Warning to the
installer!
This installation is subject to building
regulation approval, notify the Local
Authority of intention to install.
Warning to the
installer!
Use only manufacturer’s
recommended replacement parts.
Tap water connection
Hot and cold water are connected to pos (74) (hot
water) and (73) (cold water).
The attendant expansion vessel (107) must be con-
nected to the hot water system.
The heat pump should be supplemented with an elec-
tric water heater if a bubble pool or other significant
consumer of hot water is installed.
If the heater is equipped with a valve connection Ø of
15 mm, this should be replaced with an equivalent
(split) Ø 22 mm coupling.
Appropriate heaters are COMPACT 100-300 for floor-
mounting and EMINENT 35-100 for wall-mounting.
1. Split the valve coupling.
2. Attach the valve coupling section to the heater’s
incoming cold water.
3. Attach the mixing valve section to the heater’s out-
going hot water.
4. Plug the split on the valve coupling section.
