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.
Function
Coolers are integrated into the temperature control. The temperature is set by controlling the cold water actuating valves.
On-site siphon
A siphon is also required on-site for the cooler.
„
Each pan drain must be fitted with a separate siphon.

If the device version control has been selected, neither the valve nor the valve actuator are
supplied. In this case, these are on-site services.
The figure shows schematics only of the hydraulic connection of the cooler. The exact hydrau-
lic connection must be carried out at the discretion of the heating specialist.
If the cooler module is the last component before the on-site duct, a duct-side inspection
opening must be provided directly on the register/droplet eliminator. This is used for inspec-
tion and cleaning.
At temperatures below freezing, the heat exchanger must be either drained and blown out
with compressed air, or filled with a commercially available antifreeze with corrosion inhibiting
additive due to the risk of freezing and corrosion.
The drain pipe and the siphon are to be kept frost-proof on-site.
