Ducted units are designed to be hung on a wall (brackets available as a kit), suspended from a ceiling 
(installer supplied fittings), or to stand on a flat surface. Whichever method is used it is essential that the 
mounting surface is capable of supporting the unit's weight. Leave space around the unit for air circulation 
and access for installation and maintenance. 

 

FLOOR MOUNTING

 

 

Using the appropriate side of the packing carton as a template, (centres marked A), mark out and drill 4 
holes to suit maximum M8 bolts (also see Fig. 1). Secure the unit to the floor. Discard the 4 stabilizing 
brackets and 8 screws.

SUSPENSION MOUNTING

 

 

The installer must supply 4 x M8 threaded rods with 16 nuts and 
washers to suit. 

 

IMPORTANT:   

The stabilizing brackets provided 

MUST 

be used when suspending a unit. 

Fit the stabilizing brackets to the top corners of the backpanel and front face using the No. 

10 screws provided, (2 per bracket). 

If these brackets  are omitted the unit will be subject to unacceptable movement on 

compressor start (Fig. 2). 

 

Where long drops of M8 rod are used, it is advisable to incorporate flexible pipes in the suction and 
expansion lines. 

 
 

Using the template printed on the side of the packing 
carton, (centres marked A), mark  out the ceiling and 
drill  4  holes  to  suit  M8  screwed  rod,  (see  Fig.  1). 
Raise  the  unit  to  the  required  height  and  pass  the 
screwed rods through the mounting holes in the units 
feet  and  stabilizing  brackets.  Secure  the  unit  with  a 
nut  and  washer  on  either  side  of  each  stabilizing 
bracket  and  two  nuts  and  washers  underneath  each 
foot mounting hole, (Fig. 2).
