Electrical Connection - Elecro Engineering Cygnet Aquatic Heater Manual De Instalación Y Funcionamiento

Positioning (continued)
Your heater should be horizontally or vertically sited allowing sufficient
space for pipe connections and wiring, it should be screw fixed securely to
a firm base or wall.
The heater should be installed at a low point in the filtration system.
It must be positioned downstream of (after) the filter and upstream of
(before) any dosing or other water treatment plant. (see Fig.2)
Pipe Work
It is essential that the pipe work connecting to and from the heater
has a minimum bore (internal diameter) of 1¼" (32mm).
To assist 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 pond must incorporate a safety loop or 'kick-up' in the pipe as close
as possible to the heater (see fig 3).
NOTE: When coupling to a flexible pipe a safety loop can simply be
created by routing the pipe up and over an obstacle. Remember to
use pipe clips to securely fasten all hose
Weather Protection
The heater must be installed within a dry weather proof enclosure.
CAUTION! If the heater is not used during winter months it must be drained to
prevent frost damage.

Electrical Connection

The heater has been supplied pre-wired with a power lead. Sizes 1-kW
to 3-kW also have a plug; 4-kW models must be installed by a qualified
electrician.
