2.2 Positioning
2.2.1 The ComfoAir 155 WM unit must be installed vertically and can be either wall or floor mounted to enable
effective condensate drainage in either a kitchen/service cupboard or secured to a vertical structure in the loft
space. If located within a cold space, it is recommended that the bottom of the unit is insulated to prevent
freezing around the condensate connection. Duct spigots must be upright at top of unit.
2.2.2 It is not advisable to install the unit directly above a bedroom or living room ceiling, or in an area that is part of a
living area or bedroom.
2.2.3 Consideration must be given to allow for adequate access for servicing, maintenance and any fault diagnostics
(See Section 2.5 Access for Maintenance).
2.2.4 The unit can be configured for right and left hand installation at a touch of a button by following the steps within
the Commissioning Wizard
(See Section 3.1.4 Commissioning Wizard)
and does not require any internal
changes.
(See Figures overleaf for ducting configuration).
