In this manual a warning symbol is used to call attention
to potentially hazardous situations:
WARNING!
Information about potential personal injury and/or
damage to the equipment.
Safety warning labels (see Figure 1.1) are afxed to
the Drumlter lids to warn personnel to keep hands and
ngers away from moving parts of the lter.
This equipment is CE marked ensuring that the
equipment is designed, manufactured and
described in conformity with the Machine
Directive of EU 98/37/EU (AFS 1994:48).
The CE marking does not cover components not approved by Hydrotech AB,

Operation and maintenance manual for
Hydrotech Drumlter HDF501-series
The lter is equipped with a safety switch (see Figure 1.7). In an emergency
shutdown situation, set the safety switch to OFF (0).
In the event of a power failure, set the safety switch to OFF to prevent the lter
to accidentally start rotating when power returns.
Electrical connection must be performed by an authorized electrician and in
accordance with local regulations. See also Appendix D.
The lter tank or frame must be connected to earth. See also section 4.4
A lockable safety switch must be installed if the control box is mounted far
away from the lter (further away than 7 m within EU countries).
The lter is activated by setting the safety switch to ON (1) and then selecting
HAND or AUTO on the selector switch on the panel front. Setting the selector
switch to 0 stops the lter.
WARNING!
Set the safety switch
to OFF (0) and lock it
in the OFF position by
means of a padlock
before starting any
work on the lter.
WARNING!
Access to the lter by
unauthorised persons
must be strictly
prohibited. An outdoor
installation should be
fenced off.
WARNING!
The lter can suddenly
start rotating if
automatic control is activated. Do not touch any moving parts. Do not
climb up on the lter construction when the lter is activated.
Protection guards are tted around the power transmission and in front of the
support wheels. Make sure these are correctly and rmly tted at all time.
WARNING!
The vapours from the backwash water may contain harmful substances.
If the lter is equipped with a chemical dosage system, the vapours from
the chemical dosage system contain substances that are harmful. Use
suitable personal protection according to local regulations.
Measured noise level from the lter is less than 74 dB (A). If necessary, use
suitable personal protection according to local regulations.

When received, the equipment should be thoroughly inspected for any
damage that may have occurred during transport.
The delivery note, manual and the spare part set are attached to the
equipment.
Check all parts against the packing list. For safe transport it is necessary that
some parts are not assembled when delivered. Handle fragile parts with care.
Should it be necessary to store the equipment for a longer period (several
days or more) certain precautions should be taken in order to prevent
unnecessary damage to the equipment:
Preferably, the equipment should be stored inside, in a room with
temperature above freezing.
For outdoor storage it is necessary to protect the lter from direct sunlight
as the heat and UV radiation may damage the lter panels.
Filters are delivered covered by plastic, within the wooden crate. If placed
outdoors, a special type of corrosion may develop, especially in coastal
areas. Humidity on the inside of the plastic forms the anode, and dry
exposed parts the cathode. Filters must therefore be unpacked after
delivery in these areas.
When lifting the unopened crate a fork lift with fork extensions should be
used.
Unpacked lters with tank (type 1) may be lifted by a fork lift.
Do not use a crane or overhead gantry, and straps!
WARNING!
Before unloading, the working area should be fenced off according to
local regulations to prohibit access by unauthorised persons.

The following requirements must be met before installation can begin
The electrical specications of the equipment corresponds to the available
line current specications
The equipment is undamaged (no damages from transport or storage)
For outdoor installations it is necessary to protect the lter panels from direct
sunlight as the heat and UV radiation may otherwise destroy the lter panels.
Protect the lter from freezing. At water temperatures above +5 °C and air
temperatures warmer than -10 °C, the lids of the lter is enough for protection.
At lower water and air temperatures, the lter should be installed indoors.
The lter should be tted on an even
surface with appropriate torsional and
structural strength.
The lter must be properly levelled in
both directions (see gure 4.1).
600 mm wide walkways should be
tted around the lter in order to
provide easy access to the lter for
service work.
In some applications an external by-
pass must be arranged in case of e.g.
a power failure to avoid a too high
differential pressure across the lter
cloth.
Electrical connection must be performed according to local regulations. Check
the settings of the motor protectors against amperage readings on the motors
(see Appendix A & D).
The Hydrotech Drumlter and its associated equipment should be protected
using a suitable Equipotential Earth Bonding system. This is very important to
avoid galvanic corrosion. Typically use a cable with an area of 10-16 mm2. The
cable should be attached to the same electrical potential as the drive system.
WARNING!
All electrical works should be installed by a qualied and competent
electrically trained person.
