3.3. Heater fence

It is necessary for safety and should be constructed
of softwood to match sauna interior. See figures 3
and 4 for clearances from sauna heater. Fence should
be attached to wall and should not be placed higher
than top of heater below rock line.

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 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 clear-
ances as per figures 3 and 4. After final hook-
up, electrical contractor should secure heater
to its place with provided screws or bolts.
2. See applicable wiring diagram for heater model
(figure 5). 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
be done by a licensed electrician, who must fol-

low wiring diagram provided and adhere to local
codes. Use proper AWG rated wire size and use
copper wire suitable for 194 °F (90 °C) within
sauna walls. Use grounding terminals provided
in sauna heater and control unit to properly
ground the equipment as per NEC and local
codes.
3. Inside the heater box there are two signs.
Please place the metal "CAUTION" sign on
the interior wall of the sauna room directly
above the heater in a visible place (screws and
nails included). Place the metal "WARNING"
sign outside, on the door of the sauna room.
"MAINTENANCE INSTRUCTIONS" are at the
end of this manual.

3.5. Electric heater insulation resistance

When performing the final inspection of the electri-
cal installations, a "leakage" may be detected when
measuring the heater's insulation resistance. The
reason for this is that the insulating material of the
heating resistors has absorbed moisture from the
air (storage, transport). After operating the heater
for a few times, the moisture will be removed from
the resistors.
Do not connect the power feed for the heater
through the RCD (residual current device)/GFI
(Ground Fault Interrupter)!
