Storage & Maintenance Instructions

SPECIFIC MAINTENANCE

PUMP: Change the pump oil after the first 50 hours of operation. After 

initial change, every 3 months or 250 hour intervals are recommended. 
If oil appears dirty or milky, changes may be required in greater 
frequency. Use pump oil SAE20 or 30 and fill only to the center of the 
oil sight glass. DO NOT overfill.

QUICK COUPLERS: There are o-ring seals inside the couplers which 

will deteriorate. To replace, simply install a replacement o-ring to 
correct the leak. (Additional o-rings can be purchased from your 
dealer.)

NOZZLE: Water flow through the spray nozzle will erode the orifice, 

making it larger, resulting in a pressure loss. Nozzles should be 
replaced whenever pressure is less than 85% of the maximum. The 
frequency of replacement will depend upon such variables as mineral 
content in the water and number of hours the nozzle is used.

BURNER AIR ADJUSTMENT: The air shutter has been factory preset 

for proper operation between sea level and 2000 feet elevation at 
standard conditions (60°F ambient water and air temperatures). To 
assure maximum combustion efficiency at colder temperatures and 
higher altitudes, it will be necessary to adjust the air supply to the 
combustion chamber. A smoke spot test is recommended during any 
air shutter adjustment. This will aid in maximizing the burner efficiency 
and avoid the inefficient operation and excessive sooting of the 
combustion chamber.

1. The machine must be running and the burner on.

2. Take a smoke spot test to determine if more or less air is required for 

proper combustion.

a. If the test is greater than a #3 smoke, turn the shutter arm 
counterclockwise to increase the air flow into the combustion 
chamber.
b. If the test is yellowish in color, turn the shutter arm clockwise to 
decrease the air flow into the combustion chamber.

3. Hold onto the air shutter adjusting arm and loosen the locking nut. 
Move the shutter in 1/8” increments and retighten the locking nut after 
each 1/8” movement.

4. Trigger the gun on and off slowly to make sure there is proper ignition. 
Slight or no puffing on the ignition, and a smoke spot test of 0-3 is 
good.

5. Repeat steps 2 and 3 until step 4 is attained.

WINTERIZING

1. For storage and transportation purposes in subfreezing ambient tem-

peratures, it will be necessary to winterize this unit. This unit must be 
protected to the lowest incurred temperature for the following reasons:
a. If any part of the pumping system becomes frozen; excessive 
pressure may build up in the unit which could cause the unit to burst 
resulting in possible serious injury to the operator or bystanders.
b. The pumping system in this unit may be permanently damaged if 
frozen. FREEZE DAMAGE IS NOT COVERED BY WARRANTY.

If you must store your unit in an area where the temperature may fall 
below 32°F, you can protect your unit by following the procedure outlined 
below.

1. Gather the following items:

a. Two 5 gallon containers.
b. One gallon of antifreeze. (Use an environmentally safe antifreeze.)
c. Water supply.
d. Three foot hose, 1/2-3/4 I.D. with a 3/4 inch male garden hose fit­ting.

2. Procedure:

a. To start winterizing, unit must be run according to the “Start-up 
Cold Water Operation”.
b. After running, shut off the unit and water supply.
c. Relieve system pressure by pointing the trigger gun in a safe direc­tion and squeezing the trigger until water flow ceases to exit the Lance 
Assy. 
d. Lock the trigger gun in the OFF position and adjust the Lance to the 
low pressure mode.
e. Remove the water supply hose from the unit and attach the 3 foot 
hose securely to the inlet connection.
f. Shut off the detergent injector (if applicable).
g. Fill one 5 gallon container with water.
h. Holding the 3 foot hose in an upright position, completely fill the 
hose with water. Then plug the open end of the hose with your thumb 
or finger. Place the plugged end into the 5 gallon container of water.
i. Start the unit. Trigger the gun several times until all the air is worked 
out of the system (unit is primed).

j. With the trigger gun held open, siphon enough water out of the 5 
gallon container until there is just enough water left to mix with the 
antifreeze.
k. Point the trigger gun into the empty container. (Be certain to wear 
safety attire for protection from splashing.)
l. Trigger the gun until the antifreeze begins to exit the trigger gun. 
Release the trigger for 3 seconds, then trigger the gun for 3 seconds. 
Continue cycling the trigger gun several times until all the antifreeze 
mixture is siphoned from the container.
m. Stop the unit.
n. Detach the 3 foot hose from the unit and drain any excess antifreeze 
back into the 5 gallon container storage & maintenance
o. Disconnect the hose and trigger gun from the unit and drain any 
excess antifreeze back into the 5 gallon container.
p. Drain hose, trigger gun and lance assembly and store with the unit 
in a safe non-freezing area.
q. Store antifreeze solution for next use or dispose of according to 
state EPA laws.

3. OPTIONAL PROCEDURE:
a. Shut the unit and water supply off.
b. Relieve system pressure by pointing the trigger gun in a safe 
direction and squeezing the trigger until water flow ceases to exit the 
nozzle.
c. Disconnect and drain the hose, trigger gun and lance assembly.
d. Remove the coil drain plug from the heat exchanger inlet.
e. Start the unit and allow it to run until all the water exits the unit. 
Once the water has stopped flowing from the unit, turn off.

NOTICE

When using this procedure, use caution as ice chips can form from
drops of water which could cause the unit to burst if starting before
completely thawed.

NOTICE

Proper winterizing is based on the recommended manufacturer’s 
instructions listed on the “Protection Chart” shown on the back label of 
most antifreeze containers.

d. Remove the coil drain plug from the heat exchanger inlet.
e. Start the unit and allow it to run until all the water exits the unit. Once

the water has stopped owing from the unit, turn off.

NOTE: When using this procedure, use caution as ice chips can form from

drops of water which could cause the unit to burst if starting before
completely thawed.

WATER FLOW: Connect a pressurized water source to the inlet GAR­DEN HOSE CONNECTION (1) and turn on the water supply.

The water then travels into the TRIPLEX HIGH PRESSURE PUMP (2) 
which has an UNLOADER (3) that bypasses the water when the trigger 
gun is closed. To protect the pump from heated water during this bypass 
stage, a HEAT DUMP VALVE (4) will open at 140°f/60°c allowing the 
heated water to escape. The heat dump valve automatically resets when 
the water cools. The PRESSURE SWITCH (5) controls the fuel supply to 
the burner.

From there, the water will flow into the HEAT EXCHANGER INLET (8) 
where it is heated when the burner is on. As the water exits the HEAT EX­CHANGER OUTLET (9), it enters a safety system which protects the op­erator from danger. The safety system contains a HIGH TEMPERATURE 
LIMIT SWITCH (16) which senses the water temperature and shuts off 
the fuel supply to the burner if it gets too hot. If the unloader fails to by­pass the water or the burner remains on when the trigger gun is closed, 
the SAFETY RELIEF (14) will relieve and allow water to exit safely.

The heated water then flows through the HIGH PRESSURE HOSE (13) 
and to the TRIGGER GUN ASSEMBLY (12) which allows the operator 
to control the water spray. When the trigger gun is open, the water flows 
through the LANCE (11) and exits the NOZZLE (10).

FUEL FLOW: The fuel pump draws fuel from the FUEL TANK (19) 
through a replaceable FUEL FILTER (18) and into the FUEL PUMP (17). 
Fuel exits the fuel pump, into a FUEL SOLENOID VALVE (6) which con­trols fuel flow to the FUEL NOZZLE (7) where it ignites and burns in the 
heat exchanger.
