Planning
Take into account the duct battery's capacity for the
established airflows when sizing the depth of the ground
source heating well (see Technical data). Take the pressure
loss caused by the duct battery into consideration when
sizing the airflows.
The duct battery must always be mounted horizontally,
so that condensate which is formed is led to a drain as
planned.
Reserve at least 500 mm servicing space at the sides of the
unit.
