MAINTENANCE - GAS
APEX 86037630 4-8
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 – PV 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.
TEMPERATURE BALANCE ORIFICE
Weekly maintenance of the temperature balance
orifice is required for proper machine operation.
1. Unscrew nozzle cap from the connector body.
2. Remove the adapter, orifice plate, and strainer.
3. Clean any debris from the strainer and orifice
plate.
4. Reassemble as shown in Parts Section - Solution
Outlet.
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
radiator drain petcock. Turn counter clockwise
to open and drain coolant. After draining
approximately 1/2 gallon, open bleed petcock in
heli-coil to assure that heli-coil drains also.
Allow the coolant to completely drain.
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 70/30 anti-freeze water mix.
2. Start unit and run on first notch.
3. As the unit warms up, maintain a full radiator
with a 70/30 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 70/30 coolant mix.
6. Re-install radiator cap.
7. Shutdown unit.
Check radiator overflow bottle. Add coolant to
proper “cold” level.
