3.5. Electrical Connections
The heater may only be connected to the electrical network in accordance with the current regulations by an authorised, professional electrician.
Refer to the chart in table 2 to determine the wire size and circuit protection required. The complete sauna system should be properly grounded as per NEC or as required by local codes. A grounding terminal is provided in the wiring compartment of each heater, complate the wiring according to the appropriate wiring figure 10.
See table 1 for required clearances. Any wiring within internal Sauna walls must be rated for 90°C (194°F) and copper wire must be used. Run wire through seal tight flex conduit from wall to heater and connect to junction box.
Note! If connection to heater will be made at a later time, bring flex into Sauna room
mm)from floor, and leave 3' (900 mm) of flex for hookup (can be cut to right lenght later).
Further instructions concerning exceptional in- stallations can be obtained from local electrical authorities.
3.6.Electric heater insulation resistance
When performing the final inspection of the electrical 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.
Note! A ground fault interrupter (GFI) shoud not be installed in and does not belong in a Sauna.
3.7.Testing of Sauna heater
Before testing heater, fill rock cavity with igneous stones provided with heater and fasten rock guard at top of heater. See item 1.1." Piling of the Sauna rocks".
1.After Sauna heater has been properly wired, according to appropriate wiring diagram and local codes, turn Sauna breaker on in the main breaker panel. (Note! Electrician must label "Sauna" breaker.)
2.Turn thermostatic (heat) control to on position (this is located on your heater). Set timer to 10 or 15 minutes.
3.Within 5 minutes, you should be able to feel heat from heater elements when holding your hand over heater.
4.If Sauna does not heat, refer to troubleshooting information.
5.It is normal for smoke to appear during the first heating, as protective element coating needs to burn off. TURN SAUNA ON FOR 1 HOUR BEFORE USING THE FIRST TIME, TO ELIMINATE SMOKING.
