Collector system
Installation and filling
Installation and filling of the collector system should comply with
applicable laws and regulations. Soil used for refilling around the
collector hose must not contain stones or other sharp objects. Pressure
test the collector system before refilling to ensure that the system is
watertight.
When cutting the collector, it is important that no dirt or gravel enters the
system. This can cause blockages in the heat pump and damage
components.
Filling unit
A filling unit is included in the delivery and should be installed close to
the collector circuit inlet.
Expansion vessel, safety valve, pressure gauge
The expansion vessel, safety valve and pressure gauge are to be
provided by the dealer.
Collector circuit pump
Factory setting for the collector circuit pump is max (
Æ

setting may need to be adjusted to achieve the correct delta value (
Æ
Chapter 13.4 ). The value must lie within the grey area. To adjust the
value, turn the dial.
