MAINTENANCE
It is advisable to do maintenance works every 1.000 operating hours as well as at the beginning of each cooling season.
•
Coils:
At least once a year, clean condenser coils with water and detergent, then dry with air at a low pressure. Never
clean with wire brush.
•
Fans and motors:
Adjust transmission belt at least twice during the first month of operation and then check every 1.000
hours. Fan and motors do not need additional lubrication.
•
Drainage system:
Verify condition and good operation of the drainage tray and siphon.
•
Refrigeration circuit:
Check for oil refrigerant leaks, n
oises or system’s vibrations. Take measurements of temperatures
and pressures of components and record them on the maintenance form.
•
Electrical circuit:
Make sure that all electrical connections -wires, contactors, and terminals- are properly tight. Record
the values (volts and amperes) of each compressor and fan motor. Verify the starting current. Check the good operation
of all relays, pressostats and phase sequence relay of Scroll compressor.
•
Air filters
: Clean filters after the first 4 operating hours and then every 3 months (or even before). Wash filters with water
and detergent, rinse thoroughly and let dry.
Before performing any service or maintenance operation, turn off the main power
switch of the system to avoid any personal injuries. Locked it so that nobody other
than a qualified technician can switch on electrical power.
