WATER HEATING - UNVENTED

instantaneous - DE range

Electrical

Supply – 380-415V 3-phase. The unit must be connected to an all-pole isolation switch with a minimum gap of 3mm.

Water Supply and Fittings

Supplied from cold mains water supply only – max 20°C. Standard UK water fittings may be connected to the outlet providing they exceed the minimum flow rates.
