Service Helpdesk.
IThe Zip Varipoint is an unvented water heater designed for connection
directly to the incoming mains water supply and can serve one or more
outlets using conventional taps.
ICare should be taken that the capacity of the unit chosen is sufficient to
meet the demands of the outlets being supplied.
IThe casing is constructed from impact resistant plastic and heat losses
are minimised by the CFC free polyurethane foam insulation.
IThe inner vessel is heavy gauge copper and pressure tested to 16 bar.
IAn alloy sheathed heating element provides longer life in aggressive water
conditions.
IA manually resettable safety cut-out automatically cuts off the electrical
supply to the heating element in the event of a malfunction.
If he ho -wa er sys em is no used for wo weeks or more,
i is recommended ha a ho ap be urned on for several
minu es a a sink, basin or ba h, bu no a a dishwasher,

Ins alla ion
Requirements
1 These instructions must be read and fully understood before commencing
the installation. f in doubt, or in need of further guidance please ring Zip
on 0845 602 4533.
2 Zip Varipoint unvented water heaters must be installed by a competent
installer, familiar with unvented electric water heaters.
3 nstallations must comply fully with UK Water Regulations and any Local
Authority requirements.
4 The electrical installation including earthing and cross bonding should
comply with the current EE regulations and any Local Authority
requirements.
5 The Zip Varipoint is designed for connection direct to the incoming mains
water supply and accommodation must be made for the expanded water
that will occur with each operating cycle. Regulations permit expanded
hot water to be accommodated within the supply pipework provided that
no check valve, stop valve with loose jumper or other fitting can prevent
reverse flow (diagram 1).
Where the expanded water cannot be accommodated in the pipe work
and the static water supply pressure is under 4 bar, fit accessory pack
AQ2 (Expansion vessel and check valve). Where static water pressures
are likely to exceed 4 bar, fit accessory packs AQ2 and AQ3 Pressure
reducing valve and line strainer. See diagrams 2 and 3.
6 The 6 bar expansion relief valve must be fitted on the cold water supply.
7 The T&P valve should be fitted to the boss provided.
8 The drain connection from the expansion relief valve and the T&P relief
valve, must be in accordance with Water Supply Regulations. The point of
discharge must be in a safe and visible position. The connection should
be made using 15 mm pipe having a continuous fall to a maximum length
of three metres. t should not have more than 3 right-angled bends. f a
waste connection in excess of three metres is necessary, the pipe
diameter should be 22 mm with a continuous fall and no more than four
right-angled bends to a maximum resistance to flow equivalent to 9
metres of straight pipe.
9 An solating valve must be fitted to the cold water supply.
10 Valves and fittings must be of a type required by Water Supply Regulations.

P siti ning
1 Depending upon the model chosen the Varipoint 2 can be installed over
or underbasin. The underbasin model is designed to be floor standing
with the connections uppermost, the hot supply (colour coded red) to
the left when facing the unit. A wall fixing bracket is supplied for use if
required.
2 The models to be sited overbasin are wall hung using the bracket
provided. Ensure that the wall supporting the product is sufficiently
strong to bear the weight of the unit when full. The connections are at
the bottom of the unit with the hot supply to the left when facing the unit.
Mark the position of the fixings AND BEFORE drilling into the wall ensure
that any hidden pipework or electrical wiring is avoided.
3 The dimensions, fixing positions and weights are shown in the Table that
appears on page 6.
4hen deciding the final location of the heater, consideration should
be given to the safe and visible disposal of any water resulting from
leaks or seepage. This is particularly relevant when the heater is
located in a roof space, cupboard or any concealed location.
For guidance please ring Zip Heaters on 0845 602 4533.
5 Position the Zip Varipoint to allow for future maintenance.
6 Do not install in a location where the unit or connecting pipe can freeze.
Plumbing
1 Check the incoming water supply pressure as this will determine the
layout and safety controls required. Remember that the mains water
pressure can increase considerably at night.
2 Refer to the diagrams 1 to 3 to determine accessories required and
layout.
3 Position the heater and controls to allow for future maintenance.
4 All control and safety valves are marked to show the direction of water
flow and will not function if incorrectly orientated. Do not break any seals
or attempt to adjust any safety valve; to do so may impair the safety of
the installation and will invalidate the guarantee.
5 To ensure a watertight seal use fibre washers for connecting services
between the heater and the connectors used. Complete the seal by
applying PTFE tape to the threads but do not over-apply. Do not use
plumbers paste to secure joints as this can impair the operation of any
valves connected to the heater.
6 Flush all pipework before making the final connections to the valves,
accessories and the heater.

Electrical
1 Switch off the main electricity supply before carrying out any work
involving a live circuit or access to components that may be live.
2 The Zip Varipoint is pre-wired with a length of 3-core cable suitable for
connection to a mains 240v supply. Connection must be made to a
double-pole isolating switch on a dedicated circuit or a double pole
switched spur.
3 f the cable length is insufficient it is recommended that the entire length
is replaced and no joins made to the original. To replace the cable:
a. Prise the temperature control knob off the spindle.
b. Release the one screw revealed by the knob.
c. Remove the cover by sliding forwards.
d. Pass the new cable through the entry point of the cover.
e. Remake the connections.
f. Ensure the cable is securely clamped.
g. Refasten the cover.
Do not switch on the electrical supply until the water heater is full
of water.
C mmissi ning
1 Check that all the requirements under “ nstallation Requirements” have
been met.
2 Check that all the water and electrical connections are correct and tight.
3 Open a hot water tap.
4 Open the isolating valve and permit the heater to fill.
5 When the water flows from the hot tap - turn off the hot tap.
6 Check for leaks, rectify as necessary.
7 Check the operation of the safety valve and the temperature and
pressure relief valve.
