CAUTION
Pay special attention to any location, such as a basement,
etc. where leaking refrigerant can accumlate, since
refrigerant gas is heavier than air.
1-11. Installing Distribution Joint
(1) Refer to “HOW TO ATTACH DISTRIBUTION JOINT”
enclosed with the optional distribution joint kit
(CZ-P160BK2).
(2) In order to prevent accumulation of refrigerant oil in
stopped units, if the main tubing is horizontal then each
branch tubing length should be at an angle that is greater
than horizontal. If the main tubing is vertical, provide a
raised starting portion for each branch.
(3) If there are height differences between indoor units or if
branch tubing that follows a distribution joint is connected
to only 1 unit, a trap or ball valve (field supply) must be
added to that distribution joint. (When adding the ball
valve, locate it within 40 cm of the distribution joint.)
If a trap or ball valve (field supply) is not added, do not
operate the system before repairs to a malfunctioning unit
are completed. (The refrigerant oil sent through the tubing to
the malfunctioning unit will accumulate and may damage the
compressor.)
