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.
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:
After the work is finished, make sure to check that there is no gas leak.
•
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 (8) and (9). (Fasten both ends with the clamps (4).)
(Refer to Fig. 16)
•
Wrap the sealing pad (11) only around the insulation for the joints on the gas piping side.
(Refer to Fig. 16)
CAUTION
For field insulation, be sure to insulate field piping all the way into the pipe connections inside the machine.
Exposed piping may cause condensation or burns on contact.
