MAINTENANCE

7.1 Cleaning

Use a vacuum cleaner and a damp cloth to clean the inte-
rior of the cooling unit, if needed.
Inspect the unit at least twice a year.
7.2 Handling refrigerant
Type R 407C refrigerant is used.
The refrigerant circuit is already charged when the unit is
delivered.
Warning
Under no circumstances shall unauthorised personnel be
permitted to open the refrigerant circuits, as long as gas
under high pressure is present in the circuits. Only the
technicians of an accredited refrigeration company shall
be permitted to modify or repair the refrigerant circuit s.
The CoolDX is equipped with a safety valve to prevent
excessively high pressure in the system if high tempera-
tures caused by a fire, for example.
Important
Contact Swegon Service if you detect any refrigerant
leakage.
Warning
If refrigerant is exposed to fire or in some other way
becomes superheated in the atmosphere, poisonous
gases can form.
We reserve the right to alter specifications.
Important
Charging with refrigerant must be carried out according
to the recommendations of the refrigerant producer.
