IMPORTANT
If the unit version without the integrated switch cabinet has been selected, neither the valve
nor the valve actuator are supplied. In this case, these are on-site services.
NOTE
The figure shows schematics only of the hydraulic connection of the heater. The exact hydrau -
lic connection must be carried out at the discretion of the heating specialist.
If the heat exchanger is the last component in front of the on-site duct, a duct-side inspection
opening must be provided directly on the register. This is used for inspection and cleaning.
Function
The heater is included in the control system for the room or supply air temperature. The heat output is metered by reg-
ulating the corresponding actuating valve.
IMPORTANT
At temperatures below freezing point, the heat exchanger must be either drained and blown
out with compressed air, or filled with a commercially available antifreeze with corrosion in -
hibiting additive due to the risk of freezing and corrosion.
5.7.2 Connection of heater / cooler module (option)
A pump hot water heater (PWW) and pump cold water air cooler (PCW) can be provided for the additional heating and
cooling of the supply air.
To avoid condensate transfer into the duct, a droplet eliminator (TA) is installed behind the cooler.
„
The additional unit must be flanged to the main unit (see chapter “5.3 Assembly of separated housing” on page
25 ).
„
The supply and return lines of both heat exchangers must be professionally connected.
NOTE
Do not mix up the feed and return lines when connecting the pipelines.
The medium inlet is located on the air outlet side (fig.: Counterflow principle for heat exchang -
er connection).
