2. GENERAL SAFETY PRECAUTIONS

All activities described in this manual shall be carried out by an
installer.

Be sure to wear adequate personal protection equipment (protection
gloves, safety glasses, …) when performing installation, maintenance
or service to the unit.

If not sure of installation procedures or operation of the unit, always
contact your local dealer for advice and information.

Improper installation or attachment of equipment or accessories
could result in electric shock, short-circuit, leaks, fire or other damage
to the equipment. Be sure only to use accessories and optional
equipment made by Daikin which are specially designed for use with
the products as of subject in this manual and have them installed by
an installer.

The precautions listed here are divided into the following four types.
They all cover very important topics, so be sure to follow them
carefully.

DANGER: ELECTRICAL SHOCK

Switch off all power supply before removing the switchbox
service panel or before making any connections or
touching electrical parts.

Do not touch any switch with wet fingers. Touching a switch
with wet fingers can cause electrical shock. Before
touching electrical parts, turn off all applicable power
supply.

To avoid electric shock, be sure to disconnect the power
supply 1 minute or more before servicing the electrical
parts. Even after 1 minute, always measure the voltage at
the terminals of main circuit capacitors or electrical parts
and, before touching, be sure that those voltages are
50 V DC or less.

When service panels are removed, live parts can easily be
touched by accident. Never leave the unit unattended
during installation or servicing when the service panel is
removed.

DANGER: DO NOT TOUCH PIPING AND INTERNAL
PA RT S

Do not touch the refrigerant piping, water piping or internal
parts during and immediately after operation. The piping
and internal parts may be hot or cold depending on the
working condition of the unit.

Your hand may suffer burns or frostbite if you touch the
piping or internal parts. To avoid injury, give the piping and
internal parts time to return to normal temperature or, if
you must touch them, be sure to wear protective gloves.

WARNING

■ Tear apart and throw away plastic packaging bags so
that children will not play with them.
Children playing with plastic bags face danger of death
by suffocation.

■ Safely dispose of packing materials. Packing materials,
such as nails and other metal or wooden parts, may
cause stabs or other injuries.

■ Ask your dealer or qualified personnel to carry out
installation work.
Do not install the machine by yourself.
Improper installation may result in water leakage, electric
shocks or fire.

■ Perform installation work in accordance with this
installation manual.
Improper installation may lead to water leakage, electric
shocks or fire.

■ Be sure to use only the specified accessories and parts
for installation work.
Failure to use the specified parts may result in water
leakage, electric shocks, fire, or the unit falling.

■ Install the unit on a foundation that can withstand its
weight.

■ Insufficient strength may result in the fall of equipment
and causing injury.

■ Carry out the specified installation work in consideration
of strong winds, hurricanes, or earthquakes.
Improper installation work may result in accidents due to
fall of equipment.

■ Make certain that all electrical work is carried out by
qualified personnel according to the local laws and
regulations and this installation manual, using a separate
circuit.
Insufficient capacity of the power supply circuit or
improper electrical construction may lead to electric
shocks or fire.

■ Be sure to install an earth leakage circuit breaker in
accordance with relevant local and national regulations.
Failure to do so may cause electrical shock and fire.

■ Make sure that all wiring is secure, using the specified
wires and ensuring that external forces do not act on the
terminal connections or wires.
Incomplete connection or fixing may cause a fire.

■ When wiring between the indoor and the outdoor units
and wiring the power supply, form the wires so that the
panels can be securely fastened.
If the panels are not in place, overheat of the terminals,
electric shocks or a fire may be caused.

■ After completing the installation work, check to make
sure that there is no leakage of refrigerant gas.

■ Never directly touch any accidental leaking refrigerant.
This could result in severe wounds caused by frostbite.

■ Electrical work must be carried out in accordance with
the installation manual and the national electrical wiring
rules or code of practice.
Insufficient capacity or incomplete electrical work may
cause electrical shock or fire.

■ Be sure to use a dedicated power circuit. Never use a
power circuit shared by another appliance.

