Task Operating mode
Check the value of the analogue
sensors
Install the pressure gauge calibrated to check the analogue sensors .
Install a thermometer calibrated to control the sensors.
Check the position of all sensors Check the good positioning and the fi xation of all sensors.
Check anti-vibration mountings, for
wear and tear.
Visually check anti-vibration mountings on compressors and centrifu-
gal fan. Replace if damaged.
Check Glycol concentration in the wa-
ter circuit
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
Check casing and equipment
corrosion
To treat and neutralize eventuals rust spots
Check the watertightness of the unit
and it’s accessories
Verify the gaskets, if cracked or ripped, repair them or replace them.
Check the watertightness of the water
circuit
Check for water leaks and repair if it’s needed.
Check the water pump
When the installation is going to work with percentages of glycol
up to 20% and water temperatures below -5ºC, even do we use a
specifi c closing for the water pump, it is advisable to clean the wa-
ter pump’s closing every year and a half, in order to avoid leaks by
crystallization.
Plate exchanger
Prove the general isolation state and tightness of the water connec-
tion and the freeze protection.
Check the expansion vessel if
appropriate
Measure the pressure under the different water modes ( from +7°C
to +45°C)
