Conditioner - KAMAZ 5490 Operation Manual

CONDITIONER

The air conditioner regulates air temperature and
humidity in the vehicle cab.
Attention!
Air conditioning system works only with engine
working.
For normal operation of air conditioner com-
pressor it is necessary to switch it at least once a month
for 10 min.
In cold season it is suggested to engage condi-
tioner for 5-10 min. in a warm room. This provides
greasing of inner seals by oil primed in the system, pre-
venting their drying and corrosion.
Conditioner is to be topped up from time to time
(once in 1-2 years). Topping-up is carried out in a spe-
cialized service center.
