Installation Guidelines; Installing The Solar Kit - Daikin EKSOLHWAV1 Manuel D'installation Et D'utilisation

Installation guidelines

Make sure that all the piping to the solar kit is insulated.
Make sure that all the piping to the solar kit is sufficiently
supported so that it will not cause any stress on the solar kit.
Make sure the piping is protected against dirt during installation.
Dirt in the piping might clog the heat exchanger of the solar
panel and reduce its performance.

Installing the solar kit

At delivery, the unit should be checked and any damage should
be reported immediately to the carrier claims agent.
Check if all unit's accessories are enclosed. Refer to
"Accessories supplied with the solar kit" on page 2.
Bring the unit as close as possible to its final installation position
in its original package in order to prevent damage during
transport.
Procedure
Refer to the installation drawings. The numbers on the drawings refer
to the steps described below.

1 Locate the domestic hot water tank in a suitable position to
facilitate the installation of the solar kit. It is therefore
recommended to first read the entire installation procedure.
Refer to the installation guidelines in the installation manual of
the domestic hot water tank.
EKHWS(U) only:
Fit the thermistor socket in the thermistor hole for the domestic
hot water temperature sensor of the solar pump station. (Refer
to "Accessories supplied with the solar kit" on page 2, part 1).
2 Refer to the corresponding sub-step, depending on your tank
capacity. For UK, refer to 2.3.
EKHW*200/300*:
2.1 Fit the adaptor 3/4" Female BSP x 3/4" Male BSP in the flow
inlet connection of the domestic hot water tank. Refer to
"Accessories supplied with the solar kit" on page 2, part 4.
2.2 Fit the connection pipe 3/4" Male BSP x 3/4" Male BSP and
sealing in the flow inlet connection of the domestic hot water
tank. Refer to "Accessories supplied with the solar kit" on
page 2, part 2 and 3.
EKHW*150*: Fit the connection pipe 3/4" Male BSP x 3/4"
Male BSP in the flow inlet connection of the domestic hot
water tank. Refer to "Accessories supplied with the solar kit"
on page 2, part 2.
EKHWSU*:
2.3 Fit the adaptor 3/4" Male BSP x 3/4" Male BSP (x2) in the
solenoid 2-way valve supplied as accessory with the
EKUHW* kit. Refer to "Accessories supplied with the solar
kit" on page 2, part 5.
2.4 Fit the solenoid 2-way valve in the flow inlet connection of
the domestic hot water tank.
The valve must be mounted so that the valve head is above
horizontal level of pipework to prevent that in the highly
unlikely event of a leak, a safety hazard results.
The valve must be mounted so that the valve head is
pointed to the front of the domestic hot water tank with the
cable entry at the bottom. Check direction of the flow arrow
cast on the solenoid valve body. Do not grip the valve head
while making and tightening up connections.

10 Mount the EPP lid onto the right side of the EPP casing.
11 Mount the right side of the EPP casing onto the solar kit.
12 Use the screws and washers (x2) to fix the EPP casing. Screw
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.
NOTE
For EKHW*150* only:
3.1 Unscrew the stop 3/4" Male on the return connection to the
150 l domestic hot water tank heat exchanger. Keep sealing.
3.2 Fit the stop 3/4" Male + sealing on the return connection to
the 200/300 l domestic hot water tank heat exchanger.
Fit the adaptor 3/4" Male BSP x 3/4" Male BSP in the heat
exchanger outlet connection of the domestic hot water tank.
Refer to "Accessories supplied with the solar kit" on page 2,
part 5.
For the EKHWSU150* (UK only): Fit a pipe 3/4" Male BSP x 3/4"
Male BSP in the heat exchanger outlet connection of the
domestic hot water tank (field supply, L = 50 mm).
Fit the solar kit and sealings (x2) on the heat exchanger inlet
connection and heat exchanger outlet connection of the
domestic hot water tank. Torque 5 N•m. Refer to "Accessories
supplied with the solar kit" on page 2, part 3.
Fit the adaptors 3/4" Male BSP x 3/4" Male BSP (x4) to the field
piping:
Inlet connection from the unit.
Return connection to the unit.
Inlet connection from solar pump station.
Return connection to solar pump station.
Refer to "Accessories supplied with the solar kit" on page 2,
part 5.
WARNING
Due to heat conduction, the piping between heating
circuit and solar kit connection can become very hot.
For this reason this pipe must be made of copper, at
least 0.5 m long and insulated.
Fit the solar kit and sealings (x4) to the field piping. Torque
5 N•m. Refer to "Accessories supplied with the solar kit" on
page 2, part 3.
For EKHWSU* (UK only): Cut out EPP material of the EPP lid.
Mount the left side of the EPP casing onto the solar kit.
Take care, that the pump cable is routed via the holes in the
bottom of the EPP casing.
Ensure that the pump cable cannot come into contact
with piping below the pump when cable is routed out.
until tight position.
Do not overtighten. Overtightening may damage the EPP
casing. The maximum allowed tightening torque is 1.5 N•m.
Do not switch inlet and outlet connections.
To install adequate connections between the unit and
the solar kit, it is important that the 3-way valve is fitted
correctly.
Ensure that the water piping connected to the solar kit
coming from the solar panel and the unit are sufficiently
supported and do not cause any stress on the solar kit.
