A.
Check that all inlet line connections are tight and properly sealed.
B.
Ensure that the suction connection in the reservoir is not adjacent to or near to
any oil return connection which could cause oil foaming.
C.
With a ¾” wrench, exercise the inlet and outlet pressure control valves. There
may be a piece of trash stuck in one of these valves that is causing the valve to
chatter. After exercising the valves and the trash has been removed, reset the valve
to its previous position by ensuring that all the operating pressures are back to the
normal values. Exercising these two valves will change the pressure in which the
unit is running.
High/ low filter
discharge
pressure
If filter discharge pressure range is too high, replace filter element.
(
Replace filter element at maximum 30 PSIG (2 bar) differential
)
If filter discharge pressure range is too low with a clean filter, reset pressure relief
safety valve (PRV1) by turning off machine for 15 seconds and allow the pop-off
valve to reseat. Restart the machine and check pressure settings. Adjust PCV1 if
necessary.
Outlet
Pressure
The normal outlet pump discharge pressure range should be 3.4-608 BAR (50-100
PSIG).
If outlet pump discharge pressure range is too high
,
check the return line for
blockage.
If outlet pump discharge pressure range is too low, reset
PRV2
by turning off
machine for 15 seconds and allow the pop-off valve to reseat. Restart the machine
and check pressure settings.
NOTICE:
DO NOT adjust pressure setting in PRV1 & PRV2. Relief valves
are they are factory set at 290 PSIG.
In no case should the pressure be allowed to
exceed 300 PSIG. If such a high pressure is
indicated, immediately turn off the unit, and
take any necessary steps to pre-heat the oil.
Refer to shut down procedures. If this occurs
use the main shut off switch. This unit is
equipped with a two- (2) minute time delay for
cooling down the oil heater during a normal
shutdown.
