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.
PRESSURE REGULATOR
Lubricate the o-rings every 50 hours. Use o-ring
lubricant Part #86265430, PRV NO. 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.
HIGH PRESSURE HOSES
Inspect your high 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 high pressure hoses!
Repairing high pressure hoses may result in
severe burns and serious injury!
All high pressure hoses must be rated for 3000
PSI at 250°F. Thermoplastic hoses do not meet
these specifications and should not be used.
Severe burns and injury may result if the hoses
do not meet these requirements.
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.
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. Reference Kohler Manual for specific coolant
draining instructions. Drains are located at the
bottom of the radiator and on the engine block
next to the oil filter.
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
radiator and heli-coil petcocks. Draining is
complete.
REPLACING COOLANT:
1. Fill radiator with 50/50 anti-freeze water mix.
2. Start unit and run on first notch.
3. As the unit warms up, maintain a full radiator
with a 50/50 mix.
4. Open petcock slightly on heli-coil to allow any
trapped air to escape. When coolant runs out of
heli-coil, close petcock.
5. Fill radiator with 50/50 coolant mix.
6. Re-install radiator cap.
7. Shutdown unit.
Check radiator overflow bottle. Add coolant to
proper “cold” level.
