Before Beginning the Hose Flushing Procedure

WARNING: This page does not describe the selected car, but rather 8 other vehicles, including the 2008 GMC Yukon XL, 2008 GMC Yukon, 2008 Chevrolet Tahoe, 2008 Chevrolet Suburban, and 2008 Chevrolet Avalanche. However, it is still accessible from the selected car via links, so may be relevant.
  1. Always allow the ACR2000 to complete the hose flush cycle to assure that all oil and refrigerant is removed from the hoses and the ACR2000 flow control circuit.
  2. Assure the ACR2000 has at least 4.08 kg (9 lb) of chargeable refrigerant before proceeding.
  3. A Low Filter Flow message displayed during the hose flushing process indicates that the hose couplers are not connected or open.
