Maintenance And Service
Unloader Valves
Unloader valves relieve pressure in the line when the
shut-off spray gun is closed. Unloader valves are
preset and tested at the factory before shipping. Occa-
sional adjustment of the unloader may be necessary to
maintain correct pressure. (Contact your local dealer
for correct procedure in adjusting unloader valve.)
Tampering with the factory setting may cause personal
injury and/or property damage, and will void the manu-
facturer's warranty.
Winterizing Procedure
Damage due to freezing is not covered by warranty.
Adhere to the following cold weather procedures
whenever the washer must be stored or operated
outdoors under freezing conditions.
During winter months, when temperatures drop below
32°F, protecting your machine against freezing is
necessary. Store the machine in a heated room. If this
is not possible then mix a 50/50 solution of anti-freeze/
water into a 5 gallon bucket and with a short section of
garden hose elevate the bucket and turn the pump on
to siphon the anti-freeze through the machine. If
compressed air is available, an air fitting can be
screwed into the inlet connector and, by injecting
compressed air, all water will be blown out of the
system.
High Limit Hot Water Thermostat
For safety, each machine is equipped with a high limit
control switch. In the event the temperature of the water
should exceed its operating temperature, the high limit
control will turn the burner off until the water cools.
Pumps
Use only SAE 10W-40 weight non-foaming oil. Change
oil after first 50 hours of use. Thereafter, change oil
every year or at 500 hour intervals. Oil level should be
checked through use of the dipstick found on the top of
the pump or by the red dot visible through the oil gauge
window. Oil should be maintained at that level.

Cleaning of Coils
In alkaline water areas, lime deposits can accumulate
rapidly inside the coil pipes. This growth is increased by
the extreme heat build up in the coil. The best preven-
tion for liming conditions is to use high quality cleaning
detergents. In areas where alkaline water is an extreme
problem, periodic use of Coil Descaler (part #8.914-
296.0) will remove lime and other deposits before coil
becomes plugged.
Periodic descaling of the heating coil is recom-
mended so please consult your local Dealer for
instructions.
Removal of Soot and Heating Coil
In the heating process, fuel residue in the form of soot
deposits may develop between the heating coil pipe
and block air flow which will affect burner combustion.
When soot has been detected on visual observation,
the soot on the coil must be washed off after following
the coil removal steps.
1. Remove the tank head assembly by unscrewing
the three Tek screws and lifting the tank head off.
2. Remove the two pipe nipples and associated
fittings.
3. Lift the coil out of the outer wrap.
CAUTION: The coil weighs about 80 lbs. Use proper
lifting techniques.
ATTENTION: La bobine pèse environ 36.2874 kg (80
lb). Utiliser des techniques de levage appropriées.
4. Clean, repair and replace the coil by reversing the
bove steps.
