warning instructions may result
in personal injury or property
damage.
2. Turn all switches off.
3. Review installation instructions.
4. Connect the water supply hose to the inlet connec-
tor and turn the water on. Check for water leaks and
tighten as needed.
5. Have an electrician connect power supply into junc-
tion box according to information shown on the se-
rial plate.
6. Turn on the main gas supply.
7. Partially depress and turn control knob to the “OFF”

cumulated in the main burner compartment, to es-
cape.

10. Depress the control knob all the way and hold it in.
After five (5) seconds, depress the red ignitor until
you hear a loud click. Repeat 3 or 4 times if neces-
sary until pilot is lit. If pilot does not remain lit, repeat
the operation allowing a longer period of time before
releasing the gas valve knob. After the pilot lights,
continue to hold the control knob down for about one
(1) minute before releasing.
NOTE
: Sufficient time must be allowed for a proper
size pilot flame to heat the thermocouple and hold
the safety magnet in a locked-up position. Also, time
must be allowed for air to escape from the lines dur-
ing the first operation.
11. Release dial and turn to full "ON".
12. Attach the desired high pressure nozzle into the wand
quick coupler by pulling the coupler collar back and
then inserting the nozzle and securing it by pushing
the coupler collar forward.
13. Push "ON" switch, or turn to pump position and pull
the trigger on the spray gun allowing cold water to
flow.

To Stop:
Turn the burner switch "OFF" and place
the detergent pick up tube into fresh water. Open
the detergent valve and spray gun allowing deter-
gent lines to be flushed and the burner to cool. Oth-
erwise coil damage will result.
17. After water has cooled, push or turn pump switch to
OFF position. If the machine is going to be off for an
extended period of time, put the gas cock dial on the
gas valve into the “OFF” position.
18. Turn water off. Prevent from freezing.
PREVENTATIVE
MAINTENANCE
1. Check to see that the water pump is properly lubri-
cated.
2. Follow winterizing instructions to prevent freeze dam-
age to the pump and coils.
3. Always neutralize and flush detergent from system
after use.
4. If water is known to be high in mineral content, use a
water softener in your water system or descale as
needed.
5. Do not allow acidic, caustic or abrasive fluids to be
pumped through system.
6. Always use high grade quality Shark cleaning
products.
7. Never run pump dry for extended periods of time.
8. Periodically delime coils as per instructions.
It is advisable, periodically, to visually inspect the burner.
Check air inlet to make sure it is not clogged or blocked.
Wipe off any oil spills and keep this equipment
clean
and dry
.
The areas around the Shark washer should be kept clean
and free of combustible materials, gasoline and other
flammable vapors and liquids.
The flow of combustion and ventilating air to the burner
must not be blocked or obstructed in any manner.
GENERAL WASHING
TECHNIQUES
If dirt comes off relatively easy and no grease and oil are
present, cleaning with cold water will normally suffice.
However, when grease and oil are present, hot water
will greatly speed up the process.
Clean with the spray nozzle a foot or so from the surface
being cleaned. For more difficult cleaning, move the
nozzle in closer.
