Installing the wall bracket (Fig 1)
1. Thoroughly flush the water supply pipes before installation to remove any
water borne debris.
2. If required, using a 12mm hexagon key, screw the screw in nipples into
the wall connections. After tightening the double nipples must protrude by
12mm.
3. Hold the mounting template on the wall and align it so that the holes in the
template fit over the connections. Use the template to locate the drilling
positions and drill them with a 6mm bit, ensuring that there are no hidden
cables or pipe-work. Attach the wall bracket using the fixings and screws
supplied.
4. Offset tiling or uneven surfaces can be compensated for by up to 30mm
with the aid of the spacers supplied. The spacers are fitted between the
wall and the wall bracket.

Installing the applicance
1. Remove the appliance cover by first removing the fascia panel
then unscrewing the fixing screw.
2. If the power supply cable is to be connected in the upper part
of the appliance follow instructions for “Electrical Connection
From Above” on page 13.
3. Place the appliance on the wall bracket with the threaded
stud through the fixing hole in the back plate. If necessary the
threaded stud can be carefully bent through a maximum of
approximately 30° to allow it to align with the fixing hole (see
Fig 4). However, it must be ensured that the water connection
pipes can be connected to the appliance without applying
force.
4. Screw the two 1/2” union nuts on the appliance’s water connection pipes, each fitted with a 1/2” seal, onto the fittings.
5. Screw the plastic knurled retaining nut onto the threaded stud
of the wall bracket.
Fig 3
6. Open the water supply to the appliance and slowly open the
shut-off valve (see Fig 5) in the cold water connection piece to
position I. Check all connections for leaks.
7. Ensure that all air is eliminated from the water heater by opening and closing the hot water tap until no more air emerges.

7. Installation
Surface mounted installation
1. If required for surface mounting, the two ½”screw-in nipples
and the ½” seals must be screwed into the ½” union nuts of
the hot water and cold water connectors. The two ½” caps
of the side outlets of the hot water and cold water connectors must be removed and screwed into the open end of the
screw-in nipples. The hot water and cold water connectors
must then be screwed into the 1/2” union nut of the appliance and delivery pipe, together with the 1/2” seals.
2. When surface mounting, it is advisable to install the appliance at a distance from the wall as illustrated in Fig 6 using
the spacer sleeves supplied. In this case the two fi xing holes
near the lower pipe connections should also be used.
3. The fl ared end of the pipes must be screwed into the ½”
side outlets of the hot water and cold water connectors
with ½” union nuts and ½” seals. The holes required for the
pipes must then be broken out of the housing using a blunt
implement.

the electrical leads. The protection sleeve must be used and free
from damage.
3. Open the control panel (B) to the right.
4. Fit the connecting cables into the terminal block (C) according to
the wiring diagrams on page 11. Ensure all connections are fully
tightened and secure.
5. The appliance must be earthed.
6. Pull the protection sleeve over the connecting cables until it fi ts in

8. Commissioning
Before switching on the power supply, ensure the appliance is completely fi lled
with water by carefully opening and closing the hot water tap until all air has
been eliminated from the water heater and no more air emerges.
Every time the appliance is drained (e.g. after work on the plumbing system or
following repairs to the appliance), the heater must be re-vented in this way
before reconnecting the power supply.
The maximum power rating of the appliance can be selected from 18, 21, 24
or 27kW at the time of installation. The maximum power rating should only be
selected with reference to the technical data on page 5, after ensuring that
correct cable sizing and fuse protection is in place and with regard to local site
conditions and AS/NZS 3000 electrical regulations.
This must only be done by a qualifi ed tradesperson.
1. Switch on the power supply to the appliance. The digital display will light
up.
2. When switching on power for the fi rst time, “21” will fl ash on the display. If
not, please refer to the section “Reinstallation”.
3. Select the required maximum power rating using the up and down
arrow keys (18, 21, 24 or 27 kW).
4. Press
operate.
5. Mark the set power rating on the product rating plate.
6. After selecting the maximum power rating, the heating element will acti-
vate after approximately 30 seconds of continuous water fl ow.

11. Maintenance
N.B. Maintenance work must only be carried out by a qualifi ed tradesperson familiar with instantaneous water heaters.
Plastic surfaces and sanitary fi ttings should only be wiped with a damp cloth.
Never use abrasive or chloric cleaning agents or solvents.
Outlet fi ttings (tap nozzles and shower heads) should be unscrewed and cleaned at regular intervals.
The electrical and plumbing components should be inspected regularly by a competent person to ensure proper functioning
and operational safety. Water quality should be considered when determining the frequency of inspection.
Cleaning and replacing the fi lter strainer
The cold water connection of the appliance is fi tted with an integral
shut-off valve and fi lter strainer (See Fig 12). Soiling of the strainer
may reduce hot water output from the unit.
The strainer should be cleaned or replaced as follows:
1. Isolate the electrical supply to the unit.
2. Remove the appliance cover and close the shut-off valve (see
Fig 13) in the cold water connection piece to position II.
3. Unscrew the screw plug (A) from the cold water connection
piece and take out the strainer (B) (see Fig 14).
4. The strainer can now be cleaned or replaced.
5. After re-fi tting the strainer tighten the screw plug.
6. Slowly open the shut-off valve in the cold water connection
piece to position 1.
7. Vent the unit by carefully opening and closing the hot water tap
several times until all air has been eliminated from the water
heater and no more air emerges.
8. Re-fi t the appliance cover and restore power to the unit.
