If the heating circuit is filled with anti-freeze, and de-
pending on the concentration of the mixture, the fol-
lowing points must be observed:
●
The heating capacity of the heat pump is reduced
●
The COP value becomes worse
●
The output of circulation pumps used on site is re-
duced, and the specified free compression for in-
tegrated circulation pumps decreases
●
You must ensure the materials in the components
used are compatible with the anti-freeze mixture

10 Insulating hydraulic
connections
Insulate hydraulic lines in accordance with local regu-
lations.
1. Open shut-off devices.
2. Perform a pressure test and check for leaks.
3. Insulate external piping on site.
4. Insulate all connections, fittings and pipes.
5. Insulate the condensate drain to ensure protec-
tion against frost.
6. Enclose the unit completely to ensure protection
against rodents.
7. Protect hydraulic and electrical cables on site
against rodents.
IMPORTANT
When using the accessories CPS, make the hydrau-
lic insulation UV-resistant on site.
IMPORTANT
When using the accessories HVLD, seal the transi-
tion to the KG pipe with the end cover EDH 32/160
(accessories).
