The SI1800, Si-82 or SI-1801centrifugal monobloc pumps are designed for use with all kinds of Air conditio-
ning units, refrigeration display cabinets, fan coil units and gas condensing boilers. They can also be used
with gas fired furnaces. The pump can be used to remove acid condensates (pH > 2.5) and condensates
with a temperature of up to 65°C.

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 and/or placed in areas of high humidity or where
the ambient temperature conditions are below freezing.
- The appliance is not to be used by children or persons with
reduced physical, sensory or mental capabilities, or lack of
experience and knowledge, unless they have been given
supervision 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 damaged, 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 supply cord without a plug, a means for disconnection must be incorporated to the
fixed wiring in accordance 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 (Fig.10)
Connect the cable to the mains network in accordance with local wiring rules.
-
b/ Safety switch connection (Fig.10-11)
(3)
IMPORTANT (EU): The high level safety switch comes with a dry contact rated NC at 250 V at 1 A inductive
and 4A resistive.
IMPORTANT (USA): High level safety switch comes with dry contact NC to be connected only to class 2
(1) (3)
circuit not to exceed 42V peak.
(2) (4)
We recommend to use this contact to cutout the application, preventing condensate overflow (Fig.10).
To modify the safety switch type, refer to Fig. 11.
c/ Hydraulic connection (Fig.7-8-9)
The pump unit should be installed horizontally, where the condensate drain pipe can enter into one of the
4 Ø30 mm (1 3/16'') inlet holes at the top end of the pump. The discharge connection is made through
the check valve, to which a tube of Ø int.10 mm (Ø 3/8'') should be fixed. For Ø int. 6 mm (Ø1/4'') pipe, a
Ø 6 x Ø 10 mm (1/4'' x 3/8'') adaptor can be used. In this case, the flow will be reduced. The acceptable
curvature of the tube's radius is 60 mm max. (2 3/8''). To fit or dismantle the valve tube, it is preferable to
withdraw the check valve beforehand.
d/ Installation / Settings (Fig.6-9)
The pump can be installed either on the ground, on a wall (drilling template supplied on P.14-15) or
hanging from the ceiling, using the fixed slot holes on the casing (to hang the pump from the ceiling it is
necessary to use 4 threaded rods + nuts as well as the drilling templates shown on P.14-15). It is possible
to choose the side of the water exit. Reversible pump block.To ensure proper ventilation of the motor, the
pump must be free of any obstruction. Be careful not to bend the flexible discharge tubing. A reinforced
tube can be used. For the reduction in flow due to pressure loss, consult the flow chart.
When the pump is installed with a boiler (
water (pH<6.5). Internal discharge recommended, to avoid freezing pipes.
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 safety switch operation, continue to pour water into the pump until the safety switch is set OFF
(use a testing meter).
b/ Cleaning.
The pump must be disconnected from the mains power supply before any maintenance work is carried
out. The inside of the pump should be cleaned regularly. Remove the tank and clean it with a mild cleaning
solution (such as water with 5% bleach). At the same time, check that the float is clean and free to move.
Re-install the tank and re-check the operation (
3/ TROUBLESHOOTING
If your pump is running continuously, check :
1) Discharge lines are not frozen, obstructed or kinked
2) The check valve is not blocked
If your pump is running abnormally (on and off quickly), check that the check valve is not damaged.
If your pump is not starting, check the wiring and power supply (Fig.10).
