Priming The Pumps - BWT Spas ST 2.18 Notice D'installation Et Conseils D'utilisation

Nota bene:
The main drains through which water flows from the spa to the drain valve are located on a
vertical wall just above the lowest point of the spa shell. This means that, after draining, a few centimetres
of water will remain in the bottom of the spa. Similarly, some water may remain in the pipework.
Consequently, if the spa is to be left empty for a long period of time, we recommend that you undo the
pump unions to completely drain the spa, and that you carry out a Chlorine shock treatment upon refilling
the spa (see paragraph 6 - water treatment).

Priming the pumps

The spa pack is equipped with one or two pumps depending on the model. Prime the pumps before using
the spa:
1.
Cut the power supply to the spa
2.
We recommend that you remove the filter cartridge from the skimmer to facilitate priming of the two-
speed pump (see paragraph 5.1).
3.
For each of the pumps do the following,
− Loosen the barrel union located on the pump suction line (horizontal pipe) in order to allow air to vent
until water flows from the barrel union.
− Tighten the union.
4.
Reconnect the spa power supply
5.
Press the 'Jets' button on the control pad to start the pumps. The pumps should prime and a burst of
air should issue from the massage jets. For more information, refer to the control pad instructions.
6.
Replace the filter cartridges once the two-speed pump is primed.
If one of the pumps does not prime, stop the spa and redo this procedure for the pump in question.
