3.4. Explosive Environments
For operation of the pumps in explosive environments
only models with explosion-proof motors (model Ex) must
be used.
For each individual installation the explosion classifi-
cation (Ex-class) of the pump must be approved by the
local authorities.
4. Warranty
Our warranty only covers pumps which are installed and
operated in accordance with these Installation and Opera-
tion Instructions and accepted codes of good practice and
being used for the applications mentioned in these in-
structions.
5. Transportation and Storage
Never use the cable or the discharge hose/pipe to lift,
lower, transport or attach the pump. Always use the han-
dle or a rope or a chain attached to the handle.
The pump may be transported and stored in vertical
or horizontal position. Make sure that it cannot roll or fall
over. For longer periods of storage, the pump should be
protected against moisture, frost or heat.
6. Electrical Connection
Before operation, an expert check must secure that
the required electrical protection measures exist. The
connection to ground, earthing, isolating transformer, fault
current breaker or fault voltage circuit must correspond to
the guidelines set forth by the responsible power plant.
The pump must be connected to a socket-outlet with
earthing contact. If the pump is used in a garden pool a
fault current breaker with a released nominal current up to
30 mA must be installed. The required line failure protec-
tion must be installed.
The voltage required in the technical data sheet must
correspond to the existing line voltage.
Submersible pumps used outside of buildings must
have a cable with a minimum length of 10 m.
Make sure that the electrical pin-and-socket connec-
tions are installed flood- and moisture-safe.
Before starting operation check the cable and the plug
against damages.
The end of the pump power supply cable must not be
submerged in order to prevent water from penetrating
through the cable into the motor.
The normal separate motor starter/control box of
standard as well as of explosion proof pumps must not be
installed in explosive environments.
6.1. Connection of 1 Ph-motors
Pumps with 1 Ph-motors must be connected to a sepa-
rate control box with motor starter and operating capacitor
(not valid for CH 406, CH 412, with integrated start relay
in the motor), available from the HOMA accessory pro-
gram. If any other control unit is used, make sure that the
thermal relay in the motor starter is set according to the
nominal current consumption of the pump motor (see
data on pump label).
For capacitor sizes, see table below.
Pump type Operating Capacitor
µF V
AC
CH 410, CH 411 20 450
CH 446-1,0/4W 40 450
CH 426-1,5/2W 50 450
CH 446-1,5/2W
6.2. Connection of 3 Ph-motors
Pumps with 3 Ph-motors must be connected to a sepa-
rate control box with motor starter, available from the
HOMA accessory program. If any other control unit is
used, make sure that the thermal relay in the motor
starter is set according to the nominal current consump-
tion of the pump motor (see data on pump label).
Motor Start
The pumps are designed for direct-on-line (DOL) start. All
motors with 400 V voltage indication on the pump label
have their motor windings internally star-connected for
operation at 400 V / 3 Ph power supply. The motor cable
wires indicated U, V, W must be connected to the power
supply wires indicated L
1
, L
2
, L
3
through the motor starter
according to fig. 1.
6.3. Temperature Sensors
The pump types CH 426, CH 446 and the single phase
models CH 410, CH 411 have a set of temperature sen-
sors built in the stator windings. The contact of these
sensors opens in case of overtemperature and switches
off the motor power supply. Standard models of TP
pumps with temperature sensors are available upon re-
quest.
Single phase models of 1 Ph-motors up to 1,6 kW have
the sensors (built in upon request) internally connected,
so that no external connection to the control box is nec-
essary. When the motor cools, it is switched on again
automatically.
Standard models of 3 Ph-motors have the sensors (built
in upon request) connected to the motor power supply
cable, the wire ends marked T
1
and T
3
. They must be
connected to the safety circuit of the control box in order
to provide an automatic re-start of the motor, when the
motor cools. The switch-off temperature of the sensors for
standard models is approx. 130°C.
Explosion proof models (3 Ph) have a set of lock-out-
device temperature sensors with a higher switch-off tem-
perature of approx. 140°C, connected to the motor cable,
the wire ends marked T
1
and T
2
. They must be connected
to the safety circuit of the control box in order to provide a
manual re-start, when the motor cools. This can be done
by switch-off the mains power supply and switch on again
after approx. 5 minutes.
6.4. Oil Chamber Seal Condition Sensors
Upon request CH 426 and CH 446 pumps are available
with a moisture sensor device of the pump oil-chamber. It
measures the electrical resistance of the oil in the cham-
ber. In case of water entering the chamber through the
shaft seals, the resistance will change.
