Installation instructions
‐
Read through these instructions with care before you begin the installation process.
‐
The electrical installation must be performed by a qualified electrician.
‐
Separate instructions for electrical connections come with the control unit and/or the
circuit diagrams of these instructions.
‐
Beware of sharp edges and use a long‐sleeved shirt and protective gloves during the
installation and while piling the stones.
1. Remove the protective plastic covering from the heater.
2. Choose the place for the heater according to the required safety distances. The
minimum safety distances to inflammable surfaces for Monolith electric heater,
measured from the heater's frame outwards, are 100 mm on the sides and the back of
the heater and 800 mm to the ceiling (Page 9).
3. Pay attention to the ventilation of the sauna room, the ideal placement for the
thermostat's sensor and the control unit. (PAGE 7‐8)
4. Lift the steel frame from the resistor casing/stand.
5. Open the element box located at the underneath the heater and connect the five‐pole
electric cable through the socket seal to the terminal block inside the box. (PAGE 6)
6. Attach the other end of the cable to the control unit and connect it according to the
specified instructions inside the control unit (controller).
7. Take the cable from the control unit (controller) either to the socket or electrical main
center.
8. Test that all the heating elements function properly by switching the heater on. If all the
heating elements heat up, you can close the element box panel. (If one or more of the
heating elements fails to heat up or another problem occurs such as a fuse blowing out,
contact the manufacturer's technical support.
9. Place the heater in its place. Check the safety distances to flammable materials before
piling on the stones.
10. Lift the steel frame on top of the resistor casing/ stand and straighten the heater by
adjusting the adjustable legs.
11. PILING OF THE STONES: Read separate instructions (PAGE 10). In communally or publicly
used saunas we recommend the use of ceramic Kerkes stones around the heating
elements (www.kerkes.fi). Kerkes stones support and help preserve the heating
elements and they do not disintegrate prematurely due to high temperature changes.
Note that the use of soapstone and natural stones is allowed only on the outer edges and
on the top of the heater.
