If local codes require external application of thermal insulation
blankets kits, the manufacturer’s instructions included with the
kit must be carefully followed.
Application of any external insulation, blankets, or water pipe
insulation to this water heater will require careful attention to
the following:
• Do not cover the temperature and pressure-relief valve.Do
not cover access panels to the heating elements.Do not
cover the operating or warning labels attached to the water
heater or attempt to relocate them to the exterior of the
insulation blanket.Do not block the air inlets/outlets and
the top cover.
• Do not cover water heater control unit.
4.8 Fill the water storage tank
▶ Open DHW connection (Fig. 5, [6]) and one or more hot
water taps.
▶ Open storage tank cold water inlet (Fig. 5, [8]).
Storage tank filling starts.
▶ Close hot water taps only when water flow is free of air
pockets.
▶ Connect the appliance to the power supply via fixed wiring
installation, including earth conductor.
▶ Rotate circulation pump speed selector to position „III“.
