INFORMATION: ABOUT THE CONTROL BOX, OPTION BOX, AND BACKUP HEATER INSTALLATION MANUALS

EWAQ004+005BAVP and EWYQ004+005BAVP systems do NOT support domestic hot water and heat pump convector functionalities. In the installation manual of the control box, option box, and backup heater, therefore any reference to "domestic hot water", "domestic hot water tank", "booster heater", and "heat pump convector", may be disregarded.

Latest revisions of the supplied documentation may be available on the regional Daikin website or via your dealer.

The original documentation is written in English. All other languages are translations.

2 About the box

2.1 Outdoor unit

2.1.1 To remove the accessories from the outdoor unit

1 Open the outdoor unit.

INFORMATION

The instruction sheet for valve kit EKMBHBP1 only applies in case valve kit EKMBHBP1 is part of the system. If so, do NOT take into account the instruction sheet delivered with the valve kit; it is overruled by the one delivered with the outdoor unit.

3 Preparation

3.1 Preparing installation site

3.1.1 Installation site requirements of the outdoor unit

Mind the following spacing guidelines:

a Air outlet b Air inlet

INFORMATION

If shut-off valves are installed on the unit, provide a minimum space of 400mm at the air inlet side. If shut‑off valves are NOT installed on the unit, provide a minimum space of 250mm.

Do NOT install the unit in sound sensitive areas (e.g. near a bedroom), so that the operation noise will cause no trouble.

Note: If the sound is measured under actual installation conditions, the measured value might be higher than the sound pressure level mentioned in Sound spectrum in the data book due to environmental noise and sound reflections.

2 Remove the accessories.

f Sealing ring for shut-off valve g Shut-off valve h Unit mounting plate

i User interface

Installation manual

INFORMATION

The sound pressure level is less than 70dBA.

The outdoor unit is designed for outdoor installation only, and for ambient temperatures ranging 10~43°C in cooling mode and – 20~25°C in heating mode.

Minimum flow rate

Check that the minimum flow rate (required during defrost/backup heater operation) in the installation is guaranteed in all conditions.

NOTICE

If glycol was added to the water circuit, and the

temperature of the water circuit is low, the flow rate will

NOT be displayed on the user interface. In this case, the

minimum flow rate can be checked by way of the pump

test (check that the user interface does NOT display error

7H).

NOTICE

When circulation in each or certain space heating loops is

controlled by remotely controlled valves, it is important that

the minimum flow rate is guaranteed, even if all valves are

closed. In case the minimum flow rate cannot be reached,

a flow error 7H will be generated (no heating/operation).

See the installer reference guide for more information.

From the control box installation manual (same chapter), disregard the following items:

▪ 9 – 3‑way valve ▪ 10 – Power supply for booster heater and thermal

protection (from control box)

▪ 11 – Power supply for booster heater (to control box) ▪ 12 – Domestic hot water tank thermistor ▪ 13 – Heat pump convector

INFORMATION

The maximum height of the upper protruding part of the bolts is 15mm.

In any case, provide at least 300mm of free space below the unit. Additionally, make sure the unit is positioned at least 100mm above the maximum expected level of snow.

1 Lift the outdoor unit.

2 Install the outdoor unit as follows:

NOTICE

To prevent damage to the supporting feet, do NOT tilt the unit sideways in any way:

4.2.3 To provide drainage

Make sure that condensate can be evacuated properly. When the unit is in cooling mode, condensate may also form in the hydro part. When providing drainage, therefore make sure to cover the entire unit.

NOTICE

If the unit is installed in a cold climate, take adequate measures so that the evacuated condensate cannot freeze.

INFORMATION

For information on the available options, contact your dealer.

NOTICE

Properly align the unit. Make sure the backside of the unit does NOT protrude.

3 Remove the protective cardboard and instruction sheet.

Provide at least 300 mm of free space below the unit. Additionally, make sure the unit is positioned at least 100mm above the expected level of snow.

4.2.4 To prevent the outdoor unit from falling over

1 Prepare 2 cables as indicated in the following illustration (field

supply).

2 Place the 2 cables over the outdoor unit. 3 Insert a rubber sheet between the cables and the outdoor unit

to prevent the cable from scratching the paint (field supply).

4 Attach the cable’s ends. Tighten those ends.

4.3 Connecting the water piping

4.3.1 To connect the water piping

NOTICE

Do NOT use excessive force when connecting the piping. Deformation of the piping can cause malfunctioning of the unit. Make sure that the tightening torque does NOT exceed 30N•m.

To facilitate service and maintenance, 2 shut-off valves are provided. Mount the valves on the water inlet and on the water outlet. Mind their position: the integrated drain valves will only drain the side of the circuit on which they are located. To be able to only drain the unit, make sure the drain valves are positioned between the shut‑off valves and the unit.

1 Screw the outdoor unit nuts on the shut-off valves. 2 Connect the field piping on the shut-off valves.

NOTICE

Install a manometer in the system.

NOTICE

Install air purge valves at all local high points.

4.3.2 To protect the water circuit against freezing

If negative outdoor temperatures are expected, add glycol to the water circuit. The required concentration depends on the lowest expected outdoor temperature, and on whether you want to protect the system from bursting or from freezing. To prevent the system from freezing, more glycol is required. Add glycol according to the table below.

INFORMATION

▪ Protection against bursting: the glycol will prevent the

piping from bursting, but NOT the liquid inside the piping from freezing.

▪ Protection against freezing: the glycol will prevent the

liquid inside the piping from freezing.

Lowest expected outdoor temperature

–20°C 25% — –25°C 30% —

NOTICE

▪ The addition of glycol applies to BOTH cooling‑only

models (EWAQ004+005BAVP) AND reversible models (EWYQ004+005BAVP), and is independent of cooling or heating operation. ALWAYS add glycol if negative outdoor temperatures are expected.

▪ The required concentration might differ depending on

the type of glycol. ALWAYS compare the requirements from the table above with the specifications provided by the glycol manufacturer. If necessary, meet the requirements set by the glycol manufacturer.

▪ The added concentration of glycol should NEVER

exceed 35%.

▪ If the liquid in the system is frozen, the pump will NOT

be able to start. Mind that if you only prevent the system from bursting, the liquid inside might still freeze.

▪ In case of a power supply failure or pump failure, and

NO glycol was added to the system, drain the system.

▪ When water is at standstill inside the system, the

system is very likely to freeze and get damaged.

The following types of glycol are allowed: ▪ Ethylene glycol; ▪ Propylene glycol, including the necessary inhibitors, classified as

CategoryIII according to EN1717.

WARNING

Ethylene glycol is toxic.

NOTICE

Glycol absorbs water from its environment. Therefore do NOT add glycol that has been exposed to air. Leaving the cap off the glycol container causes the concentration of water to increase. The glycol concentration is then lower than assumed. As a result, the hydraulic components might freeze up after all. Take preventive actions to ensure a minimal exposure of the glycol to air.

NOTICE

▪ If overpressure occurs, the system will release some of

the liquid through the pressure relief valve. If glycol was added to the system, take adequate measures so as to safely recover it.

▪ In any case, make sure that the flexible hose of the

pressure relief valve is ALWAYS free to release pressure. Prevent water from staying and/or freezing up inside the hose.