■ For wiring, use a cable long enough to cover the entire
distance with no connection. Do not use an extension
cord. Do not put other loads on the power supply, use a
dedicated power circuit.
Failure to do so may cause abnormal heat, electric
shock, or fire.

■ Do not touch the refrigerant pipes during and
immediately after operation as the refrigerant pipes may
be hot or cold, depending on the condition of the
refrigerant flowing through the refrigerant piping,
compressor and other refrigerant cycle parts. Your hands
may suffer burns or frostbite if you touch the refrigerant
pipes. To avoid injury, give the pipes time to return to
normal temperature or, if you must touch them, be sure
to wear proper gloves.

CAUTION

■ For use of units in applications with temperature
alarm settings it is advised to foresee a delay of 10
minutes for signalling the alarm in case the alarm
temperature is exceeded. The unit may stop for
several minutes during normal operation for
"defrosting of the unit" or when in "thermostat-stop"
operation.

■ Earth the unit.
Earth resistance should be according to local laws and
regulations.
Do not connect the earth wire to gas or water pipes,
lightning conductor or telephone earth wire.
Incomplete earthing may cause electric shocks.

- Gas pipe.

Ignition or explosion may occur if the gas leaks.

-Water pipe.

Hard vinyl tubes are not effective earths.

- Lightning conductor or telephone earth wire.

Electric potential may rise abnormally if struck by a
lightning bolt.

■ Install the indoor and outdoor units, power wire and
connecting wire at least 1 meter away from televisions or
radios to prevent image interference or noise.
(Depending on the radio waves, a distance of 1 meter
may not be sufficient to eliminate the noise.)

■ Do not rinse the unit. This may cause electric shocks or
fire.

■ Do not install the unit in places such as the following:

- Where there is mist of mineral oil, oil spray or vapour.

Plastic parts may deteriorate, and cause them to fall
out or water to leak.

- Where corrosive gas, such as sulphurous acid gas, is

produced.
Corrosion of copper pipes or soldered parts may
cause the refrigerant to leak.

- Where there is machinery which emits

electromagnetic waves.
Electromagnetic waves may disturb the control
system, and cause malfunction of the equipment.

- Where flammable gases may leak, where carbon

fibre or ignitable dust is suspended in the air or
where volatile flammables, such as thinner or
gasoline, are handled. Such gases may cause a fire.

- Where the air contains high levels of salt such as that

near the ocean.

- Where voltage fluctuates a lot, such as that in

factories.

- In vehicles or vessels.

- Where acidic or alkaline vapour is present.

3. INTRODUCTION

3.1. General information

This installation manual concerns Monoblock units of the GBS
Altherma series.

The Monoblock units exist out of an outdoor installed unit (EBHQ)
and an indoor installed (wall mounted) unit (EKCB).

These units are used for both heating and cooling applications. The
units can be combined with Daikin fan coil units, floor heating
applications, low temperature radiators, domestic hot water tank
(option) and solar kit (option).

A user interface is standard supplied with the unit to control your
installation.

Heating/cooling units and heating only units

The monoblock unit range consists of two main versions: a
heating/cooling version (uses EKCBX indoor unit) and a heating only
version (uses EKCBH indoor unit), both available in 2 capacity sizes:
6 kW (EBHQ006) or 8 kW (EBHQ008).

3.2. Combination and options

Possible combinations

s Indoor units

Outdoor units

EBHQ006BAV3 Possible Possible
EBHQ008BAV3 Possible Possible

Both versions (heating only and heating/cooling) are standard
delivered with a backup heater kit (EKMBUH) for additional heating
capacity during cold outdoor temperatures. The backup heater also
serves as a backup in case of malfunctioning of the unit and for
freeze protection of the outside water piping during winter time. The
backup heater factory set capacity is 6 kW, however, depending on
the installation, the installer can limit the backup heater capacity to
3 kW. The backup heater capacity decision is a mode based on the
equilibrium temperature, see scheme below.

that meets with your customer's approval.

■ The unit is designed to be installed in an outdoor location.

■ The space around the unit is adequate for maintenance and

servicing (refer to "7.3. Service space" on page 10).

