2. GENERAL SAFETY PRECAUTIONS

The precautions here, all cover very important topics, so be sure to follow them carefully.

All activities described in this manual shall be carried out by an installer and in accordance with the applicable legislation.

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.

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

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

■ 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

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

■ This appliance is not intended for use by persons, including children, with reduced physical, sensory or mental capabilities, or lack of experience and knowledge, unless they have been given supervision or instruction concerning use of the appliance by a person responsible for their safety. Children should be supervised to ensure that they do not play with the appliance.

3. INTRODUCTION

4. ACCESSORIES

3.1. General information

Thank you for purchasing this EKSOLHTBV1 solar kit. The solar kit must be installed by a competent person and be

installed in compliance with the instructions in this manual. The solar kit is to be connected to the EKHV(H/X)* indoor units in

combination with the EKHTS* domestic hot water tanks. The solar kit will enable you to heat up your domestic water by means

of the sun whenever the sun is available. To get the most comfort and energy savings out of your system,

make sure to observe the section "10.1. Conﬁguring your system" on

page 12 of this manual.

3.2. Scope of this manual

This installation manual describes the procedures for installing and operating the EKSOLHTBV1 solar kit.

INFORMATION

Refer to the installation manual of the indoor unit for items not described in this manual.

The operation of the indoor unit is described in the indoor unit operation manual.

Domestic hot water tank tank thermal cut out

The solar kit is designed to transfer the heat from the Daikin solar panels to the heat exchanger of the domestic hot water tank EKHTS* and is to be installed in the system as shown in the scheme below.

Example of unit

3.2

3.3

The solar kit contains a thermal cut out safety device to be mounted on the domestic hot water tank casing. (refer to "7.6. Field wiring" on

page 8).

When the thermal cut out safety of the domestic hot water trips, the power supply to the pump of the solar kit is interrupted (and the solenoid 2-way valve (EKUHT2WB for UK-only) is closed) so that no more solar heat can be transferred to the domestic hot water tank. Error code AA will apear on the remote controller, refer to "11.3. Error

codes" on page 14.

Piping thermal cut out

Mounted on the piping of the solar kit, a thermal cut out safety protects the piping of the unit and domestic hot water tank against overheating.

When the thermal cut out safety of the piping trips, the power supply to the pump of the solar kit is interrupted (and the solenoid 2-way valve (EKUHT2WB for UK-only) is closed) so that no more solar heat can be transferred to the domestic hot water tank. There will apear no error code on the remote controller. Reset by pressing the reset button.

The solar panels (1) catch the heat of the sun. When the temperature of the glycol solution in the solar panel has become higher than the water temperature in the domestic hot water tank, the pump of the solar pump station (2) and the pump of the solar kit (4) start to operate as to transfer the heat to the heat exchanger of the domestic hot water tank, unless priority is given to the heat pump. Refer to

"10. Operating instructions" on page 12 (subsection: Conﬁguring your system).

7. INSTALLATION OF THE SOLAR KIT

7.1. Selecting an installation location

■ The solar kit is to be installed in a frost free indoor space, directly connected to the domestic hot water tank.

■ Make sure the service space is available as indicated in below drawing.

■ The space around the unit has to allow sufﬁcient air circulation.

■ It shall be made sure that in the case of a leak, leaking water will

not cause any damage or unsafe situations.

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

■ Do not install or operate the unit in rooms mentioned below:

- Where corrosive gas like sulphurous gas exists: copper

tubing and brazed spots may corrode.

- Where volatile ﬂammable gas like thinner or gasoline is used.

- Where machines generating electromagnetic waves exist:

the control system may malfunction.

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

ocean and where voltage ﬂuctuates a lot (e.g. in factories). This applies also to vehicles or vessels.

7.2. Dimensions and service space

Service space dimensions below relate to requirements for installation of the solar kit only. For service space dimensions of the domestic hot water tank, refer to the installation manuals of the domestic hot water tank and of the indoor unit.

7.3. Inspecting, handling and unpacking the unit

■ The EKSOLHTBV1 kit is packed in a cardboard box.

■ At delivery, the kit must be checked and any damage must be

reported immediately to the carrier claims agent.

■ Check if all accessories (see "4. Accessories" on page 3) are enclosed.

■ Bring the kit as close as possible to its ﬁnal installation position in its original package in order to prevent damage during transport.

CAUTION
