Piping Insulation - Panasonic CS-E12SD3UAW Installation Manual

Piping Insulation

1 Please carry out insulation at pipe connection portion as mentioned in Indoor/Outdoor Unit Installation
Diagram. Please wrap the insulated piping end to prevent water from going inside the piping.
2 If drain hose or connecting piping is in the room (where dew may form), please increase the insulation by
using POLY-E FOAM with thickness 1/4" (6 mm) or above.
Switching the High State Switch (SW2)
To increase the air volume, open the control box and on the control board, switch the FAN switch (SW2) to "HI".
See the diagram for "Connecting the Indoor/Outdoor Connection Cable".
Note: Enabling Long-range Remote Control
To maintain EMC emission limits, cabling interconnecting the HA terminal and subsequent opto-coupler, must be
no more than 6.2 ft (1.9 m) length.
Loop four turns of this cable through a suitable small EMC ferrite toroid, and protect with a short length of large
diameter heat-shrink tube.
There is no similar length limit for cable following on from the opto-coupler isolation.
DISPOSAL OF OUTDOOR UNIT DRAIN WATER
If a drain elbow is used, the unit should be placed
on a stand which is taller than 1 3/16" (30 mm).
If the unit is used in an area where temperature
falls below 32°F (0°C) for 2 or 3 days in
succession, it is recommended not to use a drain
elbow, for the drain water freezes and the fan will
not rotate.
CHECK THE DRAINAGE
Check after connecting the power supply.
Pour approximately 600 cc of water into the drain
pan of the main unit using a squeeze bottle, etc.
Press the drain test run switch on the control
board in the control box to start the drain motor
and check whether the water drains normally.
(The drain motor operates for approximately
5 minutes and then stops automatically.)
(See the diagram for "Connecting the
Indoor/Outdoor Connection Cable".)
Install the hose at an angle so that the water smoothly flows out.
