INSTALLATION OF THE EKHWSU DOMESTIC
HOT WATER TANK
■The total AD system is designed for
combination with an AD domestic hot water tank. In case another tank or a spare part other than native Daikin is being used in combination with the AD unit, Daikin cannot guarantee neither good operation nor reliability of the system. For those reasons Daikin cannot give warranty of the system in such case.
■The equipment is not intended for use in a potentially explosive atmosphere.
■For safety reasons, it is not allowed to add ethylene glycol to the water circuit. Adding ethylene glycol might lead to contamination of the domestic water if a leakage would occur in the heat exchanger coil.
■Only this tank can be used in combination with the solar kit option.
■Domestic water quality must be according to EN directive 98/83 EC.
■It is important that the storage capacity of the domestic water tank meets normal daily fluctuations in consumption of hot water without any fall of the water outlet temperature during use.
■Immediately after installation, the domestic hot water tank must be flushed with fresh water. This procedure must be repeated at least once a day the first 5 consecutive days after installation.

Safety devices
■The domestic hot tank relief valve connections should
not be used for other purposes.
■Do not install heaters without thermal cut-outs.
■Thermal protector — The booster heater in the domestic hot water tank is equipped with a thermal protector (setting 85°C).
■For EKUHW2WB only: Secondary thermal protector (solenoid 2-way valve) — The thermal protector will close the solenoid 2-way valve (setting 85°C).
Both thermal protectors are activated when the temperature becomes too high. When activated, the protectors have to be reset on the domestic hot water tank by pressing the red button (for access, remove the electrical box lid).
The electrical box lid must only be opened by a licensed electrician.
Switch off the power supply before opening the electrical box lid.
■For EKUHW2WB only: Thermostat (solenoid 2-way valve)
The thermostat will close the solenoid 2-way valve when the temperature becomes too high (setting 79°C).
■Temperature and pressure relief valve
The temperature and pressure relief valve prevents excessive water temperature (>95°C) and excessive water pressure (≥10 bar) in the domestic hot water tank.
■Expansion relief valve (option kit)
The pressure relief valve prevents excessive water pressure (≥8 bar) in the water circuit.
NOTE |
Refer to "Installation of the option kit on the domestic |
|
hot water tank" on page 9 for connection of other |
|
safety devices in accordance with relevant local and |
|
national regulations. |

Domestic hot water tank with option kit for air to water heat pump system
4PW44439-1D – 02.2011
Installation guidelines
Keep in mind the following guidelines when installing the domestic hot water tank:
■The installation location is frost-free.
■Make sure to make the piping in size 1" or more (and reduce to 3/4" at the inlet of the tank) as to have sufficient water volume in the piping between unit and domestic hot water tank.
■Locate the domestic hot water tank in a suitable position to facilitate easy maintenance; remember access is required to the electrical box. Refer to the grey zones in the outlook diagram.
■ The domestic hot water tank model EKHWSU150B3V3 can be floor or wall mounted. In case of wall mounting, wall mounting kit EKWBSWW150 is required (separate ordering).
■If installing an EKHWSU* domestic hot water tank, installing the option kit EKUHWB is obligatory. Refer to the UK Building
Regulation G3.
■If installing the kit EKSOLHWAV1, installing the option kit EKUHW2WB is obligatory.
■Take care that in the event of a leak, water cannot cause any damage to the installation space and surroundings
Installing the domestic hot water tank
1Check if all domestic hot water tank accessories (see "Accessories" on page 2) are enclosed.
2When floor mounting, place the domestic hot water tank on a level surface. When wall mounting (only for EKHWSU150B3V3 model), make sure the wall is sturdy. In both cases, make sure the tank is mounted level.
3Apply thermal paste to the thermistor and insert the thermistor as deep as possible in the thermistor socket. Fix using the nut provided.
Connecting the water circuits
Refer to the chapter “Typical application examples” described in the installation manual delivered with the unit for details on connecting the water circuits and the motorised 3-way valve.
