PUMP DATA

WARNINGS

The pump may contain a small quantity of residual water from testing. It is advisable to flush briefly with clean water before final installation.

If the controller or motor is damaged, do not install or run the motor; or it may result in equipment damage or personal injury.
Take note of the technical data shown on the data plate.
The mains voltage must be the same as that shown on the motor plate.
Ensure the earth connection is properly done.

The pump should be installed in a well-protected and ventilated place.
The pump should never run dry.
The motor should not be wrapped in plastic bags due to risk of condensation.

Single-phase motors are provided with overload protection; they are connected directly to the power mains.

The pump should be turned off before repairing, to avoid accidents.

For DPL 1100VS,

Do not make a static voltage test of the controller, as it will cause damage to the controller.

AC input power must not be connected to output terminals U, V, W of the controller, as it will cause damage to the inverter.

Do not disassemble the cover when the pump is switched on, as it may result in possible electric shock.

When the controller is set on automatic fault reset or after power off, protection measures should be taken otherwise it may result in personal injury.

In the event of failure of the On/Off button, a separate emergency power-off button may be installed in the control system, otherwise, it may result in personal injury.

Do not touch the terminals of the controller, even in a shutdown state as the terminals may still be electrified, otherwise, it may result in possible electric shock.

Do not touch the heat sink, as it may be hot and cause injury.

The factory reset parameters have been programmed to meet customer requirements. Do not arbitrarily modify the controller parameters as it may cause equipment damage.

INSTALLATION

Installation, electrical connection, and commissioning must be carried out by skilled personnel in compliance with local safety regulations. Failure to comply with these instructions causes the risk to personal safety, damages the equipment, and validates warranty.

• Installations should be done on a firm flat base not exposed to flooding.

• Do not overtighten fittings into the inlet and outlet of the pump.

• For installation below water level, fill the pump slowly and completely open the valves in the suction pipe and on the delivery side expel the air.

• For installation above water level, use a shorter suction pipe to reduce priming time.

• Install the pump horizontally as close as possible to the edge of the pool.

• Provide adequate support for the suction and delivery pipes so that they do not weigh down on the pump. Do not make the couplings between the pipes too tight.

• Do not immerse the motor in water.
  

• To avoid problems in suction, make a positive slope of the suction pipe towards the pump.

• Ensure proper tools and equipment are used for all connections.

• Before starting the motor the first time or when the system is drained, the pump should be primed by opening the lid of the pump leaf basket and adding water to cover the basket.
  

• Weekly maintenance of the pump is recommended. It is important that pump and skimmer baskets are cleaned and any debris removed.

Installation assembly and disassembly must be performed by qualified personnel.

Any modification without prior authorization relieves the manufacturer of any kind of liability.

Ensure the power is off before connecting the wires or it may result in electric shock or fire.

Earth terminal should be grounded or the controller and the motor housing may be electrified.

Do not touch the main circuit terminals. The terminal wires must not make contact with the casing of the controller, otherwise, it may result in electric shock.

OPERATION AND MAINTENANCE

• Switch the pump/filter off before doing any maintenance, cleaning or other work.
• Only perform maintenance which is described in the instruction manual.
• All other work must be performed by a qualified person.
• In the interest of safety and reliability, only use genuine Dayliff spares, or else the warranty will become null and void.
• Refer to the Dayliff website espares.dayliff.com for spares support.
• Never run the pump dry i.e without water, as this will damage the impeller and shaft seal.
• Weekly inspection of the pump and filter is recommended.
• It is important that the pump and skimmer baskets are cleaned and any leaves or debris removed before back washing.
• Clean plastic parts with a damp cloth. Aggressive cleaning agents can damage plastic parts.
• Do not wash down the electrical components with water.
• The pump is equipped with thermal overload protection. If overload occurs during operation, the build-in overload protection automatically deactivates the pump. The pump will switch on automatically after a cooling period of approximately 3 minutes, ensuring the cause of the overload is identified and addressed.
• All work listed in this manual must be performed regularly. If this maintenance work cannot be performed by the end-user, an authorized person must be commissioned to perform this work. If these operations are neglected, faults may arise which are the responsibility of the user. These include;
  1. Damage to the motor, due to untimely or inadequate maintenance or cleaning of the cooling fan cover.
  2. Corrosion or other damage caused by incorrect storage of chemicals in the pump house.
  3. Damage due to the use of spare parts which are not original
  4. Damage due to maintenance and repair work not carried out by qualified technicians

Always wait at least 10 minutes after power off to ensure no residual voltage before maintenance and inspection, otherwise it may cause injury.

VARIABLE SPEED PUMP OPERATION

1. Name
2. The display window
3. The power indicator
4. The remote control signal receiver
5. 100% button: the maximum speed setting button (or timing enter button).
6. 80% button: 80% speed setting button
7. 50% button: 50% speed setting button
8. Speed increase button (or timing setting key) 10. Speed reduction button (or timer setting key)

Buttons and display

The pump operator panel is equipped with a 100% full speed button, 80% speed button, 50% speed button, switch button, speed increase, and reduction buttons.  The LED screen displays running speed or the maximum speed value corresponding to the percentage of the set speed. To set speed, press any corresponding speed button either 50%, 80%, or 100% then reduce or add as desired using the ▲▼ buttons.

Each dial on the buttons increases/ reduces speed by 5%.

Speed setting buttons
On pressing the speed buttons (100%/80%/50%), the LED screen displays the current set percentage (100%/80%/50%), after 1 second, it will flash 3 times for confirmation. After the system is confirmed, the LED shows the appropriate speed value. For example; if the rated speed of the motor is 2820rpm, after setting the speed to 80%, the LED screen will display 80.0; and will flash 3 times indicating set successfully, the display of the LED screen will also switch to speed value, like 2256.

Pump starting and stopping

• When the controller is powered, the motor starts immediately, otherwise, the pump needs to start with the start button.
• When the pump is not running on pressing the 100%/ 80%/ 50% button or ON/OFF button, the LED screen will display the setting for 3secs, then the motor will start working.
• When the pump is running, by pressing the STOP button, the controller will cut out the output power, and the motor will be slowly stopped. After the motor is stopped, it can only restart after 3secs.

High-speed Start Function
After starting at any speed, the motor will run for three minutes in high speed, within three minutes the power light shows red except for the ON/OFF button,  the other buttons do not function when pressed. After 3 minutes, the power light turns green from red indicating that the motor can be adjusted for speed. This is a factory setting and cannot be changed.

Memory function when power off
If the system suddenly loses power, the motor running status will be recorded by the system; If the power is restored, after three minutes of high-speed running,  the system will revert to the original operation mode.

Over/ Under voltage protection
The pump may not run if the AC voltage detected is more or less than the set Value, which is >190V but <270V.

Overload protection
If the operating current is more than the set value of 6.2A, the pump will stop running which is registered as a malfunctioning fault.

Locked rotor protection
Upon starting the pump, the current is monitored for 5secs, if the value exceeds the set value of 6.2A, the controller will stop the pump which is registered as a Locked rotor. After 10seconds, the pump will restart, the current is monitored again and if the situation persists three consecutive times, the motor will shut down completely which is registered as a malfunction of the pump. Rectify the fault and restart the pump.
IPM module
When IPM fails, the motor stops running immediately which is registered as a malfunction. The motor will then clear the fault automatically 30seconds later and restart. After three consecutive attempts, the pump will shut down and will need to be manually cleared/restarted before running.
