3. TRANSPORT AND STORAGE

When taking delivery of the equipment, check that
it has not been damaged in transit. If anything is
found wrong, take the necessary steps with the
carrier within the allowed time.
If the equipment delivered

4. PRODUCTS AND ACCESSORIES
4.1 The pump
The circulating pump SB-4Y TEMPUS (FIG. 1)
has been specially designed to operate in drin-
king/process water circulation systems.
Thanks to the appropriate selection of materials
and design, it will not corrode when in contact
with process water.
Motor protection is not required, since the motors
are of the non-overloading type.
The pump is fi tted with a digital timer and a
thermostat for constant temperature control in
the circulation system.
The version SB-4Y TEMPUS is a compact,
ready-toinstall solution with a ball shut-off valve
fi tted directly on the suction side and a non-return
valve on the discharge side, which are normally
required for installation within a circulation pipe-
line system.
4.2 Functions of the pump
Timer function
The SB-4Y TEMPUS offers a timer that can be
used to programme three "on" and "off" times.
Factory settings : 24 hour continuous operation;
Temperature control is switched off.
Blocking protection
When the SB-4Y TEMPUS is switched off using
the timer function, the pump switches on auto-
matically every 60 minutes for 10 seconds, to
minimise blocking through calcination. (Automatic
function, cannot be switched on/off).
Temperature control
A temperature setting of around 55 °C, for exam-
ple, signifi es that the SB-4Y TEMPUS maintains
the warm water temperature in the return of the
drinking water circulation system using the inte-
grated temperature sensor.
Thermal disinfection
In addition, the SB-4Y TEMPUS offers a routine
for the recognition and support of boiler thermal
disinfection switching. This boiler function invol-
ves heating the drinking/warm water storage
tank to approx. 70 °C on a weekly basis. Since
the circulating pump is switched off at night, a
routine is required that recognises the
heating process and activates the pump inde-
pendent of the timer setting.
When the SB-4Y TEMPUS is connected to the
mains voltage for the fi rst time, the pump starts
a teach-in phase, independently of the timer
setting, of at least one week, to recognise a
possible temperature increase in excess of 68 °C
in the system (if the function is activated). During
this teach-in phase, the pump switches on for
10 minutes every 20 minutes. If a temperature
increase occurs, the time is recorded and the
pump continues to run until the next tempera-
ture increase. The time difference between both
temperature increases is the teach-in frequency
for thermal disinfection (TD). This means: Thanks
to this teach-in routine the SB-4Y TEMPUS
recognises when a TD of the boiler occurs and
switches on automatically for approx. 2 hours (in
continuous mode) to support
the TD in the circulation system.
Changes to the timing of the TD performed are
recognised and corrected automatically.
4.3 Scope of delivery
- Ball shut-off valve and non-return valve,
- Integrated timer and temperature control,
- Installation and operating instructions.
4.4 Accessories
Accessories must be ordered separately :
- Reserve motor suitable for each pump housing
of the same design,
- Threaded or soldering union nuts.
5. INSTALLATION
Install the pump in a frost-free/dust-free and well-
ventilated location that is protected from adverse
weather conditions.
5.1 Mounting (See FIG. 1)
Risk of damage to the pump !
ATTENTION!
Dirt can cause the pump to
malfunction.
Do not install until all welding and soldering
work has been completed and the pipe system
has been fl ushed (if required).
- Mount the pump in an easily accessible location
with gate valves at both suction and discharge
sides in order to facilitate subsequent inspec-
tions or replacements.
- It may be necessary, depending on the appli-
cation to replace the spring discharge-side gate
valve with a spring-activated non-return valve.
- The gate valves are not required on SB-4Y
TEMPUS as their functions are assumed by
the integrated nonreturn and ball valves.
- Install the pump without voltage with the pump
shaft in a horizontal position.
- Observe the installation positions (FIG. 2).
Risk of damage to the pump !
ATTENTION!
The screwed cable gland
(FIG. 1 - item 3) must point downwards to
prevent water easily penetrating the motor
housing. If necessary, rotate the motor
housing after releasing the union nut
1 - item 4). Do not damage the housing gas-
ket.
- The directional arrow on the pump housing
shows the direction of fl ow.
- On the SB-4Y TEMPUS the non-return valve
(FIG. 1 - item 1) is screwed into the dishcarge
port, whilst the ball shut-off valve (FIG. 1 - item
2) is screwed into the suction port.
- The ball valve is open when the slot is in line
with the direction of fl ow.
- The ball valve is closed when the slot is per-
pendicular to the direction of fl ow.
5.2 Electrical connection
The electrical connection must be
made by a qualifi ed electrician and
comply with applicable local standards.
REMARK : To guarantee availability of the
pump
functions it is recommended not to connect the
pump to the boiler controller.
The pump has a power reserve of approx. 3
hours after power failure. The power reserve only
becomes active after 24 hours of operation when
fi rst installed.
- The electrical connection must be carried out
via a fi xed connection cable fi tted with a coupler
or allpole switch with a contact opening width
of at least 3 mm.
- To ensure that the PG connector is protected
from dripping water and has suffi cient strain re-
lief, be sure to use a connection cable with ade-
quate outer diameter (e.g. H 05 W-F 3 G1,5).
