In order to make the best use of your
investment, familiarize yourself with the
new features and operating instructions
before starting pump. With just routine
care your
FastVac
will give you years of
reliable service by following proper
maintenance guidelines.
FastVac
pumps
are designed for deep vacuum work in
refrigeration systems only.
IMPORTANT: Use oil specifically refined
for deep vacuum pumps. Using oil not
refined for deep vacuum pumps and/or
operating with contaminated oil will void
warranty.
Each
FastVac
pump has been factory
tested to guarantee 25 micron or better
and listed CFM performance. The serial
number has been recorded. Complete and
mail the Warranty Registration Card within
10 days of purchase to validate your
warranty. You will be notified of any
technical updates.

Slowly add oil until oil level rises to the

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°F. Line
voltage must be equal to motor
nameplate ±10%. Normal operating
temperature is approximately 160°F,
which is hot to the touch. Line voltage and
ambient conditions will affect this
somewhat. Motor has automatic resetting
thermal overload protection.
FastVac
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°.
Valve completely closed at 90°.
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
Crack gas ballast valve. Continue running
pump for 2-3 seconds. With valve still
cracked, stop pump. Close isolation valve
and gas ballast 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, FastVac 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
Both Gauges Feature
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
FastVac
Pump Oil. Replace oil fill cap.
FLUSHING
If the oil is badly contaminated, flushing may be
necessary. Slowly pour 1/3–1/2 cup of fresh
FastVac
oil into the intake connection while pump is running.
Repeat as required until contamination is removed
from oil reservoir, 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.
