ACR2005 Refrigerant Service Solution
Setup Instructions
TESTING SOURCE TANKS
Robinair recommends that all source tanks be sampled before installation on the
ACR2005. The ACR2005 does not automatically test the contents of the source
tank before adding refrigerant to the internal storage vessel. If a source tank
contains contaminants, these contaminants are transferred to the internal storage
vessel.
After a tank fill, the unit samples the contents of the internal storage vessel. When
the internal storage vessel is contaminated, the unit displays:
INTERNAL TANK CONTAMINATION or ID-MALFUNCTION
CONTACT SERVICE
Turn off the unit and restart to clear the message. If the message does not clear,
contact the Technical Support Line immediately.
The ACR2005 locks out all functions until a certified service center
decontaminates the machine. This decontamination is not covered by the warranty.
To sample a source tank, follow these instructions:
1. Recover any refrigerant left in the hoses by pressing the RECOVER key.
2. Attach a 1/2" Acme/low-side coupler to the source tank. Use the vapor valve
on the refillable tanks.
3. Attach the blue low-side service hose to the adapter, and open the coupler.
4. Open the source tank valve.
5. Turn the ACR2005 ON.
6. Press the SNAPSHOT key.
7. Press the START key.
8. The ACR2005 now samples the contents of the source tank.
9. Once the sampling process is complete, close the tank valves, recover the
refrigerant from the hoses, and reattach the blue low-side hose to the low-side
port on the unit.
10. If the source tank is not contaminated, follow the instructions for TANK
REFILL.
If the source tank is contaminated, close the tank valve. Disconnect the blue
hose, and remove the tank from the unit.
