Water connections
The plumbing system (including connectors, gate valves, etc.,
2-
2a-3-3a
) for connecting the Hot tub to the Spa-Pak and the balance
tank, must be set up by the installer.
The Customer must provide the ground drainage points (
2-2a-
3-3a, detail 28 and 29
) of suitable dimensions, which can be inspect-
ed for any cleaning, and to which the low-point drain ø 50 mm (
2-
2a-3-3a, detail 3
), the loading/overflow of the balance tank and the
drain from the filter are to be connected.
Spa-pak “booster kit”:
in the instance where a spa-pak “boost-
er kit” is also installed, it must be connected to the drainage sys-
tem; refer to the relative documentation.
CAUTION! Before preparing the ground drainage points,
consult the local authority for the regulations that control
the drainage of chemically treated water.
In particularly cold areas, to avoid the risk of any remaining water
freezing
(water that may remain in plumbing after emptying the sys-
tem)
it is advisable to install valves for the complete drainage of plumb-
ing (
2-2a-3-3a, detail 31
).
To fill the spa, you can use a garden hose, or provide connections to the
plumbing system of the home as shown in
2-2a-3-3a, detail 11
.
IMPORTANT: the 3/4” solenoid valve on the balance
tank (for automatic filling of water level) must always be
connected to the water system that supplies the system.
Any connections to the drinking water system (other
than the recommended ones) must be carried out
according to EN1717 regulations, using “AA”, “AB” or
