Table of Contents

Applicable models : Slim Multi S Series

Carefully read this section “Always observe for safety”, and securely install the optional parts.
Be sure to observe the cautions described here: They include critical contents for safety.
The following indications show the classification of danger and possible consequences following incorrect installation
- WARNING Incorrect installation could lead to death or serious injury.
- CAUTION Incorrect installation could lead to injury or damage to house and household articles.
After installation, perform a test run and make sure that there is no abnormality, and ask your customer to keep this installation sheet with the instruction manual at all times. Also ask the customer to transfer these manuals to a new user if the user changes.

WARNING
Ask the dealer or specialist for installation.

If installed incorrectly by the user, water leak, electric shock, fire, etc. could result.

Carefully install the panel according to this installation sheet.

Before performing installation (moving) and electrical work
CAUTION

Do not place polyethylene bags in the reach of young children.

Putting them over the head will block breathing passages, which could result in suffocation.

Securely apply heat insulation to the refrigerant pipe so that no condensation occurs.

If heat insulation is inadequate, condensation could on the surface of pipes, and dewdrops could accumulate on the ceiling, floor, or important goods.

If electrical work is necessary, use only specified electric wires adapted to the current capacity.

Securely perform drain piping work according to the installation manual so that no condensation occurs.

If piping work is incorrect, a water leak may occur and the ceiling, furniture, etc. may get wet.

Make sure that all the following parts are in the packing box before performing work:

Note : Procure the following at the local site:

Take care with the following when performing work:

Observe the restrictions in refrigerant piping length and number of installation indoor units that are described in the outdoor unit installation manual.
Use anti-oxidization brazing to connect the 2-branch joint and pipes (6-15).
The 2-branch joint has stoppers: Insert the pipe to be connected in until it stops.
There is no restriction on the installation posture of the 2-branch joint.
Take care that no foreign object, such as dust, enters the pipes during piping connection work.
Use a heat insulator for all refrigerant pipes.

Selecting refrigerant pipe size and using a 2-branch joint

Procure pipes to be connected at the local site.
Determine the sizes of pipes to be connected according to the installation manual of the outdoor unit to be installed.
The 2-branch joint is designed so that all pipes with sizes selected in step 2 can be connected.
Perform connections referring to Fig. 1 and Tables 1-4. Connect each pipe to match the size, appropriately judging the following:
Use without any processing, or Use while connecting pipe.

(heat insulator)

Fit pipe cover (4) to liquid pipe (small) (2) to attach it.
Use heat insulator sealing tape (field supply) to seal the butted portion of the pipe cover (4) (see Fig.2).
Process gas pipe (large) (3) in the same way as liquid pipe (small) (2).
Note 1: Use a heat insulator for all refrigerant pipes (field supply). When using generally available heat insulators, buy a heat-resistant heat insulator (thickness of at least 8 mm (5/16″)).
Note 2: The pipe cover will slightly shrink at high temperatures: Use a heat insulator with a lap margin.
