ENGLISH
SI1830 model condensate removal pumps are monoblock centrifugal pumps. They are designed to remove charged and/or aggressive condensates. They are parti-
cularly suitable for fuel oil and gas fired boilers (the condensates of which do not have a pH ≥ 2 and which do not exceed a maximum temperature of 80°C), cold store
cabinets, console units, evaporators and refrigerated display cabinets.

WARNING
- This pump has been designed for use with water only.
- This pump has been designed for indoor use only. It must not
be immersed. The pump and the entire discharge pipe must be
protected from freezing.
- The appliance is not to be used by children or persons with
reduced physical, sensory or mental capabilities, or lack of ex-
perience and knowledge, unless they have been given supervi
-
sion or instruction.
- Children should be properly supervised to ensure they do not
play with the appliance.
- In case of breakdown, in particular if the supply cord is dama
-
ged, it must be replaced by a Sauermann service agent or a
similarly qualified person in order to avoid any hazard.
- For models fitted with a power cable without a plug, a means
for disconnection must be incorporated to the fixed wiring in ac
-
cordance with local wiring rules.
WARNING:
Risk of electric shock. This pump is supplied with a
grounding cable and a grounding attachment plug.
To reduce the risk of electric shock, ensure that the
pump is connected only to a suitable grounding device.
1/ START UP.
a/ Mains connection.
Connect the power cables to the mains as shown in Fig. 2 & 11
(do not forget to ground the pump) through an electrical isolation
and protection device (not supplied) complying with the IEC 345
standard on the live and neutral wires.
b/ Safety switch connection.
IMPORTANT: The high level safety switch comes with a dry
contact rated NC at 250 V at 1 A inductive and 4 A resistive.
We recommend using this contact to cut out the A/C appliance,
preventing condensate overflow.
c/ Hydraulic connection.
The pump unit should be installed horizontally (Fig. 4), where
the condensate drain pipe can enter into one of the 1 Ø24 mm
inlet holes at the top end of the pump. The discharge connection
is made through the check valve, to which a tube of Ø10 mm
(Ø3/8“) ID should be fixed (fig.5). The acceptable curvature of
the tube’s radius is 50 mm max (Fig. 10). ALL PIPE CONNEC-
TIONS MUST BE SECURED WITH A JUBILEE CLIP/CABLE
TIE. To connect the valve tube, it is preferable to withdraw the
check valve beforehand.
d/ Installation / Settings.
The pump must be installed in its specific reservoir (Fig. 8),
or in a reservoir with a maximum height of 70 mm. (Fig. 7)
The reservoir should be installed horizontally and may be faste-
ned down via its two fixing lugs - Fig. 6 (template and fastening
screws supplied). It is possible to choose the side of the water
exit (reversible pump block Fig. 9). Ensure the flexible discharge
hose is not bent during installation (Fig. 5). For the reduction in
flow due to pressure loss, consult the flow chart.
2/ USE.
a/ Operation
Pour water into the pump. Check that the pump starts and stops
once the water level begins to fall. To check the high level alarm
operation, continue to pour water into the pump until the alarm
contact switch is set off (use a testing meter).
In normal operation, the pump operates at a maximum accor-
ding to the mode S3 -15%: 1sec ON / 5sec OFF or 2sec ON /
38sec OFF.
b/ Cleaning.
The inside of the tank should be cleaned regularly. Remove the
pump from the reservoir and clean it with a mild cleaning solu
-
tion (such as water with 5% bleach). At the same time, check that
the float is clean and free of foreign matter (A - Fig. 3). Re-install
the tank and re-check the operation, including the start, stop and
alarm. NB: The pump must be disconnected from the mains power
supply before any maintenance work is carried out.
3/ SAFETY.
- The safety switch will prevent condensate overflow (cut out of
compressor demand).
- Thermal overload protection (integrated into the pump): cut out
at 120°C
- Fire rated plastic enclosure.
