NOTE:
1) During cold weather,with ambient temperature above 0 ºC (32 ºF) operate the air conditioner at
least once per month,for a period of 10 to 15 minutes.This will lubricate the seals to prevent them
becoming brittle and help prevent the loss of refrigerant from the system.
2) The system is equipped with an environmentally safe refrigerant,R134a.Never recharge the air
conditioning system with refrigerant other than R134a as this will result in loss of cooling and
permanent damage to all air conditioning components
