Maximum total water piping length between indoor unit and
outdoor unit when using 1 1/4" piping
(a)
Precise water piping length can be determined using the Hydronic Piping Calculation tool.
The Hydronic Piping Calculation tool is part of the Heating Solutions Navigator which can
be reached via https://professional.standbyme.daikin.eu. Please contact your dealer if you
have no access to Heating Solutions Navigator.
▪ Mind the following spacing installation guidelines:
CAUTION
Install the indoor unit at a minimum distance of 1 m from other heat sources (>80°C)
(e.g. electrical heater, oil heater, chimney) and combustible materials. Otherwise the
unit may be damaged or in extreme cases catch fire.

INFORMATION
Serviceability may be impacted, if the indicated clearances cannot be maintained.
INFORMATION
If you have limited installation space, do the following before installing the unit in its
final position:
▪ The foundation must be strong enough to bear the weight of the unit. Take the
weight of the unit with a storage 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.
▪ The foundation must be level and smooth.
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.
▪ In places with high humidity (max. RH=85%), for example a bathroom.
▪ In places where frost is possible. Ambient temperature around the indoor unit
must be >5°C.
▪ In places where the unit is exposed to direct sunlight for long periods of time.
Extensive UV radiation can damage the unit.
