are added in REVISED EDITION-A.
Outdoor units PU(H)-P3,4VGAA.UK
and PU(H)-P3,4,5,6YGAA.UK
which are connected to those
indoor units are also added in it.
• Please void OC241.
• Refer to the OCT03 REVISED
EDITION-C as for control relation.
This manual does not cover outdoor units.
When serving them, please refer to
the service manual No.OC180
REVISED EDITION-A, OC261 and
this manual in a set.
-The old refrigerant and lubricating oil in the existing piping contains a large amount of chlorine which may cause the lubricating
oil of the new unit to deteriorate.
· Use “low residual oil piping”.
-If there is a large amount of residual oil (hydraulic oil, etc.) inside the piping and joints, deterioration of the lubricating oil will
result.
· Store the piping to be used during installation indoors and keep both ends of the piping sealed until just before
brazing. (Store elbows and other joints in a plastic bag.)
-If dust, dirt, or water enters the refrigerant cycle, deterioration of the oil and compressor trouble may result.
· Use Suniso 4GS or 3GS (small amount) as the lubricating oil to coat flares and flange connection parts.
-The lubricating oil used with the air conditioner is highly hygroscopic. If it is used, water may be mixed in and deterioration
of the lubricating oil may result.
· Use liquid refrigerant to charge the system.
-If gas refrigerant is used to charge the system, the composition of the refrigerant in the cylinder will change and perfor-
mance may drop.
· Do not use a refrigerant other than R407C.
-If another refrigerant (R22, etc.) is used, the chlorine in the refrigerant may cause the lubricating oil to deteriorate.
· Use a vacuum pump with a reverse flow check valve.
-The vacuum pump oil may flow back into the refrigerant cycle and cause the lubricating oil to deteriorate.

5. OUTLET AIR SPEED AND COVERAGE RANGE
w The air coverage range is the value up to the position where the air speed is 0.25m/sec.
When air is blown out horizontally from the unit at the Hi notch position.
The coverage range should be used only as a general guideline since it varies according to the size of the room and the
furniture inside the room.

1-2 Feature of program timer
(1) Daily timer function
Daily timer can be set in 30 minutes units for up to 24 hours.
Each unit can be set for unit ON, unit OFF, or setback operation.
(2) Setback operation
Set back operation is useful for reducing running costs
e.g. At a hotel with a 24-hour system
8:00~23:00 Cooling operation with set temperature at 26°C
23:00~8:00 Setback operation with 2 degrees of setback
As shown in the chart on the right, the set temperature rises 2 degrees
automatically during the setback operation. When the setback operation
ends, normal operation will begin.
(3) Weekly timer function
Daily timer function can apply to each day of the week.
