UNIT INSTALLATION

3. 

Models 600x600

: cut the false ceiling to a maximum dimension of 625x625mm. For a panelled ceiling remove

one panel of 600x600mm.

Models 600x1200

: cut the false ceiling  to a  maximum dimension of 625x1225mm. For a panelled ceiling remove

two panels of 600x600 or one of 600x1200mm.

2.

 

Ensure there is sufficient space around the unit to service it. Where there is a false ceiling, ensure that there is

enough space to provide access. Where there is a false panelled ceiling ensure that there is sufficient adjacent

space to remove the panels.

1. The unit should be positioned centrally within the room. The ceiling must be horizontal to ensure that the unit

is on level and that condensate water can drain away thoroughly. The unit must be installed in a position where

there is sufficient strength in the structure to support the weight of the unit. The false ceiling must have at less a

height of 308 mm.

4. Install the suspension rods to the ceiling, the rods should

have three nuts and two washers, as in next figure.  The

setting up template can be used to indicate the position for

the suspension rods.

5. The water connections should be positioned before unit is installed.

NOTE: 

Before marking the fixing points to the ceiling,

ensure that the unit is positioned in the correct orientation

taking into account of where the electrical cabinet is required.

Ensure that water pipes can be run easily. When the unit

is fixed it is not easy to change position.
