Pipe Work
It is essential that the pipe work connecting to and from the heater has a
minimum bore (internal diameter) of 32 mm. To support correct air
purging and to ensure the heater remains completely full of water during
operation; the return pipe which carries the water back to the pool must
incorporate a safety loop or ‘kick-up’ in the pipe as close as possible to
the heater (see Fig.4)
NOTE: When coupling to a flexible pipe a safety loop can easily be
formed by directing the pipe up and over an obstacle. Pipe clips
should be used to securely fasten all hose connections.
Weather Protection
The heater must be installed within a dry weather proof area.
Caution! If the heater is unused during the winter months, it must be
drained to prevent frost damage.
Electrical Connection
The heater must be installed in accordance with the country / regional
requirements and regulations. In any event the work must be carried out
by a qualified electrician, who will provide a certificate of conformity upon
completion of the work. The power supply must be fitted with an RCD. If
required, your electrician may replace the cable entry gland supplied with
a larger size to secure the cable powering the heater. This will not affect
your warranty if undertaken by a qualified electrician.
Cable section: This should be calculated at 5-amp / mm² for distances
up to 20 metres (these sections are indicative and should be checked
and adapted if necessary for cable lengths over 20 metres).

Flow Requirements
The heater can accept the flow of water from either end, but only by
rotating the heater 180⁰. (See Fig. 6).
DO NOT REVERSE THE FLOW SWITCH.
Left to Right
Flow direction
Fig 6.
The flow rate of water into the heater must not exceed 17,000 litres per
hour (17m3 / hour / 3,740 UK gallons per hour). A higher flow rate will
require the installation of a bypass to prevent damage to the heater
elements. The heater will not operate unless the following minimum flow
rates are achieved:
1,000 litres / hour (1m3/hour / 220 UK gallons/hour) for 2 ~ 6-kW heaters
4,000 litres / hour (4m3/hour / 880 UK gallons/hour) for 9 ~ 24-kW heaters
Water Quality
The water quality MUST be within the following limits:
PH 6.8 - 8.0
TA (Total alkalinity) 80—140ppm (parts per million)
Chloride Content MAX: 150 mg/litre
Free Chlorine: 2.0 mg/litre
Total Bromine: Max 4.5 mg/litre
TDS (Total Dissolved Solids) / Calcium hardness 200— 1,000ppm
Stainless Steel heaters are NOT suitable for use on saline (salt) water pools.
ONLY heaters with titanium heating elements are suitable for use on saline
(salt) pools.

Operating Instructions
Upon completion of the installation, run the water-circulating pump to
purge the system and heater of air (i.e. remove any trapped air in the
system & heater). TIP: You can encourage air out of the heater ow tube by
gently elevating the exit port of the heater when the pump is running.
On initial power up of the heater the amber light should illuminate.
The heater will only switch ‘On’ (red light indicator illuminated) when
the following criteria are met:
•Water circulating pump is ‘On’ delivering more than the minimum
flow rate of water (see flow requirement information)
•The required water temperature point is set to a higher value
than that of the water
Selector knob operation:
To aid navigation through the controller options, the digital heater
is fitted with a selector knob for easy and user-friendly navigation.
To adjust or select any option simply turn the knob clockwise or
anticlockwise (see Fig.7).
To confirm selected option, press the knob button (OK). The display
should show message ‘SAVED’ confirming the changes (see Fig.8).
ENGLISH

Choose your language:
On initial power up, the display will illuminate and show a language
message (Fig.9). If the controller detects inactivity for 3 seconds, it
will default the language to English.
Fig 7. Fig 8.
Fig 9.

ENGLISH

There are five languages to choose from: -
- English
- French
- Spanish
- German
- Russian
To select a language, turn the knob clockwise or anticlockwise until
the desired language is displayed. Press the knob button (OK) to
accept the changes.
Note: To access language mode, press the knob button (during
heating only). You can also access language mode by resetting power
to the heater.
Set Point:
You can change setting (desired water temperature) any time by
simply turning the knob clockwise or anticlockwise until the
required temperature is shown on the display (Fig.10). To confirm
the changes, press the knob button (OK).
Fig 10.

The display should show ‘SAVED’ message.
ENGLISH

Heating mode:
If the heater is receiving enough flow and set point value is greater than
the pool water temperature ‘HEATER DELAY’ will be shown on the display
(Fig.11).
It will appear for two minutes before the device commences the heating
process. The delay time is required to prevent a cycling effect due to air
pockets trapped in the pipe work system or any water fluctuations.
The combination of the delay time and flow switch sensor is ensuring that
your device always receives enough flow and the heating element is fully
submerged. This will extend the life expectancy of the components and
the product.
After two minutes, the controller will switch on the heating output, RED
LIGHT will come ON and the display will show current water temperature
(Fig.12).
Fig 11.
The heater will stay on until set temperature point is reached. When
reached the heater will maintain pool temperature within 0.5°C differential.
Fig 12.

