1.2 Safety
Please read safety precautions before installation
Incorrect installation due to ignoring instructions can cause serious damage or
injury.
WARNING: ELECTRICAL HAZARD
Do not modify the length of the power supply cord or use an
extension cord to power the unit.
Do not share the electrical outlet with other appliances.
Improper or insufficient power supply can cause fire or
electrical shock.
WARNING: INSTALLATION REQUIREMENTS
Installation must be performed by a licensed contractor,
and per the instructions in the installation manual. Improper
installation can cause water leakage, electrical shock, or fire.
In North America, installation must be performed in
accordance with the requirement of NEC (National Electric
Code) and CEC (Canadian Electric Code) by licensed and
qualified personnel only.
Only contact a licensed contractor for repair or maintenance
of this unit.
Only use the included accessories, parts, and specified
parts for installation. Using non-standard parts can cause
water leakage, electrical shock, fire, and can cause the unit
to fail.
Install the unit in a solid location that can support the unit’s
weight. If the chosen location cannot support the unit’s
weight, or the installation is not done properly, the unit may
drop and cause serious injury and/or damage.
Before you install the unit, consider strong winds, typhoons
and earthquakes that might affect your unit and locate it
accordingly. Failure to do so could cause the equipment to
fail.
After installation, ensure there are no refrigerant leaks and
that the unit is operating properly. Refrigerant is both toxic
and flammable and poses a serious health and safety risk.
WARNING:
This product can expose you to chemicals including Lead
and Lead components, which are known to the State
of California to cause cancer and birth defects or other
reproductive harm. For more information go to www.

Installation Instructions
Bosch Climate 5000 Series Multi Zone Ductless Air Conditioner / Heat Pump (06.2022)
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.
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.
WARNING: 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.
NOTICE: IMPROPER OPERATION
In certain functional environments, such as kitchens, server
rooms, etc., the use of specially designed air-conditioning
units is highly recommended.

6 Outdoor unit installation
Step 1: Select installation location
The outdoor unit should be installed in the location that meets the following
requirements:
Place the outdoor unit as close to the indoor unit as possible.
Ensure that there is enough room for installation and maintenance.
The air inlet and outlet must not be obstructed or exposed to strong wind.
Ensure the location of the unit will not be subject to snowdrifts,
accumulation of leaves or other seasonal debris. If possible, provide an
awning for the unit. Ensure the awning does not obstruct airflow.
The installation area must be dry and well ventilated.
There must be enough room to install the connecting pipes and cables and
to access them for maintenance.
The area must be free of combustible gases and chemicals.
The pipe length between the outdoor and indoor unit may not exceed the
maximum allowable pipe length.
If possible, DO NOT install the unit where it is exposed to direct sunlight.
If possible, make sure the unit is located far away from your neighbors’
property so that the noise from the unit will not disturb them.
If the location is exposed to strong winds (for example: near a seaside),
the unit must be placed against the wall to shelter it from the wind. If
necessary, use an awning. (See Fig.4 & 5)
Figure 4
Strong wind
Strong wind
Figure 5
Strong wind
Install the indoor and outdoor units, cables and wires at least 3 ft from
televisions or radios to prevent static or image distortion. Depending
on the radio waves, a 3 ft distance may not be enough to eliminate all
interference.
Step 2: Install outdoor unit.
NOTICE:
Be sure to remove any obstacles that may block air
circulation.
Make sure to meet minimum spatial requirement (Figure
8 & 9) to ensure there is enough room for installation and
maintenance.
Fix the outdoor unit with anchor bolts (M10).
