place, with the waterproof connector accessible (on enough spare cable to reach ground level easily), the
pump can be lowered carefully, on its rope, into the tank
. Do not lower the pump by the electrical cable or
by the hose.
One person should hold on to the pump hose free end and should guide the other person, not
allowing the cable to be trapped by the lowering pump. Once the pump is sitting on the tank bottom, the rope
should be tied off to the turret bracket, just sufficiently taught to keep the pump upright but not enough to
suspend it. The pump hose should now be connected to the protruding thread of the tank connector. Do not
over tighten.
Run the pump electrical cable from the duct to the control panel and wire it in to the terminals marked L,N
and E, designated pump. The terminals are just below the MAINS IN terminals upper left on the PCB
(facing).
NOTE. If you have extended the pump cables and have used oversized, armoured or solid conductors to
achieve this you must convert to the previously specified cable size using a joint box before entering the
control panel. A suitable pump isolator switch is often used as a convenient joint box.
You are now ready to install and connect the
depth sensor
(often referred to as just
sensor
)
15)
Refer to the Guide Sheet DIAGRAM C
.
The
depth sensor
is a robust item but must not be subjected to excessive impact, crushing or stretching of
the attached cable. To avoid these occurrences it is the last item to be installed.
NOTES.
a) The Sensor cable is of a pre-ordered length, which you have checked upon receipt.
b) It is NOT advisable to extend this cable by jointing. If it is absolutely necessary you must ensure that any
joint is watertight and accessible.
c) There must be NO jointing of this cable in the tank turret.
d) Any use of cable not supplied by Envireau for the express purpose MUST be of a SIMILAR specification.
The minimum specification is 4 core (16/0.2mm per core, RED, YELLOW, GREEN, BLUE or NUMBERED)
screened by braid or SWA. The outer insulation MUST be rated at 240v RMS.
e) The screen or SWA must be EARTHED at the control unit end only and must be electrically continuous
with the screen on the sensor cable supplied.
