Installation manual

Daikin Altherma – Low temperature split

EHBH/X04+08DA

4P495266-1C – 2018.11

3 Preparation

Input from installer:

▪ Total refrigerant charge (m

) (kg) ▪ Installation height (H) (m) ▪ Area of room A (A

room A

) (m2)

Start

Use table 1 in chapter "Technical data" to calculate the maximum refrigerant charge (m

max

) (kg) allowed for room A.

Contact your dealer.

Use table 3 in chapter "Technical data" and dm to calculate the minimum opening area for natural ventilation between room A and

room B (VA

min

) (cm2).

Unit can be installed at room A if: ▪ 2 ventilation openings (permanently open) are provided between room A and B, 1 at the top and 1 at the bottom. ▪ Bottom opening: The bottom opening must meet the minimum area requirements (VA

min

). It must be as close as possible to the floor and lower than H. If the ventilation opening starts from the floor, the height must be ≥20 mm. The bottom of the opening must be situated ≤100 mm from the floor. At least 50% of the required opening area must be situated <200 mm from the floor. The entire area of the opening must be situated <300 mm from the floor.

▪ Top opening: The area of the top opening must be larger than or equal to the bottom opening. The bottom of the top opening must be situated at least 1.5 m

above the top of the bottom opening.

▪ Ventilation openings to the outside are NOT considered suitable ventilation openings (the user can block them when it is cold).

The unit can be installed in room A at the specified installation height, and without further room size or ventilation requirements.

Determine the refrigerant amount that exceeds

max

(dm) (kg). (dm=mc–m

max

)

max≥mc

Yes

Use table 2 in chapter "Technical data" to calculate the total minimum floor area (A

min total

) (m2) required for the total refrigerant

charge (m

) at the selected installation height

(H).

a Indoor unit A Room where the indoor unit is installed. B Room adjacent to room A.

min total≤Aroom A+Aroom B

Yes

Input from installer:

▪ Area of adjacent room B (A

room B

) (m2)

≥1.5 m

If the total refrigerant charge in the system is ≥1.84kg (i.e. if the piping length is ≥27m), you need to comply with the minimum floor area requirements as described in the following flow chart. The flow chart uses the following tables: "8.3 Table 1 – Maximum refrigerant charge

allowed in a room: indoor unit" on page28, "8.4 Table 2 – Minimum floor area: indoor unit"on page28 and "8.5Table 3 – Minimum venting opening area for natural ventilation: indoor unit"on page28.

INFORMATION

Systems with a total refrigerant charge (mc) <1.84kg (i.e. if the piping length is <27 m) are NOT subjected to any requirements to the installation room.

INFORMATION Multiple indoor units. If two or more indoor units are

installed in a room, you must consider the maximum refrigerant charge that can be released in the room when a SINGLE leak occurs. Example: If two indoor units are installed in the room, each with its own outdoor unit, then you have to consider the refrigerant charge of the largest indoor-outdoor combination.

Installation manual

4 Installation

3.2 Preparing water piping

NOTICE

In case of plastic pipes, make sure they are fully oxygen diffusion tight according to DIN 4726. The diffusion of oxygen into the piping can lead to excessive corrosion.

▪ Valve towards expansion vessel. The valve towards the

expansion vessel (if equipped) MUST be open.

3.2.1 To check the water volume and flow rate

Minimum water volume

Check that the total water volume in the installation is minimum 10litres, the internal water volume of the indoor unit NOT included.

NOTICE

When circulation in each space heating/cooling loop is controlled by remotely controlled valves, it is important that the minimum water volume is guaranteed, even if all of the valves are closed.

Minimum flow rate

Check that the minimum flow rate in the installation is guaranteed in all conditions. This minimum flow rate is required during defrost/ backup heater operation. For this purpose, use the overpressure bypass valve delivered with the unit, and respect the minimum water volume.

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 or operation).

See the installer reference guide for more information.
