5 Transport
Units of the EcoTouch Ai1 Air series are delivered ready-to-connect with
separate metal cladding. For easy transport the heat pump will be supplied
in three packaging: hot water tank, heat pump unit and housing.
Since the unit weighs 120 kg or more, at least two people are required for
transport.
The devices are mounted above each other at the installation site. During
transport it must be ensured that appropriate means of transport are used
(lift truck, transport rollers, handcart).
Heat pump (outdoor unit) must be transported upright!
Transport in tilted position (45°) is permitted only temporarily during insertion. Horizontal transport results in oil displacement in compressor and can
cause damage during start-up.
After carton is removed or opened it is not permitted to tilt the unit by applying pressure to the pipelines or housing enclosure; this could result in
bent housing parts and pipelines.

6 Installation and connection
6.1 Installation and connection of indoor unit
To make hydraulic connections, you must use the supplied material (connecting lines and gaskets).
During assembly of connecting lines, use an according tool as brace to
prevent damage to the heat distribution station.
Installation of heat distribution station / storage tank must be performed at
a flat and horizontal surface.
Wall clearance in front: at least 1000 mm.
Because all connections are on the rear panel, choose a installation dis-
tance from the wall (rear, right side, left side), which is also ensures access in case of repair.
Recommendation:
Wall clearance left, right and on top must be at least 400 mm.
Wall clearance in rear must be at least 200 mm.
Wall clearance in front: at least 1.000 mm.
