Installing distribution joint
Refer to “HOW TO ATTACH DISTRIBUTION JOINT”
enclosed with the optional distribution joint kit (APR-
CHRZP680BGB, CHRZP1350BGB, RZP224BGB,
RZP680BGB, RZP1350BGB).
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 must be
added to that distribution joint. (When adding the ball
valve, locate it within 40 cm of the distribution joint.)
(Consult with SANYO separately concerning the
ball valve.)
If a trap or ball valve is not added, do not oper-
ate the system before repairs to a malfunction-
ing unit are completed. (The refrigerant oil sent
through the tubing to the malfunctioning unit
will accumulate and may damage the compres-
sor.)

[Header joint system]
Be sure to solidly weld shut the T-joint end (mark-
ed by “X” in the figure). In addition, pay attention
to the insertion depth of each connected tube so
that the flow of refrigerant within the T-joint is not
impeded.
When using the header joint system, do not make
further branches in the tubing.
Do not use the header joint system on the outdoor
unit side.
When creating a branch using a commercially available
T-joint (header joint system), orient the main tubing so
that it is either horizontal (level) or vertical. In order to
prevent accumulation of refrigerant oil in stopped units,
if the main tubing is horizontal then each branch tubing
length “B” should be at an angle that is greater than
horizontal. If the main tubing is vertical, provide a raised
starting portion for each branch.
When only one indoor unit is connected to the side of “A”,
install part “A” at a positive angle (15-30°) for the field
tubing as shown in the figure.
