How To Install The Outdoor Unit - Panasonic U-4LE1E5 Installation Instructions Manual

3. HOW TO INSTALL THE OUTDOOR UNIT

3-1. Installing the Outdoor Unit
●
Use concrete or a similar material to create the base, and
ensure good drainage.
●
Ordinarily, ensure a base height of 5 cm or more. If a drain
pipe is used, or for use in cold-weather regions, ensure a
height of 15 cm or more at the feet on both sides of the unit.
(In this case, leave clearance below the unit for the drain
pipe, and to prevent freezing of drainage water in cold-
weather regions.)
●
Refer to Fig. 3-1 for the anchor bolt dimensions.
●
Be sure to anchor the feet with anchor bolts (M10). In
addition, use anchoring washers on the top side. (Use large
square 32 × 32 SUS washers with JIS nominal diameter of
10.) (Field supply)

3-2. Drainage Work
Follow the procedure below to ensure adequate draining for the
outdoor unit.
●
For the drain port dimensions, refer to Fig. 3-1.
●
Ensure a base height of 15 cm or more at the feet on both
sides of the unit.
●
When using a drain pipe, install the drain socket (field
supply) onto the drain port. Seal the other drain port with the
rubber cap supplied with the drain socket.
●
For details, refer to the instruction manual of the drain socket
(field supply).
●
After completing the installation work of the drain socket,
make sure that the water does not leak from any part of
connection.

3-3. Routing the Tubing and Wiring
●
The tubing and wiring can be extended out in 4 directions
(front, rear, right, and down):
●
The service valves are housed inside the unit. To access
them, remove the inspection panel. (To remove the
inspection panel, remove the 3 screws, then slide the panel
downward and pull it toward you.)
(1) If the routing direction is through the front, rear, or right,
use a nipper or similar tool to cut out the knockout holes for
the inter-unit control wiring outlet, power wiring outlet, and
tubing outlet from the appropriate covers A and B.
When routing the wiring, be sure to attach each supplied
plastic bar to the edges around the wiring outlet holes in
order to protect the wiring from scratches by the cutting
burr.
(2) If the routing direction is down, use a nipper or similar tool
to cut out the lower flange from cover A.

* When not using a conduit material or existing materials,
measure and cut the supplied plastic bar according to the size
of the wiring outlet hole. Then attach the plastic bar to the edges
around the hole. Use sealing putty to seal off the hole to prevent
the dust and insects from entering the wiring outlet holes.
CAUTION
● Route the tubing so that it does not contact the
compressor, panel, or other parts inside the unit.
Increased noise will result if the tubing contacts these
parts.
● When routing the tubing, use a tube bender to bend the
tubes.
4. ELECTRICAL WIRING
4-1. General Precautions on Wiring
(1) Before wiring, confirm the rated voltage of the unit as
shown on its nameplate, then carry out the wiring closely
following the wiring diagram.
(2) Provide a power outlet to be used exclusively for each
unit and a power supply disconnect, circuit breaker and
earth leakage breaker for overcurrent protection should be
provided in the exclusive line.
(3) To prevent possible hazards from insulation failure, the unit
must be grounded.
(4) Each wiring connection must be done in accordance with
the wiring system diagram. Wrong wiring may cause the
unit to disorder or become damaged.
(5) Do not allow wiring to touch the refrigerant tubing,
compressor, or any moving parts of the fan.
(6) Unauthorized changes in the internal wiring can be very
dangerous. The manufacturer will accept no responsibility
for any damage or malfunction that occurs as a result of
such unauthorized changes.
(7) Regulations on wire diameters differ from locality to
locality. For field wiring rules, please refer to your LOCAL
ELECTRICAL CODES before beginning.
You must ensure that installation complies with all relevant
rules and regulations.
