2 Specific installer safety

instructions

Always observe the following safety instructions and regulations.

Installation site (see "4.1Preparing the installation site"[46])

WARNING

The appliance shall be stored in a room without continuously operating ignition sources (example: open flames, an operating gas appliance or an operating electric heater).

WARNING

DO NOT reuse refrigerant piping that has been used with any other refrigerant. Replace the refrigerant pipes or clean thoroughly.

NOTICE

▪ Pipework shall be protected from physical damage.

▪ Installation of pipework shall be kept to a minimum.

NOTICE

▪ Do NOT re-use joints which have been used already.

▪ Joints made in installation between parts of refrigerant

system shall be accessible for maintenance purposes.

WARNING

Make sure installation, servicing, maintenance and repair comply with instructions from Daikin and with applicable legislation (for example national gas regulation) and are executed only by authorised persons.

NOTICE

Do NOT tilt the unit forwards:

Piping installation (see "5Piping installation"[411])

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.

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).

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.

NOTICE

It is recommended to install shut-off valves to domestic cold water in and domestic hot water out connections. These shut-off valves are field supplied.

NOTICE

WARNING

▪ Do NOT pierce or burn.

▪ Do NOT use means to accelerate the defrosting

process or to clean the equipment, other than those recommended by the manufacturer.

▪ Be aware that R32 refrigerant does NOT contain an

odour.

WARNING

The appliance shall be stored so as to prevent mechanical damage and in a well-ventilated room without continuously operating ignition sources (example: open flames, an operating gas appliance or an operating electric heater) and have a room size as specified below.

Installation manual

Overpressure bypass valve (delivered as accessory). We recommend to install the overpressure bypass valve in the space heating water circuit.

Mind the minimum flow rate when adjusting the overpressure bypass valve setting. See "5.2.1 To check

the water volume and flow rate"[411] and "8.2.1To check the minimum flow rate"[433].

NOTICE

Do NOT use excessive force when connecting the piping. Deformation of the piping can cause malfunctioning of the unit.

NOTICE

Install air purge valves at all local high points.

NOTICE

A pressure relief valve (field supply) with an opening pressure of maximum 10bar (=1MPa) must be installed on the domestic cold water inlet connection in accordance with the applicable legislation.

2 Specific installer safety instructions

Electrical installation (see "6Electrical installation"[412])

DANGER: RISK OF ELECTROCUTION

WARNING

Make sure that the electrical wiring does NOT touch the refrigerant gas pipe, which can be very hot.

a Refrigerant gas pipe

WARNING

ALWAYS use multicore cable for power supply cables.

NOTICE

Do NOT cut or remove the backup heater power supply cable.

CAUTION

To guarantee the unit is completely earthed, always connect the backup heater power supply and the earth cable.

WARNING

The backup heater MUST have a dedicated power supply and MUST be protected by the safety devices required by the applicable legislation.

NOTICE

Wiring is different for a NC (normally closed) valve and a NO (normally open) valve.

NOTICE

Make sure to select and install the safety thermostat according to the applicable legislation.

In any case, to prevent unnecessary tripping of the safety thermostat, we recommend the following:

▪ The safety thermostat is automatically resettable.

▪ The safety thermostat has a maximum temperature

variation rate of 2°C/min.

▪ There is a minimum distance of 2m between the safety

thermostat and the 3‑way valve.

Configuration (see "7Configuration"[422])

NOTICE

This chapter explains only the basic configuration. For more detailed explanation and background information, see the installer reference guide.

NOTICE

NOT configuring the system in the following way can cause damage to the heat emitters. If there are 2 zones, it is important that in heating:

▪ the zone with the lowest water temperature is

configured as the main zone, and

▪ the zone with the highest water temperature is

configured as the additional zone.

NOTICE

If there are 2 zones and the emitter types are wrongly configured, water of high temperature can be sent towards a low temperature emitter (underfloor heating). To avoid this:

▪ Install an aquastat/thermostatic valve to avoid too high

temperatures towards a low temperature emitter.

▪ Make sure you set the emitter types for the main zone

[2.7] and for the additional zone [3.7] correctly in accordance with the connected emitter.

NOTICE Average emitter temperature = Leaving water

temperature – (Delta T)/2

This means that for a same leaving water temperature setpoint, the average emitter temperature of radiators is lower than that of underfloor heating because of a bigger delta T.

Example radiators: 40–10/2=35°C Example underfloor heating: 40–5/2=37.5°C

To compensate, you can:

▪ Increase the weather-dependent curve desired

temperatures [2.5].

▪ Enable leaving water temperature modulation and

increase the maximum modulation [2.C].

NOTICE

If an external room thermostat is used, the external room thermostat will control the room frost protection. However, the room frost protection is only possible if [C.2] Space heating/cooling=On.

WARNING Air purging heat emitters or collectors. Before you

purge air from heat emitters or collectors, check if or

is displayed on the home screen of the user interface.

▪ If not, you can purge air immediately.

▪ If yes, make sure that the room where you want to

purge air is sufficiently ventilated. Reason: Refrigerant might leak into the water circuit, and subsequently into the room when you purge air from the heat emitters or collectors.

NOTICE

To perform an underfloor heating screed dryout, room frost protection needs to be disabled ([2‑06]=0). By default, it is enabled ([2‑06]=1). However, due to the "installer-on-site" mode (see "Commissioning"), room frost protection will be automatically disabled for 36 hours after the first power-on.

If the screed dryout still needs to be performed after the first 36 hours of power-on, manually disable room frost protection by setting [2‑06] to "0", and KEEP it disabled until the screed dryout has finished. Ignoring this notice will result in cracking of the screed.

NOTICE

For the underfloor heating screed dryout to be able to start, make sure the following settings are met:

▪ [4‑00]=1

▪ [C‑02]=0

▪ [D‑01]=0

▪ [4‑08]=0
