Installation
General notes
Safety areas and functional distances
Positioning
Consider these elements during posi-
tioning:

Technical spaces requested by the
unit

Electrical connections

Water connections

Functional clearances

The optional vibration dampers influ-
ence the overall height
Functional clearances
Functional clearances have the pur-
pose of:

guaranteeing good unit operation

allowing maintenance operations

safeguarding authorised operators
and exposed persons.

respecting the functional clearances
indicated
Positioning
Units are designed to be installed:

Outdoors

in permanent and flat position.

Units may be installed on the ground
or on the roof provided that sufficient
ventilation is guaranteed.
If the unit is installed on a roof, the
roof must be sturdy enough to with-
stand the weight of the unit and the
weight of maintenance personnel.
Limit the transmission of vibrations:

use anti-vibration devices or neo-
prene strips on the unit support
points

install flexible joints on the hydraulic
connections

The unit must be level
Pressure relief valve gas side
The installer is responsible for
evaluating the opportunity of installing
drain pipes in compliance with the
local regulations in force (EN 378).
If ducted, the valves must be resized
according to EN13136
Condensate
When a heat pump is in operation it
produces a considerable amount of
water due to the defrosting cycles of
the external coil.
The condensate must be disposed of
in order to avoid damaging people
and things.
Installation criteria:
Customer approval

position accessible safely

technical spaces requested by the
unit

spaces for the air intake/exhaust

max. distance allowed by the electri-
cal connections

install the unit raised from the
ground

verify unit weight and bearing point
capacity

verify that all bearing points are
aligned and levelled

condensate water draining

consider the maximum possible
snow level

avoid places that can be subject to
floods

Protect the unit with a suitable fence
in order to avoid access to unauthor-
ised personnel (children, vandals,
etc.)
A correct circulation of the air is man-
datory to guarantee the good unit
operating.
Avoid therefore:

obstacles to the airflow

ventilation difficulties

leaves or other foreign bodies that
can obstruct the air coil

winds that hinder or favour airflow

sources of heat or pollution close to
the unit (chimneys, extractors etc..)

Stratification (cold air that stagnates
at the bottom)

recirculation (expelled air that is
sucked in again)

positioning below ground level, near
very high walls, underneath roofs or
in corners, which can give rise to
stratification or recirculation phenom-
ena.

Disregarding the previous indica-
tions may affect energy efficiency or
lead to blocks due to HIGH PRES-
SURE (in summer) or LOW PRES-
SURE (in winter)..
Structure for installation.

Both steel and concrete bases may
be suitable.

The base must have a height of at
least 300 mm from the ground so as
to provide sufficient room to install
hydraulic pipes and electrical con-
nections.

Verify that the base and bearing
points are level.

Envisage a drain for the condensa-
tion that may form on the heat ex-
changer when the unit functions as
a heater.
The drain must direct the condensa-
tion away from roads and pave-
ments, especially in places where
condensation might freeze.

Make sure that the installation base
is separate from the buildings, as
the noise and vibrations may propa-
gate.

Fix the unit to the foundation using
the installation holes on the base of
the unit.
Prevent the accumulation of snow.
Batteries and fans must always be
kept free from obstacles, accumulated
leaves, snow, etc.
If the unit is installed where it might
snow:

do not install the unit under trees or
roofs that may accumulate snow

envisage a base of a suitable height
for a possible accumulation of snow.

arrange for a roof that can protect
the fans from accumulations of
snow.

the roof must not cause short cir-
cuits between the air expelled from
the fans and that suctioned by the
batteries,.
Otherwise the accumulated snow will
block the airflow and may cause prob-
lems to the equipment.
