ASSEMBLY INSTRUCTIONS
STEP 1: Place machine in a con-
venient location providing ample
support, drainage and room for
maintenance. Remove pallet bolts
and remove pallet, then re-install
bolts to level machine by adjusting
(machine must be level).
STEP 3: Remove the hex head
screws from electrical access panel.
Note: bottom right screw will only
loosen; access panel is designed
to pivot on this screw. Once access
panel is rotated out of the way, at-
tach the electrical harness from
the pressure washer to the heating
module as follows:
a. Feed pressure washer wire
harness through the upper
wire hole located on the side
of the machine.
b. On the right side of the in-
coming power terminal block,
connect the black wire to line
L1, the red wire to line L2, and
the white wire to line L3.
c. Attach the green wire to the
ground terminal block.
CAUTION:Have qualified electri-
cian attach the proper supply
cord to the terminal labeled L1,
L2 and L3.
STEP 2: Place the cabinet on top
of the heat exchanger and attach
the small high pressure hose to the
fittings as shown.

STEP 4: Do not turn power on to equipment until the heating module is
filled with water, as severe damage may occur to heater elements.
Prior to shipping, a rust inhibitor powder was added to the hot water
tank. This powder will mix with the added water to prevent rust build-
up inside the tank.
Install water fill spout (shipped loose). Spout opening should be fac-
ing up. Insert water hose and fill. Do not over fill to allow for thermal
expansion. (Maximum is 80 gallons). After heater tank has been filled
to the top, operate for one week and then add one quart of oil to slow
evaporation. Be sure to replace spout plug, hand tight only.
Turn on main power supply to unit. Set 7 day programmable timer
to desired ON/OFF time and switch machine power on, Water will
heat up to operating temperature in 30 to 60 minutes. The heater will
turn off automatically when 200°F is reached. Water will come out of
heater fill spout due to heat expansion. However, this will stop after
temperature is reached.
Leave main power on to the machine to ensure hot water on pump
start up.

PRECAUCION/AVERTISSEMENT
WARNING
WARNING: Some detergents
may be harmful if inhaled or
ingested, causing severe nau-
sea, fainting or poisoning. The
harmful elements may cause
property damage or severe
injury.
STEP 1: Use detergent designed
specifically for pressure washers.
Household detergents could dam-
age the pump. Prepare detergent
solution as required by the man-
ufacturer. Fill a container with
pressure washer detergent. Place
the filter end of detergent suc-
tion tube into the detergent con-
tainer.
STEP 2: Apply safety latch
to spray gun trigger. Open
variable pressure wand
handle to low pressure
which allows water through
black detergent nozzle.
NOTE: Detergent cannot
be applied during high pres-
sure.
STEP 3: With the motor running, pull trigger to operate
machine. Liquid detergent is drawn into the machine
and mixed with water. Apply detergent to work area.
Do not allow detergent to dry on surface.
IMPORTANT:You must flush the detergent injection
system after each use by placing the suction tube
into a bucket of clean water, then run the pressure
washer in low pressure for 1-2 minutes.
THERMAL PUMP PROTECTION
If you run your pressure washer for 3-5 minutes without
pressing the trigger on the spray gun, circulating water
in the pump can reach high temperatures. When the
water reaches this temperature, the pump protector
engages and cools the pump by discharging the warm
water onto the ground. This thermal device prevents
internal damage to the pump.
CLEANING TIPS
Pre-rinse cleaning surface with fresh water. Place
detergent suction tube directly into cleaning solution
and apply to surface at low pressure (for best results,
limit your work area to sections approximately 6 feet
square and always apply detergent from bottom to top).
Allow detergent to remain on surface 1-3 minutes. Do
not allow detergent to dry on surface. If surface appears
to be drying, simply wet down surface with fresh water.
If needed, use brush to remove stubborn dirt. Rinse at
high pressure from top to bottom in an even sweeping
motion keeping the spray nozzle approximately 1 foot
from cleaning surface. Use overlapping strokes as you
clean and rinse any surface. For best surface cleaning
action spray at a slight angle.
Recommendations:
Before cleaning any surface, an inconspicuous
area should be cleaned to test spray pattern and
distance for maximum cleaning results.

CAUTION
Pump Storage
CAUTION: Always store your pres-
sure washer in a location where the
temperature will not fall below 32° F
(0° C). The pump in this machine is
susceptible to permanent damage
if frozen.
FREEZE DAMAGE IS NOT COVERED BY
WARRANTY.
If you must store your pressure washer in a location
where the temperature is below 32° F, you can minimize
the chance of damage to your machine by draining your
machine as follows:
1. Stop the pressure washer and detach supply hose
and high pressure hose. Squeeze the trigger of the
spray gun to drain all water from the wand and
hose.
2. Restart pressure washer and let it run briefly (about
5 seconds) until water no longer discharges from
the high pressure outlet.

MAINTENANCE
Daily:
To ensure a problem free system, simple visual checks
can be performed. Check for leaks in inlet supply,
pumping system, pump to heater hose, heater, spray
gun(s) and high pressure hose. Check for normal op-
erating functions and pump oil level/condition. Check
nozzle condition. If badly worn or leaking conditions
are found, qualified personnel should repair or replace
components with new original or equivalent manufac-
turers parts.
Check equipment for proper operation. Nozzle spray
should be uniform in flow, angle, and pressure. Clean
if nozzle is plugged and replace if worn. If a heavy
pulsation in the hose or spray is observed, repair of
the pumping system is required.
Weekly:

ates a vapor barrier and slows evaporation of water
in the tank.
Check heat exchanger water level.The level must be up
to the filler pipe neck. Add water if necessary. If cold wa-
ter has been added, heating may cause the expanding
water to escape through the filler plug. This will stop
after operating temperature has been reached.
Monthly:
Check system for operation. Automatic start/stop, hot
high pressure water, and smooth operation should be
noted.
Change oil in pump crankcase. Note the condition of
the oil when drained. If found to be creamy, water seals
in pump may have to be removed and replaced.

Cold water added to heat exchanger Will stop once at operating tempera-
ture.
Ruptured coil or leaking Check, repair or replace fittings.
UNLOADER DOES NOT
GO INTO BYPASS OR

Spray gun or hose is leaking to
atmosphere
Check and repair all leaks.
Check plunger either did not move
or did not seal
Remove discharge port. Clean and
inspect the check plunger. Replace the
o-ring if needed.
Actuator o-ring failure Remove actuator plunger assembly
and inspect o-ring and back-up rings.
Replace if necessary.
SPIKES TOO HIGH Slow moving actuator; this may be
caused by bad o-rings either on the
plunger or inside the actuator fitting.
Remove the actuator assembly to
inspect the o-ring and back-up rings.
The actuator assembly will have to be
disassembled to inspect and/or replace
the o-rings in the actuator fitting.
Spring tension Adjustment should stop when pressure
is no longer affected by further com-
pression of the spring.
Hose length Hose length can affect the amount of
spike pressure. Long lengths of hose
may cause high spike pressures.
SYSTEM WON’T COME

Disassemble inlet fitting and check for
contaminates or worn parts. Clean or

O-Rings on actuator plunger are
bad
Remove actuator assembly and in-

place if necessary.
Locknut may be improperly set Readjust locknut.
NOTE: The locknut is inside the spring
on models that have the stem exposed
above the spring.
Tip/GPM combination is incorrect Check actual GPM on unrestricted

than expected with a worn tip
Replace tip.
Bad gauge - the pressure may be
higher than the gauge shows
Replace gauge.
