HA-30 < BASIC INSPECTION > [WITH HEAT PUMP SYSTEM] LUBRICANT Lubricant Adjusting Procedure for Compressor Replacement INFOID:0000000010122111 1. Drain lubricant from removed compressor and measure lubricant amount. 1. Turn the compressor so that it faces downward, and drain the compressor oil from high-pressure port (A) and low- pressure port (B). 2. Measure total amount of lubricant that is drained from removed compressor. 2. Drain lubricant from a new compressor that is calculated accord- ing to the following conditions. CAUTION: If lubricant amount that is drained from removed compressor is less than 60 m (2.1 Imp fl oz), Example: Lubricant amount to be drained from a new compressor when replacing compressor [m (Imp fl oz)] [D = 60 (2.1), α = 5 (0.2)] 150 (5.3) − [60 (2.1) + 20 (0.7) + 5 (0.2)] = 65 (2.3) 3. Install compressor and check the operation.
