Installation - Mitsubishi Electric CLIMAVENETA a-LIFE2 HP 302 Installation, Gebrauch Und Wartung

INSTALLATION: POSITIONING THE UNIT
INSTALLATION MUST BE PERFORMED IN OBSERVANCE OF CURRENT REGULATIONS
• Make sure the unit and its technical specifications match the design or other documents.
• Do not leave any packaging within the reach of children as it is a source of danger.
• Wear suitable personal protective devices before installing the unit. Use suitable equipment to prevent accidents during installation.
• Before proceeding with installation mount any accessories on the unit following the assembly instructions contained in each Kit.
• Decide the installation position. Position the unit on a solid structure that does not generate vibrations and that can withstand the weight of the
machine.
• Install the unit in a position that allows routine and extraordinary maintenance to be carried out with ease !
The installer MUST ensure that the unit is covered by appropriate panelling (false-ceilings, partitions, closing panels, etc.) which act as FIXED PRO-
TECTION for the unit. The protection panels MUST be firmly secured with systems requiring the use of tools to open them (e.g.: screws) in order to
prevent users from accessing dangerous areas such as sharp edges, pointed corners, electrical components, moving fan, etc.. It must be possible
to remove the panels (using a tool!) to allow TOTAL ACCESS to the unit, thus eliminating the risk of having to break/damage structures and panels
(plasterboard, false ceilings, etc.) in the event of extraordinary maintenance and/or replacing the unit.

INSTALLATION

VERTICAL
- Mark the fixing holes.
- Drill holes in the wall (at least 2 points).
- Insert screw anchors of a suitable shape and size for the weight of the
units and the type of wall without fully tightening them.
- Attach the fancoil unit using the slots in the rear.
- Tighten the screws.
Make sure the wall is perfectly level. If not, insert
anti-vibration sponges.

- Mark the fixing holes.
- Drill holes in the ceiling (in at least 4 points).
- Insert screw anchors of a suitable shape and size for the weight of the
units and the type of ceiling without fully tightening them.
- Attach the fancoil unit using the slots in the rear.
- Tighten the screws.
Insert anti-vibration material of different thicknesses
between the fancoil unit and the ceiling so as to assure a
slope of 3% to allow condensate to drain.
Attention: Always use a wrench and counter-wrench to connect the
coil to the piping.
▪ Connect to the water supply.
▪ Install on-off valves (MIN 1/2") to isolate the coil from the rest of the circuit in case
extraordinary maintenance is performed. Connect the inlet to a ball valve and the
outlet to a balancing or lockshield valve (or install 2 ball valves).
▪ Insert a vent valve at the top and a drain valve at the bottom.
▪ The heat exchange coils for water are tested to a pressure of 3 MPa (30 bar) and
can therefore operate up to a maximum pressure of 1,5 MPa (15 bar).
▪ Suitably bracket the pipes to the outside of the unit to prevent them from weighing
down on the coil.
Install anti-freeze devices. For installation in areas with particularly cold
climates, empty the water circuit if the system is not expected to be used for
a long time.
