Check with a calibrated anemometer the flow rate
displayed by CLIMATIC
|
Check the position of all
sensors

accessories (pressure tapping tube).
•
Check and clean if
necessary all fresh air
grids

Check electric heater
element for excessive
corrosion
Turn off the unit; Pull the electric heater out of the
heater module box and check the resistances of traces
of corrosion; Replace resistance as required;
|
Check anti-vibration
mountings, for wear and
tear.
Visually check anti-vibration mountings on compressors
and centrifugal fan. Replace if damaged.
•
Check Glycol
concentration in the HWC
circuit and/or in the water
condenser circuits
Check the glycol concentration in the pressurized water
circuit. ( a concentration of 30% gives a protection
down to approx.. -15°C) check the circuit pressure
|
Gas burner module check
for corrosion
Pull out the burner to access the tubes
(refer to Gas burner section in the IOM)
