Grundfos alldos pump manual

Page Electrical Connections Observe the local safety regulations! Warning The pump housing must only be opened by personnel authorised by Grundfos! Warning Protect the cable connections and plugs against corrosion and humidity. Only remove the protective caps from the sockets that are being used. Page Commissioning 3. Switch on the power supply. The connections must be carried out according to these instructions. Page Electronic Diaphragm Leakage Sensor 9. Connect the screen at one end to PE.

Page Integral Relief Valve Integral relief valve Warning When dosing dangerous media, observe the If the pump is the only pump in the system, the integral relief Wear protective clothing gloves and goggles valve optional protects the complete discharge side of the when working on the dosing head, connections discharge line system from an excessive pressure build-up.

For this purpose, send the pump to Grundfos or 8. Start up the dosing system. Tighten the screws on the top part of the relief valve after To ensure trouble-free operation, it is recommended to have the 48 operating hours. Page Replacing The Diaphragm For transport or cleaning, the venting cartridge Caution must be closed.

If possible, rinse the dosing head, e. Page Fault Finding Chart Leaking suction line. Replace or seal the suction line. Rinse or replace the suction line. Alternatively, the pump can also be insulated manually in accordance with standard insulating requirements for heating and cooling systems fig. If a non-return valve is fitted in the pipe system fig. This is especially important in proportional-pressure control mode reduced head at low flow. The closing pressure of a single non-return valve is accounted for in the pump settings as the minimum head delivered is 5 ft 1.

Only Grundfos-approved external antennae may be connected to this product, and only by a Grundfos-approved installer. The pump must be installed in such a way that it is not stressed by the pipework.

The pump may be suspended direct in the pipes, provided that the pipework can support the pump. Twin-head pumps are prepared for installation on a mounting bracket or base plate. To ensure adequate cooling of motor and electronics, the following must be observed:. C and D. To ensure adequate cooling, the control box must be in horizontal position with the Grundfos logo in vertical position. If the pump head is removed before the pump is installed in the pipework, pay special attention when fitting the pump head to the pump housing:.

Gently lower the pump head with rotor shaft and impeller into the pump housing. Make sure that the contact face of the pump housing and that of the pump head are in contact before the clamp is tightened. The warning symbol on the clamp holding the pump head and pump housing together indicates that there is a risk of personal injury. See specific warnings below. Carry out the electrical connection and protection according to local regulations.

Check that the supply voltage and frequency correspond to the values stated on the nameplate. Never make any connections in the pump control box unless the electricity supply has been switched off for at least 5 minutes.

The ground terminal of the pump must be earth ground. Grounding or neutralization can be used for protection against indirect contact. If the pump is connected to an electric installation where a Ground Fault Circuit Interrupt GFCI is used as additional protection, this circuit breaker must trip out when ground fault currents with DC content pulsating DC occur.

The voltage tolerances are intended for mains voltage variations. They should not be used for running pumps at other voltages than those stated on the nameplate. TM03 TM05 - TM05 Concerning demands on signal wires and signal transmitters, see section Technical data. To be used for external control of the pump or as sensor input for the control of the external setpoint. The 24 V supply from pump to sensor is optional and is normally used when an external supply is not available.

The pump incorporates two signal relays with a potential-free changeover contact for external fault indication. The function of the signal relay can be set to "Alarm", "Ready" or "Operation" on the pump control panel or with the Grundfos GO Remote.
