REFRIGERANT PIPING WORK
7-1
GENERAL INSTRUCTIONS
• For refrigerant piping of outdoor units, see the installation man-
ual attached to the outdoor unit.
• Before refrigerant piping work, check which type of refriger-
ant is used. Proper operation is not possible if the types of
refrigerant are not the same.
• The outdoor unit is charged with refrigerant.
DANGER
• Refrigerant gas may produce toxic gas if it comes in contact
with fire such as from a fan, heater, stove or cooking device.
Exposure to this gas could result in severe injury or death.
NOTE
• Use a pipe cutter and flare suitable for the type of refriger-
ant.
• To prevent dust, moisture or other foreign matter from infiltrat-
ing the tube, either pinch the end or cover it with tape.
• Do not allow anything other than the designated refrigerant to
get mixed into the refrigerant circuit, such as air. If any refrig-
erant gas leaks while working on the unit, ventilate the
room immediately. .
7-2
Connecting the refrigerant piping
• When connecting the flare nut, coat the flare both inside
and outside with ester
oil or ether oil and initially tighten by
hand 3 or 4 turns before tightening firmly.
• To prevent flare nut cracking and gas leaks, be sure to use
both a spanner and torque wrench together, as shown in the
drawing below, when connecting or disconnecting pipes to/
from the unit.
