CAUTION
•
Over-tightening the flare nut may break it and/or cause the refrigerant to leak.
Not recommendable but in case of emergency
You must use a torque wrench but if you are obliged to install the unit without a torque wrench, you may
follow the installation method mentioned below.
After the work is finished, make sure to check that there is no gas leak.
When you keep on tightening the flare nut with a spanner, there is a point where the tightening torque
suddenly increases. From that position, further tighten the flare nut the angle shown below:
Unless followed the tightening instruction (it is loose tightening), it will lead to the refrigerant leakage (slow
leak) and the device malfunction (it does not sufficiently cool or heat).
CAUTION
For local insulation, be sure to insulate local piping all the way into the pipe connections inside the
machine.
Exposed piping may cause condensation or burns on contact.
•
Make absolutely sure to execute heat insulation works on the pipe-connecting section after checking gas
leakage by thoroughly studying the following figure and using the attached heat insulating materials for
fitting (4) and (5). (Fasten both ends with the clamps (8).)
(Refer to Fig. 8)
•
Wrap the middle sealing material (7) around the insulation for fitting (4) and (5) for the joint (flare nut part).
•
Make sure that the joint of the insulation for fitting (4) and (5) for the joint on the liquid piping and gas piping
side faces upward.
