The compact kit must be below the Spa level. This avoids having to prime the pumps. The maximum difference in level is 2 metres below (h ≤2m).
Spas with overflow have a balance tank, which has a double function:
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.
Recirculating circuit connection
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 tape. Under no circumstance should you use metal accessories or tubing, which could seriously damage the plastic components.
Connection between Spa – Compact Kit
If your spa has a spa floor cleaning connection; connect the floor cleaning outlet with the filter pump inlet making the connection in parallel with the other inlets to this pump. You must place a ball valve between the outlet and the pump which will normally remain closed.
Connection between Compact Kit – Spa
Connect the heat exchanger with the Spa filter return sleeves.
Installation of level sensors
In order to ensure that the recirculating circuit always contains water, you must install the level sensors on the outside of the balance tank. These will control the opening and closing of a filling solenoid valve.
Look at the following diagram.
| So | Safety probe | A | Network water inlet |
| SMIN | Mínimum level probe | B | Deposit overflow |
| SMAX | Maximum level probe | C | Spa overflow water inlet |
| EL | Electric control box | D | Water outlet towards filtration |
| EV | Electric valve (not included) | Ht | Total height |
S0 sensor has to be placed above the bottom outlet pipe.
Smin sensor has to be placed above S0 sensor.
There must be more water than the volume displaced by all bathers between Smin and Smax. Smax has to be placed below the top drain..
The level sensors have to be attached to outer side of the balance tank.
The system will be automatically blocked when water level is below so sensor.
The electric valve (EV) will be activated (the tank will start filling) when the level drops to below SMIN and will be deactivated when it exceeds SMAX.
If you do not install level sensors, follow the next diagram.
SPA WITH SKIMMER
Connection Spa – Compact Kit
If your Spa has the ozone option, follow the instructions indicated in the Ozonator installation sheet now.
For the selector valve connections, always use plastic accessories, gasket and Teflon tape. Under no circumstance should you use metal accessories or tubing, which could seriously damage the plastic components.
Connection Compact Kit– Spa
Connect the heat exchanger outlet with the Spa’s filter return nozzles, placing a check valve in this connection.
Water massage circuit connection
Connect the pipe to the water suction drains with the inlet to the massage pump (each pump will suction the water of 2 drains). Connect the outlet of each of the massage pumps to the connections in the Spa battery that will guide the water to the jets. Place a ball or guillotine valve in the inlet and outlet of each pump.
Air massage circuit connection
Leave the air pump inlet free and connect the pump outlet to the Spa’s corresponding connection.
Note: It is essential to install a 150mm siphon above the maximum water level and to place a check valve between the siphon and the Spa.
