These instructions apply to the submersible pumps and aerators specified on the
cover. They are intended for use with periodic maintenance, under conditions
approved by a competent installation technician, in water of up to 40°C, with
sewage or nonflammable liquids compatible with cast iron, nitrile rubber and the
other materials, without the mixture exceeding a viscosity of 10 cp (m pa•s) nor a
density of 1,1. During use, discharge conduit and cabling should be touched only
if need be, and the water absolutely not. The area should be accessible to
competent maintenance technicians only, to the absolute exclusion of children
and the general public.
The pumps conform to the relevant directives of the EU.
CAUTION!
The pump must not be permanently installed in swimming
pools or fountains if the installation area can be flooded.
DANGER!
The pump must not be used in an explosive or flammable
environment or for pumping/aerating flammable liquids.
CAUTION!
The pump must not be run if it has been partially dismantled

Handling and Storage
The pump can be transported and stored either vertically or horizontally. Make sure that it is securely lashed and cannot roll.
CAUTION!
The pump must always rest on a firm surface so that it will not
overturn. This applies to all handling, transport, testing and
installation.
CAUTION!
Always lift the pump by the lifting handle - never by the motor
cable or hose.
The time between delivery and the first hour of pumping is
extremely hazardous. Care need be taken not to crush, kink or pull the
fragile cable and not to break the hard but brittle cast iron or endanger a
bystander. No water should enter the open end of the cable during handling.
Store in a dry place to avoid corrosion by damp air inside the pump.The pump
should first be rinsed if a corrosive mixture has been pumped. Rinsing with water
mixed with cutting oil can be of some help if no dry storage is available.
Installation
Safety measures
In order to reduce the risk of accidents during service and installation work, take
extreme care and bear in mind the risk of electrical accidents.
Only a competent electrician should be allowed to work on the electrical circuit,
since only he knows the dangers involved and the regulations.
Do not connect the power supply if any part of the pump or its installation has not
been completed and inspected, or if anyone is touching the water.
CAUTION!
The lifting tackle must always be designed to suit the pump
weight. See under the heading “Product description”.
Installation of pump with guide-rail specification
(duckfoot bend):
This is intended to allow the pump to be raised for inspection,
without unbolting the discharge pipe, along a pair of galvanized
or stainless steel “gas” tubes that need to be purchased from a
local merchant. It consists of a 90° bend with pedestal for bolting
down and a holder for the tops of the tubes. The tubes need to be
parallel and vertical, and the lifting tackle above the center of
gravity of the pump. As the pump is lowered, the pump´s flange
closes by weight. This applies TOS-BER aerators, too.

Installation of pump with normal bend:
Usually, with this bend, a quick coupling or at least a flange is
arranged in the conduit for quick disconnection at an accessible
level, to enable the pump to be lifted out for inspection. The
pump needs rest vertically on an ample and perfectly stable
surface, or to be suspended by its handle or lifting eye(s). All this
applies to BER and TR(N) aerators, too.
The pumps and aerators, should not be used in an atmosphere that could
become explosive nor in water that might contain traces of flammable liquid.
Thank you for having selected a Tsurumi submersible pump. For full benefit of this equipment, you should read, before use, the following points
which are necessary for safety and reliability. The table of contents guides you to the respective warnings and instructions.
Chain:
The end of the lifting chain need to be safely hooked where it can be reached if
the pump fails to work.