■ The space around the unit allows for sufficient air circulation.
There must be sufficient space for air passage and no
obstructions around the air intake and the air exhaust (see
"Installing near a wall or obstacle" on page 9).

■ There must be sufficient space for carrying the unit into and out
of the site.

■ There is no danger of fire due to leakage of inflammable gas.
The site must be free from the possibility of flammable gas
leakage in a nearby place.

■ The equipment is not intended for use in a potentially explosive
atmosphere.

■ Choose a place solid enough to bear the weight and vibration of

■ Since drain flows out of the unit, do not place anything under the
unit which must be kept away from moisture.

■ Ta ke care that in the event of a water leak, water cannot cause
any damage to the installation space and surroundings (e.g. in
case of a blocked drain pipe).

■ Install the unit and power cords at least 3 m away from television
and radio sets. This is to prevent interference to images and
sounds.
Depending on radio wave conditions, electromagnetic
interference may still occur even if installed more than 3 m away.

EBHQ006+008BAV3 + EKCBX/H008BAV3

Unit for air to water heat pump system

4PW64602-1 – 08.2010

■ Select the location of the unit in such a way that the sound
generated by the unit does not disturb anyone, and the location
is selected according the applicable legislation.
Although the noise produced by the unit during operation is low,
avoid installation near to places where even low noise levels can
be disturbing (e.g., bedroom windows, terraces, next-door
neighbours).

■ Do not install the unit in places often used as workplace.
In case of construction works (e.g. grinding works) where a lot of
dust is created, the unit must be covered.

■ Be sure that sufficient precautions are taken, in accordance with
relevant local laws and regulations, in case of refrigerant
leakage.

Wheater dependent precautions

■ Select a place where the rain can be avoided as much as
possible.

■ In heavy snowfall areas, it is very important to select an
installation site where the snow will not affect the unit. If lateral
snowfall is possible, Be sure that the heat exchanger coil is not
affected by the snow (if necessary construct a lateral canopy).

■ Ensure that water cannot cause any damage to the location by
adding water drains to the foundation and prevent water traps in
the construction.

■ Do not install the unit in areas where the air contains high levels
of salt such as that near the ocean, corrosion may shorten the
life of the unit.

■ Prevent direct exposure to winds coming from the sea.

■ Be sure that the air inlet and outlet of the unit are not positioned

towards the main wind direction. frontal wind will disturb the
operation of the unit. If necessary, use a screen to block the wind.

■ When installing the unit in a place exposed to strong wind, pay
special attention to the following.
Strong winds of 5 m/sec or more blowing against the unit's air
outlet cause short circuit (suction of discharge air), and this may
have the following consequences:

- deterioration of the operational capacity,

- frequent frost acceleration in heating operation,

- disruption of operation due to rise of high pressure,

- when a strong wind blows continuously on the face of the

unit, the fan can start rotating very fast until it breaks.
Refer to the figures for installation of this unit in a place where
the wind direction can be foreseen.

-Turn the air outlet side toward the building's wall, fence or

screen.

Selecting an outdoor location in cold climates

NOTICE

When operating the unit in a low outdoor ambient
temperature, be sure to follow the instructions described
below.

■ To prevent exposure to wind, install the unit with its suction side
facing the wall.

■ Never install the unit at a site where the suction side may be
exposed directly to wind.

■ To prevent exposure to wind, install a baffle plate on the air
discharge side of the outdoor unit.

■ When installing the unit in a place frequently exposed to snow,
pay special attention to the following:

- Elevate the foundation as high as possible.

- Select an installation site where the snow will not affect the

unit. If lateral snowfall is possible, make sure that the heat
exchanger coil is not affected by the snow (if necessary
construct a lateral canopy).

Construct a large canopy.

Construct a pedestal.
Install the unit high enough off the ground
to prevent burying in snow.

Place of installation

■ Prepare a water drainage channel around the outdoor unit, to
drain waste water from around the unit.

■ If the water drainage of the unit is not easy, please build up the
unit on a foundation of concrete blocks, etc. (the height of the
foundation should be maximum 150 mm).