ENGLISH

Calibrate temperature:
Fig 13.
If for any reason the water temperature displayed by the controller is
different to the water temperature in your pool, you can simply adjust it
by pressing and holding the knob button for 5 seconds. The display will
show calibrate and actual temperature (Fig.13). Turn knob clockwise to
adjust it UP or anticlockwise to adjust it DOWN.
Note: The controller will allow maximum adjustments of ±2°C. If
controller displays ‘No flow’ message than entering to calibration
mode will not be possible.
Q: How long will it take to heat my pool?
A: Assuming no heat losses, and a heater sized in the ratio 1.5-kW
per 1,000 UK gallons of water (4,545-litres): it will take 2 days of
continuous running to raise the temperature of a pool from tap
temperature to swimming temperature. Heat loss will slow the heating
process, particularly during periods of cold weather, hence the higher
the water temperature is to be maintained above average ambient air
temperature, the slower the heating process will become.
The only inuencing factors are the level of insulation and the location
of the pool with regard to wind shelter.
Useful advice: To reduce running costs and increase the heating process;
Insulate the pool wherever possible. A floating solar cover is an essential
minimum to retain heat.

ENGLISH

Dedicated RCD Safety Circuit:
The heater is fitted with a high limit safety circuit which must be
connected a dedicated RCD and circuit breaker (see Fig.18).
The Safety Circuit is constantly monitoring flow tube temperature.
Air pockets, incrustation, debris build up or faulty components can
be a reason for a sudden rise of temperature inside the flow tube. To
protect heating elements and other components the Safety Circuit
will trigger RCD and shut down the power to the heater.
Fig 14.
Safety Circuit MUST BE TESTED FREQUENLY same as for the
RCD by pressing the Test Button on the Heater and RCD (see
Fig.14)
Note: The Safety Circuit is fitted with a TEST BUTTON which must be
tested after completing installation of the heater to confirm its
correct operation. When pressed RCD should instantly trip and cut
the power to the unit.

ENGLISH

Quick Function Test
Observe the main electricity meter when the heater is on (i.e.: red light
‘On’) and then observe it again when the heater is in the standby mode
(i.e. amber light ‘On’) The test should show that the meter is recording
more electricity being used by the heater when the red light is ‘On’. It
is impossible for an electric heater to waste energy, if it is drawing
power then that power will be turned into heat that will be transferred
to the water.
Accurate Function Test
If a more accurate test is required to confirm that your heater is delivering
the specified heat output, two electricity meter readings will need to be
taken from the properties main electricity meter, at one hourly intervals
(i.e. take one-meter reading and then a second reading exactly one hour
later) By subtracting the first reading from the second reading the number
of units (kilo watts kW) consumed can be calculated. Note that your
heater is also rated in kW hours.
The pool pump and heater will need to be running continuously during
the test (i.e.: with the heater red light ’On’) To avoid inaccurate results
when performing this test, it is important to refrain from using other high
current consuming appliances in the property (such as tumble dryer,
showers, cookers etc.). A large domestic pool pump of 1 horsepower will
draw less than 1kW in a one-hour period. The conclusion of the test
should prove that for example a 6kW heater and a ½ horsepower pump
will draw between 6.3- kW ~ 6.5- kW in one hour.

Trouble Shooting
HEATER WILL NOT SWITCH FROM STANDBY TO ON (RED LIGHT)
In most cases this will be the result of one of the following points not
being met.
Possible cause 1: The temperature point set has been achieved. To confirm
the increase of the temperature set, turn the dial to a value greater than the
current water temperature.
Fig 15.
Possible cause 2: NO FLOW message
This message is displayed (see Fig.15) only when the heater is not receiving
enough flow. This could be due to the circulation pump being switched off.
The pump is not powerful enough to meet flow requirements (page 8). The
cartridge filter needs cleaning or replacing. The sand/glass media filter
creates too high a backpressure and needs backwash.
Possible cause 3: HEATER DELAY message
Please refer to page 12
16
ENGLISH

Possible cause 4: OUT OF RANGE message
This error message will be shown (see Fig.16) in case of temperature
sensor failure or in case if the temperature inside flow tube is outside
of the measurement range of the sensor (0-100°C). During the
winter time temperature could drops below 0°C.
Possible cause 5: SHUTDOWN HIGH AMBIENT message (see fig.17) The
heater is fitted with intelligence sensors not only monitoring water
temperature but also the temperature within the electrical enclosure. To
protect your components if the temperature inside the enclosure reaches
60°C, the controller will shut down and go to STAND BY mode. This could
be due to the product being exposed to direct sun light, operating in very
hot environment. As soon as the temperature drops down the heater will
come back on to heating mode automatically.

NO DISPALY ON THE HEATER WHEN IT IS SWITCHED ’ON’
Possible cause: Power failure external to the heater
Remedy : Check any fuses, RCD or other switch components installed
in the supply cable.
Note: the heater PCB control board is tted with a fuse which should
be inspected.
THE FLOW TUBE DOES NOT FEEL WARM
Due to the high eciency of your electric heater no warmth should be
detectable from the ow tube of the heater.
The most likely causes of the ow tube feeling warm are:
Possible cause 1: The heater has been positioned in direct sunlight.
Possible cause 2: An air pocket is trapped inside the heater particularly if
the tank feels warmer at the highest point of the tank (as air rises)
THE WATER ENTERING MY POOL DOES NOT FEEL MUCH WARMER
The temperature gain of the water after it has passed through the heater
will be directly proportional to the volume of water being pumped in
relationship to the power output of the heater.
For example: A 6-kW heater, when connected to a 4,000 litre / hour
pump, will produce a lift in temperature of approximately 1.2 °C (almost
undetectable to the human hand) however, as the water being heated is
re-circulated from a single body of water, the time required to heat it
remains unaected by the volume of ow. A popular misconception is that
slowing down the ow rate will speed up the heating process.
