The whole system should be thoroughly flushed to remove
any debris that may be in the supply pipework to the HIU and
to the domestic hot water pipework in the apartment before
connecting the HIU.
Fix the HIU to the wall
N.B.
: the wall anchors (not supplied) can only guarantee
effective support if inserted correctly (in accordance with
good technical practice) into walls built using solid or
semi-solid bricks. If working with walls built using perforated
bricks or blocks, mobile dividing panels or any masonry walls
other than those indicated, a preliminary static test must be
carried out on the support system.

Installation
The 201-2001 HIU is designed for installation in a sheltered
domestic environment (or similar), therefore cannot be installed
or used outdoors, i.e. in areas directly exposed to atmospheric
agents. Outdoor installation may cause malfunctioning and
hazards.
If the device is enclosed inside or between cabinets, sufficient
space must be provided for routine maintenance procedures. It is
recommended that electrical devices are NOT placed underneath
the HIU, as they may be damaged in the event of leakage from
any hydraulic component of connection.
If this advice is not heeded, the manufacturer cannot be held
responsible for any resulting damage.
In the event of a malfunction, fault or incorrect operation, the
device should be deactivated; contact a qualified technician for
assistance.
Preparation
After establishing the position where the HIU will be installed,
perform the following operations:
•
Mark the holes required for securing the HIU to the wall.
•
Mark the position of the water pipe connections.
Check the measurements again before installing pipework and
electrical cables.
