NOTICE

Precautions when making knockout holes:

▪ Avoid damaging the casing and underlying piping.
▪ After  making  the  knockout  holes,  we  recommend  to

remove  the  burrs  and  paint  the  edges  and  areas

around the edges using repair paint to prevent rusting.

▪ When  passing  electrical  wiring  through  the  knockout

holes,  wrap  the  wiring  with  protective  tape  to  prevent

damage.

Do the following:

▪ Connect the liquid pipe (a) to the liquid stop valve.

▪ Connect the gas pipe (b) to the gas stop valve.

Do the following:

▪ Insulate the liquid piping (a) and the gas piping (b).

▪ Wind  heat  insulation  around  the  curves,  and  then  cover  it

with vinyl tape (c).

▪ Make  sure  the  field  piping  does  not  touch  any  compressor

components.

▪ Seal the insulation ends (sealant etc.) (d).

▪ Wrap the field piping with vinyl tape (e) to protect it against

sharp edges

If the outdoor unit is installed above the indoor unit, cover the

stop  valves  (f,  see  above)  with  sealing  material  to  prevent

condensed water on the stop valves from moving to the indoor

unit.

NOTICE

Any exposed piping might cause condensation.

6

Reattach the service cover and the piping intake plate.

7

Seal all gaps (example: a) to prevent snow and small animals

from entering the system.

NOTICE

Do not block the air vents. This could affect air circulation

inside the unit.

WARNING

Provide adequate measures to prevent that the unit can be

used  as  a  shelter  by  small  animals.  Small  animals  that

make contact with electrical parts can cause malfunctions,

smoke or fire.

NOTICE

Make  sure  to  open  the  stop  valves  after  installing  the

refrigerant piping and performing vacuum drying. Running

the  system  with  the  stop  valves  closed  may  break  the

compressor.
