Connection of heating coil
The installation must be carried out by an
authorised installer.
1. The fan heater must not be connected
to the hot mains water or steam. The
maximum permissible temperature and
pressure are indicated on the fan heater
type plate at the connection pipes.
2. Capacity, water temperature, flow and
pressure drop can be found in the table for
the respective size.
3. The fan heater must be connected so that
the coil can drain water during shutdown
when there is a freezing hazard.
4. At the outlet of the fan heater or centrally
in the installation, a venting valve is
installed.
5. A connected pipe system to the fan heater
must be set so that they do not load the
inlet and outlet pipes of the fan heater.
6. The water inlet is connected to the heater’s
lowest placed pipe and the outlet at the
highest position according to the arrows
in Figure G. The connection is R3/4” on
SWXCE12 and R1” on the SWXCE22.
7. When tightening the couplings on the
connection nipples, these must be held
so that no torque is transferred to the fan
heater’s inlet and outlet pipes, see figure H.
Important! Make sure the entire system is
close to the water connection. Any potential
leakage can cause expensive water damage.
8. The connection of brass to the coil should
be protected against corrosion in aggressive
environments, for example with vulcanic
tape that can withstand the surrounding
environment, see figure I.
Electrical installation
The electrical installation should be carried
out by a qualified electrician in conformity
with prevailing regulations. The appliance
should be supplied via a triple-pole switch
with at least 3 mm breaking gap.
The fan motor is connected to a detached
terminal box, which is mounted on a wall
next to the unit (0,85 m cable).
The cable glands used must meet the
protection class requirements.
See wiring diagrams.
