INSTALLATION INSTRUCTIONS
INFORMATION FOR THE PERSON IN CHARGE OF INSTALLATION (ELECTRICAL) WORK AND SERVICING
Safety Precautions
● Read these Safety Precautions before beginning installation or electrical work, and
perform the work only in the correct manner.
● Precautions in this manual are given in the form of "Warnings" or "Cautions." Both types
of precautions contain important information related to your safety, the safety of users,
and the correct operation, installation, or maintenance of the air conditioning system. Be
sure to carefully observe all relevant precautions.
This symbol refers to a hazard or unsafe practice which can result
in severe personal injury or death.
This symbol refers to a hazard or unsafe practice which can result
CAUTION
in personal injury or product or property damage.
When installation work is completed, perform a test run and check that no trouble occurs.
Also be sure to explain the methods for using the product to the customer, based on the
contents of the Operation Manual. In addition, request that the customer keep and
conveniently store the "Information for the Person in Charge of Installation (Electrical) Work
and Servicing" together with the Operation Manual.
● Request installation and electrical work only from the dealer or a qualified air
conditioning specialist.
Attempting to carry out installation work on your own, and doing so incorrectly, may
result in electrical shock, fire, or other hazards.
● Installation procedures must be performed correctly, carefully following the instructions
in this document.
Failure to do so may result in electrical shock, fire, or other hazards.
● Electrical work must be performed by a qualified electrician. It must be performed in
accordance with technical standards related to electrical equipment, interior wiring
regulations, local codes, and the contents of these instructions. Be sure to use a
dedicated power supply circuit.
Insufficient power circuit capacity or improper electrical work may result in electrical
shock or fire.
● Use only the designated cables for wiring, and connect them securely. Fasten cables so
that no external force is applied to the terminal connections.
Insufficient connections or cable fastening may result in heat generation, fire, or other
hazards.
CAUTION
● Depending on the installation location, it may be necessary to install an earth leakage
breaker. Failure to do so may result in electrical shock or fire.
● Do not install in kitchens, workshops, or other locations where there is oil mist in the air.
● Do not install next to windows or in other locations exposed to direct sunlight or in direct
contact with outside air.
● Do not install near an elevator, automatic door, industrial sewing machine, or other
devices that can be expected to produce electrical noise.

Installing the Schedule Timer
<Note 1> Avoid twisting the inter-unit control wiring or the input/output wiring together with
power or other wiring, and avoid running them in the same metal conduit. Doing
so can cause malfunction.
<Note 2> Install the schedule timer at a location away from any sources of electrical noise.
<Note 3> Install a noise filter or take other appropriate action if electrical noise affects the
power supply circuit of the unit.

(1) Open the panel on the schedule timer unit. Insert a standard (flathead) screwdriver or
similar tool into the notches on the bottom of the schedule timer unit to open and
remove the back case.
(2) Use the 2 supplied M4 small screws and install the schedule timer back case onto the
switch box. Before installing, use a screwdriver or similar tool to press on and open the
screw holes that correspond to the JIS box that is used.
When fastening the case, use spacers and do not tighten the screws too much. If the
schedule timer does not fit tightly against the wall, cut the spacers as required to make
adjustments.
(3) Connect the supplied power wire (2-core) and inter-unit control wire (3-core) to the
schedule timer unit.

(4) Align the schedule timer unit with the tabs on the back case and press to install it.
Installation of connected schedule timers
● When installing schedule timers (remote controller switches, system controllers, etc.)
onto the wall, use the method shown in Figs. 3 and 4.

* For maintenance reasons, leave a gap of 25 mm or more between the remote controller switch
and schedule timer if they are arranged in parallel above/below each other.
This remote controller has two methods of usage with the weekly timer and the
schedule timer.
The wiring method and switch setting are different in each case.

Wiring specifications (2)
If a 64 system central remote controller (or ON-OFF controller) is not installed (power is
supplied from the indoor unit):
<Note> (1) The only functions of the schedule timer are indoor unit ON/OFF and remote
controller enable/disable operations.
(2) It is required that during installation, a 64 system central remote controller or wired
remote controller be installed next to the schedule timer so that operation mode
and other information can be checked.
(3) If the 64 system central remote controller or other central control device is not
present, the schedule timer cannot be used in combination with a system that does
not utilize remote controllers including high wall (KRT series) systems.
