▪ ALWAYS make sure to secure the stop valve with a spanner, then

loosen or tighten the flare nut with a torque wrench. Do NOT place
the  spanner  on  the  stem  cap,  as  this  could  cause  a  refrigerant
leak.

▪ When  it  is  expected  that  the  operating  pressure  will  be  low  (e.g.

when  cooling  will  be  performed  while  the  outside  air  temperature
is  low),  sufficiently  seal  the  flare  nut  in  the  stop  valve  on  the  gas
line with silicon sealant to prevent freezing.

Silicon sealant; make sure there is no gap.

To open/close the stop valve

1

Remove the stop valve cover.

2

Insert  a  hexagon  wrench  (liquid  side:  4  mm,  gas  side:  6  mm)
into the valve stem and turn the valve stem:

Counterclockwise to open.
Clockwise to close.

3

When  the  stop  valve  CANNOT  be  turned  any  further,  stop
turning.

4

Install the stop valve cover.

Result: 

The valve is now open/closed.

To handle the stem cap

▪ The  stem  cap  is  sealed  where  indicated  with  the  arrow.  Do  NOT

damage it.

▪ After handling the stop valve, tighten the stem cap, and check for

refrigerant leaks.

To handle the service cap

▪ ALWAYS use a charge hose equipped with a valve depressor pin,

since the service port is a Schrader type valve.

▪ After  handling  the  service  port,  tighten  the  service  port  cap,  and

check for refrigerant leaks.

flat head screwdriver and a hammer.

▪ Optionally, cut out the slits (b) with a metal saw.

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.
