3. Instructions for the installer

THE PERSON INSTALLING THE SAUNA HEATER SHOULD LEAVE THESE INSTRUCTIONS AT THE PREMIS-
ES FOR THE FUTURE USER.

3.1. Preparing for sauna heater installation

Check the following before installing the sauna heater.
1. The ratio of the heater's input (kW) and the sauna room's volume (m
in the table 2 on page 7. The minimum and maximum volumes must not be exceeded.
2. The sauna room height must be a min. of 1900 mm.
3. Glass and stone surfaces will extend the pre-heating period. Each square meter of glass or stone ceiling or wall
3
adds 1.2m to the sauna room's volume in terms of needed heater input.
4. Check page 6 Table 1 for a suitable fuse size (A) and the correct diameter of the power supply cable (mm²) for
the sauna heater in question.
5. Conform to the safety clearance around the sauna heater as specified in Table 2 on page 7. There should be
enough room around the sauna heater control equipment for maintenance purposes. Also a doorway can be
considered for maintenance purposes.
6. . If the the heater is integrated in the sauna benches, the bench model must allow lifting of the lower bench and
its frame without tools. The warranty will not cover dismantling and reassembly of sauna benches.
3.2

Heaters installation

Follow the safety clearance specifications on page 7 table 2 and image 3 when installing the sauna heater.
The sauna heater is a floor-standing model. The base must be solid, because the sauna heater with rocks weighs
about 100 kg.
The sauna heater is levelled by the adjustable legs.
The sauna heater is fixed on the floor from its legs by the provided metal fasteners (2 pcs). This will keep the safety
clearances intact during use.
Walls or ceilings must not be clad light-weight cladding, such as incombustible protecting board, because they may
cause a fire hazard.
Install the heater so that the type plate can be read. The main switch is on the side of the contactor case. Refer to
the contactor case operating manual for more specific instructions
Only a single sauna heater is allowed per sauna room

3.3 Connection of the sauna heater to the mains

The sauna heater must be connected to the mains by a qualified electrician and in compliance with current regula-
tions. The sauna heater is connected with a semi-permanent connection. Use H07RN-F (60245 IEC 66) cables or a
corresponding type. (See Table 1 on page 6) Other output cables (signal lamp, electric heating toggle) must also
adhere to these recommendations. Do not use PVC insulated cable as a connection cable for the sauna heater. A
multipolar (e.g. 7-pole) cable is allowed, if the voltage is the same. In the absence of a separate control current
fuse, the diameter of all cables must be the same, i.e. in accordance with the front fuse. Example: the diameter of
the cable connected the light indicator and the circuit command equipment on a 9kW sauna heater has to be a
minimum of 2.5 mm². The connecting box on the sauna wall should be located within the minimum safety clearance
specified for the sauna heater. The maximum height for the connecting box is 500 mm from the floor, (see Image 2
on page 6) If the connecting box is located further than at 500 mm distance from the heater, the maximum height is
1000 mm from the floor. The sauna heater heating elements may absorb moisture from air, e.g. during storage.
This may cause bleeder currents. The moisture will be gone after a few heating sessions. It is not recommended to
connect the electrical supply through the residual current device switch. If so, the heater must have a residual cur-
rent device switch of its own. Adhere to the effective electrical safety regulation when installing the sauna heater.
