PLACE FOR FUTURE REFERENCE.
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 MADE BY DAIKIN WHICH ARE
SPECIFICALLY DESIGNED FOR USE WITH THE

1. INTRODUCTION
1.1. General information
Thank you for purchasing this unit.
The outdoor unit is the air to water Daikin ERSQ or ERRQ heat
pump.
ERRQ units include special equipment (insulation, heater sheet, ...)
to ensure good operation in areas where low ambient temperature
can occur together with high humidity conditions. In such conditions
the ERSQ models may experience problems with severe ice build up
on the aircooled coil. In case such conditions are expected, the
ERRQ must be installed instead. These models contain countermeasures (insulation, heater sheet, ...) to prevent freeze up.
NOTE
Possible options
For ERSQ models an optional bottom plate heater kit EKBPHT16A
can be connected to the outdoor unit. Refer to the installation manual
of the bottom plate heater kit for further details.
ERRQ EK016SNC
An ERSQ or ERRQ outdoor unit can only be connected
with the EKHBRD indoor unit.
Heater sheet Drain socket

The precautions listed here are divided into the following two types.
Both cover very important topics, so be sure to follow them carefully.
WARNING
If the warning is not observed, it may cause serious casualties.
CAUTION
If the caution is not observed, it may cause injury or damage to the
equipment.
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.
■ 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 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.
■ 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, the terminals may overheat
and 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.
■ Before touching electric terminal parts, turn off power switch.

Caution
4. INSTALLATION OF THE UNIT
■ 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 indoor unit" or when in "thermostat-stop" operation.
■ Live parts can be easily touched by accident.
Never leave the unit unattended during installation or servicing
when the service panel is removed.
■ Earth the unit.
Earth resistance should be according to national regulations
Do not connect the earth wire to gas or water pipes,
lightning conductor or telephone earth wire.
Incomplete grounding 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.
■ Be sure to install an earth leakage circuit breaker.
Failure to install an earth leakage circuit breaker may cause
electric shocks and fire.
■ Install drain piping according to this installation manual to
ensure good drainage, and insulate the pipe to prevent
condensation. See combination table in "General information"
on page 1.
Improper drain piping may cause water leakage, and make the
furnitures get wet.
■ 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.
■ Where voltage fluctuates a lot, such as that in factories.
■ In vehicles or vessels.
■ Where acidic or alkaline vapour is present.
■ Do not allow a child to mount on the outdoor unit or avoid placing
any object on the unit.
Falling or tumbling may result in injury.
■ Do not touch any refrigerant which has leaked out of refrigerant
piping connections.
This may result in frostbite.
4.1. Selecting installation location
■ 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.
1 Select an installation site where the following conditions are
satisfied and that meets with your customer's approval.
- Places which are well-ventilated.
- Places where the unit does not bother next-door neighbours.
- Safe places which can withstand the unit's weight and
vibration and where the unit can be installed level.
- Places where there is no possibility of flammable gas or
product leak.
- The equipment is not intended for use in a potentially
explosive atmosphere.
- Places where servicing space can be well ensured.
- Places where the indoor and outdoor units' piping and wiring
lengths come within the allowable ranges.
- Places where water leaking from the unit cannot cause
damage to the location (e.g. in case of a blocked drain pipe).
- Places where the rain can be avoided as much as possible.
2 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 outdoor
unit's air outlet causes short circuit (suction of discharge air),
and this may have the following consequences:
- Deterioration of the operational capacity.
- Frequent frost acceleration.
- 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.
■ Install a baffle plate on the air suction side of the outdoor unit
and set the outlet side at a right angle to the direction of the
wind:

Selecting a location in cold climates
Refer to "General information" on page 1.
CAUTION
When operating the outdoor unit in a low outdoor ambient
temperature, be sure to follow the instructions described
below.
■ To prevent exposure to wind, install the outdoor unit with its
suction side facing the wall.
■ Never install the outdoor 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.
■ 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, make sure that the heat exchanger coil is
not affected by the snow (if necessary construct a lateral
canopy).
3 Prepare a water drainage channel around the foundation, to
drain waste water from around the unit (field supply).
4 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).
5 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.
6 When installing the unit in a place frequently exposed to snow,
pay special attention to elevate the foundation as high as
possible.
7 The outdoor unit may short circuit depending on its environment,
so use the louvers (field supply).
8 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) or use a drain kit (refer to
combination table in "General information"
on page 1) in order to avoid the drainwater
dripping. (See figure).
The equipment described in this manual may cause
electronic noise generated from radio-frequency energy.
The equipment complies to specifications that are
designed to provide reasonable protection against such
interference. However, there is no guarantee that
interference will not occur in a particular installation.
It is therefore recommended to install the equipment and
electric wires keeping proper distances away from stereo
equipment, personal computers, etc... (See figure 2)
