identify the terminals within. The mains supply terminal block is marked L, N and E and is top left (facing) on
the control unit Printed Circuit Board.
Note. Although the system can run from a 13 Amp switched socket outlet, this is not advised. In all instances
a separate RCD MUST be in circuit. The system draws approximately 4 amps at 240 volts A.C.
Whatever cable is run to the local switch arrangement, the MAXIMUM cable size to enter the control unit
should be 1.5mm

flexible TRS. Use a suitable joint box to convert if necessary. Permanently isolate, by fuse
removal, this supply until the total installation is complete.
Do not apply power until then
.
The next stage is the locating and fitting of the display unit.
13)
Refer to the Guide Sheet DIAGRAM C
. The
display unit
is an important part of your system. Choose the
location carefully. The unit is designed to be mounted “flush” using a plaster-depth back box, or “surface”
using a surface back box. The display unit should be located in a visible position, in an area that is often
occupied. The display unit is wired back to the control panel, using standard “Alarm” cable. This cable should
be four cores at 1 amp per core rating (7/0.2 mm each core. Core colours red, yellow, black, blue). The cable
should be connected between the terminal block on the back of the display unit to the terminal block marked
“DISPLAY” in the control panel. The terminal blocks at both ends are marked R for RED core, Y for YELLOW
core, Bu for BLUE core and Bk for black core. The terminal block is marked display and is top right (facing)
on the control panel Printed Circuit Board.
(
Note. If you wish to use the PUMP LOCK-OUT MODE or BMS contact on the display unit and you need to
bring the feed from the contact back into the same location as the CONTROL unit, use 6 core cable. The two
remaining cores go into the pair of terminals at the back of the display unit. See the document on NON-
STANDARD SYSTEMS for details of the BMS CONNECTIONS and PUMP LOCK-OUT mode). The next
stage is the wiring in (and installation) of the pump.

Refer to the Guide Sheet DIAGRAM C

At this stage, the pump should not be in the tank.
To install the pump you should take great care. It is a
HEAVY item. Be safe. Two persons will make the job much easier. Take the pump to the tank turret. Release
the ties on the mains electrical cable. Uncoil the Hose. Draw the mains electrical cable through the duct
along with another draw-wire (or rope) to pull through the sensor cable later. When the pump cable is fully in
