For Technicians:
When positioning the sauna heater, observe the minimum safety
distances (see Fig. 1).
Observe the specifications on volumes of the sauna cabin (see Fig. 7).
Observe the specifications on ventilation of the sauna cabin
(see Fig. 9).
If this sauna heater is used for public saunas or saunas that may
be switched on by a separate remote-control system/ the door of the
sauna room must be fitted with an interlock such that the stand-by mode
setting for remote operation is disabled if the sauna door is opened when
the stand-by mode setting for remote operation is set.
The electronic and electric system should be mounted in a way so
that incoming air will not interfere with it. The control must be mounted
outside the sauna cabin.
Wiring and repairs must be done by a certified electrician.
Follow the Minimum Safety Distances when mounting the heater
(see Fig. 1).

Heater Installation
It is recommended that the heater is placed to the wall nearest the door.
The air circulation created by the door should work together with the hot air
generated by the heater. For safety and convenience, follow the minimum safety
distances as provided in Fig. 1. Follow the cubic volumes given in the Technical
Data in page 7. Do not install more than one heater in a sauna room unless you
follow the special instructions for tandem-heater installation.
A certified electrician must do the installation of the heater to ensure safety and
reliability. Improper electrical connections can cause electric shock or fire. Refer
to the electrical diagram in page 7.
An electrical supply cable must be connected to the terminal block inside the
control unit through the cable channel. The cable must be 5-core HO7RN-F type
or its equivalent. To connect the cable, open the side of the heater where
terminals are located (see Fig. 5).

Water distribution nozzle
MUST be positioned on the

avoid short circuits caused by
accidental leaks.
The heater comes in a set with a water accessory: water funnel, holder, hose and
water distribution tube. Mounting brackets are also enclosed. Screw the brackets to
the heater and to the wall to secure the heater to prevent it from falling down.

The water funnel and hose is necessary when installing the heater on a recess wall.
It is used to easily transmit water into the heater stones. Insert firmly the silicone
hose to the nozzle of the funnel and the distribution tube to tighten it. You may use the
holder if you wish to hang the funnel on the wall. See illustration below.
Place the funnel on the area that is accessible for putting water into it. Funnel must
be placed higher than the heater to ensure even water distribution on the stones.
When water in poured into the funnel, the water is distributed evenly to the heater and
generate a pleasant steam inside the sauna room. Cut short the hose when necessary
to avoid water trap. Set an interval on pouring water into the heater to have proper
radiant steam.
Stones store heat energy to efficiently vaporize the water that touches it to main-
tain the correct humidity inside the sauna room. It is recommended that all stones
should be rinsed before using to remove any stains or dust that can cause unpleasant
odor during the first few times of using the heater. The stones must be removed at least
once a year or every 500 hours whichever comes first. Small stone pieces less than
35mm in diameter must not be loaded into the heater because they will block the
air circulation and will cause overheating that will damage the heating element.
Slide up the water distribution tube to remove. Place enough stones and place back
the water distribution tube afterwards.

Insulation
Rotating the heater
The sauna must have proper insulation on the walls, ceiling and door. One square meter
(m²) of uninsulated surface increases the cubic volume by approximately 1,2m³ when
determining the power requirement of the heater. Refer to Technical Data.
Ensure that moisture proofing is appropriate for the sauna room.The purpose of this is to
prevent spreading of moisture to the other rooms or wall structure. Moisture proofing
must be placed between heating insulation and panel.
Thermal and moisture proofing need to be installed according to the following order
from outside to inside.
• The recommended minimum thickness of the thermal insulation in the walls is
50 mm and in the ceiling 100 mm.
• It is possible to use carton- or aluminum foil laminate as a vapor barrier, which is
affixed over the insulation aluminum foil inwards.
• Leave at least 20 mm air slot between vapor barrier and inside panel
• To prevent gathering of the moisture behind the panel leave the slot between
wall panel and ceiling.
In case you need to rotate your heater for wiring convenience or use, remove the screws
below the heater to remove the catchbasin to transfer it to the opposite side, same as
the heater brackets.
Empty the catch basin for excess water and crumbles of stones.

Air Ventilation
To have a soothing sauna, there should be a proper mixing of hot and cold air inside
the sauna room. Another reason for ventilation is to draw air around the heater and
move the heat to the farthest part of the sauna. The positioning of the inlet and outlet
vents may vary depending on the design of the sauna room or preference of the
owner.
The inlet vent may be installed on the wall directly below the heater (Fig. 9A). When
using the mechanical ventilation, inlet vent is placed at least 60 cm above the heater
(Fig. 9B) or on the ceiling above the heater (Fig. 9C). Through these positions, the
heavy cold air that is blown into the sauna is mixed with the light hot air from the
heater, bringing fresh air for the bathers. It is recommended that the inlet vent must
have a diameter of 5-10cm.
The outlet vent should be placed diagonally opposite to the inlet. It is recommended
that the outlet vent is placed under the platform in a sauna as far as possible from
the fresh air vent. It can be installed near the floor and stale air is or led outside
through a pipe to a vent in the sauna ceiling, or under the door (to the washroom).
In this case, the sill slot must be at least 5 cm and it is recommended that there is
mechanical ventilation in the washroom. The size of the exhaust should be twice
that of the inlet.
