7/33 4. Safety This manual includes important information concerning installation and operating the pump. Persons who are involved in installation or/and operation of the pump, should read and understand these instructions before installation or starting the pump. There are live parts inside the frequency converter of the SC -pump, when the supply voltage is connected. Incorrect installation of SC –pump may cause damage to the pump or bodily injuries, even death.
8/33 4.4 Safety instructions for inspection and assembly It is user’s responsibility to ensure that persons who carry out inspections and installations are qualified experts and familiarized themselves with these instructions carefully. 4.5 Operating the pump Working safety of the delivered pump and related devices can be ensured only if these devices are operated according to the section 1.2 Fields of application and 1.3 Limits of application and use of this manual.
9/33 5.1 Positions for installation Allowed positions Not allowed positions 5.2 Electrical connections ATTN! All electrical work shall be carried out by qualified electrician approved by the local authorities. Supply voltage may be connected with standard cable, screened cable is not required. Ensure the nominal voltage of the electric motor corresponds the local supply voltage.

12/33 5.3.4 SCB-pump – constant pressure between the pump flanges Applications Systems, where are variations in the flow and where pressure losses are generated mainly on the consumption equipment. Heating circulation, where the pressure loss on the heat equipment is small. Accessories Pump, frequency converter, 2 pcs of pressure transmitters installed to the pump flanges.
13/33 required reference value can be adjusted by the potentiometer. It is saved by pushing SET –button. By pushing button MODE twice, starting situation is achieved. When pump is running, the present motor current (A), feedback (%) or frequency (Hz) can be selected to the display by pushing SET-button. Unauthorized operating of the display can be prevented by locking it by pushing MODE –button 2 seconds.
14/33 5.3.7 SCCVAK-pump - constant pressure between supply- and return-line with controller of the frequency converter in use Operation principle (reference for pressure difference 0-10 VDC from external control system) The level of the constant pressure difference between the inlet- and outlet-line of the system can be adjusted by external control system (reference for differential pressure 0-10 VDC).
15/33 5.3.9 SCF-pump - constant temperature Applications Heating and cooling systems, where the constant temperature is required by adjusting the flow. Accessories Pump, frequency converter and temperature transmitter (and sensor). Operation principle The level of the constant temperature in discharge can be adjusted by the buttons of frequency drive (parameter 133).
16/33 5.3.10 SCG-pump - controlled by external system Applications Systems, where are variations in the flow and/or where the flow is controlled mainly with the pump. The pump is controlled by an external system or controller. Accessories Pump and frequency converter. Operation principle The speed reference for pumps is given from external control system, external controller, process control, etc ATTENTION!! If the external control system is not in use when pumping is needed, PU / EXT COMBINED...
17/33 6. Service, spare parts and troubleshooting The pump doesn’t need any regular servicing. As a shaft seal is used an adjustment free mechanical seal. It is a wearing part which has to be replaced if it starts to leak. Note that few drops leakage per hour can be quite normal especially when coolants (eg.
