Installation

3.1Preparing installation site

3.1.1Installation site requirements of the domestic hot water tank kit

INFORMATION

The domestic hot water tank kit is mounted into the indoor unit. The use of tank kit EKVSU260A extends the height of the indoor unit by 190 mm.

3.2Preparing water piping

Respect the following water circuit requirements:

▪Domestic hot water tank kit – Clean pipes. Before installing the domestic hot water tank kit, all piping and fittings must be flushed free of flux and debris. Failure to do this may cause irreparable damage to the tank kit control valves. Flush the system by opening the hot water tap.

▪Domestic hot water tank kit – Drainage. For the discharge piping connected to the pressure relief valve of the domestic hot water tank kit, respect the following requirements:

Item	Requirement
Pressure relief valve diameter	15 mm
Discharge pipe diameter (to pressure relief valve)	15 mm
Discharge piping diameter (from tundish)	22 mm
Discharge piping material (from tundish)	Metal
Vertical length below tundish, before first elbow or	≥300 mm
bend
Continuous fall after first elbow or bend	≥1:200
Maximum resistance(a)	≤9 m
Resistance created by each elbow or bend	0.8 m

(a)The maximum allowed resistance (i.e. equivalent length) is expressed as a length of straight pipe (i.e. no elbows or bends).

INFORMATION

All piping MUST be installed according to section G3 of the Building Regulations.

▪Domestic hot water tank kit – Pressure balancing. To prevent large pressure differences at the taps and damage to the shower valve due to high pressure cold water (5 bar), provide a dedicated 2 bar feed to both cold water and hot water taps. To do this, also connect the cold water supply for the cold water taps to the pressure reducing valve of the domestic hot water tank kit.

4.2.1To connect the water piping

NOTICE

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

INFORMATION

If you have to inspect the inside of the domestic hot water tank, you can access it via the booster heater boss.

The installation of the domestic hot water tank kit is part of a larger installation flow. The total installation of the water piping consists of:

1Connecting the recirculation piping.

2Connecting the water piping:

▪Directly to the indoor unit: connecting the water piping to the space heating inlet, the space heating outlet, and the domestic hot water outlet.

▪Via the domestic hot water tank kit: connecting the water piping to the unit’s domestic cold water inlet, and connecting the kit itself to the drain.

3Connecting the pressure relief valve to the drain.

4Filling the water circuit.

5Filling the domestic hot water tank.

6Insulating the water piping.

INFORMATION

For more information, see the installation manual of the indoor unit and the installer reference guide.

▪Domestic hot water tank kit – Secondary return. Where the secondary return circuits are used, an additional expansion vessel may be required.
