2. INSTALLATION

2.1 Clearances & Service Access
Refer to Specification Sheet supplied for minimum
clearances. If multiple units are to be placed side-by-
side then allow at least 2m between coil faces.
Filter slides are fitted within the unit. Access to the filter
access door should be considered when designing
return and supply air ductwork.
2.2 Mounting
The unit should be fastened to a firm flat horizontal
base using the holes supplied in the mounting
channels. When the unit is being installed on a roof it is
recommended that the unit is installed on a substantial
structure with vibration isolating pads or mounts. If
placed on the ground or concrete pad, use rubber pads
or mounts to give 20mm min. ground clearance.
Flexible duct connections are recommended between
the supply and return ducts and the unit.
