Safety valve
Visually check that the drain of the water safety valve
is not clogged
The points to be checked are:
- the flow rate of the safety valve is optimal;
- if there is dirty water coming from the safety valve:
- open the valve until the discharged water no longer contains dirt;
- wash the system and install an additional water filter (possibly
a magnetic cycloidal filter).
We recommend performing this maintenance multiple times
per year.
•
Electrical part
Perform a visual check of the electrical part of the outdoor unit
checking the electrical connections and the wiring.
In case of faults on the wiring or electrical connections, the
replacement must be performed by qualified personnel (for
example the Immergas Technical Assistance Service).
•
Antifreeze protection valve
Replace the antifreeze protection valve every 3-7 years (accor-
ding to the quality of the water).
Replace the antifreeze protection valve if it does not close
properly.
•
Vacuum breaker valve
Disassemble the vacuum breaker valve and clean the cartridge
with water.
In case of malfunctions replace the vacuum breaker valve.
Keep the area around the unit clean.
ATTENTION!
The coolant inside the unit is slightly
flammable.
If the refrigerant were to come out, coming
into contact with the flame of a burner, a hea-
ter or a gas kitchen, it may cause a fire or form
noxious gas.
Switch off the flammable heating devices, air
the room and contact an authorised company
(e.g. Immergas Technical Assistance Service).
DO NOT use the unit until a qualified techni-
cian has repaired the leaking component that
is leaking coolant.
ATTENTION!
•
DO NOT perforate or burn the com-
ponents of the coolant cycle.
•
DO NOT use cleaning materials or tools to
accelerate the defrosting process other than
those recommended by the manufacturer.
•
Keep in mind that the coolant in the system
is odourless.
COOLANT GAS RECOVERY IN CASE
OF LEAKS
If you wish to recover the coolant gas in
case of a leak in the circuit:
•
DO NOT use te automatic gas recovery fun-
ction by means of “Pump down”.
Possible consequence: self-combustion or ex-
plosion of the compressor due to air mixing
with the flammable coolant.
•
Use a separate recovery system so that the
compressor of the unit is NOT operated.
During the coolant recovery operation with the Pump
Down, stop the compressor before removing the
coolant piping.
If the compressor is still operating and the stop valve is
open during coolant recovery with the Pump Down,
air will be sucked into the system.
Due to the abnormal pressure in the coolant cycle, the com-
pressor may brake and the unit may be damaged.
The coolant recovery operation with the Pump Down extracts
all the coolant from the hydronic unit and sends it to the
compressor module.
1) Remove the cover of the liquid stop valve and the gas stop
valve.
2) Set the stand by mode from the control panel (insert stand by
icon) ad then access the assistance menu ->manual->Pump
Down-> On
3) After ±2 minutes, close the liquid stop valve with a hex key.
4) Check that a vacuum was achieved on the pressure gauge.
5) After ±5 minutes, close the gas stop valve and stop the Pump
Down from the assistance menu ->manual ->Pump Down -> Off
