Basement Water Drainage Solutions: Delta Back Up Battery
Water Management Solutions for flooded areas : Delta Power Pack
|
If
you’ve installed a cavity drain system internally,
one of the main design considerations is how are you going
to manage the water collection and discharge. This can
be done passively into existing drainage points, if available
and appropriate. However, the majority of projects require
a collection sump + pump, to automatically manage the
evacuation of any water ingress. This type of unit requires
mains power to operate, so what can
be done if the power fails, and is coincident with high
water ingress?
Here’s a water drainage solution option from Delta:
Delta Battery Power-Pack
This unit is designed to run one 302SE/HP pump if a power
failure occurs. The unit is trickle charged under normal
conditions, and will auto switch to battery power if mains
power fails. The unit will pump approx. 8,910 litres in
back up mode but this can be upgraded by adding up to
ten extra power units. Adding one unit raises the back
up capacity to approx. 26,730 litres.
The Delta Water Drainage Solution, Battery Power-Pack unit has
been specially converted to run one DELTA 302 SE/HP pump.
The unit has an integral audible alarm. The Battery system
is designed to be located outside the sump in a convenient
and dry location.
The battery system is supplied with a two-metre three-core
cable. One end has a female plug, which
fits into the corresponding male fitting in the rear of
the battery unit, and the other end is bare.
The bare end should be hard wired into a non-switched
fused spur.
We recommend that you employ a qualified electrician
to undertake this work, which is usually fairly simple
and inexpensive.
The unit is also supplied with a three pin male plug,
which should be wired on to one DELTA 302 SE/HP pump cable.
The wiring should be made as follows:
|
The male three-pin plug should be plugged into any one of
eight female sockets in the rear of the unit. The other seven
sockets should not be used in this application.
To add extra power packs remove the guard on the main pack
by removing two screws. Then simply plug the extra battery
pack into the main pack. The main pack will accept up to ten
batteries. The batteries are linked into each other in sequence.
The battery should be switched on by pressing the button marked
one. The battery will run a test when fi rst started and will
self-test weekly.
If the electricity supply fails, the battery unit will run
the DELTA 302 SE/HP pump at the normal capacity with no loss
of performance. When the main power resumes the battery will
recharge. Recharging time is approximately three hours. The
anticipated life of the unit is one hour of continuous use
(<8,910 litres) or 47 one-minute cycles (<6,500 litres).
With one extra battery pack the anticipated life is three
hours continuous use (<26,730 litres) or 150 one minute
cycles (<22,680 litres). These
figures are based on a <3 metre head of water. Figures
will vary depending on the head height
and distance to be pumped from the sump. The expected life
of the battery pack within the system is between three and
six years. The internal battery should be changed when the
crossed battery indicator light illuminates or as required
by any maintenance contract that may exist.
Health & Safety: When installing machinery
in industrial or educational environments it is important
to install in
compliance with Health & Safety at Work Act 1974. All
electrical installations must comply with BS.7671:2001 (2004),
the
16th edition of IEE Regulations, or any subsequent editions.
Electrical products are intended for permanent hard-wired
connection to the power supply, with safety devices, connection
and switching, appropriate to the particular application.
