1

Push  the  drain  hose  as  far  as  possible  over  the  drain  pipe
connection.

2

Tighten  the  metal  clamp  at  the  base  of  the  drain  socket.  Wrap
the  end  of  the  metal  clamp  with  vinyl  tape  or  bend  the  end
inwards to avoid damaging the sealing pad.

3

Check for water leaks (see 

"To check for water leaks"

 [

 17]).

4

Wind  the  large  sealing  pad  (=  insulation)  around  the  metal
clamp  and  drain  hose,  and  fix  it  with  tie  wraps.  Start  wrapping
from the tightened part of the metal clamp so that the end of the
metal clamp is wrapped twice.

5

Connect the drain piping to the drain hose.

To check for water leaks

Make  sure  the  unit  is  level  in  accordance  with  the  instructions  in

"12.2.1  Guidelines  when  installing  the  indoor  unit"

  [

  14].  Gradually

pour approximately 1 l of water through the air discharge outlet, and
check for leaks.

13.1.1

Refrigerant piping requirements

CAUTION

Piping MUST be installed according to instructions given in

"13  Piping  installation"

  [

4

  17].  Only  mechanical  joints  (e.g.

braze+flare connections) that are compliant with the latest
version of ISO14903 can be used.

NOTICE

The  piping  and  other  pressure-containing  parts  shall  be
suitable  for  refrigerant.  Use  phosphoric  acid  deoxidised
seamless copper for refrigerant piping.

▪ Foreign materials inside pipes (including oils for fabrication) must

be ≤30 mg/10 m.

Refrigerant piping diameter

For  piping  connection  of  the  indoor  unit,  use  the  following  piping
