Description

The BADU Jet countercurrent unit can be used with any type of pool. A high- output jet pump is connected to the fiberglass housing via a suction and pressure pipe. The housing is attached on the edge of the pool. Water is sucked in by the jet pump at low velocity via inlets on the housing and then injected into the pool under high pressure via the nozzle. The activation and de-activation of the jet pump is controlled by a pressure switch, installed on the housing. The power of the flow can be regulated by means of the adjustable nozzle*. Air can be added to the water jet through the air-intake.

Filling the Unit and Start-up

• With BADU Jet impulse, click the massage hose onto the nozzle of the unit, then push a hose (e.g. garden hose) into the nozzle of the massage hose. Cover the remaining opening with your hand. Open air drain valve* on the pump and fill unit with water through the garden hose. Make sure that the unit is well aerated. As soon as water seeps out of the air drain valve, close valve and remove garden hose and massage hose.

• With BADU Jet Standard, insert water hose (e.g. garden hose) into the nozzle of the unit and cover the remaining opening with your hand. Open air drain valve on the pump and fill unit with water. Be sure that the unit is sufficiently aerated. As soon as water seeps out of the air drain valve, shut valve and remove water hose.

• With BADU Jet swing and BADU Jet action, unscrew the red filler plug and fill unit by means of a water hose or a watering can (approx. 20 liters). Once the pump is filled put red plug back in place and tighten carefully by hand. The pump will now prime.

• Press position switch (n° 27 in the spare-parts figure) and briefly switch unit ON and OFF with push button in order to check the direction of rotation of the motor. Note the directional arrow on the pump. In case of incorrect direction of rotation, switch 2 phases.* 6.3 Put cover back into position and tighten. When assembling, mind the position switch!**

• After verifying that all pertinent rules and regulations have been observed, start unit by means of push button.

• Filling up of the BADU Jet active Version 2
  The air in the pump is removed and replaced with water using the vacuum hose and the pump of the filter installation. This is done as follows: After having secured the BADU Jet onto the edge of the pool.
  ATTENTION: For the priming/aeration to be effective the air regulation knob MUST be closed.

• Fill the vacuum cleaner hose with water by pushing it in the water vertically. Then place one end onto the nozzle of the counter current unit and place the other end, making sure the hose is still filled with water, on the skimvac in the skimmer.

• Turn on the filter pump. The filter pump will now suck in water through the jet unit hereby drawing out the air that is trapped in it and replacing it with water. As the air from the jet unit reaches the filter pump there may be a momentary drop in the flow through the filter pump. Remove the vacuum hose from the skimvac and keep the end of the hose under water. Wait a short while until the filter pump has re-primed. Place the hose back on the skimvac again and repeat this process as often as is necessary to fully aerate the jet unit. It is thereby useful to allow the fIlter pump to run for a while, so as to warrant a thorough aeration.

• ATTENTION! If you have an overhang filtration system with a non-self priming filter pump, fill the pump according to manufacturers guidelines using the overhang skimmer and priming plate. Proceed to activate the fIlter pump. After having carefully aerated and filled the vacuum hose, attach one end to the nozzle of the jet unit and the other to the overhang skimmer of the running filter unit. Push the skimmer down slightly when reattaching the cover. Now the jet unit is being filled / aerated by the filter system. If the water flow is interrupted because air has been taken in, repeat the above process. It is advised to pump water through the jet for approximately 1 minute. Then turn the filter pump off and remove the hose.

• The BADU Jet unit is now ready for use and can be switched on.
  IMPORTANT: Make sure that the air regulation is always closed during aeration, as this can result in an intake of air and a failure to prime the pump.

Electrical Connection

Model SPOT with underwater floodlight *

This model – in contrast to the basic unit – has additional

• Extended housing
• Separately included isolating transformer 12 V, 300 VA / 12 V A.C. 50 VA
• Built-in underwater floodlight with 300 W, 173 mm dia. / 50 W, 100 mm dia.
• Junction box with isolating transformer terminal

The isolating transformer which has been tested in accordance with VDE 0551 or EN 60742, respectively, comes with a potted 2 m power cord. It has a thermal overload switch as well as short-circuit protection and has a potted cable of 10 m length on the secondary side. The transformer itself is watertight when sprinkled with a hose. The 300 W lights have been tested according to DIN VDE 0711 Part 1 and/or EN 60598-2-18, respectively. Existing safety regulations demand that a temperature sensing switch be provided inside the light housing. During prolonged operation of the 300 W light it may switch off automatically and – after having cooled off – come on again automatically. These lights are operated at 12 V and are therefore harmless. Before replacing a defective light bulb the entire unit must be pulled out of the pool.

Electrical Connection

1. The isolation transformer must be installed outside the protected zone (at least 3.5 m away from the pool edge). An ON/OFF switch for the light must be provided at the installation site.
2. The light cable is pre-assembled inside the junction box of the isolation transformer and is joined with the bipolar cable of the isolation transformer at the terminals.
3. The underwater light should only be operated under water.

Exchanging the light bulb
For technical reasons the 300 W light bulb must be exchanged together with the light assembly. To make sure that the light bulb is defective, i.e. that it was not just switched off by the thermostat (see part 8 of the Operations Manual), the light should be switched on again after approx. 30 minutes.
When removing the light unit proceed as follows:

1. Switch unit OFF at the housing.
2. Disconnect pump and light from the power supply.
3. Undo the cover
4. Remove unit from the pool edge.
5. Pull unit from the pool and lay it down.
6. Detach light cable from the junction box and pull it out.
7. Remove the two screws at the light mantle
8. Pull light assembly together with connecting cable from the housing.
9. Return light assembly to your dealer – or directly to the manufacturer – for replacement.
10. Reassemble the light assembly in reversed order.
