Direct start

The motor guard is set to the current (measured in ampere) that is stated on the identification plate. When

the thermal surveillance is connected, the motor guard's setting is increased by 10%.

Star-delta start

The motor guard is set to the current (measured in ampere) that is stated on the identification plate multiplied

by 0.58. When the thermal overload switches are connected add 8% to the calculated value.

The grid must be secured with ordinary safety cutouts.

Thermal protection:

All pumps are equipped, with thermal overload switches built into the stator. These are marked F0 & F1. The

thermal protection conductors must be connected in series with the motor guard in the extern control board.

If this protection is not connected the guarantee will be void in case of damage.

8. Operation.

Before start, the pump must be fully assembled and ready for operation, and this manual read through.

Before the pump is started, the rotation direction must be checked.

At start the motors starting torque will cause the pump to jerk. The start reaction will be counter-clockwise,

seen from the top of the motor.

The starting torque can be very powerful even with small pumps. Never hold on to the

pump and do not start the pump when hanging in free air.

Place the pump solid so it cannot rotate or tip over before starting.

Never start the pump without impeller, the pump must be fully assembled and ready for operation.

At wrong start reaction two phases must be switched at the extern control box.

Never start up a pump with incompletely connected cables or non-operational overload switches and

leakage sensor.

Let a qualified electrician do this job.

9. Service & maintenance.

Before any inspection, service or repair of the pump, it must be physically disconnected from the electrical

power supply. Remove connectors or dismount the wires on the electric board.

(Any emergency stop can be released or be defective and start the pump by mistake)

All pumps require regular control and preventive maintenance to operate economically and reliably.

The pump should be checked every 6 months and during possible extreme operating conditions more often.

For complete overhaul of the pump contact an authorized DanPumps A/S workshop, or your local

DanPumps A/S dealer.

Clean the pump carefully before dismantling it. Follow local and national safety instructions.

Service Instructions for the S-WP pumps.

Type W - Wet Pit Installation

Install on a guide rail system, with a quick-release discharge connection bracket (DCB). The DCB is bolted to

the floor of the tank / well. The volute is equipped with an adapter to guide the pump via two 2" guide rails, to

secure connection on the DCB.
