6.5. Check of Direction of Rotation
1 Ph-pumps do not require any check, as they always run
with the correct direction of rotation.
3 Ph-pumps must be checked for correct direction of rota-
tion before start-up. On original HOMA control boxes a
control-light is illuminated, if the direction of rotation is not
correct.
With smaller pumps the direction of rotation may be
checked by watching the start-jerk. Put the pump vertical
on the ground and lift one edge. Start the motor. Viewed
from above, the unit must jerk anti-clockwise, as the cor-
rect direction of rotation is clockwise. With bigger pumps
the check may also be done by watching the rotation of
the impeller through the discharge or the suction inlet.
With pumps already installed, the check may be done by
comparing head (pump pressure) and flow (quantity of
water) at different direction of rotation. The direction that
gives higher head and flow is the correct one.
If the direction of rotation is wrong, interchange two of the
phases of the electric power supply. Using an original
HOMA control box with CEE-plug, this may be done by a
180° turning of the small round pole-socket at the plug-
end with a screwdriver.
7. Installation
Pay attention to the maximum depth of immersion
(see pump label).
If the pump is installed in a sump, the sump opening
must be covered with a tread-safe cover after installation.
The operator has to prevent damage through the
flooding of rooms caused by defects of the pump through
the use of appropriate measures (e.g. installation of alarm
units, backup pump or like that).
7.1. Submerged Base Stand Installation
Some models of Barracuda GRP pumps have a base
stand casted at the pump housing. For other models a
separate ring base stand, which is available as an acces-
sory must be fixed at the bottom of the pump.
Fix a 90° elbow to the pump discharge. The pump may be
installed with a flexible discharge hose or a rigid pipe,
non-return valve and isolating valve. If a flexible hose is
used, make sure that it does not buckle.
Fix a rope or a chain to the pump handle and lower the
pump into the liquid. If the pump is installed on muddy
ground, support it on bricks to prevent it from sinking in.
7.2. Submerged Installation with Auto-Coupling
Permanent installation of the pumps can be done on a
stationary auto-coupling. The following instructions refer
to the use of the original HOMA system.
⇒ Place the auto-coupling base unit on the bottom of the
pit. Use a plumb line to fix the correct position of the
guide rail bracket on the inside of the pit cover. Drill
mounting holes and fasten the guide rail bracket provi-
sionally with 2 screws.
⇒ Put the auto-coupling base unit in the exact position and
fasten with expansion bolts to the pit bottom. If the bot-
tom is uneven, the base unit must be supported to be in
horizontal position.
⇒ Assemble the discharge pipe in accordance with the
generally accepted procedures and without exposing the
pipe to distortion or tension.
⇒ Insert the guide rails in the ring of the auto-coupling
base and adjust the length of the rails by cutting them
accurately to the guide rail bracket.
⇒ Unscrew the provisionally fastenend guide rail bracket,
fit it on top of the guide rails and fasten it to the pit
cover. Make sure that the guide rails do not have any
axial play, as this would cause noise during pump op-
eration.
⇒ Clean out debris from the pit before lowering the pump
into operation position.
⇒ Fit the coupling flange at the discharge of the pump.
Make sure that the rubber profile-seal is properly fixed to
the flange and will not fall off when the pump is lowered
into the pit. Slide the guide bar of the coupling flange
between the guide rails and lower the pump into the pit
by means of a chain secured to the pump handle. When
the pump reaches the auto-coupling base unit, it will
automatically connect tightly.
⇒ Hang up the end of the chain to a suitable hook at the
top of the pit.
⇒ Adjust the length of the motor cable, so that it is not
damaged during the pump operation. Make sure that the
cables are not sharply bent or pinched.
7.3 Automatic Float Switch Control
The pumps may be supplied with float switch level con-
trollers. They start and stop the pump according to the
liquid level in the pit.
The difference in level between start and stop must be
adjusted by adjusting the free swinging length of the ca-
ble between the float switch and the cable fastening.
Long cable end: Large difference in level.
Short cable end: Small difference in level.
The stop level must be adjusted in such a way, that the
pump stops before the liquid level is lowered below the
top of the pump volute.
The start level must in any case be below the bottom of
the liquid inlet pipe of the pit.
The high alarm level, if a separate float switch for that is
installed, should be adjusted approx. 10 cm above the
start level, in any case it must be below the bottom of the
liquid inlet pipe of the pit, so that the start level must be
adjusted accordingly.
Never place the float switch in the sump without fixing the
float switch cable to a fixed point i the sump, because the
float switch needs a rotation around the fixing point of the
cable to operate without any problems. Non-observance
may cause an overflow because the pump does not start
running or a dry run of the pump in fact that the pump
does not stop, which will destroy the pump.
Note: Only the proper adjustement and fixing of the float
switch cable will guarantee a reliable pump operation. Af-
ter any modification of the float switch adjustment the
function must be checked by a test-run of the pump.
8. Start-Up
Never let the pump run dry for a long time of period,
as it will destroy the pump (danger of overheating).
Start the pump, when the system has been filled with
liquid and vented. Open the isolating valves. Check the
position of the float switches. If necessary, check the di-
rection of rotation of the pump, as described under 6.5.
Put the switch on the control box to the required mode of
operation.
