USING THE HEATER BLANKET
A heater blanket speeds the transfer of
refrigerant and assures a complete
charge by raising the pressure within the
refrigerant tank.
1. Wrap the heater blanket around the
refrigerant tank, secure it with the
Velcro
® strap, and plug its power cord
into the heater outlet on the bottom
of the control box (right receptacle).
2. Turn on the MAIN POWER switch
on the front of the station.
The heater blanket is on whenever the
station’s MAIN POWER switch is on,
eliminating the need for manual control.
You can extend the life of the heater
blanket by unplugging the heater when
it’s not being used or turning off the
MAIN POWER switch.
•Refillable tanks — Leave the tank
upright, attach the yellow charging
hose to the blue LIQUID valve on the
tank, and open the blue valve.

charging hose (the open position runs
parallel to the hose).
Note: Use a maximum tank size of 50
pounds (23 kilograms) with this charging

3. Fasten the tank securely with the
tank hold-down bracket. Place the
heater blanket around the center of
the tank, and fasten it securely (see
“Using the Heater Blanket”).
4. Secure the retaining strap around
the tank.
Note: Adjust the strap so that it comes in
contact with the tank, but is not tight
around the tank .

ing the HOLD key to interrupt the

CYCLE key, depending on the
