5.7.1 Connection of hot water heater (option)
For heating the supply air, a pump hot water air heater (PWW) can be used. Extraction and emptying of the heat exchang-
er must be carried out on-site. The heat exchanger has an air-side frost protection thermostat.
The additional unit must be flanged to the main unit (see chapter
“5.3 Assembly of separated housing” on page
25 ).
The feed and return lines are to be professionally connected on-site.
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 ex
-
changer connection).
IMPORTANT
Counter-hold using a suitable tool (e.g. pipe wrench) during connection of the heat exchang-
ers in order to avoid damage.
Install pipes and connections in such a way that the heat exchangers remain freely accessible
for maintenance.
Maximum working pressure: 16 bar
Maximum hot water flow temperature: 120 °C
Valves and actuators must be installed professionally. Please note here whether a version with a 2-way or 3-way
valve is to be set up.
For electrical connection of the actuator, see the circuit diagram.
