3.4. Electrical Connections

The heater may only be connected to the electrical
network in accordance with the current regulations
by an authorised, licensed professional electrician.
The heater must be connected with a fixed all
poles disconnection device, that provides full
disconnection under overvoltage category III
conditions. The connection must be made according
to current local and general regulations.
The wiring diagrams are included in the control
unit's installation instruction.
Further instructions concerning exceptional installa-
tions can be obtained from local electrical authorities.
1. Remove heater from carton and place in
proper location in sauna room. Observe proper
clearances as per figures 4 and 5. After final
hookup, electrical contractor should secure
heater to the floor or on the wall with required
screws or bolts.
2. See applicable wiring diagram for heater model
(figure 6). Heater must be permanently installed
by using seal tight conduit between the heater
and the wall of the sauna room (pigtails or plugs
are not allowed in the sauna room). Wiring must

3.5. Installing the Heater

See figure 7.
1. Fasten the wall-mounting rack on the wall by
using the screws which come with the rack.
NOTE! There must be a support, e.g. a board,
behind the panel, so that the fastening screws
can be screwed into a thicker wooden material
than the panel. If there are no boards behind
the panel, the boards can also be fastened on
the panel.
2. Make sure the clip fastens in the hole properly.
3. Lift the heater to the rack on the wall so that
the fastening hooks of the lower part of the
rack go behind the edge of the heater body.
Lock the edge of the heater onto the rack by a
screw.
