Royal ESP 620 Niro - Surface pump EINHELL - Free user manual and instructions

USER MANUAL Royal ESP 620 Niro EINHELL

Before start-up, note the following!

●The pump can be connected to any shock-proof plug which has been installed according to regulations. The plug must have a supply voltage of 230 V \~ 50 Hz. Fuse min. 6 Amp.

Caution!

When the pump is to be used near swimming pools or garden ponds and in their area of protection, it must be equipped with a ground-fault circuit Interruptor with a nominal trip current of max. 30 mA (according to VDE 0100, part 702 and 738). The pump must not be operated while people are in the swimming pool or in the garden pond! Please contact your electrician!

Attention!

(Important for your own security) Before starting to run your new submersible pump, please have the following items checked by an expert:

●Ground connection
●Zero conductor
●Fault current breaker switch must correspond the safety regulations of the power plants and they must work faultessly.
●The electrical connections must be protected from moisture.
- If there is danger of looding, the electrical connections must be taken to higher ground.
●Circulation of aggressiv fluids, as well as the circulation of abrasive materials must be avoided at all costs.
●The submersible motor-driven pump must be protected from frost.
●The pump must be protected from running dry. Access on the part of children should also be prevented with appropriate measures.

Consistency

Your submersible pump is designated for the circulation of water with a maximum temperature of 35^ C. This pump may not be used for other fluids, especially motor fuels, cleaning fluids, and other chemical products!

Installation

The submersible motor pumps is installed as follows:

●In a stationary position with fixed pipeline or
●in a stationary position with a flexible hose pipe.

Please note!

You should never install the pump by suspending it unsupported from its delivery pipe or power cable. The submersible motor pump must be suspended from the specially provided handle or be placed on the bottom of the shaft. To guarantee that the pump works properly, the bottom of the shaft must be kept free of sludge and dirt of all kinds.

If the level of water sinks too far, any sludge in the shaft will dry out quickly and stop the pump from starting up. It is necessary, therefore, to check the submersible motor pump regularly (by carrying out start-up tests).

The floater is adjusted in a way that the pump can immediately be started

Note!

The pump shaft should have minimum dimensions of 40 x 40 x 50 cm, so that the floating switch can move freely.

Mains supply

Your new submersible pump is equipped with a shock-proof plug according to regulations. The pump is designed to be connected to a 220/230 V \~ 50 Hz safety socket. Make sure that the socket is sufficiently secured (min. 6 Amp.) and is in excellent condition. Introduce the plug into the socket and the pump is ready to go.

Important Note!

If the mains cable or plug suffers any damage from external action, repairs to the cable are prohibited.

Important!

This work may only be performed by a qualified electrician or your ISC GmbH Customer Service.

Setting to work

After having read these instructions carefully, you can set your pump to work, reconsidering the following items:

• Check if the pump rests on the ground of the shaft.
  ●Check of pressure cord has been attached properly.
  ●Check if electrical connection is 230 V \~ 50 Hz.
• Check if socket is in good condition.
  ●Make sure that water and humidity can never come to the mains supply.
  ●Avoid pump running dry.

GB

Important! Note!

• Remove the mains plug before all maintenance work.
  ●In the event that the pump is often transported in the course of operation, it should be cleaned out with clear water after every use.
  ●In case of stationary installation, the function of the loating switch should be checked every 3 months.
  ●All fibrous particles which may have built-up inside the pump housing should be removed with a water jet.
  ●Every 3 months the shaft ground and as should be cleaned from mud.
• Remove deposits on the floater with clear water.

Cleaning the impeller

If excessive deposits collect in the pump case you must dismantle the bottom part of the pump as follows:

1. Undo the 4 screws from the bottom of the intake cage.

2. Remove the intake cage from the pump case.

3. Clean the impeller with clear water.

Important! Do not put down or rest the pump onthe impeller!

1. Assemble in reverse order

Setting the ON/OFF operating point

The ON and OFF operating point of the float switch can be set by adjusting the float switch in its latching holder.

Before you put the pump into operation, please check the following:

●The float switch must be installed so that the level of the ON operating point and the level of the OFF operating point can be reached easily and with little force. To check this, place the pump in a vessel filled with water, raise the float switch carefully by hand and then lower it again. As you do so, note whether the pump switches on and off.
●Make sure that the distance between the float switch head and the latching holder is not too small. Proper operation is not guaranteed if the gap is too small.

- When you set the float switch, make sure that it does not touch the base before the pump switches off. Caution! Risk of dry-running.
