3.14 Siphon [13]
An air treatment unit usually contains components where condensation occurs. In such cases, ap-
propriate measures must be applied to remove the condensation responsibly.
A siphon must be connected to each condensation outlet or overflow connection. It is not per-
mitted to connect several outlet pipes to a single, shared siphon. The siphon water trap (H) must
be higher than the maximum under pressure and over pressure in mmWK for the appliance in re-
lation to atmospheric pressure (1mmWK= 10 Pa)
Appliance over pressure (Pa)
H(mm) = —————————————

The height between the condensation outlet and the overflow connection must also be of height
H (mm).
Siphon under pressure. [14]
This siphon is used where there is under pressure in the unit. The siphon should not be filled with
water following installation. The siphon will set its own level on start-up. If the siphon becomes
dry, the valve ensures that the siphon is closed off.

The siphon pipe must not be connected directly to the sewage, but must be able to flow freely into
the sewage. Always ensure that parts carrying the (condensed) water cannot freeze. When starting
up the appliance after a long period out of operation, each siphon must first be filled with water.
3.15 Drip catcher [8]
If a drip catcher is fitted, it can be dismantled, and replaced after cleaning.
3.16 Shutting down
Appliances must be shut down by skilled personnel. It is important to be familiar with the installa-
tion, operating and maintenance instructions as well as the maintenance instructions for air han-
dling units and any peripherals in advance. Disregarding these instructions could result in danger
to the personnel carrying out the work, and damage to the appliance.
The air handling unit forms part of an air handling system.
For short periods of time.
– Terminate the demand for heat/cooling.
– Open the return air valve and close the outside air valve
– Shut off all valves
– Shut off the central heating pump
– Shut off water and hand valves
– Drain off any parts susceptible to freezing
– Blow dry the heat exchanger and connections fully with air
– Ventilate the unit fully until everything is dry.
– Remove the water from the siphons
– Switch off the mains switch and turn the unit off
