Forming Water and Corrosive Acids.
Drain Immediately While Pump Is Warm.

Slowly add oil until oil level rises to the
top of OIL LEVEL line. Replace oil fill

If oil is too low, you will hear the exhaust
baffle chatter. If the oil level is too high,

OPERATION
PUMP MOTOR
Pump and oil must be above 30 oF. Line
voltage must be equal to motor
nameplate p10%. Normal operating
temperature is approximately 160oF,
which is hot to the touch. Line voltage and
ambient conditions will affect this
somewhat. Motor has automatic resetting
thermal overload protection.
Platinum
is
designed for continuous duty and will run
for extended periods without overheating.
Quarter-turn on/off. No additional valve
needed to isolate system.
When checking pressure rise, slowly turn
handle counter-clockwise. Pause at 45 o.
Valve completely closed at 90 o.
START-UP
Open one intake port and isolation valve,
close gas ballast valve and start pump.
Make vacuum connections.
Crack gas ballast valve for the first part of
the evacuation procedure. After pump
quiets down from initial volume of air,
close valve and continue evacuating.
Failure to close valve will result in poor
pump performance.
SHUT-DOWN
Close isolation valve and crack gas
ballast valve. Continue running pump for
2-3 seconds. With gas ballast valve still
cracked, stop pump and then close valve.
Remove hose connections and cap
intakes.
IMPORTANT
DO NOT START PUMP BEFORE ADDING OIL
The following procedures will prevent oil from being drawn
into cartridge and creating hard start-up.
CHANGING OIL
To reach deep vacuum, Platinum pumps need
clean, moisture-free oil throughout evacuation.
Care should be taken to avoid contact on skin and clothing when changing oil.
Used oil should be disposed of in a leakproof corrosive-resistant container.
Pump oil should be changed after each
use. If system is heavily contaminated, oil
may have to be changed several times
during evacuation.
ISOLATION
(BLANK-OFF) VALVE
1. After every evacuation while pump is warm and oil is thin, place
pump on level surface and open oil drain. Oil can be forced from
the pump by opening one intake and partially blocking the
exhaust with a cloth while the pump is running. Do not operate
the pump for more than 20 seconds using this method.
2. Close drain. Remove oil fill cap and fill to top of OIL LEVEL line
with
Black Gold
Pump Oil. Replace oil fill cap.
FLUSHING
If the oil is badly contaminated, flushing may be
necessary. Slowly
Black Gold
oil into the intake connection while pump is running.
Repeat as required until contamination is removed from oil resevoir, pump
rotors, vanes and housing.
Dispose of all oil used in flushing of pump.
Being just a teaspoon
low affects the ultimate
vacuum.
excess oil will be blown out the exhaust.
