Connection dimensions WPL 5 N hydraulic module in mm
Installation conditions
Hydraulic module
the room in which the appliance is to
be installed must meet the following
conditions:
 Free from the risk of frost
 load-bearing floor (wet weight
of the full DHw cylinder approx.
400 kg)
 level, even and firm base
 the installation room must not
be subject to a risk of explosions
arising from dust, gases or
vapours

when installing the appliance in
a boiler room together with other
heating equipment, ensure that
the operation of the other heating
appliances will not be impaired
Heat pump module
observe the following when installing
the heat pump module:
 Maintain the minimum clearances
to the building specified in the
diagram
 the heat pump module must be
level (horizontal)

the wind from the predominant
wind direction must not blow
directly onto the fan

when selecting the installation
location remember that the
appliance generates noise and
cold draughts during operation
 Maintain as small a clearance as
possible between the heat pump
module and the hydraulic module
to keep line losses to a minimum
 in winter, the heat pump module
must not be covered with snow
or be submerged in case of heavy
rainfall

ensure access to the power supply
(plastic cover)

Condensate must be able to freely
drain underneath the appliance,
even during frosty weather
