NOTICE:
Do not operate the cooler compressor before charging refrigerant as the cooler compressor will not work
properly without any refrigerant, and will overheat.
3. WARM UP ENGINE
(
a) Warm up the engine at less than 1640 rpm for 2 minutes or more after charging the refrigerant.
NOTICE:
Be sure to warm up the compressor by turning the A/C switch on after removing and installing the cooler
refrigerant lines (including the compressor) to prevent damage to the compressor.
4. INSPECT FOR REFRIGERANT LEAK
(a) After recharging the refrigerant, check for refrigerant gas leakage using a gas leak detector.
HINT:
Be sure to use a gas leak detector that is compatible with HFO-1234yf (R1234yf) systems.
(1) Perform the operation observing the following instructions:
Stop the engine.
Secure good ventilation (the gas leak detector may react to volatile gases other than
refrigerant, such as evaporated gasoline or exhaust gas).
Repeat the test 2 or 3 times.
Make sure that some refrigerant remains in the refrigeration system.
HINT:
When the compressor is off: approximately 392 to 588 kPa (4.0 to 6.0 kgf/cm
2
, 57 to
85 psi).
