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
Table 1 on page 3. The minimum and maximum volumes must not be exceeded.
2 The sauna room height must be a min. of 1900 mm.
3 Uninsulated and masonry stone walls extend the preheating time. Each square metre of plastered ceiling or wall surface
3
adds 1.2 m to the sauna room's volume.
4 Check page 3 Table 2 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 specified safe clearance around the sauna heater. Please refer to page 3.
6 If you want to install your Piccolo sauna heater in a corner, detach the wall mounts from the heater, twist them 180
degrees and then reattach them. Refer to Figure 5 on page 3.
There should be enough room around the sauna heater controls for maintenance purposes. Also a doorway can be
considered as a maintenance area.
Installation
Follow the safety clearance specifications on
page 3 when installing the sauna heater.
Walls or ceilings must not be clad with
fibre-reinforced plaster board or other
light-weight cladding, because they may
cause a fire hazard.
Only a single sauna heater is allowed per
sauna room.
Installing the sensor near a supply air vent
The sauna room air should be exchanged six times in an
hour. The diameter of the supply air pipe should be
between 50 and 100 mm.
A circular air supply vent (360°) must be
installed at least 1000 mm away from the sensor.
An air supply vent with a flow-directing panel
(180°) must be installed at least 500 mm away from
the sensor. Air flow must be directed away from the
sensor.
Ceiling installation of the sensor
In ceiling installation, a 5-mm hole must be drilled to the sensor case to allow any condensed water to drain.
Do not spray water directly towards the sensor or splash water at it with a sauna scoop.
Heating the sauna
Before turning the sauna heater on, make sure the sauna room is suitable for taking a sauna bath. When heated for the first time,
the sauna heater may emit some odour. If you detect any odour while the sauna heater warms up, disconnect the sauna heater
briefly, and air the room. Then turn the sauna heater back on.
You should turn the sauna heater on roughly an hour before you plan to take a sauna bath, so that the stones have time to heat up
properly and the air warms up evenly in the sauna room.
If you encounter any problems, please contact the manufacturer's warranty service shop.
Pleasant, smooth sauna bath temperature is about 70 °C.
Do not put any objects on the sauna heater. Do not dry clothes on the sauna heater or anywhere in its vicinity

Remove the nut and the rubber grom-
met from the strain relief bushing. Make
a vertical split in the spot where the
lead-in rubber grommet aligns with the
hole. Insert the control panel's RJ10
and the cable through the strain relief
bushing and insert the cable through
the hole you just made. The sensor
cable can be inserted directly through
the hole. Tighten the strain relief
bushing nipple.
