DEFROSTING CONTROL
To prevent ice from forming on the finned coil, during the winter
heating phase, each machine is equipped with an automatic
defrosting device, controlled by the microprocessor through
pressure probes and timer.
The
symbol flashes on the control panel during defrosting,
indicating this status.
CHECKS DURING AND AFTER THE FIRST COMMISSIONING
Once the startup has occurred, check if:
- On three-phase models, the indicator light on the phase monitor is
on; in this case start the compressor.
- The current absorbed by each compressor phase is lower than the
maximum one indicated in the Technical Data table
- The equipment is working within the recommended operating
conditions (see page 29)
- The hydraulic circuit is totally vented
– The equipment performs a stop and a subsequent restart.
It is not allowed to operate the unit with an inverted phase
(only three-phase models
INACTIVITY FOR A LONG PERIOD
To switch off the heat pump, whatever its operating mode, only
use the control panel
After switching off the unit:
– Turn OFF the remote switch (if present)
– Deactivate the internal terminal units, by turning off the switch of
each appliance
– Turn OFF the main system circuit breaker
– Close the water taps.
If the outside temperature may drop below zero, there is the
risk of frosting.
The temperature of the circulating water inside the heat pump
should never exceed 60°C.
Should the unit be connected in parallel to a boiler, close the
unit cocks during the boiler operation. The temperature of the
circulating water inside the heat pump should never exceed
60°C.
ORDINARY MAINTENANCE
Periodic maintenance is essential to preserve the appliance
efficiency both from the functional and the energy-saving point of
view.
The maintenance plan which the manufacturer’s Support
Technical Service or the refrigeration serviceman must observe,
at least once a year, features the following operations and
checks:
– - Expansion tank pressure check (2 bar)
- Water circuit filling
- Water circuit check for presence of air
- Efficiency of safety devices
- Supply voltage
- Electrical input
– - Tightness of electrical connections
- State of compressor remote switch
- Efficiency of plate heat exchanger resistor
- Efficiency of compressor resistor
- Cleaning of finned coil (*)
- Cleaning of fan grilles
- Cleaning of condensate collection vessel (if installed).
(*) every three months.
For equipment installed near the sea, maintenance intervals
must be cut by half
It may be necessary to remove the chiller inspection panels during
maintenance operations.
In this case, proceed as follows::
– - Undo the fixation screws and remove the inspection panels.
– At the end of maintenance operations::
– Replace the panels proceeding in reverse order.
