It is also possible to check the direction of rotation with a
"motor and phase rotation indicators". This device is sup-
ported on the outside of the motor housing of the activat-
ed pump and indicates the direction of rotation by a LED.
Automatic float switch (Model ... A)
Version with HOMA-Nivomatik automatic float switch, AS
float, 10m connection cable, control unit and manual and
auto switch. The 1Ph pumps are equipped with built-in
capacitors and connectors. The three-phase pumps have
a CEE rotation direction inverter switch. The version ... DL
is equipped with loose cable end.
Motor cooling
The cooling jacket with the overhead pressure connection
provides sufficient motor cooling even in sipping mode.
3.3.4. Impeller
The impeller is fixed on the engine shaft, which
powers it. The impeller is an open multi-channel impeller, for
drainage water containing soft solids with a maximum
diameter of 10 mm.
4. Package, Transport, Storage
4.1. Delivery
On arrival, the delivered items must be inspected for da-
mage and a check made that all parts are present. If any
parts are damaged or missing, the transport company or
the manufacturer must be informed on the day of delivery.
Any claim made at a later date will be deemed invalid.
Damage to parts must be noted on the delivery or freight
documentation.
4.2. Transport
Only the appropriate and approved fastening devices,
transportation means and lifting equipment may be used.
These must have sufficient load bearing capacity to ensu-
re that the product can be transported safety. If chains are
used they must be secured against slipping.
The personnel must be qualified for the tasks and must
follow all applicable national safety regulations during the
work.
The product is delivered by the manufacturer/shipping
agency in suitable packaging. This normally precludes the
possibility of damage occurring during transport and sto-
rage. The packaging should be stored in a safe place if the
location used is changed frequently.
4.3. Storage
Newly supplied products are prepared that they can be
stored for 1 year. The product should be cleaned thoroug-
hly before interim storage.

The following should be taken into consideration for
storage:
•
Place the product on a firm surface and secure it
against falling over. Submersible mixers and auxiliary
lifting devices should be stored horizontally, submer-
sible sewage pumps and submersible motor pumps
should be stored horizontally or vertically. It should be
ensured that they cannot bend if stored horizontally.
Danger from falling over!
Never put down the product unsecured. If the
product falls over, injury can occur!
•
The product has to be stored at a place free from vi-
brations and agitation to avoid damage from the ball
bearings.
•
It is also necessary to pay attention to the storage.
The device should be stored in dry rooms without
temperature fluctuation.
•
The product may not be stored in rooms where wel-
ding work is conducted as the resulting gases and ra-
diation can damage the elastomer parts and coatings.
•
It is responsible to take care that the corrosion coa-
ting will not be spoiled
•
Any suction or pressure connections on products
should be closed tightly before storage to prevent
impurities.
•
The power supply cables should be protected against
kinking, damage and moisture.
Beware of electrical current!
Damaged power supply cables can cause fatal in-
jury! Defective cables must be replaced by a quali-
fied electrician immediately.
Beware of damp!
Moisture penetrating cables can damage them and
render them useless. Therefore, never immerse cab-
le ends in the pumped fluid or other liquids.
•
The machine must be protected from direct sunlight,
heat, dust, and frost. Heat and frost can cause con-
siderable damage to propellers, rotors and coatings.
•
The rotors or propellers must be turned at regular in-
tervals. This prevents the bearing from locking and
the film of lubricant on the mechanical shaft seal is re-
newed. This also prevents the gear pinions (if present
on the product) from becoming fixed as they turn and
also renews the lubricating film on the gear pinions
(preventing rust film deposits).
Beware of sharp edges!
Sharp edges can form on rotors and propellers. The-
re is a risk of injuries. Wear protective gloves.
•
If the product has been stored for a long period of
time it should be cleaned of impurities such as dust
and oil deposits before start-up. Rotors and propellers
should be checked for smooth running, housing coa-
ting and damage.
•
After storage longer than one year the oil of motor
and, if necessary the gear have to be changed. This
is also necessary if the product never had run (natural
deterioration of mineral oil).
