IMPORTANT
Inspection and (if necessary) cleaning of unit must take
place within 2 years of initial start-up and as required
thereafter. Reinspection time must not exceed 2 years.
The internal cleaning of the Vitotrans including its potable
water connections may only be performed by a licensed
professional heating contractor. There are no user
serviceable parts on this equipment.
Clean the Vitotrans enclosure with a commercially
available alcohol-based glass cleaning agent and a soft
clean cloth.
If a water softener system is used in the domestic cold
water inlet piping into the Vitotrans, the water treatment
system should be inspected (serviced) at the same time.
If a drinking water filter is used in the main line, the
filter cartridge should also be investigated. All external
equipment must be serviced regularly and function
properly.
