Mechanical Maintenance
1.
Check the tension of the fan motor, fan wheel, compressor and control box fixing
bolts.
2.
Check that no water has penetrated into the control box.
Evaporator Coil
It is recommended that the finned coils are inspected regularly to check the degree of
fouling. This depends on the environment where the unit is installed, areas by the sea
can cause increase corrosion and an approved sprayed film coating is recommended.
For coil cleaning proceed as follows:
1.
Remove fibers and dust collected on the evaporator face with a soft brush (or
vacuum cleaner).
2.
Clean the coil with the appropriate cleaning agents
Water Circuit Checks
1.
Clean the water filter if fitted.
2.
Purge the system to remove any air.
3.
Verify the correct operation of the water flow switch.
4.
Check the status of the thermal piping insulation.
5.
Check the water flow by checking the water inlet and outlet temperature
difference.
6.
Check the concentration of the anti-freeze protection solution (ethylene glycol or
polyethylene glycol).
7.
Check the status of the heat transfer fluid or the water quality.
8.
Check the expansion tank for signs of excessive corrosion or gas pressure loss and
replace it, if necessary.
9.
Check that the water pressure safety valve is not leaking
10.
Check that the air vent valves are not leaking system water
