placement:
Do not locate near any combustible material. Keep all
flammable material at least 20 feet away.
Allow enough space for servicing the machine.
Local code will require certain distances from floor and
walls. (Two feet away should be adequate.)
Water source:
Water source for machine should be supplied by a 5/8"
I.D. garden hose with a city water pressure of not less
than 30 psi. If the water supply is inadequate, or if the
garden hose is kinked, the machine will run very rough
and the burner will not fire.
Connection:
Connect the wand, nozzle, hose and spray gun (where
applicable). On pipe thread connections, use teflon
tape to avoid water leaks. (See Component Identifica-
tion.)
Attach high pressure hose to discharge nipple by pull-
ing the quick coupler collar back and inserting it onto
the discharge nipple. Then push the collar forward to
secure. A detergent injector could be inserted between
the hose coupler and the discharge nipple. (See page
10.)
Place detergent dip tube into liquid soap or detergent
solution. Avoid letting tube suck air.
CAUTION: When installing propane hose to LP tank,
please note that it has left hand threads.
Inspection and Testing:
Before turning gas under pressure into piping, all open-
ings from which gas can escape should be closed.
Immediately after turning on gas, the system should
be checked for leaks. This can be done by watching the
1/2 cubic foot test dial and allowing 5 minutes to show
any movement, or by soaping each pipe connection
and watching for bubbles. If a leak is found, make the
necessary repairs and repeat the above test.
Defective pipes or fittings should be replaced and not
repaired. Never use a flame or fire in any form to locate
gas leaks, use a soap solution.
After the piping and meter have been checked com-
pletely, purge the system of air.
Do noT bleed the air
inside an enclosed room.
The pressure washer and its individual shut-off valve
must be disconnected from the gas supply piping
system during the pressure testing of that system at
test pressure in excess of 1/2 psig or damage to the
gas valve will occur.
shut-off valve:
A gas shut-off valve has been installed between the gas
supply line and the washer. The plumbing also includes
a union between the shut-off valve and the burner.
Condensation from Coils:
When cold water is being pumped into the water heater
coils, and the burners are on, condensation will form on
the coils and drip down into the burner compartment
giving the appearance of a leaking coil, particularly on
cold humid days.
Check Water heater Coil for leaks:
With the burner “OFF” start the pumping machine and
allow to run for a few minutes. Look into the burner
compartment with a drop light or flashlight. If no leak
is visible, then subsequent water dripping from the coil
will be from condensation in the flue gases when the
burner is on, as described in the previous paragraph.