■ If you install the unit on a frame, please install a waterproof plate
within 150 mm of the underside of the unit in order to prevent the
invasion of water from the lower direction.

■ If you install the unit on a building frame,
please install a waterproof plate (field
supply)(within 150 mm of the underside of
the unit) in order to avoid the drainwater
dripping. (See figure).

Make sure there is enough room to do the installation

CAUTION

When circulation in each space heating loop (FHL1..3) is
controlled by remotely controlled valves (M1..3), it is
important to provide a by-pass valve (7) to avoid the flow
switch safety device from being activated.

The by-pass valve should be selected as such that at all
time the minimum water flow as mentioned under
"10. Piping connection work" on page 18 is guaranteed.

It is recommended to select a pressure difference
controlled by-pass valve.

Domestic water heating

When domestic water heating mode is enabled (either manually by
the user, or automatically through a schedule timer) the target
domestic hot water temperature will be achieved by a combination of
the heat exchanger coil and the electrical booster heater.

When the domestic hot water temperature is below the user
configured set point, the 3-way valve will be activated to heat the
domestic water by means of the heat pump. In case of large domestic
hot water demand or a high domestic hot water temperature setting,
the booster heater (9) can provide auxiliary heating.

CAUTION

It is possible to connect either a 2-wire or a 3-wire 3-way
valve (7). Make sure to fit the 3-way valve correctly. For
more details, refer to "Wiring the 3-way valve" on page 28.

The unit can be configured so that at low outdoor
temperatures the domestic water is exclusively heated by
the booster heater. This assures that the full capacity of the
heat pump is available for space heating.

Details on domestic hot water tank configuration for low
outdoor temperatures can be found under "13.9. Field
settings" on page 31, field settings [5-02] to [5-04].

Pump operation and space heating and cooling

According to the season, the customer will select cooling or heating
on the room thermostat (T). This selection is not possible by
operating the user interface.

When space heating/cooling is requested by the room thermostat
(T), the pump will start operating and the unit (1) will switch to
"heating mode"/"cooling mode". The unit (1) will start operating to
achieve the target leaving cold/hot water temperature.

In case of cooling mode, the motorised 2-way valve (12) will close as
to prevent cold water running through the floor heating loops (FHL).

CAUTION

Make sure to connect the thermostat wires to the correct
terminals (see "Connection of the thermostat cable" on
page 27) and to configure the DIP switch toggle switches
correctly (see "13.2. Room thermostat installation
configuration" on page 28).

CAUTION

Wiring of the 2-way valve (12) is different for a NC (normal
closed) valve and a NO (normal open) valve! Make sure to
connect to the correct terminal numbers as detailed on the
wiring diagram.

Details on pump configuration can be found under
"13.3. Pump operation configuration" on page 29.

Space heating and cooling

According to the season, the customer will select cooling or heating
through the user interface.

The unit (1) will operate in cooling mode or heating mode to achieve
the target leaving water temperature.

With the unit in heating mode, the 2-way valve (12) is open. Hot water
is provided to both the fan coil units and the floor heating loops.

With the unit in cooling mode, the motorised 2-way valve (12) is
closed to prevent cold water running through the floor heating loops
(FHL).

CAUTION

When closing several loops in the system by remotely
controlled valves, it might be required to install a by-pass
valve (8) to avoid the flow switch safety device from being
activated. See also "8.2. Application 2" on page 11.

CAUTION

Wiring of the 2-way valve (12) is different for a NC (normal
closed) valve and a NO (normal open) valve! Make sure to
connect to the correct terminal numbers as detailed on the
wiring diagram.

CAUTION

■ Be sure that the boiler and the integration of the boiler
in the system is in accordance with relevant local laws
and regulations.

■ Always install a 3-way valve, even if no domestic hot
water tank is installed. This to ensure that the freeze
protection function (see "[4-04] Freeze protection
function" on page 33) can operate when the boiler is
active.

