INTRODUCTION

General information

Thank you for purchasing this AD outdoor monoblock unit.

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 water heating applications and solar kit for domestic hot water applications.

Heating/cooling units and heating only units

The AD outdoor monoblock unit range consists of two main versions: a heating/cooling (EB) version and a heating only (ED) version.

Both versions are delivered with an integrated backup heater 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 waterpiping 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/2 kW. The backup heater capacity decision is a mode based on the equilibriumtemperature, see scheme below.

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.

E(D/B)(H/L)Q011~016AA6V3+W1	Installation manual
Unit for air to water heat pump system	2
4PW51121-1C

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.

Model

EDL and EBL 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 EDH and EBH models may experience problems with severe ice build up on the aircooled coil. In case such conditions are expected, the EDL or EBL must be installed instead. These models contain countermeasures (insulation, heater sheet,...) to prevent freeze up.

■Possible options

	Heater sheet	Drain socket
EDLQ, EBLQ	Standard	Use prohibited
EDHQ, EBHQ	Optional kit(a)	Optional kit(a)

(a) Combination of both options is prohibited.

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 specialy 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.

■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.

1Select 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 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.

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) or use a drain kit (refer to combination table in "Possible options" on page 3) in order to avoid the drainwater dripping. (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. Strong wind

Blown air

Strong wind

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).

4PW51121-1C

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 (8) can provide auxiliary heating.

It is possible to connect either a 2-wire or a 3-wire 3-way valve (6). Make sure to fit the 3-way valve correctly. For more details, refer to "Wiring the 3-way valve" on page 17.

NOTE	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 "Field settings" on page 21, field settings [5-02] to [5-04].

Application 3

Space cooling and heating application with a room thermostat suitable for cooling/heating changeover connected to the unit. Heating is provided through floor heating loops and fan coil units. Cooling is provided through the fan coil units only.
