Sauna Heater Manual
xii. Fill the rocks loosely around the elements, try to use the larger rocks between the elements
and use the smaller ones for the top.
xiii. To prolong the life of your sauna you can use a heatproof board behind and above the
heater to prevent charring, for commercial cases this should be more seriously considered.
10.3. Wiring of sauna heater and components
Remove the cover panel and connect power supply wire and control cable through the wire
anchorage to the Terminal as per fig 8 and replace the cover panel.
If wiring single phase, it is only the input connections into the OCSB control box L1, L2, L3 that
need to be linked (see fig2a). Do not short circuit output from the control box to sauna heater or
across the live terminals of on the heater.
The correct size heat proof cable is required to the heater from the control box. This is not
supplied as standard but can be bought at the required length from Oceanic Saunas Ltd or a
local electrical wholesaler.
