Precautions On Refrigerant Recovery; Precautions On Refrigerant Charge; Precautions On Replenishing Compressor Oil - Suzuki GRAND VITARA Owner's Manual

7B-3 Air Conditioning System:
• Never use heat for bending pipes. When bending a pipe, try to make its bending radius as slight as possible.
• Keep internal parts of air conditioning free from moisture and dirt. When disconnecting any line from system, install
a blind plug or cap to the fitting immediately.
• When tightening or loosening a fitting, use two wrenches, one for turning and the other for support.
• Tighten bolts to specified torque.
Tightening torque
Refrigerant line bolt: 12 N·m (1.2 kgf-m, 9.0 lb-ft)
• Route drain hose so that drained water does not make any contact to vehicle components.

Precautions on Refrigerant Recovery

When discharging refrigerant out of A/C system, always
recover it by using refrigerant recovery and recycling
equipment. Discharging refrigerant HFC-134a (R-134a)
into atmosphere would cause adverse effect to
environments.
NOTE
When handling recovery and recycling
equipment, be sure to follow the instruction
manual for the equipment.

Precautions on Refrigerant Charge

Charge a proper amount of refrigerant to A/C system
according to charging procedure described in recovery,
evacuation and charging. Refer to "Charge" in
"Operation Procedure for Charging A/C with Refrigerant:
".

Precautions on Replenishing Compressor Oil

When replacing air conditioning parts with new ones, it is
necessary to replenish oil by the amount supposedly
remaining in each part.
When Charging Refrigerant Only
When charging refrigerant without replacing any
component, replenish the same amount of measured oil
when recovering refrigerant (if not measure, replenish 20
cm 3 (20 cc) oil).
When Replacing Compressor
CAUTION
!
Be sure to use specified compressor oil or an
equivalent compressor oil.
Compressor oil is sealed in each new compressor (1) by
the amount required for air conditioner cycle. Therefore,
when using a new compressor for replacement, drain oil
from it by the amount calculated as follows.
"C" = "A" – "B"
"C": Amount of oil to be drained
"A": Amount of oil sealed in a new compressor
"B": Amount of oil remaining in removed
compressor
