ATTENTION!
Never pass compressed air through the dryer when it is stopped.
Always start the dryer 5 minutes before slowly opening the air
inlet valve. If the airflow is to bestopped only switch the dryer
off after closing the air inlet.

ATTENTION:
Hot and moving parts enclosed, disconnect the
mains supply before removing this cover.

WARNING:
Risk of electric shock can cause injury or death.
Disconnect all remote electric power supplies before servicing.

ATTENTION
1 Fully drain the piping before connectingthis unit to theexter-
nal water piping (cold water, make up water, ect.).
2 Fitting of a standard strainer is also strongly recommended
on the inlet water piping.

ATTENTION: SCHRADER VALVE
1 This unit is equipped with refrigerant as for quantity and kind clearly shown
in operating manual and with identification label.
2 Any ordinary test and / or refrigerant recharge by means of connections can
take place only after refrigerant evacuation. The evacuation must be pro-
portional to dimensions and length of the connections used. The use of the
valve can be justified only when the dryer is not in working order.
3 During the unit guarantee period, the Schrader valve can be used by autho-
rized staff only, otherwise any damage caused by a wrong refrigerant
recharge will not be under warranty.
