7. Attach the high- and low-side service hoses (found in the accessory box)
to the 1/2" acme connections below the handle on the unit. Connect the
blue low-side hose to the bottom fitting, marked “LP.” Connect the red
high-side hose to the top fitting, marked “HP.”
8. Attach the red (front) 15-foot temperature probe, the blue (rear) 30-foot
temperature probe, and the optional airflow sensor to the appropriately
labeled connections at the upper rear (see diagram on Page 7).
9. Press NEXT. The ACR2005 will now evacuate all air from the internal
circuit.
IMPORTANT: Introduction of contaminated refrigerant into the unit
will require service which is NOT COVERED under warranty. It is
imperative that a new tank of R-134a refrigerant be used. The tank
should be tested for contamination before installation. The tank of
refrigerant used for initial fill of the internal storage vessel is not
automatically identified. Introduction of contaminated refrigerant
into the unit will require service which is NOT COVERED under
warranty.
10. The ACR2005 will now prompt you to test the source tank. Attach a 1/2"
Acme/low-side service adapter to the source tank (do not invert). Use the
vapor valve on refillable tanks. Attach the blue low-side service hose to
the adapter, and open the coupler. Open the source tank valve.
11. The unit will now test the tank. When the test is complete, the unit will
prompt you to install the source tank. Install a tank of new R-134a
refrigerant on the lower shelf of the unit, below the handle. The ACR2005
can handle 30 lb. (14 kg) or 50 lb. (23 kg) tanks. The source tank should
be installed so liquid refrigerant is available (normally the tank is
inverted). Secure the tank to the unit by placing the strap around the tank,
and tightening it.
• A virgin tank should be inverted.
• A refillable tank should be upright with hose connected to the liquid
valve.
12. Press START and the ACR2005 pre-charges the tank with 12 pounds of R-
134a available for charge. This process takes approximately 15 to 20
minutes.
To avoid the possibility of lost refrigerant, virgin tanks should be checked for
leakage around the tank valve after being connected and the valve opened. If
leakage is found, close the valve, and keep it closed at all times EXCEPT
during manual tank refill. (Before pressing the MANUAL TANK REFILL
button, open the valve. Close the valve immediately after the process is
complete). The manufacturer does not reimburse for lost refrigerant.
The ACR2005 is now set up and ready for operation.
