7.3 RESTARTING THE HYBRID SYSTEM AFTER AN
INTERRUPTION IN OPERATION
▶ Ensure that the shut-off valves on the liquid and gaseous refrigerant
pipe work are open.
▶ If not already, interrupt the power supply to the hybrid manager and
the external unit.
▶ Undo the outer case screws at the top and bottom of the hybrid
manager (Fig. 23, page 25) and lift off the case.
▶ Undo fixing screw on the left hand. side of the hybrid control module
( Fig. 40, page 33).
▶ Push out the spring plate and tilt the hybrid control module forward.
▶ Undo two screws and remove the small cover at the back ( Fig. 41,
page 33).
▶ Disconnect the BUS cable at terminals S2/S3 ( Fig. 43, page 33).
8 ENVIRONMENTAL PROTECTION/DISPOSAL
Environmental protection is one of the fundamental company policies of
the Bosch Group.
Quality of products, efficiency and environmental protection are equally
important objectives for us. Laws and requirements aimed at protecting
the environment are strictly adhered to.
To protect the environment we will, subject to economical aspects, use
the best possible technology and materials.
PACKAGING
We participate in the recycling programmes of the countries in which our
products are sold to ensure optimum recycling.
All of our packaging materials are environmentally compatible and can
be recycled.
8.1 DISPOSING OF REFRIGERANT
The appliance is charged with R410A refrigerant.
R410A is a greenhouse gas. It must not enter the environment.
▶ If you wish to discard refrigerant, please contact your local authorities
and ask for the correct method of disposal.
8.2 APPLIANCE DISPOSAL
Old appliances contain valuable materials that must be recycled.
The appliance is marked with the symbol.
▶ Sort and dispose of packaging materials according to the your local
recycling system.
▶ Have this appliance and any accessories disposed of in accordance
with locally applicable regulations by a licensed contractor.
▶ Never dispose of the appliance in the normal refuse (dust bin).
▶ If the appliances have batteries or rechargeable batteries, dispose of
these separately beforehand according to local regulations.
▶ Dispose of electric and electronic equipment separately according to
local requirements.
9 INSPECTION AND MAINTENANCE
HANDLING REFRIGERANT
▶ Only qualified and authorised refrigeration engineers may work on the
refrigerant system.
▶ During installation work, use the tools and components specifically
designed for handling R410A refrigerant.
▶ Check for leaks in the refrigerant system. Escaping refrigerant coming
into contact with a naked flame will produce poisonous gases.
▶ Never release refrigerant to the atmosphere.
If refrigerant leaks and touches the skin, it can cause frostbite.
▶ In case of a refrigerant leak, never touch any part of the air to water
heat pump.
▶ Avoid skin or eye contact with refrigerant.
▶ Seek medical attention if you get refrigerant on your skin or in your
eyes.
9.1 PREPARING FOR INSPECTION AND MAINTENANCE
To ensure low energy consumption and environmental impact over the
long term, we recommend arranging a maintenance service at a regular
interval of 12 months.
NOTICE: Damage to the external unit from low
compressor operating temperature!
The Power supply to the external unit must be “Live” for
at least 12 hours before any heating demand. This is to
ensure that the compressor is warmed up sufficiently to
avoid any liquid refrigerant from entering the
compressor. This is particularly important during colder
periods.The 12 hour period also compensates for any
unsettling of the lubricating oil within the compressor
which may have occurred during transportation.If this
12 hour time period cannot be met damage to the
outdoor unit may result.
▶ Never interrupt the power supply during normal
operation.
CAUTION: Incorrect disposal is an environmental
hazard!
Escaping refrigerant damages the environment.
▶ Refrigerant may be disposed of by qualified installers
only.
Appliances with this symbol may not be disposed of with
domestic waste at the end of their service life.
Compared to previously used refrigerants, the R410A
refrigerant operates at a pressure that is approx. 1.6-
times higher.
DANGER: Danger to life through electric shock!
▶ Before carrying out work on electrical components,
isolate them from the power supply (230 V AC) (fuse,
circuit breaker) and secure against unintentional
reconnection.
WARNING: Risk of injury and material losses through
incorrect inspection and maintenance.
▶ The hybrid system, the heat source and the
components may only be sited and installed by the
manufacturer or an authorised contractor.
▶ Any service work on the refrigerant circuit must be
carried out by an F-Gas qualified refrigeration
engineer whose employer is F-Gas certified.
