Before Installing Steam Generator Parts Use the following information together with the consultation of your contractor, architect or designer in determining all factors necessary in providing a suitable and safe steam room. For illustrative purposes only. Check that the supply voltage is suitable to your steam generator. Ensure that the steam generator kilowatt corresponds to the volume of your steam room. Refer to Technical Data (Page 13).

Instructions of Use There are four different operation modes in the unit: Off, On, Standby and Drain. The user can easily switch between different modes, making the steam bathing more convenient with less energy consumption. To use steam room the control unit needs to be in the On mode. In the On mode, the steamer is active, the temperature in the steam room will be kept in the preferred, set temperature, with occasional discharge of steam.

2. Level probe cleaning Maintenance 1. Decalcification Tap water contains impurities, for example lime, that can cause calcium deposit and block the internal parts of the steam generator. To prevent this and prolong the lifetime of steam generator it is recommended to have a water filter and water softener. They are connected to the water source of the steam generator’s water inlet. SAWO Decalcifying Solution can be used for decalcification.

Power Wiring Electrical Diagrams Do not connect the elements to the power supply directly. Only a qualified electrician should do the Electrical wiring connections. CONVERTABLE Check the power supply before installing your unit. Single Phase connection, a 220-240V supplied is required. Use two-wire supply source and equipment grounding wire of single phase connection. A 90ºC / 600V (HO7RN-F) rated insulated copper wire is required for SAWO steam generators.
