STEP 1

Disconnect the 

motor from the 

power supply 

and remove. 

Remove the yellow 

“CAUTION” 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.

If you think there is excessive mois-

ture, 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 pres-

sure limited to 150 psi and a frangible 
disc device set at 175 PSIG.

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 accor-

dance with local regulations.

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.

8. Use a SuperEvac

 System I or II to

decrease vacuum

time by over 50%.

These systems

include a 2-valve

vacuum manifold

and two 3/8”

vacuum hoses which can evacuate

three times faster than a 1/4” hose.

9. Use a heat gun on the condenser and

evaporator to speed the evacuation

process.

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.
