Maintenance program
COOLING COIL
Verify the state of the coil; if necessary clean it as follows:
• in spring: clean using a vacuum cleaner (or compressed air).
• in summer: this being the hottest period, keep the coil as
clean as possible, with a vacuum cleaner (or compressed air)
and, if necessary, with water.
• in winter: clean with water (with the fan off ).
• if necessary (coil blocked) remove the fan and clean the coil
in the opposite direction to the air fl ow using a high pressure
water jet (this operationmust be performed by a technician
to avoid damage).
Check that the fan rotates freely without any abnormal noise.
Also check the current absorption.
(Th e fan's sealed lubricating system needs no maintenance).
COMPRESSED AIR CIRCUIT
If the air compressor consumes signifi cant quantities of oil, pe-
riodically wash the tubing as follows:
Disconnect the air inlet and outlet. Force a chlorinated solvent
(which must be neither strongly acid or alkaline) through the air
tubing with a centrifugal pump to remove the carbon deposits
(ensure the tubing is perfectly dry and free from solvent vapour
before reassembling).
