Do NOT install the unit in places such as:
▪ In places where a mineral oil mist, spray or vapour may be
present in the atmosphere. Plastic parts may deteriorate and fall
off or cause water leakage.
▪ Sound sensitive areas (e.g. near a bedroom), so that the
operation noise will cause no trouble.
▪ The foundation must be strong enough to bear the weight of the
unit. Take the weight of the unit with a domestic hot water tank full
of water into account.
Make sure, in the event of a water leak, water cannot cause any
damage to the installation space and surroundings.
