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.

DANGER: ELECTRICAL SHOCK

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

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.

Outdoor unit for air to water heat pump

4PW68002-1A – 03.2011

Warning

■ 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.

■ Consult your local dealer regarding what to do in case of
refrigerant leakage. When the unit is to be installed in a small
room, it is necessary to take proper measures so that the
amount of any leaked refrigerant does not exceed the
concentration limit in the event of a leakage. Otherwise, this may
lead to an accident due to oxygen depletion.

■ 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, typhoons, 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 applicable legislation 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.

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

■ If refrigerant gas leaks during installation work, ventilate the area
immediately.
Toxic gas may be produced if refrigerant gas comes into contact
with fire.

■ After completing the installation work, check to make sure that
there is no leakage of refrigerant gas.
Toxic gas may be produced if refrigerant gas leaks into the room
and comes into contact with a source of fire, such as a fan
heater, stove or cooker.

■ When planning to relocate former installed units, you must first
recover the refrigerant after the pump down operation. Refer to
chapter "13. Pump down operation" on page 13.

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

■ Be sure to install an earth leakage circuit breaker in accordance
with applicable legislation. Failure to do so may cause electrical
shock and fire.

■ 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.

■ During pump down operation, stop the compressor before
removing the refrigerant piping.
If the compressor is still running and the stop valve is open
during pump-down, air will be sucked in when the refrigerant
piping is removed, causing abnormal pressure in the freezer
cycle which will lead to breakage and even to injury.

■ During installation, attach the refrigerant piping securely before
running the compressor.
If the compressor is not attached and the stop valve is open
during pump-down, air will be sucked in when the compressor is
running, causing abnormal pressure in the freezer cycle which
will lead to breakage and even to injury.

Caution

■ Earth the unit.
Earthing resistance should be according to applicable
legislation.
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 outdoor 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 for

example a kitchen.
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 fiber 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.

alarm in case the alarm temperature is exceeded. The unit may
stop for several minutes during normal operation for "defrosting
the unit", or when in "thermostat stop" operation.

■ Tighten the flare nut according to the specified method such as
with a torque wrench.
If the flare nut is tightened too hard, the flare nut may crack after
a long time and cause refrigerant leakage.

3. BEFORE INSTALLATION

WARNING

Since maximum working pressure for this outdoor unit is

4.17 MPa or 41.7 bar, pipes of larger wall thickness may be
required. Refer to paragraph "8.1. Selection of piping

material" on page 9.

3.4. Model identification

ERLQ units include special equipment (insulation, bottom plate
heater,...) to ensure good operation in areas where low ambient
temperature can occur together with high humidity conditions. In such
conditions the ERHQ models may experience problems with severe
ice build up on the aircooled coil. In case such conditions are
expected, the ERLQ must be installed instead. These models contain
countermeasures (insulation, bottom plate heater,...) to prevent
freeze up.

3.1. Scope of the manual

This manual describes the procedures for handling, installing and
connecting ERHQ and ERLQ units. This manual has been prepared
to ensure adequate maintenance of the unit, and it will provide help if
problems occur.

3.2. Precautions for R410A

■ The refrigerant requires strict cautions for keeping the system
clean, dry and tight.

- Clean and dry
Foreign materials (including mineral oils or moisture) should be
prevented from getting mixed into the system.

- Tight
Read "9. Precautions on refrigerant piping" on page 9 carefully
and follow these procedures correctly.

■ Since R410A is a mixed refrigerant, the required additional
refrigerant must be charged in its liquid state. (If the refrigerant is
in state of gas, its composition changes and the system will not
work properly).

■ The connected indoor unit must be the EKHBH/X008 unit
designed exclusively for R410A.

3.3. Installation

■ For installation of the indoor unit, refer to the indoor unit
installation manual.

■ Never operate the unit without the thermistors, burning of the
compressor may result.

■ Be sure to confirm the model name and the serial no. of the
outer (front) plates when attaching/detaching the plates to avoid
mistakes.

■ When closing the service panels, take care that the tightening
torque does not exceed 4.1 N•m.

INFORMATION

■ An ERLQ0*BA/BB outdoor unit can only be
connected to an EKHBH/X008BA/BB indoor unit
(bottom plate heater at outdoor unit has to be
controlled by indoor unit).

■ An ERHQ0*BA/BB outdoor unit can be connected to
an EKHBH/X008BA/BB indoor unit or to an EKHBH/

5.1. General

WARNING

■ Make sure to provide for adequate measures in order
to prevent that the outdoor unit be used as a shelter
by small animals.

■ Small animals making contact with electrical parts can
cause malfunctions, smoke or fire. Please instruct the
customer to keep the area around the unit clean.

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

■ Choose a place solid enough to bear the weight and vibration of
the unit, where the operation noise will not be amplified.

■ Choose a location where the hot air discharged from the unit or
the operation noise will not cause a nuisance to the neighbours
of the user.

■ Avoid places near a bedroom and the like, so that the operation
noise will cause no trouble.

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

■ There must be sufficient space for air passage and no
obstructions around the air inlet and the air outlet.

■ The site must be free from the possibility of flammable gas
leakage in a nearby place.

■ Locate the unit so that the noise and the discharged hot air will
not annoy the neighbours.

■ Install units, power cords and inter-unit cables 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.

