Condensation disposal
F version
corresponding copper joint (external diameter
19mm) for horizontal FR- FCR units, ensuring
that the joints are sealed with suitable tape.
For vertical versions F - FC, if the
supplementary condensation tray is used,
connect the disposal to the junction at the
bottom of the tray itself.
Pour water slowly into the condensation tray
and ensure that it runs out correctly towards
the disposal without leaving traces or dripping.
Check that there are no cracks in the
condensation disposal pipes or incorrect
sloping.
3.2.3 Electricity connection
WARNING! Turn off the power before
connecting to the electricity supply and com-
plete the plumbing connections first and
ensure they are secure.
Ensure that the electricity supply is 230V - 50Hz
monophase and that there is an earth cable.
The electricity supply, where a fan heater is
mounted, should be protected and controlled
by an adequate load (minimum 3 mm. Contact
opening) omnipolar switch and a 2A - 250V
fuse.
The fan heaters come without control panels
as there are various types to choose from.
Carry out the mounting operations for the
specific control panel according to the model
chosen and the type of installation (on the
side of the appliance or remote on a wall).
After mounting the control panel, connect the
electricity cable to the appropriate live, neutral
and earth terminals on the fan heater, inserting
the cable through the cable grip and cutting the
wires so that the yellow/green earth wire is
slightly longer than the other two. This precaution
means that if the wires are accidentally
detached, the earth wire is the last to come out
of the terminal (fig. 13).
4. STARTING UP
4.1 CHECKS
4.1.1 Before starting up the fan heater, ensure
that all current rules and regulations have been
followed both with regard to heat generators and
to cooling systems, as well as those applying to
plants, including the fan heaters themselves.
4.1.2 Ensure that the monophase 230 V
~
50 Hz
electricity supply and the earth cable are
connected to the appropriate terminals in the
appliance.
4.1.3 Ensure that water is circulating correctly
and bleed air using the appropriate bleed valves
situated on the collectors of the heat exchange
system.
4.2 SWITCHING ON
(references to control panel functions are as in
fig. 14).
a) Preparing the fan heater;
- version 1 controls:
put switch (A) in the "ON" position.
If there is one(in the electronic or 2 - pipe
microprocessor thermostats), put the
