(2) Precautions regarding piping work
Caution
•
Apply thermal insulation to all tubing, including branch tubes. Make sure that there are no gaps or
openings in the thermal insulation that may allow moisture to enter. Use thermal insulation that can
withstand a minimum of 120°C for the gas
side (wide tube system), and a minimum of
80°C for the liquid side (narrow tube system).
Failure to do so can result in water leakage
and dripping condensation, leading to wall
discoloration, paddling, etc.
•
Use separate piping for the power cables
and the control cables. If the cables are
passed through the same pipes, the effects
of electrical noise and induction can cause
malfunctions.
(3) Select the gas pipe, liquid pope, blanches(separately sold), and make the necessary preparations for
installation.
•
After cutting the tube, be sure to remove all burrs and finish tubing ends to the
correct surface. (The same must be done for branch tubes (purchased
separately).)
•
When bending tubes, be sure the bend radius is at least 4 times the outer
diameter of the tube.
•
When cutting or bending tubes, be careful not to cause any pinching or blockage
of the tube.
Caution
Prevent foreign substances such as dirt or water from entering the tube by
sealing the end of the tubes with either a cap or with tape. Otherwise, this
can damage the devices and result in malfunction.
