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

4.6 Hydraulic installation

The AQtap must be supplied with water via a pipe
Caution
with 1/2" inner diameter, not via a hose.
The strainer must be installed in front of the
AQtap to prevent particles from entering the unit.
Caution
The strainer must be kept clean.
The galvanic separator (hydraulic part) must be
installed in front of the strainer to avoid galvanic
Caution
effects (damages) in the AQtap.
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 for the connection of a pipe and an outlet
for a hose or a pipe with an external thread of 1/2".
A strainer and a galvanic separator must be installed at the inlet.
Both are included in the product delivery.
A shut-off device must be installed in front of the AQtap for
servicing needs. If the inlet water pressure can exceed the
allowed value, an elevated break tank must be installed in front of
the AQtap. The shut-off device is available as accessories.
Observe section Water supply requirements.
The AQtap water dispenser can be connected to an existing main
water grid or a water tank. The water tank must be high enough
for gravity feed. The tank outlet should be more than 3 m above
the AQtap inlet. If this is not possible, Grundfos can provide a
booster pump. The water outlet should be at the tank side to
avoid sediment entering the AQtap. Construct the tank installation
in 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
Note
Teflon, hemp or similar resistant seal material.
If a pressure relief valve is used, mount the
pressure relief valve with sealed threads directly
to the water inlet of the AQtap. See the
Note
installation and operating instructions supplied
with the pressure relief 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 ½" external
thread of the water outlet.
2. Mount the galvanic separator to the strainer:
– seal the thread and screw the galvanic separator into the
inlet of the strainer, see arrow on the strainer.
3. Connect the water inlet:
– remove the protection cap from the water inlet,
– seal the thread and screw the strainer together with the
galvanic separator onto the ½" external thread of the water
inlet,
– seal the tread of the galvanic separator and connect the
water inlet,
– keep the shut-off valve closed until the AQtap cabinet is
locked after installation.
4. Check that the connections are tight, mounting torque:
– strainer: 30 ±3Nm
– galvanic separator: 10 ±1Nm

4.7 SIM card preparation and installation

Switch off the power supply, both grid and solar,
and disconnect the battery before inserting the
Caution
SIM card. 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
Note
connection time.
The AQtap is operable without SIM card, see
7.10.5 Operating of offline AQtaps. This manual
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.
6. 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 a way that it fits in the mould of the
slide.
– Slide the SIM card into the slot.

4.8 Electrical connection

4.8.1 Safety instructions
DANGER
Electric shock
• Switch off the power supply, both grid and
solar, before making any connections.
• The AQtap cabinet must only be opened by
authorised and qualified staff.
• All electrical connections must be carried out
by a qualified electrician in accordance with
local regulations.
• Stripped parts of wires must not protrude from
terminals.
DANGER
Electric shock
• AQtap with grid power supply must be
connected to an external mains switch with a
minimum contact gap of 3 mm in all poles.
• If an AQtap with grid power supply is
connected to an electric installation where an
earth leakage circuit breaker (ELCB) is used as
an additional protection, this ELCB must trip
when earth fault currents with DC content
(pulsating DC) occur. The ELCB must be
marked either with the left symbol or with both
symbols shown below.
We recommend to use armoured cables or run
Caution
cables in conduits on the outside of the AQtap.
