Installation for indoor unit
Gas pipe
Pipe insulation
The indoor unit allows to connect the gas pipe in two positions. One on the left side of it, this requires
cutting a small plate to be able to make the connection (gure 1). The second connection option is
through the back of the unit. The use of one or another type of connection does not affect the operation
of the equipment, so the decision will be made by the installation itself and under the decision of the
assembler.
The power line does not necessarily have to run parallel to the gas pipe. Make sure that the power line is
free of tension at the time of connection.
1. Bond the connection lines of the indoor and outdoor
unit with insulating tape (preferably), as indicated in the
drawing. Then cover the pipes with an insulating material
that complies with current regulations, and that prevents
condensation.
2. Avoid siphons in the connection pipe between indoor
and outdoor unit.
Install the connection pipe
1. Remove the protection element and lead the
gas line to the connector of the indoor unit. Lightly
screw on the nut with your hands.
2. Connecting the pipe to the indoor unit. Align
the pipe and snug the nut by turning it nger tight.
Then, with a xed wrench, hold the xed nut of
the indoor unit, with a dynamometric wrench turn
the loose nut until obtaining the necessary Nm,
indicated in the attached table.
