Daikin R32 Split Series Manual de instalación
CAUTION
• When connecting the connection wire to the terminal block using a single core
wire, be sure to perform curling.
Problems with the installation may cause heat and fire.
1) Remove the front grille. (Refer to "2. Removing and installing
the front grille" on page 10.)
2) Remove the conduit mounting plate and then secure the
conduit to the conduit mounting plate with the lock nut, as
shown in the illustration.
3) Strip wire ends (3/4 inch (20mm)).
4) Match wire colors with terminal numbers on the indoor and
outdoor unit's terminal blocks and firmly secure the wires in the
corresponding terminals with the screws.
5) Connect the ground wires to the corresponding terminals.
6) Pull the wires lightly to make sure they are securely connected.
7) In case of connecting to an adapter system, run the remote
controller cable and attach the S21.
(Refer to "4. When connecting to an HA system" on page 11.)
8) Attach the conduit mounting plate.
9) Shape the wires so that the service lid fits securely.
10) Attach the front grille. (Refer to "2. Removing and installing the front
grille" on page 10.)
11) Take care to ensure that all wiring between the indoor unit and the outdoor unit
has a consistent connection. Any splices can cause communication errors.

Drain piping

1) Connect the drain hose, as described on the right.
• Avoid placing the end of the drain hose in a drainage location that could
cause bad odors or corrosive gas to flow backward into the outlet.
• The drainage water may change color due to bacteria or other
organisms. Place in a location where the flow of drainage water will not
cause a problem.
• Minimize the number of bends in the drain hose as much as possible.
If bending the drain hose, bend it gently.
2) Remove the air filters and transfer some water to the indoor heat
exchanger by pouring water into the drain pan.
3) Make sure that water flows out of the drain hose.
4) If drain hose extension or embedded drain piping is required, use
appropriate parts that match the hose front end.
Figure of hose front end
• When drain hose requires extension, obtain an extension
hose with an inner diameter of 5/8 inch (16mm).
Be sure to thermally insulate the indoor section of the
extension hose.
• When connecting a rigid polyvinyl chloride pipe
(nominal diameter 1/2 inch (13mm)) directly to
the drain hose attached to the indoor unit as with
embedded piping work, use any commercially
available drain socket (nominal diameter 1/2 inch
(13mm)) as a joint.
