9.0 INSTALLATION – ELECTRICAL REQUIREMENTS
9.1 WARNING: THIS APPLIANCE MUST BE EARTHED. IT IS SUITABLE FOR A
230 / 240 V ~ SUPPLY ONLY.
9.2 Installation must be carried out by a competent electrician in accordance with the latest
edition of BS 7671 (the IEE Wiring Regulations).
9.3 For Boil and Chill and Boil and Ambient installations, a control box is supplied with the
kit of parts. The heater unit must be wired through this control box to allow control of the
chilled or ambient water supply to the dispenser.
9.4 The control box unit is supplied fitted with a 1.5 metre electrical supply cable. If the cable
needs to be lengthened, this must be done by a qualified electrician using 3 core cable
with a minimum conductor cross sectional area of 1.5 mm². The electrical supply cable
must be connected to the electrical supply via a double pole isolating switch with a
contact separation of at least 3mm in both poles. The electrical supply should be fused
13 amp.
9.5 Fix the control box to a suitable surface near to the dispenser and Aquatap heater using
screws and wall plugs supplied.
9.6 The AQUATAP heater should be wired into the control box as Fig. 9, page 15. If
a chiller is also being used, this should be wired into the control box as Fig. 9,
page 15. NOTE: The chiller is supplied with a power cable fitted with a 3 pin plug. If
a second fused spur is available, use this supply. If only one fused spur is available,
remove the plug from the chiller power cable and strip back the wires. Wire up the chiller
as Fig. 9, page 15 ensuring that the live connection is wired up through the 3A fused
terminal connection.
9.7 The AQUATAP dispensing tap must be connected to the control box unit by means of
the black sheathed control cable. The cables from each unit are terminated in a mating
plug and socket which should be pushed firmly together to connect them.
9.8 Schematic wiring diagrams of the AQUATAP variant installation are shown in Fig. 7,
page 12, Fig. 8, page 13 and Fig.9, page 15.
9.8 If the AQUATAP is to be unused for significant periods of time, running costs can be
reduced by switching the unit off. It is recommended that this is done automatically by
incorporating a suitable time switch in the electrical supply to the unit. A suitable time
switch is available as an accessory (Product Code 95970124) which can be set to switch
the unit on for a suitable period of time to allow it to reheat before it is next used.
NOTE: If selecting an alternative time switch, it must be capable of switching a 13 amp
resistive load.
9.10 Please make sure all grommets are in place and any unsued holes are sealed to prevent
water ingress.
