital to performance of
our pump. Failure to follow the maintenance
schedule in the “Maintenance Schedule” can lead
to permanent damage to your blower.

Vacuum Inlet Filter (in Waste Tank)
1. The vacuum filter in the waste tank should be
removed and cleaned daily. If this is done, the filter
will last for a long period of time.
Vacuum Relief Valve
While the unit is running at full RPM, block the air flow
at the vacuum inlet connection and read the vacuum
gauge. If adjustment is required, shut the unit down and
adjust the vacuum relief valve locking nut tension. Start
your unit and read the vacuum gauge. Repeat this
process until the relief valve opens at 13" Hg.
Vacuum Pump Drive Belts
To tighten the vacuum pump belts:
1. Loosen the four nuts which hold the vacuum pump
mount in place.
2. Turn the adjusting bolts until the proper belt tension
is achieved (1/2” deflection in the center of the belt,
halfway between the pulleys).
NOTE: When adjusting belt tension, make certain
that the engine shaft and vacuum pump shaft remain
parallel, and the belt tension is equal throughout the
belt width.
3. After adjusting, re-tighten the four nuts which hold
the vacuum pump mount in position. Check belt
alignment with straight-edge.

NOTE: If the float ball has any water inside it must be
replaced.
When replacing float ball, DO NOT over- tighten, as
the rod can puncture the ball. Make sure to tighten
the nuts on the rod.
Waste Tank Strainer Basket
The strainer basket located inside the waste tank
should be removed and cleaned whenever it is full of
debris. This should be done on at the end of each job.
Waste Tank Vacuum Inlet Filter
The Vacuum Inlet Filter located inside the waste tank
should be removed, cleaned and inspected at the
beginning of each day. When replacing in tank ensure
that flow indicating arrow is pointing down.
2. Disassemble the valve and check the piston and
seat for damage, replace if needed. See the “Illustrated Parts Listing” for a parts break-down.
Waste Tank Float Valve
The float valve in the waste tank shuts the unit down
once the waste tank becomes full. Debris can collect
around the hinge of the float valve. Check the float
valve for debris at least once a month.
Solution
Inspect the solution screen after the first week of
running the unit by unscrewing the screen and remove
any accumulated debris. Inspect the screen again at 2

General Service Adjustments
USE EXTREME CAUTION while servicing while
machine is running. The high-speed mechanical
parts as well as high temperature components may
result in severe injury, severed limbs, or fatality.
Engine Speed
This unit uses a factory installed engine governor. The
engine speed is adjusted by pulling the throttle out to
maximum travel for high speed operation. For lower
temperature or vacuum setting, rotate knob clockwise
two turns or as needed to obtain desired temperature
and vacuum settings. Pushed in, the engine is at idle
speed (1400 rpm). With throttle pulled out, engine
operates at maximum rpm (2950).
DO NOT attempt to adjust without a tachometer and
NEVER adjust the engine to exceed stated maximum
RPM (Full Load). Permanent damage may occur.
Check Valve (Solution Outlet)
Inspect the check valve whenever doing service on the
chemical pump or if flow problems occur in the
chemical system:
1. Remove the check valve. Be sure the small o-ring
for the seat comes out with the check valve.
4. Clean the poppet and spring, inspect for wear or
damage, and replace as needed.
5. Re-assemble the check valve. Start the seat by
hand, tighten using a 5/16" Allen wrench. DO NOT
over-tighten seat.
NOTE:
Improper seating of the check valve poppet,
damaged spring or o-rings will cause poor operation
of the chemical system.
6. Lubricate the o-rings with o-ring lubricant Part
#86255430, PRV NO. 05-008035 and reinstall.
Water Box
1. Check inlet strainer for debris and blockage. A
blocked strainer could damage the solution pump if
water flow is restricted.
2. Inspect water box float valve for freedom of movement and water leaking past valve.
Chemical Pump
The only repairs which the chemical pump may require
are the replacement of the diaphragm, plastic disk or
check valves. To replace the diaphragm and plastic
disk unscrew the cover from the body. When replacing
the diaphragm, lubricate the outer edges of the
diaphragm with o-ring lubricant Part #86265430 and
reassemble. To replace the check valves, unscrew the
check valve caps. Replace the check valves and reassemble, using new o-rings.
DO NOT attempt to re-use o-rings once the check
valves have been removed. See the “Illustrated Parts
Listing” for a parts break-down on the chemical pump.
2. Remove the seat, using a 5/16" Allen wrench.
3. Check the Teflon seat for debris or wear. Clean or
replace Teflon seat if needed.

Packing Nut Adjustments for Chemical
Valves
Examine the packing nut on all chemical valves for
proper tension every 200 hours. When turning the
knob, there should be a small amount of resistance. If
not, slightly tighten the packing nut. DO NOT over
tighten. Keeping the valve packings properly adjusted
will eliminate possible leakage from the valve stem and
add to overall valve life.
Pressure Regulator
Maintenance
DO NOT loosen the adjusting body (cap) all the way
(counterclockwise) or remove it while the unit is
running.
We recommend that you lubricate the pressure
regulator o-ring every 50 hours, or whenever required.
If you do not, the stem may become seized due to inadequate lubrication. If this occurs:
a. Shutdown the unit.
b. Relieve all pressure from the water system.
c. Remove the cap from the pressure regulator and
remove the stem with long nose pliers.
d. Clean and lubricate stem.
e. Reassemble pressure regulator.
The pressure regulator serves to maintain water
pressure at a preset point and to bypass water back to
the water box.
To adjust:
1. With your unit running, close the cleaning tool
valve. Check the pressure gauge. Open the tool
valve. We recommend setting the pressure regulator so that the pressure gauge reads 450 PSI with
the tool valve open.
When the tool valve is opened, there is an approximate drop of 50 PSI in pressure. If there is a pressure drop greater than 100 PSI, it may be
necessary to lubricate the o-ring in the pressure
regulator.
2. If the pressure regulator requires adjustment,
loosen the locking nut, then turn the adjusting body
(cap) (while observing the pressure gauge on the
control panel) until the desired pressure is
obtained. Retighten the locking nut.
