General Precautions for Removing and Installing the Air
Conditioning System Components (continued)

8. Always use a DOT approved tank to store the used and recycled refrigerants.
9. The Groundsmaster 360 air conditioning system uses R134a refrigerant. Do
not use other refrigerants in the system.
Note: The capacity of the air conditioning system is 1.55 kg (3.43 lb) of
R134a refrigerant.
10. The refrigerant containers (either full or empty) are under pressure and
the pressure increases if you heat them. Do not expose the refrigerant
containers to high-heat sources or flame.
11. Ensure that the work area is properly ventilated to prevent any accumulation
of the refrigerant or other fumes.
12. Ensure that the caps are always placed on the pressure hose ports. These
caps prevent refrigerant leakage from the system.
13. The air conditioning drier-receiver component is used to collect moisture
that reduces the air conditioning performance. If the air conditioning
system is opened for the component repair or replacement, ensure that the
drier-receiver ports are plugged to prevent damage to the drier-receiver.
If either the compressor or air conditioning expansion valve is replaced,
replace the drier-receiver.
14. After you install the air conditioning components, have a certified air
conditioning service technician evacuate the air conditioning system
completely, properly recharge the system with R134a refrigerant, and perform
the leak test on the system.
