Avoid:

Installation Location

•

We recommend that this air conditioner be installed properly by
qualified installation technicians in accordance with the Installation
Instructions provided with the unit.

•

Before installation, check that the voltage of the electric supply in your
home or office is the same as the voltage shown on the nameplate.

•

Do not install this air conditioner where there are fumes or flammable
gases, or in an extremely humid space such as a greenhouse.

•

Do not install the air conditioner where excessively high heat­generating objects are placed.

•

To protect the air conditioner from heavy corrosion, avoid installing the
outdoor unit where salty sea water can splash directly onto it or in
sulphurous air near a spa.

•

The unit may malfunction when the receiver in the indoor unit is
exposed to the inverter lamp light.

Electrical Requirements

1. All wiring must conform to the local electrical codes. Consult your

dealer or a qualified electrician for details.

2. Each unit must be properly grounded with a ground (or earth) wire or

through the supply wiring.

3. Wiring must be done by a qualified electrician.

•

Power supply: 60 Hz, single-phase, 230/208 volts.

Power mains

CAUTION

To warm up the system, the power mains must be

ON

turned on at least five (5) hours before operation.
Leave the power mains ON unless you will not be
using this appliance for an extended period.

For ceiling-mounted and recessed-type indoor units, the flaps move for one
minute when the power is supplied to the unit. This is not a malfunction.

Safety Instructions

•

Read this Instruction Manual carefully before using this air conditioner.
If you still have any difficulties or problems, consult your dealer for
help.

•

This air conditioner is designed to give you comfortable room
conditions. Use this only for its intended purpose as described in this
Instruction Manual.

•

Never touch the unit with wet hands.

•

Never use or store gasoline or other flammable vapor or liquid near the
air conditioner — it is very dangerous.

•

This air conditioner has no ventilator for intaking fresh air from
outdoors. You must open doors or windows frequently when you use
gas or oil heating appliances in the same room, which consume a lot of
oxygen from the air. Otherwise there is a risk of suffocation in extreme
cases.

CAUTION

•

Do not turn the air conditioner on and off from the power mains switch.
Use the ON/OFF operation button.

•

Do not stick anything into the air outlet of the outdoor unit. This is
dangerous because the fan is rotating at high speed.

•

Do not let children play with the air conditioner.

•

Do not cool the room too much if babies or invalids are present.

ADDRESS switch•Change the address switch to prevent mixing of signals from remote control

units when two Sanyo air conditioners are installed next to each other.
Normally, the remote control address switch is set to A. For the second
indoor unit, both addresses of the remote control unit and the indoor unit
must be changed. The second remote control unit address must be changed
to B by breaking off the tab ”A“. And the second indoor unit address must
be changed from 1 to 2 by switching the slide switch in the indoor unit. For
more information, please contact the dealer where you made the purchase.

•

Normally, the tabs on the remote control unit should not be bent.

SENSOR button When you press this button (use a small-tipped object such as a ballpoint

pen), the mark will appear at the display. And the room temperature is
detected by the sensor which is built into the indoor unit and the air
conditioner is controlled accordingly.

NOTE If the remote control is located near a heat source, such as a space heater or

in direct sunlight, press the SENSOR button to switch to the sensor on the
indoor unit.

NOTE The remote control unit sends the temperature signal to the air conditioner regularly at five minute intervals.

If the signal from the remote control unit stops for more than ten minutes due to the loss of the remote
control unit or other trouble, the air conditioner will switch to the temperature sensor which is built into
the indoor unit and control the room temperature. In these cases, the temperature around the remote
control unit may differ from the temperature detected at the air conditioner’s position.

Block the air intake and outlet of the unit. If either is obstructed, the
unit will not work well, and may be damaged.

other openings closed.
