INTRODUCTION

Thank you for purchasing a Cygnet Evolution 2 aquatic electric heater manufactured to the highest

standards in England.

To ensure years of trouble-free service, please read and follow these instructions for proper installation,

maintenance and use.

WARNING: Failure to install the unit correctly may result in the warranty being void.

Please retain this manual for future reference.

1. PRODUCT OVERVIEW

Fig.1

Dimensions:

* for dimension ‘L’ – refer to section 2.5

2.GENERAL INSTALLATION INSTRUCTION

2.1 Mounting instruction

The heater should be either installed horizontally or vertically allowing enough space for the pipe

connections and wiring. It should be firmly secured using screws to a firm base or wall.

WARNINGS: If the heater is placed against a combustible material a fireproof barrier must be

placed between the unit and the wall, this must cover a minimum of 15cm

around the outside of the heater. The unit mustnot be covered to allow adequate

ventilation.

The heater must be installed within a dry, permanent weather-proof area. In any

case where water or moisture enters the enclosure the warranty will be void.

Caution: If the heater is unused during the winter months, it must be drained to prevent frost

damage. Water must not be allowed to freeze in the heater, as this will cause severe

damage.

See Fig. 2 for mounting instructions when securing to the wall or floor.

2.2 Pipe work

The heater should be installed at a low point in the filtration system. It should be positioned downstream

of (after) the filter and upstream of (before) any dosing or other water treatment plan (see Fig 3).

Fig.3

Fig.4

2.3 Flow direction

The heater can accept flow of water from only one end (see Fig. 5). If the flow direction is opposite to

Fig. 5 the heater must be rotated by 180° so the flow switch is always where the water exits.

DO NOT REVERSE THE FLOW SWITCH

INLET OUTLET

Fig. 5

It is essential that the pipe work connecting to and from the heater has a minimum bore (internal diameter)

of 32mm. 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.

Fig. 6 Fig. 7

If rigid pipework is used

There is no need to use mastic or PTFE tape to connect unions or hosetails to the heater, use the O-ring

supplied which should be slid over the threaded ends (see Fig. 6).

All factory unions are made from ABS plastic, when gluing connections to an ABS pipe an ABS cement

must be used or when using a PVC pipe, a Transition cement must be used (see Fig. 7).

NOTE: Be sure to apply the glue evenly and to all surfaces that will be in contact to reduce the

risk of leakage.

If flexible pipework is used

Connect the pipe to the non-threaded side of the hosetail and secure using two jubilee clips

(See Fig. 7)

NOTE:

•The hosetail may need to be cut depending on the diameter of the pipe.

•Wrap PTFE tape or use silicone around the hosetail before connecting the

pipe to reduce the risk of leakage.

•When using non-standard pipework, the first thing to note is that the smooth

end of the pipe will not fit into anything other than another fitting of the same

brand. You will have to cut it off. The hose tail will push fit in to the cut end

of the pipe, but it will not be watertight. You can put two jubilee clips on it

but because of the ridges in the pipe it will not squeeze down tight. It will

need to be sealed with a bathroom type mastic sealant.

2.4 Electrical connection

WARNINGS:

•This device must be installed by a qualified Electrician following the

instructions provided in this manual. The manufacturer will not be liable for

any issues caused by poor or improper installation.

•Any alterations made to the unit (unless stated) will affect the warranty. This

also applies if components are changed for non-standard components

acquired anywhere other than direct from the manufacturer.

•Incorrect installation may result in serious damage to property/persons.

•The heater must be installed in accordance with the country/regional

requirements and regulations and an Electrical Installation Certificate must

be provided on completion of the installation.

•The power supply must be fitted with a 30mA RCD. If required, the

Electrician may replace the cable entry gland supplied with a larger size to

secure the cable powering the heater.

Minimum cable sectional area

This should be calculated at 5-amp/mm2for distances up to 20 metres (these sections are indicative and

should be checked and adapted if necessary, for cable lengths over 20 metres).

Fig.8

Connections

•To connect the power supply cable, remove access cover (see Fig. 8).

•Make sure that all connections to the terminal block are correct as per the label inside the heater

and they are tight.

•Make sure not to expose the cable to anything which can cause damage to it i.e. sharp edges, hot

surfaces, or crush hazards.

•The cable should be fixed to avoid any trip hazard.

2.6 Dedicated RCD Safety Circuit

•The heater is fitted with a high limit Safety Circuit which must be connected to a dedicated RCD

and circuit breaker.

•The Safety Circuit is constantly monitoring the flow tube temperature. Air pockets, incrustation,

debris build-up or faulty components can be a reason of a sudden temperature rise inside the flow

tube. To protect heating elements and other components the Safety Circuit will trigger the RCD

and shut down the power to the heater.

WARNING: The Safety Circuit must be connected. Failure to do so will void the warranty and

might result in product failure.

NOTE: The Safety Circuit is fitted with a TEST BUTTON which must be tested after

completing installation of the heater to confirm it is operating correctly. When

pressed, the RCD should instantly trip and cut the power to the unit (See Fig. 9).

Fig.9

3. OPERATING INSTRUCTIONS

3.1 Flow requirements

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.

NOTE: The heater will not operate unless the following minimum flow rates are achieved:

1,000 litres/hour (1m3/hour/220 UK gallons/hour)

3.2 Water quality

The water quality MUST be within the following limits:

•PH: 6.8 –8.0

•Total Alkalinity (TA): 80 –140 ppm (parts per million)

•Chloride Content MAX: 150 mg/litre

•Free Chlorine: 2.0 mg/litre

•Total Bromine: Max 4.5 mg/litre

•Total Dissolved Solids (TDS)/Calcium hardness: 200 –1,000 ppm

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) water pools.

WARNING: Failure to meet the water quality limits will void the warranty.

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 and heater).

•Switch on the power supply to the heater. This will be indicated by the illuminated Amber light on

the panel.

•Turn the thermostat to the desired temperature.

•The heater will only start heating (red light indicator illuminated) when thefollowing criteria are met:

➢Water circulating pump is ‘On’ delivering more than the minimum flow rate of water (see 3.1

flow requirement).

➢The required water temperature point is set to a higher value than that of the water.

Useful advice:

To reduce running costs and speed up the heating process, insulate the pool wherever possible. A floating

solar cover is an essential minimum to retain heat.

3.3 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 anti-clockwise (see Fig. 10).

To confirm selected option, press the knob button (OK). The display should show message ‘SAVED’

confirm the changes (see Fig. 11).

Fig. 10

Fig. 11

3.4 Choose your language

On initial power up, the display will illuminate and show a language message, (see Fig. 12). If the controller

detects inactivity for 3 seconds, it will default the language to English.

Fig. 12

There are five languages to choose from English, French, Spanish, German and Russian.

To select a language, turn the knob clockwise or anti clockwise 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
