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.
Be sure to use the correct hose set for the refrigerant type selected:
5. Turn on the MAIN POWER. Press SHIFT/RESET, then press RECOVER.
Transfer stops automatically and the display shows "CPL" when the source tank
is empty and has been pulled to 13 inches of vacuum. The display toggles
between "CPL" and the weight in the tank. You can interrupt this at any time by
pressing HOLD/CONT once. Press HOLD/CONT again to resume operation.
