Vitocell 300-V/-B Start-up/Service
Inspection and (if necessary) cleaning of tank must take
place within 2 years of initial start-up and as required
thereafter.
In the event that the building is unoccupied and not heated
and the danger of frost within the structure exists, the
tank as well as the heat exchanger coil must be drained.
In case the heating system is filled with an antifreeze
(which must be of non-toxic composition), only the tank
must be drained of domestic water and all valves in the
domestic hot water and domestic cold water
piping except for the main fill valve must remain open.
Ensure the DHW recirculation pump is deactivated
(if applicable).
Ensure main power supply to equipment, the heating
system and all external controls has been shut down.
Take precautions in all instances to avoid accidental
activation.
1. Check heating side and domestic water side adaptors
for leaks. Tighten if necessary.
2. Check sensor well for leaks. Tighten if necessary.
Verify proper operation of temperature and pressure relief
valve (T&P valve).
Clean tank encloser panel with a commercially available
alcohol-based glass cleaning agent and a soft clean
cloth.
