AMBIENT CONDITIONS AND SITE LOCATION.
The ambient conditions and site location significantly influence the
external unit's output and service life. Unfavourable ambient conditions
or site location can result in a significant reduction in output and even
possible appliance damage.
• Never site the external unit where it is exposed to vapour, volatile oils
(incl. machine oil) or sulphurous gas.
• In areas with a high salt content (e.g. on the coast), advice should be
taken on the protection of the unit's evaporator.
• If snow is expected, take appropriate measures to ensure that the
external unit cannot be covered by snow.
• In cold or frosty areas ensure that the condensate can drain off freely
(e.g. by means of a condensate drain or pan).
• Preferably avoid installing the external unit in locations where it would
be exposed to direct or to other heat sources.
FOUNDATION
• The installation surface must be level, firm and of appropriate load-
bearing capacity. It must be able to bear the weight and absorb the
vibrations of the external unit.
• Wooden bases are unsuitable installation areas.
• Requirements for concrete foundations:
– Thickness of concrete: ≥120mm
– Load-bearing capacity: ≥320 kg
• Length of fixing screws: ≥70 mm (subject to foundation).
INSTALLATION SITE IN GENERAL
• Select an installation site (floor standing or wall mounting (available as
an accessory) installation) where the external unit creates no noise
nuisance for other occupants or the neighbourhood.
• Select an installation site where wiring and pipe work to power source
and hybrid manager can be easily accomplished.
• The external unit produces condensation during the heating
operation. Ensure suitable drainage is provided around the external
unit if such condensation is likely to cause risk of injury or damage.
• It is important that flue products or condensate do not drip onto or
enter the air intake of the external unit. Therefore, never locate the
external unit in immediate proximity or directly below the boiler flue
outlet.
• Recirculation of the discharge air can severely affect the output.
• We recommend a floor standing installation where possible.
WINDY LOCATION
If the external unit is sited on a roof or another site exposed to the wind,
ensure that the air discharge is not directly exposed to strong wind.
Possible preventive measures to safeguard against strong wind:
▶ Direct the air discharge towards the nearest wall. The minimum
clearance must be 1000mm.
Fig. 17 Orientation towards a wall (windy location)
[a] Minimum wall clearance 1000mm
▶ Direct the air discharge at an angle of 90° to the main wind direction
[1].

[1] Main wind direction
If the air discharge is oriented directly against a wall this
may discolour over time.
