Step Action
1 Connect the heat exchanger using the counterflow principle (water flow direction opposite the air flow direction in the
unit).
2 Connect the pre flow up or down depending on the air direction.
3 Carefully vent the heat exchanger.
4 Check all of the piping for leaks.
5 Ensure that the piping and the heat exchanger are integrated into the unit potential.
ATTENTION
If the unit version control has been selected, neither the valve nor the valve actuator are sup-
plied. In this case, these are on-site services.
NOTE
The figure shows schematics only of the hydraulic connection of the heater.and the cooler.
The exact hydraulic connection must be carried out at the discretion of the heating specialist.
If the heater/cooler module is the last component before the on-site duct, a duct-side inspec-
tion opening must be provided directly on the register/droplet eliminator. This is used for
inspection and cleaning.
Function
Heater and cooler are integrated into the temperature control. The temperature is set by controlling the cold water and
hot water control valves.
ATTENTION
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.
