Isuzu Tilt Slide FYJ2000 Instruction Manual page 477

The air conditioning system will not be able to cool the cab interior effectively if the
refrigerant level is low. Accordingly, the refrigerant level must be topped up whenever
necessary. Please contact your Isuzu Dealer whenever refrigerant must be added.
ADVICE
• Operating the air conditioning while the refrigerant level is too low leads not only
to poor cooling performance but also to air conditioning system damage.
• This vehicle uses the new refrigerant HFC134a (R134a) in the air conditioning
system. No other type of refrigerant can be used.
In order to protect the environment, care must be taken to ensure that
refrigerant gas is never released into open air. When refrigerant must be
replaced, therefore, please contact the nearest Isuzu Dealer or other service
facility equipped with a gas recovery installation system.
Precautions to Observe in Hot Regions
When using the vehicle in a hot region, there is a greater possibility of the engine
overheating. Prevent overheating by observing the following rules:
1. Do not use well water, river water or other hard water for engine coolant because
water scale is likely to occur.
2. If mud, dirt or dust adheres to the front of the radiator, cooling performance will be
impaired, so check and clean the radiator from time to time.
3. In a hot region the battery fluid will be consumed quickly, so check the fluid level
frequently.
