Dual Voltage Motor Power Conversion (if applicable)
*Warranty is void if the set vacuum pump voltage does not match the power supply. Dual voltage
motors are factory set to 230V/50Hz.
8) Use a SuperEvac System I, II or
III to decrease
vacuum time by
over 50%. These
systems include
a 2-valve
vacuum mani-
fold and two
3/8” vacuum hoses which can
evacuate three times faster than a
1/4” hose.
9) Use a heat gun ot the condenser
and evaporator to speed the evacua-
tion process.
Built-in vacuum gauge:
The unique
built-in indicator gauge in
you pump monitors
evacuation progress
down to the 29-30”
range. If the reading stays
in the mid range, there is
either high contamination
or a large leak in the system.
If you think there is excessive moisture,
blow out the AC&R system with dry
nitrogen wherever possible. This reduces
the amount of contaminants that must be
“pulled” into the pump and increases
evacuation speed.
Use a nitrogen regulator
valve with pressure
limited to 150 psi, and a
frangible disc device set
at 175 PSIG.
When the indicator
reaches the 29-30” range,
turn on the electronic micron gauge for
more precise readings.
Oil Changes:
CHANGE OIL
AFTER EACH USAGE
to protect
pump components from contaminants
pulled into pump during service. Place
used oil in a sealable container and
dispose properly in accordance with
local regulations.
STEP 1
Disconnect the
motor from the
power supply
and remove.
Remove the
yellow “CAU-
TION” sticker
from the back of
the motor.
STEP 2
Pull up on the white plastic “arrow”
switch using needle-nosed pliers until
the switch is
loose inside the
motor housing (it
will not come
completely out of
the motor).
Note: Do not try
to turn or rotate
the switch until it has been pulled up and
is loose.
STEP 3
Point the arrow toward the desired
voltage setting and push the switch back
down into the
motor. The arrow
on the switch
should be sub-flush
of the motor
housing when
correctly installed
at the desired
voltage.
HI = 230 VAC / 50 Hz
LO = 115 VAC / 60 Hz
STEP 4
Replace the yellow
“CAUTION” sticker
over the voltage
selector switch.
Ensure that the
voltage setting
corresponds with the power supply that
the motor is plugged into.
