NITROGEN ACCUMULATOR
The nitrogen accumulator is pressurized to 250 PSI
and must be replaced periodically. The accumulator
cannot be repaired or recharged. We recommend
replacement every 1000 hours of use or yearly,
whichever comes first.
PRESSURE REGULATOR
Lubricate the o-rings every 50 hours. Use o-ring
lubricant Part #05-008035.
For the procedure, see the "General Service
Adjustments" section in this manual for details.
VACUUM HOSES
To assure maximum hose life, we recommend that
the hoses be washed out with clean water at the end
of each working day.
PRESSURE HOSES
Inspect your pressure hoses for wear after
the first 100 hours of use. Inspect every 25 hours
thereafter. If hoses show any signs of damage or
impending rupture, replace the hose.
DO NOT attempt to repair pressure hoses!
Repairing pressure hoses may result in severe
burns and serious injury!
All pressure hoses must be rated for 3000 PSI at
250°F. Thermoplastic hoses do not meet these
specifications and should not be used.
OPTIONAL WASTE PUMP-OUT
At the end of each work day, make certain that you
remove any debris or sediment which may be inside
the waste pump by pumping fresh water through the
pump.
CHEMICAL AND
SIMULATOR VALVE
Examine the packing nut on the chemical prime
selector valve, flow simulator valve, and chemical
metering valve every 200 hours.
Keeping these valve packings properly adjusted will
eliminate possible leakage from the valve stems and
add to overall valve life.
For the procedure, see the "General Service
Adjustments" section in this manual for details.
ENGINE COOLANT REPLACEMENT
Annually the coolant in the Prochem machine should
be replaced. This coolant is an integral part of the
heating system and needs to be maintained as any
other working part of the system. We recommend
that this procedure be accomplished by the following
steps.
DRAINING COOLANT:
1. Add 7/16" hose or a 1/4" plastic hose into the
NOTE: Be sure that used coolant is collected in a
proper container and disposed of in accordance
with local laws.
2. After draining is complete, close both the
