Electrical Supply

The product MUST be earthed.

All system components shall be of an approved type and all

wiring to current I.E.E. wiring regulations.

External wiring must be correctly earthed, polarised and in

accordance with the relevant standards.

In GB, this is BS 7671.

In IE, this is the current edition of ETCI rules.

The product MUST be connected to a permanent 230V ac,

50Hz supply.

Connection of the whole electrical system of the product,

including any heating controls, to the electrical supply MUST

be through one common isolator and must be fused 3 Amp

maximum.

Isolation should be by a double pole switched fused spur box,

with a minimum gap of 3mm for both poles. The fused spur

box should be readily accessible and preferably adjacent to

the product. It should be identified as to its use.

Alternatively connection can be made through an unswitched

shuttered socket and 3A fused 3-pin plug both to the current

issue of BS 1363, provided they are not used in a room

containing a bath or shower.

Wiring to the product must be PVC 85°C insulated cable, not

less than 0.75mm2 (24/0.20mm).

IMPORTANT: Risk of fatal electric shock from touching live

connections.

Before working on the system wiring, including the Fluropro,

isolate the power supply.

The circuit board can be damaged if short circuited through

the connection leads. For safety purposes, a max. of 30 mm

of insulation may be removed from the ends of 230 V leads

which will be connected to Fluropro wiring connectors. If more

insulation is removed, there is a risk of short circuiting the

circuit board.

When exchanging the solar controller in an existing

system, sensor-curve characteristics should be taken

into consideration and the sensors should be replaced if

necessary!

The immersion heater must be installed with an additional

relay or contactor with a circuit-breaking capacity of at least

16 A. Never operate an immersion heater in connection with

the Fluropro without an additional external relay or contactor.
