Filling The Spa; Preparation - BWT Spas ST 2.18 Notice D'installation Et Conseils D'utilisation

We recommend that a thermal magnetic circuit breaker be installed at the head of the line to protect
against over-voltages and short circuits. This can also act as a breaker to allow interventions on the
electrical components.

Filling the spa

Before filling the spa make sure that all the diverting valves are closed to ensure that there will be no leaks.
Vibrations during transport can cause the valves to open slightly.
Water quality:
Water from the house mains is the most reliable source. Well water should not be used due to potentially
high concentrations of phosphates, nitrates, iron, manganese and, possibly, bacteria. If using well water,
regular testing will be required.
If a water softener is available, fill the spa partially or entirely with softened water to avoid the build up of
calcium deposits on the walls.
If water is harder than usual (TH greater than 200 ppm), treat it immediately with a suitable chemical
(AQUACAL). Exposure to hard water can lead to yellowing of plastic components (nozzles, skimmers, air
controls, etc.) installed under the water line. Start treating the water as soon as the spa has been filled.
(see paragraph 6 - Water Treatment).

Preparation:

Open all the gate valves between the spa and the spa pack. Use the gate valve locking pins to hold the
valves open.
Check that the gravity drain valve is closed (handle perpendicular to the tube) and the cap is screwed
tightly onto the valve. Nota : leaktightness is ensured by the seal at the bottom of the cap.
Do not overfill the spa, it could overflow when users get in and cause irreversible damage to the ozonator.
Fill the spa with water, the water elvel should come up to the 'WATER LEVEL' mark engraved into the
skimmer frame when the spa is is occupied by its max number of users.
Check the water level regularly and adjust it if necessary.
Keep the spa covered while not use to prevent evaporation, heat loss and pollution.
