Bosch Wall Mounted Ductless Split Air Conditioner / Heat Pump IDU-ODU - BTC 769102301 A (11.2022)

WARNING: ELECTRICAL HAZARD

For all electrical work, follow all local and national wiring

standards, regulations, and the Installation Manual.

The power supply to the outdoor unit requires a service

disconnect at the unit. Only use a dedicated circuit. Never

share a power source connected to this system. Insufficient

electrical capacity or defects in electrical work can cause

electrical shock or fire.

For all electrical work, use the specified cables. Connect

cables tightly, and clamp them securely to prevent external

forces from damaging the terminal. Improper electrical

connections can overheat and cause fire, and may also

cause shock.

All wiring must be properly arranged to ensure that the

control board cover can close properly. If the control board

cover is not closed properly, it can lead to corrosion and

cause the connection points on the terminal to heat up,

catch fire, or cause electrical shock.

In certain functional environments, such as kitchens, server

rooms, etc., the use of specially designed air-conditioning

units is highly recommended.

If the power supply cord is damaged, it must be replaced

by the manufacturer, its service agent or similarly qualified

persons such as a licensed electrician in order to avoid a

hazard.

The product must be properly grounded at the time of

installation, or electrical shock may occur.

CAUTION: BURN HAZARD

For units that have an auxiliary electric heater, do not

install the unit within 1 meter (3 feet) of any combustible

materials.

Do not install the unit in a location that may be exposed

to combustible gas leaks. If combustible gas accumulates

around the unit, it may cause fire.

Do not operate your air conditioner in a wet room such as a

bathroom or laundry room. Too much exposure to water can

cause electrical components to short circuit.

NOTICE: PROPERTY DAMAGE

Install condensate drainage piping according to the

instructions in this manual. Improper condensate drainage

may cause water damage to your home and property.

CAUTION: CONTAINS REFRIGERANT

This air-conditioning unit contains fluorinated gases. For

specific information on the type of gas and the amount,

please refer to the relevant label on the outdoor unit itself.

Installation, service, maintenance and repair of this unit

must be performed by a certified technician.

Product removal and recycling must be performed by a

certified technician.

If the system has a leak-detection system installed, it must

be checked for leaks at least every 12 months.

When the unit is checked for leaks, proper record-keeping of

all checks is strongly recommended.
