Installing Indoor Unit - Daikin Air Conditioner Installation Manual

2.
Boring a wall hole and installing wall embedded pipe.
• For walls containing metal frame or metal board, be sure to use a wall
embedded pipe and wall cover in the feed-through hole to prevent
possible heat, electrical shock, or fire.
• Be sure to caulk the gaps around the pipes with caulking material to
prevent water leakage.
1) Bore a feed-through hole of 3-1/8 inch (80mm) in the wall so it has a
down slope toward the outside.
2) Insert a wall pipe into the hole.
3) Insert a wall cover into wall pipe.
4) After completing refrigerant piping, wiring, and drain piping, caulk pipe
hole gap with putty.

3-1. Right-side, right-back, or right-bottom piping.
1) Attach the drain hose to the underside of the refrigerant pipes
with adhesive vinyl tape.
2) Wrap the refrigerant pipes and drain hose together with
insulation tape.
3) Pass the drain hose and refrigerant pipes through the wall
hole, then set the indoor unit on the mounting plate hooks by
using the
4) Open the front panel, then open the service lid. (Rifer to
Installation Tips.)
5) Pass the interconnecting wires from the outdoor unit through
the feed-through wall hole and then through the back of the
indoor unit. Pull them through the front side.
Bend the ends of tie wires upward in advance for easier work.
(If the interconnecting wire ends are to be stripped first, bundle
wire ends with adhesive tape.)
6) Press the indoor unit's bottom panel with both hands to set it
on the mounting plate hooks. Make sure the wires do not catch
on the edge of the indoor unit.
3-2. Left-side, left-back, or left-bottom piping.
1) Attach the drain hose to the underside of the refrigerant pipes
with adhesive vinyl tape.
2) Be sure to connect the drain hose to the drain port in place of
a drain plug.
3) Shape the refrigerant pipe along the pipe path
marking on the mounting plate.
4) Pass drain hose and refrigerant pipes through
the wall hole, then set the indoor unit on
mounting plate hooks, using the
the top of indoor unit as a guide.
5) Pull in the interconnecting wires.
6) Connect the inter-unit piping.
7) Wrap the refrigerant pipes and drain hose together with
insulation tape as right figure, in case of setting the drain hose
through the back of the indoor unit.
8) While exercising care so that the interconnecting wires do not catch
indoor unit, press the bottom edge of indoor unit with both hands until
it is firmly caught by the mounting plate hooks. Secure indoor unit to
the mounting plate with the screws (3/16" × 1/2"L (M4 × 12mm)).
