STEP 1: Connect the downstream chemical injector to
the high pressure outlet. Route the soap line into the
left fuel cabinet and into detergent bucket. (buckets not
provided).
HEAT EXCHANGER:
The incoming water temperature is raised for bet-
ter burner efficiency by the use of the systems heat
exchanger. The heat exchanger is made up of three
stages, these stages are engine exhausts stage, mix-
ing stage and exit stage. The hot engine exhaust is
sent to the exchanger box where it passes thru the
heat transfer core. The preheated water is then sent to
the high pressure pump and exhaust gases then exit
the unit.
WARNING: The heat exchanger core
becomes extremely hot and should
not be touched while the machine is
in operation. Allow machine to cool
down completely before attempting
to service this area. Always wear
hearing protection and proper per-
sonal protection equipment when
operating unit
HEAT EXCHANGER SYSTEM MAINTENANCE:
The heat exchange system in your units transfers en-
ergy between the heat of the power plant to the water
supply of the unit. 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. The surface area amount is adversely minimized

STEP 2: Selection of high or low pressure is accompa-
nied by turning the handle.
NOTE: High pressure nozzle must be inserted at the
wand to obtain high pressure. Variable pressure con-
trol wand handle must be turned clockwise to enable
water to flow out of the high pressure nozzle.
To apply detergent, place detergent pick-up tube into
a container of detergent and turn the detergent valve
handle on the wand counterclockwise.
when the supplied water is not softened to recom-
mended levels (exceeds 3-1/2 grains). Hard water
will result in scaling on the inside walls of the heat
exchanger tubes. It is recommended that you use a
dealer-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 sensi-
tive to freezing conditions. The following is recom-
mended during the cold weather season.
When 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.
WARNING: When disposing of anti-freeze,
observe local laws and regulations. Do not
drain onto ground or into storm drainage
systems.
NOTE: Inspect and clean exchanger core and box ev-
ery 500 hours.
NOTE: The heat exchanger will produce water con-
densation discharge at times during normal operation.
DO NOT confuse this with a leak.
