1. Safety instructions
Please read these instructions carefully before installing or using the appliance!
Keep the instructions handy with the appliance for future use!
Installation, initial operation and maintenance of this appliance must only be con-
ducted by an authorised professional, who will then be responsible for adherence to
applicable standards and installation regulations. We assume no liability for any dam-
ages caused by failure to observe these instructions.
To observe additionally for pressureless installation:
• The water outlet behind the devices must not be blocked, and the water flow must not be restricted.
• The water outlet facilities, such as shower head, jet control and other outlet unit, must be decalcified regu-
larly. Deposits must be removed in regular intervals.
• Only the fittings recommended by the manufacturer may be used.
• If the appliance is exclusively connected to a single shower, only the shower heads recommended by the
manufacturer may be used. No other fittings or appliances which decrease the water flow to the shower
may be installed.
• Do not use the appliance until it has been correctly installed and unless it is in perfect working order.
• Do not remove the front cover under any circumstances before switching off the mains electrical supply to the
unit.
• Never make technical modifications, either to the appliance itself or the electrical leads and water pipes.
• The appliance must be earthed at all times.
• Pay attention to the fact that water temperatures in excess of approx. 43°C are perceived as hot, especially
by children, and may cause a feeling of burning. Please note that the fittings and taps may be very hot when
the appliance has been in use for some time.
• The appliance is only suitable for domestic use and similar applications inside closed rooms, and must only
be used to heat incoming water from the mains supply.
• The appliance must never be exposed to frost.
• The values stated on the rating plate must be observed.
• In case of malfunction, disconnect the fuses immediately. In case of leaks, cut off the mains water supply
instantly. Repairs must only be carried out by the customer service department or an authorised professional.
• This appliance can be used by children aged 3years and above and persons with reduced physical, sensory
or mental capabilities or lack of experience and knowledge if they have been given supervision or instruction
concerning use of the appliance in a safe way and understand the hazards involved. Children shall not play
with the appliance. Cleaning and user maintenance shall not be performed by children without supervision.
• If the appliance is factory equipped with a power supply cable, it must be replaced with an original spare
cable from the manufacturer in case of damage by an authorised technician in order to avoid any hazards.
• For appliances with direct connection, an all-pole disconnecting device with a contact opening width of
≥ 3 mm per phase must be provided at the installation end, according to Australian wiring rules AS/NZ3000.
• The wall bracket must be secured with the supplied screws and dowels. The appliance must be secured to
the wall bracket. The appliance may only be operated if it has been properly mounted on the wall bracket.
• The prescribed nominal pressure stated on the rating plate may not be exceeded at any time.
• The required water resistance may not fall below the value stated on the rating plate at any time.

Installation site
• Appliance must only be installed in frost-free rooms. Never expose appliance to
frost.
• The Appliance must be wall mounted and has to be installed with water connectors
downward.
• The appliance complies with protection type IP25.
• To avoid thermal losses and dead legs, the distance between the instantane-
ous water heater and the furthest outlet should be kept as short as possible
(<6meters). In addition all hot water pipe work should be insulated in accordance
with AS/NZS 3500.
• For maintenance work, a shut-off valve should be installed in the supplyline. The
appliance must be accessible for maintenance work.
• The specific resistance of the water must be at least 1100Ωcm at 15 °C. The specific
resistance can be asked for with your water distribution company.
• For 50°C models: The appliance delivers water not exceeding 50 °C in accordance
with AS3498.
• For 60°C models: The appliance may be able to be used with a thermostatic mixing
valve or where serving a fixture that does not require temperature limitation such as
a commercial kitchen sink or cleaners sink. Refer to AS/NZS 3500.4.
6. Installation
The following regulations must be observed:
• Installation must comply with all statutory regulations, as well as those of the
local electricity and water supply companies.
• The rating plate and technical specifications
• Only intact and appropriate tools must be used
• Installation must comply with all statutory regulations, AS/NZS 3000, AS/NZS
3500, as well as those of the local electricity and water supply companies
• These instructions must be read and fully understood before commencing the
installation. If in doubt, or in need of further guidance please ring Zip
on 1800 638 633

6. Installation
Note: If you install this instantaneous water heater in exchange for a conventional
instantaneous water heater, there is generally no need to drill holes for the wall brack-
et, in this case step 2 would not be necessary.
Thoroughly rinse the water supply pipes before installation to remove soiling
from the pipes.
1. Using a 12 mm hexagon socket screw key, screw the screw-in nipples into the wall
connections. The seals must be fully screwed into the thread. After tightening, the
double nipples must protrude by at least 12mm.
2. Hold the included mounting template on the wall and align it so that the holes in
the template fit over the connections. Mark the drill holes according to the template
and drill them using a 6 mm drill. Insert the included dowels.
3. Screw in the wall bracket. Offset tiling or uneven surfaces can be compensated by
up to 30 mm with the aid of the spacers supplied. The spacers are fitted between
the wall and the wall bracket.
Installing the wall bracket
Note: Fasten the screw nuts with caution, to avoid damage to the valves or the
piping system.
1. As shown in the illustration, screw the cold water connection piece with the union
nut and the ½inch seal onto the cold water connection.
2. Screw the hot water connection piece with the union nut and the ½inch seal onto
the hot water connection.

1. To open the appliance hood, take off the faceplate and unscrew the main hood
screw.
• When replacing an appliance, the electrical power supply cable may be connected
in the upper part. Only in such case, follow the instructions “Electrical connection
from above”.
2. Place the appliance on the heater bracket so that the threaded rod of the wall
bracket fits in the provided hole of the appliance. If necessary, slight corrections are
possible by carefully bending the threaded rod of the wall bracket. However, it must
be possible to screw on the water connection pipes of the appliance without apply-
ing force.
3. Screw the two ⅜inch union nuts of the appliance‘s water connection pipes, each
with the ⅜inch seal, onto the fittings.
4. Screw the plastic knurled nut onto the threaded rod of the wall bracket.
5. Open the water supply line to the unit and slowly open (position “open“) the shut-
off valve (a) in the cold water connection piece. Check all connections for leaks.
6. Next, open and close the hot water tap valve several times until no more air
emerges from the line and all air has been eliminated from the instantaneous water
heater.

Note: Fasten the screw nuts with caution, to avoid damage to the valves or the
piping system.
For direct connection, the two ½inch screw-in nipples and the ½inch seals must be
screwed into the ½inch union nuts of the hot-water and cold-water connectors. The
two ½inch caps of the side outlets of the hot-water and cold-water connectors must
be removed and screwed onto the open end of the screw-in nipples. The hot-water and
cold-water connectors must then be screwed into the 3/8inch union nut of the appli-
ance and delivery pipe, together with the 3/8inch seals.
For direct connection, it is advisable to mount the appliance at a distance as illustrated
alongside, using the spacer sleeves supplied. It should therefore be noted that the two
fixing holes near the lower pipe connections are also used.
The flared end of the pipes must be screwed into the ½inch side outlets of the hot-
water and cold-water connectors with ½inch union nuts and ½inch seals. The holes
required for the pipes must then be broken out of the housing with the aid of a blunt
implement.
In case of direct connection please note: Put the strainer into the cold water con-
nection!
