2.5 Access for Maintenance
Footprint of ComfoAir 155 CM
2.6 Condensate Drain
2.6.1 It is important that any condensate MUST be drained away.
• The ComfoAir 155 CM unit is provided provided with a condensate drain located at the side of the unit
(See Figures 6-8)
and can be rotated for ease of connection.
The drain plug allows a condensate drain hose (21.5mm diameter) to be push connected and solvent
welded/sealed. Please ensure a water tight seal is achieved.
2.6.2 The drain must have a 5º fall and can either be chased into the wall or run downwards from the unit into the
nearest waste water network. Ensure that steps are taken to minimise the risk of mechanical damage to the
drainage pipe work.
IMPORTANT NOTE: The condensate drain must incorporate a waterless
trap or U bend to create an air block and avoid leakage of smells back
into the unit. If the unit is installed within a loft space, please ensure
that the condensate drain is insulated to prevent against freezing.
2.6.3 In some instances, a condensate connecting point will already be provided as part of the building design.
The position of this point, relative to where the unit is to be installed should be checked for any connection
misalignment and any necessary adjustment made before proceeding any further.
