DXD/H SPR FAN COIL UNIT INSTALLATION
DXD/H fan coil units are designed to be installed within a ceiling void. Air discharge should be via insulated ducting,
connected to 250mm diameter spigots (200mm diameter spigots also available) and to appropriately sized discharge
plenums/grilles. Ducting and discharge facilities are supplied by others and are not included with the fan coil units.
Similarly, return air arrangements, via ducting or to the ceiling void, must also be provided.
The installer must ensure that the mounting suspension points are capable of supporting the operating weight of the unit,
(refer to the table below).
UNIT FIXING
1. Before lifting the unit into position, mark out the four outer fixing points as shown below, and fit suspension rods of
appropriate length and diameter, (minimum recommended thread size M8). Two inner, central fixing points are
available for installer convenience. DO NOT lift the unit by its spigots, drain tray or electrics box when raising it
into position.
2. Lift the unit into position and secure with appropriate fixings (as shown).
The use of lock nuts will stabilize the unit.
NOTE:
The drain tray is designed with a natural fall to ensure complete
drainage. It is essential, for the correct operation of the condensate
removal system, that the unit is square and level.