■ In coastal areas or other places with salty atmosphere of sulfate
gas, corrosion may shorten the life of the outdoor unit.

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

■ Select an installation site where the following conditions are
satisfied and that meets with your customer's approval.

11. LEAK TEST AND VACUUM DRYING

When all piping work is complete and the outdoor unit is connected to
the indoor unit, it is necessary to:

■ check for any leakages in the refrigerant piping

■ to perform vacuum drying to remove all moisture in the

refrigerant piping.

If there is a possibility of moisture being present in the refrigerant
piping (for example, rainwater may have entered the piping), first
carry out the vacuum drying procedure below until all moisture has
been removed.

■ All refrigerant pipe joints should be tightened with a torque

wrench at the specified tightening torque. See "10.2. Connecting

the refrigerant piping to the outdoor unit" on page 10 for details.

11.1. General guidelines

■ All piping inside the unit has been factory tested for leaks.

■ Use a 2-stage vacuum pump with a non-return valve which can

evacuate to a gauge pressure of –100.7 kPa (5 Torr absolute,
–755 mm Hg).

■ Connect the vacuum pump to the service port of the gas stop
valve.

NOTICE

■ Make sure that the gas stop valve and liquid stop
valve are firmly closed before performing the leak test
or vacuum drying.

■ Use a vacuum pump for R410A exclusively. Using the
same vacuum pump for different refrigerants may
damage the vacuum pump or the unit.

WARNING

■ Do not mix any substance other than the specified
refrigerant (R410A) into the refrigeration cycle.

■ When refrigerant gas leaks occur, ventilate the room
as soon and as much as possible.

■ R410A, as well as other refrigerants, should always
be recovered and never be released directly into the
environment.

INFORMATION

Do not purge the air with refrigerants. Use a vacuum pump
to evacuate the installation.

■ If using additional refrigerant, perform air purging from the
refrigerant pipes and indoor unit using a vacuum pump, then
charge additional refrigerant.

INFORMATION

National implementation of EU regulation on certain
fluorinated greenhouse gases may require to provide the
appropriate official national language on the unit.
Therefore, an additional multilingual fluorinated
greenhouse gases label is supplied with the unit.

Sticking instructions are illustrated on the backside of that
label.

DANGER

■ When the power is on, please close the front panel
when leaving the unit unattended.

■ Charging with an unsuitable substance may cause
explosions and accidents, so always ensure that the
appropriate refrigerant (R410A) is charged.

■ Be sure to charge the specified amount of refrigerant in liquid
state to the liquid pipe.
Since this refrigerant is a mixed refrigerant, adding it in gas form
may cause the refrigerant composition to change, preventing
normal operation.

■ Before charging, check whether the refrigerant cylinder is
equipped with a siphon tube or not (the cylinder should be
marked with "liquid filling siphon attached" or something similar).

Charge the liquid
refrigerant with the
cylinder in upright
position.

Charge the liquid
refrigerant with the
cylinder in up-side-down
position.

■ Be sure to use tools exclusively for R410A to ensure required
pressure resistance and to prevent foreign materials from mixing
into the system.

12.3. Calculating the additional refrigerant

It is not necessary to charge additionally if the piping length is under
10 m.

If the piping length is over 10 m please determine the additional
amount of refrigerant to be charged using the formula below.

R=(total length (m) of liquid piping – 10 m) x 0.02

R=additional charge (kg)(rounded in units of 0.01 kg)

Determine the weight of refrigerant to be charged additionally and fill
in the amount in the service sticker on the rear side of the stop valve

12.4. Complete recharging

NOTICE

Before recharging, make sure to execute vacuum drying of
the internal piping of the unit as well.

In case complete recharging is required, refer to the nameplate of the
unit. The nameplate states the type of refrigerant and necessary
amount.

Total charging amount <unit: kg>

Charge of refrigerant (kg) depends on total liquid piping length.

Total refrigerant charge=1.7 kg + (total length (m) of liquid
piping–10 m) x 0.02

Remark: Factory refrigerant charge is 1.7 kg.

13. PUMP DOWN OPERATION

In order to protect the environment, be sure to pump down when
relocating or disposing of the unit. The pump down operation will
extract all refrigerant from the piping into the outdoor unit.

13.1. Pump down procedure

1 Remove the valve lid from liquid stop valve and gas stop valve.

2 Carry out the forced cooling operation.

3 After 5 to 10 minutes (after only 1 or 2 minutes in case of very

low ambient temperatures (<–10°C)), close the liquid stop valve
with a hexagonal wrench.

NOTICE

Take care that while running forced cooling operation the
water temperature remains higher than 5°C (see
temperature read out of the indoor unit). You can achieve
this, for example, by activating all fans of the fan coil units.

14. ELECTRICAL WIRING WORK

WARNING

■ All wiring must be performed by an authorized
electrician.

■ Electrical connections shall be made to fixed wiring.

■ All components procured on the site and all electric

construction shall comply with the applicable
legislation.

DANGER: HIGH VOLTAGE

To avoid electrical shock, make 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, make sure that those
voltages are 50 V DC or less.

NOTICE
To persons in charge of electrical wiring work:

Do not operate the unit until the refrigerant piping is
complete. (Running it before the piping is ready will break
the compressor.)
