Observe the following points:
Only install the unit in enclosed spaces.
Mounting systems must be capable of bearing the weight of the unit,
including any accessories.
Ensure that suitable fixings (screws, plugs, etc.) are used which correspond.
3.2 Unit installation
The foundation for the fan coil unit must be level. This is to avoid torsion of the base
frame andunit casing. Torsion of the unit casing would affect the built-in components
in a way they arenot designed for.
Fasten the base frame to the foundation by means of bolts. Galvanized steel frame
withholes are provided for securing the units.
3.3 Connecting the chilled water
Before the on-site piping and the unit chilled water connection is set up, the chilled
water system should be shut off and secured against being opened unintentionally.
Connection to the pipe system is made by the pipe contractor. Cooling coils must
always be connected in counter flow (supply and discharge pipes are marked) and so
that the expansibility or own weight of the pipe system does not load the pipe
connections of the coils. The connections of the cooling coils are designed as flanged
pipes. Fixing set (bolts + washers+ safety washers + nuts), AISI 304 will be delivered
for each flange
Cooling coils are provided with drip pan with drain through the base frame for
condensate extended through the access side. Clean cooling coils by flushing with
water, and drip pan as well as drain must be kept clean to avoid formation of algae.
All on-site pipes for the cooling medium must be insulated against condensate
formation.
When all connections have been completed, all screw connections should be
tightened and checked that they are free of mechanical stress.
During fitting, the connection nut on the cooling coil should be countered using a
suitable tool.
At the beginning of the fitting procedure, remove the covers of the water inlet
and outlet pipes.
Fit the connections, ensuring they are free of mechanical stress.
Lead the pipes off at a right angle to the side or to the rear.
Seal the connections.
Screw on the connections.
