WARNING

Always check the gas density

limit for the room in which the

unit is installed.

1-11. Check of Limit Density

When installing an air conditioner in a room, it is necessary

to ensure that even if the refrigerant gas accidentally leaks

out, its density does not exceed the limit level for that room.

1-12. Installing Distribution Joint

CAUTION

Pay special attention to any

location, such as a basement,

etc., where leaking refrigerant can

accumulate, since refrigerant gas

is heavier than air.

(1) Refer to “HOW TO ATTACH DISTRIBUTION JOINT”

enclosed with the optional distribution joint kit

(CZ-P900PH1U, CZ-P224BH1U, CZ-P680BH1U,

CZ-P1350BH1U).

(2) 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 should be at an angle that is greater than

horizontal. If the main tubing is vertical, provide a raised

starting portion for each branch.

[Header joint system]

●

Be sure to solidly weld shut the T-joint end (marked

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.

(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 must be added to that

distribution joint. (When adding the ball valve, locate it

within 1.3 ft. of the distribution joint.)

If a trap or ball valve 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.)
