Iberspa Oasis 40 Manuel D'utilisation Et D'installation page 31

Spas with overflow have a balance tank, which has a double function:
• Absorbing the water displaced by the people who enter the Spa.
• Ensuring the filtration pump is never left without water.
To correctly install this tank, it should be placed as near as possible to the Spa, below the
level of the overflow, so that the overflow can evacuate all the water.
KIT TO SPA CONNECTION
Use a hard pipe or flexible hose of an appropriate resistance. Check the regulations in
force in each country.
You must use the same pipe diameter as that of the Spa's connection; these diameters are
sized for optimal performance of the kit. Use the right glue for each material. In any case,
it will be necessary to minimize the installation of elbow fittings and pipe length to reduce
the drop of pressure in the installation.
The Spa's connections with couplings are marked with stickers indicating the circuit and
the water flow direction.
Before and after each pump and on the heat exchanger outlet, place a ball or guillotine
valve for carrying out maintenance or replacements on these elements.

SPA WITH OVERFLOW
Spa Connection – Balance Tank
Connect the overflow pipes to the balance tank. The pipes should be sloping
sufficiently to ensure the water evacuates by gravity. Under no circumstance should
siphons be created that could prevent water circulation. The diameter of the pipes
for collecting water from the overflow should be calculated in such a way that the
water does not exceed the recommended speed by the regulations in force. Connect
a drainpipe in the upper part of the balance tank; its function is to evacuate possible
excess water preventing the deposit from overflowing. Connect the balance tank
outlet with the filter pump suction, placing a check valve between the deposit and
the pump.
The outlet will have to be placed below or at the same level as the bottom of the
balance tank. Spa with overflow
Connection between Balance Tank – Compact Kit
Connect the filter pump outlet to the filter's selector valve (depending on the kit model,
this connection may already been made). Connect the selector valve outlet with the
water inlet of the heat exchanger (depending on the kit model this connection may
already be made). If your Spa has the ozone option, follow the instructions indicated
in the Ozoniser installation sheet now.
For the selector valve connections, always use plastic accessories, gasket and Teflon
