INTRODUCTION

General information

Thank you for purchasing this Daikin inverter chiller.

This unit is designed for outdoor installation and used for both heating and cooling applications. The unit is designed to be combined with fan coil units or air handling units for air conditioning purposes.

Heat pump and cooling only versions

This chiller range consists of 2 main versions: a heat pump (EWYQ) version and a cooling only (EWAQ) version, available in 6 standard sizes:

■V3: 9, 10, and 11 kW (single phase)

■W1: 9, 11, and 13 kW (3 phase)

Options

■Remote alarm kit EKRP1HB

■Heater tape option OP10

Both versions are also available with a heater tape option (OP10) for protecting internal water pipework at cold outdoor temperatures.

Connection to a benefit kWh rate power supply

This equipment allows for connection to benefit kWh rate power supply delivery systems. Full control of the unit will remain possible only in case the benefit kWh rate power supply is of the type that power supply is not interrupted. Refer to "Connection to a benefit kWh rate power supply" on page 14 for more details.

Scope of this manual

This manual describes the procedures for unpacking, installing and connecting all EWA/YQ models, as well as instructions for maintenance and troubleshooting of the unit.

SAFETY CONSIDERATIONS

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

■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.

■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 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.

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

■Before touching electric terminal parts, turn off power switch.

■Live parts can be easily touched by accident.

Never leave the unit unattended during installation or servicing when the service panel is removed.

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

Caution

■Earth the unit.

Earthing 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 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.

■Be sure to install an earth leakage circuit breaker.

Failure to install an earth leakage circuit breaker may cause electric shocks and fire.

■Install the power 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 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.

BEFORE INSTALLATION

Installation

■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.

■In case ambient temperatures below 0°C are expected, countermeasures need to be taken to prevent the water in the unit from freezing. In such cases, we recommend to install the heater tape option OP10 or we advise to put glycol in the system. See "Protecting the water circuit against freezing" on page 10. It is also allowed to drain the water from the system when longer periods of standstill are expected.

Model

EWAQ and EWYQ units include optional special equipment (insulation, heater tape,...) to ensure good operation in areas where low ambient temperature can occur together with high humidity conditions. In such conditions the units may experience problems with severe ice build up on the aircooled coil. In case such conditions are expected, the heater tape option OP10 must be installed instead.

■ Possible options

EWA/YQ_AC*P	—	—
EWA/YQ_AC*P-H-	Factory mounted	—
EWA/YQ_AC*H	—	Factory mounted
EWA/YQ_AC*H-H-	Factory mounted	Factory mounted

(a)Heater tape option OP10

(b)High ESP pump

Handling

Due to relatively large dimensions and high weight, the handling of the unit is only to be done by means of lifting tools with slings. These slings can be fitted into specially for this purpose foreseen sleeves at the base frame.

■ To avoid injury, do not touch the air inlet or aluminium fins of the unit.

■ Do not use the grips in the fan grills to avoid damage.

-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.

2When 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 causes 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.

5If 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.

6When installing the unit in a place frequently exposed to snow, pay special attention to elevate the foundation as high as possible.

7If you install the unit on a building frame, please install a waterproof plate (field supply)(within 150 mm of the underside of

the unit). (See figure).

Selecting a location in cold climates

Refer to "Model" on page 3.

CAUTION

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 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).

1 Construct a large canopy.

2 Construct a pedestal.

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

Make sure there is enough room to do the installation

■Set the outlet side at a right angle to the direction of the wind.

PRECAUTIONS ON INSTALLATION

■Check the strength and level of the installation ground so that the unit will not cause any operating vibration or noise after installation.

■In accordance with the foundation drawing in the figure, fix the unit securely by means of the foundation bolts. (Prepare four sets of M12 foundation bolts, nuts and washers each which are available on the market.)

■It is best to screw in the foundation bolts until their length are 20 mm from the foundation surface.

3Prepare a water drainage channel around the foundation, to drain waste water from around the unit.

4If 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).

Precaution

(A) In case of non-stacked installation (See figure 1)

	Suction side obstacle			Obstacle is present
	Discharge side obstacle	1		In these cases, close the
				bottom of the installation
				frame to prevent the
	Left side obstacle			discharged air from
				being bypassed
	Right side obstacle	2		In these cases, only
				2 units can be installed.
	Top side obstacle			This situation is not
				allowed
NOTE	Minimum distance	B1 in		figure 1 mentions the
	space required for correct operation of the unit.
	Required space for servicing though is 300 mm.

■Pump operation and heating and cooling (cooling and heating application with a room thermostat suitable for cooling/heating changeover connected to the unit)

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

The ON/OFF setting of the heating/cooling operation is done by the room thermostat and cannot be done by the user interface on the unit.

Make sure to connect the thermostat wires to the correct terminals (see "Connection of the thermostat cable" on page 13).
