7 MAINTENANCE
7.1 Cleaning
If needed, clean the inside cleaning of the unit by vacuum
cleaning and wiping surfaces with a damp cloth.
Inspections should be performed twice a year.
7.2 Handling of refrigerant
The refrigerant used is R410A.
The refrigerant circuit is completely charged when the unit
is delivered.
Warning
Under no circumstances may the refrigerant circuit be
opened by unauthorised personnel, since it contains
gas under high pressure. Only an accredited refrigera-
tion company shall be permitted to modify or repair the
refrigeration circuit.
RX/HC is equipped with a safety valve to prevent exces-
sively high pressure in the system caused by e.g. a fire.
Important:
Contact Swegon Service in the event of leakage of
refrigerant.
Warning
If refrigerant is exposed to fire or in some other way
becomes superheated in the atmosphere, poisonous
gases can form.
7.3 Leakage tracing interval/
Obligation to report
Must be carried out according to the F-Gas Regulation
EU/517/2014 and associated local legislation.
7.4 Service
Only service personnel trained by Swegon should be per-
mitted to modify the chiller.
Important:
Filling of refrigerant must be performed in accordance
with the recommendations of the refrigerant manufac-
turer.
Avoid direct skin contact with refrigerant and lubricant.
Use tightly sitting protective glasses, protective gloves
and covering work clothes.
Arrange ventilation/point extraction.
In the event of eye contact
rinse the eyes using an eye-wash shower (or with luke-
warm water) for 20 minutes. seek a doctor.

8. TROUBLE SHOOTING AND LEAK-
AGE TRACING
8.1 Troubleshooting Schedule
Symptoms Possible cause Action
Compressor is not operating The voltage has been isolated.
Incorrect phase sequence.
The compressor safety circuit has been broken.
Defective compressor.
Check the operating/safety switch. Check the condi-
tion of the fuses.
Check and change the phase sequence.
Check, reset if needed.
Replace the compressor.
Too low capacity Leakage, inadequate refrigerant.
The voltage has been isolated.
No air flow or too low air flow across the evaporator.
Thermostat/Control equipment incorrectly set or defec-
tive.
Leak test, fill with refrigerant if necessary.
Check the operating/safety switch. Check the condi-
tion of the fuses.
Check the air flow.
Adjust the setting or replace faulty components.
The compressor switches off
because the low pressure sensor
has measured an excessively low
value.
Inadequate refrigerant.
No air flow or too low air flow across the evaporator.
The expansion valve is defective.
The low pressure switch is defective.
The cooling system is leaking. Tighten the leak and
charge with refrigerant.
Check the airflow.
Check, replace.
Check, replace.
The compressor switches off
because the high pressure sensor
has measured an excessively high
value.
No air flow or too low air flow across the condenser.
Excessively high exhaust air temperature.
The high pressure sensor is defective.
Check the air flow.
Check the exhaust air temperature.
Check, replace.
Significant freezing on the
evaporator.
The expansion valve is defective or incorrectly set.
No air flow or too low air flow across the evaporator.
Check. Replace or adjust setting.
Check the air flow.
8.2 Leakage Tracing
Leakage tracing should be carried out at least once per
year as a precaution. The leakage tracing inspection must
be documented.
If the system is leaking, this will become apparent firstly
by impaired performance, or if the leakage is substantial,
when the system does not operate at all.
If you suspect that the cooling system is leaking refriger-
ant, check the level of refrigerant in the sight glass located
on the heating circuit’s electrical equipment cubicle.
If you see continuous and a substantial amount of bub-
bling in the sight glass and the reversible heat pump
operates at appreciably lower capacity than normal, the
system is probably leaking. One or several bubbles appear-
ing when the chiller is started up, operation at reduced
capacity or normal operation need not necessarily indicate
a refrigerant deficiency.
If it is bubbling in the sight glass and the chiller operates at
appreciably lower capacity, call for qualified service help.
NOTE! Maintenance work in the refrigerant system is per-
mitted to be carried out only by an accredited inspectorate
(a company with requisite authorisation).
