12 SUPPLY CONNECTIONS
12.1 HOSE CONNECTIONS
Connection to the combustion and waste air outlet takes place at the rear of the combustion air
conditioning unit. Provided for this purpose are standard DN 4/6 hose couplers.
N O T E !
Do not confuse the hose connections for the combustion and waste air
outlet; the connections are marked appropriately.
When all lines have been connected, they must be checked for leaks (see
15.7).
When connecting the hoses to the appropriate hose couplers, the following must be observed:
N O T E !
Tightness of the connection can only be ensured when the connecting hose
has a straight terminating edge (use a hose cutter).

Loosen the sleeve nut of the clamping ring fitting by turning counter-clockwise; the nut must be
removed carefully from the screw fitting to prevent the clamping ring, which is arranged loosely in
the nut, from being lost.

Slip the sleeve nut over the connecting hose.

Slip the clamping ring on to the connecting hose with the thicker flange facing towards the nut.

Fit the hose to the nipple in the screw fitting.

Tighten the sleeve nut hand-tight.
The hose is now fitted non-slip and pressure-proof.
For connection to the condensate pipe, a
G 1/8”i thread is provided on the underside of the automatic
float condensate drain. An appropriate connection fitting must be provided by the customer. In order to
prevent return flow of the condensate, the condensate pipe should be installed with a gradient.
For connection of the compressed-air/instrument-air line for the BA version, a
G 1/4” connection
thread is provided on the rear panel of the combustion air conditioning unit; an appropriate connection
fitting must be provided by the customer.
Appropriate connection fittings are optionally available by M&C.
