DISCHARGE PIPING
It is recommended that the exhaust be piped horizontally a short distance and tied into a vertical exhaust pipe. The vertical exhaust
pipe must be at least 1 ft. long and the bottom end of the vertical exhaust pipe be terminated with a plug or drain valve to allow
removal of moisture and contaminated oil before it can accumulate sufficiently to drain back into the pump oil reservoir.
The exhaust pipe should be no smaller than the pump exhaust outlet and as short as possible. Run the pipe outside the building
or into a coalescing Oil mist filter. When pumping noxious or toxic gases, the exhaust must be vented outside the building even if a
discharge oil mist filter is installed.
The pump exhaust should have a horizontal run to a drop-out Tee, and then go up if necessary. Equip the Tee with a drain valve to
drain off condensate from time to time as needed. Oil mist eliminator filters are available to replace the piping.
When starting the pump or handling large amounts of air, oil vapor in the form of smoke will exit the pump exhaust port. This is no
indication of trouble, as the volume of smoke will decrease as the volume of air reduces and the vacuum in the system improves.
OIL EXHAUST FILTERS are available to alleviate exhaust smoke.
ELECTRICAL CONNECTIONS
A schematic diagram for the electric motor terminal box is located either inside the junction box cover or on the side of the motor itself.
The motor must be connected according to applicable electrical codes Through a fused switch in order to protect the motor against
electrical or mechanical overload conditions. The overload of the motor starter must be set at a level equal to the full load motor
current listed on the nameplate.
Wire the solenoid valve to allow oil flow from the pump oil reservoir to the pump bearings & internals.
AFTER ELECRICAL CONNECTIONS HAVE BEEN MADE, BUT PRIOR TO FILLING THE PUMP WITH OIL, THE ROTATION OF
THE MOTOR SHOULD BE CHECKED. IF BACKWARD, REVERSE ANY TWO LEADS OF THE THREE AT THE POWER
CONNECTION.
OIL FILLING
The successful operation of this pump depends largely on the type of oil used. An initial charge of oil is included with each pump. This
standard oil is US350-H which is recommended for general operating in a relatively clean environment.
After level installation and correct rotation of the pump has been established, fill the pump with recommended oil through the oil fill
port. Oil level should be at the 3/4 position on the sight glass window.
Oil capacity: RP-50B = 4 Gallons
CHANGE OIL EVERY 500-750 OPERATING HOURS
Check the oil for contamination on a weekly basis by shutting the pump off and draining some of the oil into a small
glass or container through the oil drain port.
Oil life is dependent upon the condition to which it is exposed. The oil must be changes after the first 100 hours of initial
operation. After the initial oil change, and when using US350-H, it is recommended that the oil changes are made every
three (3) or four (4) months or 500-750 hours of operation, or as necessary if high heat is contaminating the oil.
To change the pump oil, the pump must be switched off and ventilated to reach atmospheric pressure. Open the oil
drain valve and drain the oil. Dispose of the oil in compliance with local or national
regulations. When oil stops draining, replace the oil drain plug.
Start the pump again for a few seconds. Stop the pump once again, and then reopen the oil drain valve and discharge
any remaining oil. Refill with new oil. Optimum pump oil temp. should be between 140-160 Def F.
