INSTALLING UKU ELECTRICAL CONTROL DEVICE

Before installation disconnect the electric heater from the power supply in the switchboard.
The control devic 1e must be installed outside the steam room, at the user’s eye level next to the door or according to the manufacturer’s recommendations.
If your main controller s2 upports the use of the WIFI connection it must be installed where the appropriate reception is available.
The device must be installed in a dry place. The protection degree of the device is IPX4. The power cables must be anchored via the provided cable gland.
Do not exceed a room temperature of 104 oF (40 oC) and relative humidity of 95%.
Before powering the controller, it must be made sure that the controller box is sealed so that there is no possibility for pollution or only for dry, non-conductive pollution to occur on the components inside the controller while in use. All the cable inlets and the box shall be properly sealed.
CAUTION! The control device must be connected to the mains permanently without plugs. A method to disconnect all poles from the mains (a circuit breaker) must be installed. The power cables of the heater controller must meet the requirements of UL 62 in the US and CSA 49 in Canada – the minimum temperature rating of 140 °F (60°C). The cables’ cross-section depends on the power of the heater. See the heater manual. Our recommended wire size for controller power cable: 10 AWG for 4.5 kW and 6 kW heaters, 6 AWG for 9 kW heaters, 10 AWG for 12 kW heaters (double-wire), 6 AWG for 15 and 18 kW heaters (double- wire). Always let the correct cable size be approved and installed by a qualified electrician.
NB! A method to disconnect all poles from the mains (a circuit breaker) must be installed on the power circuit.
