ROUTINE SERVICE
To ensure continued full efficiency of the process dryer unit, maintenance
procedures should be performed as follows:
Removal of the three covers, by means of the four screws in the corners of
each cover, will allow access for all the maintenance to be carried out.
1. Clean the surface of the evaporator and condenser coils by blowing
the dirt out from behind the fins with compressed air. Hold the nozzle
of the air hose away from the coil (approx 6”/150mm) to avoid
damaging the fins. Alternatively, vacuum clean the coils.
2.
Check that the fan is firmly secured to the motor shaft and that the
fan blade is positioned centrally inside the housing and that it
rotates freely. The motor is sealed for life and therefore does not
require lubrication.
3.
To check the refrigerant charge, run the unit for 15/20 minutes and
briefly remove the cover. The evaporator coil should be evenly frost
coated across its surface. At temperatures above 20
°
C, the coil
may be covered with droplets of water rather than frost. Partial
frosting accompanied by frosting of the thin capillary tubes,
indicates loss of refrigerant gas or low charge.
4.
Check all wiring connections.
