Finishing The Indoor Unit Installation - Friedrich MD12Y3JM Manual De Instrucciones

Wrap the insulation material around the
connecting portion.
1. Overlap the connection pipe insulation and the
indoor unit pipe heat insulation material. Bind
them together with vinyl tape so that there is no
gap.
2. Wrap the area which accommodates the rear
piping housing section with vinyl tape.
3. Bundle the piping and drain hose together by
wrapping them with vinyl tape over the range
within which they fit into the rear piping housing
section.
Reroute the pipings and the drain hose across
the back of the chassis.

Finishing the indoor unit installation

1. Mount the tubing holder in the original positon.
2. Ensure that the hooks are properly seated on the
installation plate by moving it left and right.
3. Press the lower left and right sides of the unit
against the installation plate until the hooks en-
gage into their slots (clicking sound).
4. Finish the assembly by screwing the unit to the
installation plate by using two pieces of type "C"
screws. And assemble a chassis cover.
If the split type Indoor unit is installed in a wall having hole or opening near by or back side of the
unit, then the air from other side of the wall can come inside the condition space through that hole
/ opening. That air can cause unwanted dew / water droplet formation when it comes in contact
with body of the indoor unit. So all hole or opening on the wall must be blocked very well to avoid
water dropping from the body of the unit.
