INSTALLATION
Horizontal or ceiling installation (FWXM-series)
Using the paper template, trace on the ceiling the position
of the two fixing brackets and the two rear screws. Using a
suitable drill, make the holes and insert the toggle bolts (2
for each bracket); fix the two brackets. Do not over-tighten
the screws. Position the machine on the two brackets,
keeping it in position and then fix the two screws into the
rear toggle bolts, one on each side.
Make sure that there is sufficient inclination of the unit
towards the drainage pipe to facilitate the water drainage.
Fully tighten all 6 fixing screws.
For installation of the FWXM-series, horizontal
condensation collection basin accessory kits are available
EKM(10/15/20)COH.
The installation of FWXV-series units in horizontal position
is prohibited.
Carefully check the inclination of the exhaust pipe.
Any counterslope of the discharge line can cause
water leakage

NB:
the nominal diameter, unless otherwise indicated,
always refers to the internal diameter.
To avoid the formation of surface condensation, it is
always recommended to install electric valve kits, except
in the case where an electrical control (eg electrothermal
head) is provided upstream of the appliance. The choice
and sizing of the hydraulic lines must be made by an
expert who must operate according to the rules of good
technique and the laws in force, taking into account that
undersized pipes cause a malfunction.
To make the connections:
-
position the hydraulic lines
- tighten the connections using the “spanner and
counter spanner” method
-
check for any leaks of liquid
-
coat the connections with insulating material.
The hydraulic lines and joints must be thermally
insulated.
Avoid partially insulating the pipes.
Do not over-tighten to avoid damaging the insulation.
Use hemp and green paste to seal the threaded
connections; the use of Teflon is advised when there is
anti-freeze in the hydraulic circuit.
