Connection of heating coil
The installation must be carried out by an
authorized installer. By turning the fan heater,
pipe connections are possible on both sides.
The heating coil is equipped with aluminum ns
and copper pipes with smooth connections, for
soldering or compression ttings. For correct
inlet and outlet connection of the heating coil,
see dimension drawing.
NOTE: Care must be taken when connecting
the pipes. Use a pipe wrench or a similar
tool to grip the air curtain connections to
prevent straining of the pipes and subsequent
water leakage during connection to the water
supply pipe-work.
The connections to the heating coil must be
equipped with shut off valves to allow trouble-
free removal. The heating coil must not be
connected to a mains pressure water system or
an open water system.
Prior to use, the coil must be vented. A vent
valve should be connected at a high point in
the pipe system. Vent- and drain valves are not
included.
Electrical installation
The Champ fan heater is intended for
permanent installation. The installation, which
should be preceded by an isolator switch with
a contact separation of at least 3 mm, should
only be wired by a competent electrician and in
accordance with the latest edition of IEE wiring
regulations.
Champ is tted with a 1.8 m cable with plug
for connection to earthed outlet sockets. The
wiring diagram can be found on the inside of
the lid.
Control
Champ is prepared for FC control system,
available in several packages for different
requirements. The FC packages are ordered
separately. The fan heater has an integrated
PC board which is connected to the selected
external control system FC. Communication and
sensor cables are connected to the PC board
via grommets on the back of the unit. The FC
PC-board is placed in a box inside the unit. The
box is opened by removing the two screws and
unhook the lid. The cable will prevent the lid
from falling.
Should more than one fan heater be
controlled by a single FC, an additional
communication cable FCBC per unit will be
required.
Settings are made on the FC control panel.
See manual for FC. FC will activate the after-
run: when the heat is switched off, the fan will
continue to run for a short while to cool the
elements.
Opening the unit
The top and the bottom are easy to open and
tted with hinges for simple installation and
maintenance. Remove the two screws to open
the top or the bottom. The FC control box is
found under the top lid of the unit when the
water pipes are to the left, seen from the front.
Cleaning/maintenance
To ensure the performance and reliability of the
unit, regular inspection and cleaning must be
carried out. Inspection must be carried out at
least twice a year and cleaning when needed.
Filters require maintenance at least 4 times a
year.
Inlet and exhaust grilles, fans and elements
can be vacuum cleaned or wiped using a damp
cloth. Use a brush when vacuuming to prevent
damaging sensitive parts. Avoid the use of
strong alkaline or acidic cleaning agents.
The power supply to the unit must be
disconnected during all service, repair and
maintenance work.
Fan
Cleaning intervals of the fan depends on local
conditions and the lter used (if any). When
the lter section SWF is used and indoor air
quality is normal, cleaning once a year is usually
sucient. If the fan blades are not cleaned,
noises and vibrations may occur, which may
damage the bearings of the fan. If vibrations/
noises persist after cleaning, contact an
authorized technician. When the lter section
is used, inspection can be carried out by the
service hatch on the side of the lter section.
Basic lter SWFTN
If used, the basic lter SWFNT must be checked
at least 4 times a year and vacuum cleaned
when necessary. The lter is accessible from
both the top and the bottom of the unit. See
Opening the unit and pictures in introduction
pages.
Mounting of the extra air director SWLR
The extra air director makes it possible to direct
the air sideways. It is mounted to the unit by
hooking it onto the existing air director.