8.5. Application 5

Space heating with an auxiliary boiler (alternating operation)

Space heating application by either the Daikin unit or by an auxiliary
boiler connected in the system. The decision whether either the
EBHQ* unit or the boiler will operate can be achieved by an auxiliary
contact or an EKCB* indoor controlled contact.

The auxiliary contact can e.g. be an outdoor temperature thermostat,
an electricity tariff contact, a manually operated contact, etc. See
"Field wiring configuration A" on page 14.

The EKCB* unit controlled contact (also called 'permission signal for
the auxiliary boiler") is determined by the outdoor temperature
(thermistor located at the outdoor unit). See "Field wiring
configuration B" on page 14.

Bivalent operation is only possible for space heating operation, not
for the domestic water heating operation. Domestic hot water in such
an application is always provided by the domestic hot water tank
which is connected to the Daikin unit.

The auxiliary boiler must be integrated in the piping work and in the
field wiring according to the illustrations below.

Operation

■ Configuration A

When the room thermostat requests heating, either the EBHQ*
unit or the boiler starts operating, depending on the position of
the auxiliary contact (A).

■ Configuration B
When the room thermostat requests heating, either the EBHQ*

unit or the boiler starts operating, depending on the outdoor
temperature (status of "permission signal for the auxiliary
boiler").

When the permission is given towards the boiler, the space
heating operation by the EBHQ* unit will be automatically
switched off.

For more details see field setting [C-02~C-04].

NOTICE

■ Configuration A

Make sure that auxiliary contact (A) has sufficient
differential or time delay so as to avoid frequent

Y

changeover between the EBHQ* unit and the boiler. If
the auxiliary contact (A) is an outdoor temperature
thermostat, make sure to install the thermostat in the
shade, so that it is not influenced or turned ON/OFF
by the sun.

Configuration B

Make sure that the bivalent hysteresis [C-04] has
sufficient differential to avoid frequent changeover
between the EBHQ* unit and the boiler. As the outdoor
temperature is measured via the outdoor unit’s air
thermistor, make sure to install the outdoor unit in the
shade, so that it is not influenced by the sun.

Frequent switching may cause corrosion of the boiler
in an early stage. Contact the manufacturer of the
boiler.

■ During heating operation of the EBHQ* unit, the unit
will operate so as to achieve the target leaving water
temperature as set on the user interface. When
weather dependent operation is active, the water
temperature is determined automatically depending
on the outdoor temperature.

During heating operation of the boiler, the boiler will
operate so as to achieve the target leaving water
temperature as set on the boiler controller.

Never set the target leaving water temperature set
point on the boiler controller above 55°C.

■ Make sure to only have 1 expansion vessel in the
water circuit. An expansion vessel is already
premounted in the unit.

NOTICE

Make sure to configure the DIP switch SS2-3 on the PCB
of the EKCB(H/X)* switch box correctly. Refer to
"13.2. Room thermostat installation configuration" on
page 28.

For configuration B: Make sure to configure the field
settings [C-02, C-03 and C-04] correctly. Refer to "Bivalent
operation" on page 37.

CAUTION

Make sure that return water to the EBHQ* heat exchanger
never exceeds 55°C.

For this reason, never put the target leaving water
temperature set point on the boiler controller above 55°C
and install an aquastat

(a)

valve in the return water flow of

the EBHQ* unit.
Make sure that the non-return valves (field supply) are

correctly installed in the system.
Make sure that the room thermostat (th) is not frequently

turned ON/OFF.
Daikin shall not be held liable for any damage resulting

from failure to observe this rule.

(a) The aquastat valve must be set for 55°C and must operate to close the return

water flow to the unit when the measured temperature exceeds 55°C. When the
temperature drops to a lower level, the aquastat valve must operate to open the
return water flow to the EBHQ* unit again.

Installation manual

14

CAUTION

Manual permission towards the EBHQ* unit on the boiler.
In case only the EBHQ* unit should operate in space

heating mode, disable the bivalent operation via setting
[C-02].

In case only the boiler should operate in space heating
mode, increase the bivalent ON temperature [C-03] to
25°C.
