 It is recommended to purchase the field supply accessories listed in above table.
11.1 Indoor Unit
11.1.1 Select the Best Location
 Install the Tank Unit in indoors with frost free
weather proof location only.
 Must install on a flat horizontal and solid hard
surface.
 There should not be any heat source or steam
near the Tank Unit.
 A place where air circulation in the room is good.
 A place where drainage can be easily done (e.g.
Utility room).
 A place where Tank Unit’s operation noise will not
cause discomfort to the user.
 A place where Tank Unit is far from door way.
 A place where accessible for maintenance.
 Ensure to keep minimum distance of spaces as
illustrated below from wall, ceiling, or other
obstacles.
 A place where flammable gas leaking might not
occur.
 Secure the Tank Unit to prevent it being knocked
over accidentally or during earthquakes.
Please avoid installations which expose the Tank Unit
to any of the following conditions:
 Extraordinary environment conditions; installation
in frost or exposure to unfavorable weather
conditions.
 Voltage input exceeding the specified voltage.
Required space for installation 11.1.1.1
Transport and Handling 11.1.1.2
 Be careful during transporting the unit so that it is
not damaged by impact.
 Only remove the packaging material once it has
reached it is desired installation location.
 It may need three or more people to carry out the
installation work. The weight of Tank Unit might
cause injury if carried by one person.
 The Tank Unit can be transported either in vertical
or horizontal.
o If it transported in horizontal, make sure Front
of packaging material (printed with “FRONT”)
must facing upwards.
o If it transported in vertical, use the hand holes
on sides, slide and move to the desired
location.
 Fix the Adjustable Feet, if the Tank unit installed
on an uneven surface.
11.1.2 To Drill a Hole in the Wall and
Install a Sleeve of Piping
1 Make a Ø70 mm through hole.
2 Insert the piping sleeve to the hole.
3 Fix the bushing to the sleeve.
4 Cut the sleeve until it extrudes about 15 mm
from the wall.
CAUTION
When the wall is hollow, please be sure to use the sleeve
for tube assembly to prevent dangers caused by mice
biting the connection cable.

Typical Piping Installation
Access to Internal Components
WARNING
This section is for authorized and licensed electrician/water
system installer only. Work behind the front plate secured by
screws must only be carried out under supervision of qualified
contractor, installation engineer or service person.
 Open and Close Top Front Plate
1 Remove the 2 mounting screws of Bottom
Front Plate.
2 Slide it upwards to unhook the Bottom Front
Plate hook.
3 Reverse above steps 1~2 for close it.
Refrigerant Piping Installation
This Tank Unit is designed for combination with
Panasonic Air-to-Water Heat Pump Outdoor Unit. If
Outdoor Unit from other manufacturer are being used
in combination with Panasonic Tank Unit, optimum
operation and reliability of the system is not
guaranteed. Thus warranty cannot be given in such
case.
1 Connect Tank Unit to Air-to-Water Heatpump
Outdoor Unit with correct piping size.

CAUTION
Do not overtighten, overtightening may cause gas leakage.
2 Please make flare after inserting flare nut
(located at joint portion of tube assembly) onto
the copper pipe. (In case of using long piping)
3 Do not use pipe wrench to open refrigerant
piping. Flare nut may be broken and cause
leakage. Use proper spanner or ring wrench.
4 Connect the piping:
o Align the centre of piping and sufficiently
tighten the flare nut with fingers.
o Further tighten the flare nut with torque
wrench in specified torque as stated in
the table.
Cutting and Flaring the
Piping
1 Please cut using pipe cutter and then remove
the burrs.
2 Remove the burrs by using reamer. If burrs is
not removed, gas leakage may be caused.
Turn the piping end down to avoid the metal
powder entering the pipe.
