IMPORTANT!

When setting up

for new types of

refrigerant, a

clearing process

will have to be

performed.

ADDING REFRIGERANT TO THE TANK

CAUTION! R-134a systems have special fittings (per SAE

specifications) to avoid cross-contamination with other refrigerant

systems. Read and follow all warnings given at the beginning of this

manual.

NOTE: Purchase only tanks of R-134a refrigerant that have 1/2 inch (1.2cm)

Acme threads. This is necessary to match the hose adapter.

1. Connect the 96-inch (244 cm) blue low side hose to the unit's low-side port.

NOTE: Disposable tanks have only one valve and most must be turned upside down

to transfer liquid. If you are using a disposable tank, follow the instructions on the

side of the tank to obtain a liquid supply.

2. When using R-12 connect the 6-inch (15.2-cm) yellow adapter to

the source tank liquid valve first. Then connect the 96-inch (244-cm) blue low-

side hose to the adapter.

When using R-134a, connect the low-side connector port adapter to the

source tank liquid valve first. Then connect the blue 96-inch (244-cm) low-

side hose directly to the adapter.

3. Open the LIQUID valve on the source tank (there is only one valve on a

non-refillable tank.)

4. Close the high-side manifold valve and open the low-side manifold valve on

the front panel of the unit. Open both valves on the unit tank.

5. Press SHIFT/RESET and ENTER at the same time to access the diagnostic

mode. The display shows the message "FUNC."

6. Press 2 to begin transferring refrigerant. The display shows the “Add”

message for about two seconds, then shows the amount of refrigerant transferred.

7. Transfer stops automatically and the display shows the “CPL” message when the

source tank is empty and has been pulled to a partial vacuum or the weight of

refrigerant in the unit tank reaches 37 pounds. The display toggles between

“CPL” and the weight in the tank
