3.2 INSTALLATION
CAUTION
CAUTION
DANGER!
Installation must only be carried out by qualified
technicians,trained to work with air-conditioning and
refrigeration systems.Incorrect installation could lead to unit
malfunctioning and a consequent deterioration in
performance.
DANGER!
The unit must be installed according to national or local rules
in force at the time of installation.
For installation,follow the instructions set out below:
Remove the external casing(in versions I), unscrewing the
screws which secure it to the structure,as following indicated.
Mark out the fixing points on the wall or ceiling,either by marking
through the drillings in the unit itself,or by referring to the
measurements given in “7 DIMENSIONS”. Maintain a gentle fall
in the condensation drainage pipe, to ensrue that water escapes
properly.
3.2.1 HYDRAULIC CONNECTIONS
Connection to the system
Setting up the condensate drainage system
IMPORTANT!
It is most important that the hydraulic connections are made
with great care by specialised fitters.
IMPORTANT!
The water coils can be partially drained through the drain
valves.
To drain them completely,they should be blown out with an
air-jet.
CAUTION
Connect the unit to the water system by means of the fittings which
are marked Flow and Return.
All the water coils,including the optional extras,are equipped with air
bleed-valves next to the upper union,and with water drain valves
need to the lower union.
All the valves can be opened and closed with screwdrivers or
allenkeys.
Bleed the air contained in the circuit.
Lag the connection pipes and any valves titted with
anticondensation material 10 mm thick or install the auxiliary
drain.
Pour water into the condensation collector tray and check
that the liquid drains properly,following it right through to the
exit of the draintube.If it does not,check the fall and look for
possible blockages.
When installation is complete,it is necessary to :
The condensation drainage system must be set up with an
adequate fall,to ensure that the water escapes properly.
Following are directions for setting up a proper condensation
drainage system.
