Hydraulic Installation; Sim Card Preparation And Installation - Grundfos AQtap Installation And Operating Instructions Manual

4.6 Hydraulic installation

The AQtap must be supplied with water via a pipe
Caution
with 3/4" inner diameter, not via a hose.
The galvanic separator (hydraulic part) must be
installed in front of the AQtap to avoid galvanic
Caution
effects (damages) in the unit.
The strainer must be installed in front of the AQtap to
prevent particles from entering the unit. The strainer
must be installed horizontally with the filter piece
Caution
pointing downwards. The strainer must be kept
clean.
Install and operate the AQtap in accordance with
national health and safety regulations, or any
Note
national rules that may be applicable.
The AQtap has an inlet with an external thread of 1/2". A galvanic
separator functions as reducing piece between 3/4" water supply
pipe with accessories and the inlet at the AQtap.
The AQtap has an outlet with an external thread of 1/2" to
connect a hose or a pipe.
The galvanic separator and a strainer must be installed at the
inlet. Both are included in the product delivery. Use a 90 ° elbow,
3/4" to connect the strainer to the galvanic separator. The strainer
must be installed horizontally with the filter piece pointing
downwards.
A shut-off device must be installed in front of the AQtap for
maintenance and service needs (available as an accessory).
If the inlet water pressure can exceed the allowed value, a
pressure reducing valve or an elevated break must be installed in
front of the AQtap.
If a non-return valve is installed in the water supply line, a
pressure relief valve must be installed in front of the AQtap.
Observe section
Water supply
The AQtap water dispenser can be connected to an existing main
water grid or a water tank. Minimise the number of bends in the
water supply line, in order to avoid water flow reduction. The tank
must be high enough for gravity feed. It is recommended that the
tank outlet is at least 3 m above the AQtap inlet. If this is not
possible, Grundfos can provide a booster pump. The tank should
have a lateral water outlet to avoid sediment entering the AQtap.
Install the tank in such a way that it can be emptied and cleaned.
Hydraulic connection
Leaking pipe connections will affect the efficiency of
the system. Seal the threads with PTFE, hemp or
Note
similar resistant seal material.
If a pressure reducing valve is used, see the
installation and operating instructions supplied with
Note
the pressure reducing valve.
1. Connect the water outlet:
– Remove the protection cap from the water outlet.
– Connect a hose or pipe with a union nut to the 1/2" external
thread of the water outlet.

requirements.
2. Connect the water inlet:
– Remove the protection cap from the water inlet.
– Seal the thread and screw the galvanic separator onto the
1/2" external thread of the water inlet.
– Seal the thread and screw the 90 ° elbow onto the 3/4"
external thread of the galvanic separator.
– Seal the thread and screw the strainer onto the 3/4" external
thread of the 90 ° elbow in correct orientation. See arrow
indicating the flow direction on the strainer.
– Seal the thread of the strainer and connect the water inlet.
– Keep the shut-off valve closed until the AQtap cabinet is
locked after installation.
3. Check that the connections are tight, mounting torque:
– strainer: 30 ± 3Nm
– galvanic separator: 10 ± 1 Nm.

4.7 SIM card preparation and installation

Switch off the power supply, both grid and solar, and
disconnect the battery before inserting the SIM card.
Caution
The SIM card will not be read by the AQtap until it
was powered off and on again.
Disable the PIN protection of the SIM card. PIN
Caution
protected SIM cards lead to malfunction.
Connect the AQtap to GSM network before creating
it in WMS. This can reduce the speed connection
Note
time.
The AQtap is operable without SIM card, see section
7.10.5 Operating of offline
Note
assumes normal operation of AQtaps with
connection to WMS.
1. Conclude a mobile subscription with an approved mobile
phone operator (telco).
– Mini-SIM card (15 x 25 mm)
– 2G machine-to-machine GPRS data subscription
– Ability to send and receive international SMS messages
– Ability to acquire a signal from the network operator you
expect it to use
– GPRS data subscription of 10 MB per month with automatic
top-up
2. Insert the SIM card into a mobile phone, and set the "PIN
code request" option to "OFF".
3. Write down the following:
– Mobile phone number of the SIM card.
– IMEI number of the CIM. The number is written on the
sticker on the back side of the control unit.
4. Insert the SIM card into the CIM of the power-off AQtap. The
SIM card will only be read after power-on.
– Place the SIM card in the mould of the slide.
– Slide the SIM card into the slot.
