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.

m. 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.
n. SETTING (hot gas valve)
Evaporating pressure in 0_C, with precision manometer con-
nected at evaporator outlet.
o. ATTENTION: SCROLL three---phase compressors.
If the compressor is noisy and the pressure on the (LP) gauge
does not decrease you should immediately invert two phases.
Please refer to the service manual for more details.
p. ATTENTION: Hot and moving parts enclosed, disconnect the
mains supply before removing this cover.
q. ATTENTION
1 Fully drain the piping before connecting this unit to the exter-
nal water piping (cold water, make up water, ect.).
2 Fitting of a standard strainer is also strongly recommended
on the inlet water piping.
r. WARNING:
Risk of electric shock can cause injury or death.
Disconnect all remote electric power supplies before servicing.
s. BSPP pipe threads
use supplied adapters
