How to use
1. Comprueba que la presión de tu red está entre 3 y 6 kg; lo óptimo son 4 bar. Por debajo de 40 psi añade el kit de bomba de presión (ref 422113).
2. Coloca el equipo en vertical y bien sujeto, cerca de la toma de agua y de un desagüe.
3. Conecta la entrada a la red, la salida de agua osmotizada al depósito y el tubo de rechazo al desagüe.
4. Abre el agua despacio y revisa que no haya fugas en las tres carcasas.
5. Deja correr el agua 10-15 minutos antes del primer uso para enjuagar los filtros.
6. Cambia el pack de filtros 10" (422102) y la membrana 150 GPD (422106) cada 4.000 litros.

Frequently asked questions
-
There are 3: a sediment filter that retains particles, a coconut carbon filter that removes 99% of the chlorine (which is what destroys the membrane), and the reverse-osmosis membrane, which is the stage that reduces EC, removing 95% of salts and heavy metals.
-
It produces 20 liters per hour, that is, 500 liters a day, a flow rate suited to grows of 1 to 2 tents. If you need more, the next step up is the Mega Grow 1000 with 40 l/h.
-
At 25 degrees, with an inlet pressure of between 3 and 6 kg (the optimum is 4 bar) and reference water of 500 ppm TDS. Outside those conditions, output drops, so it's worth keeping in mind before buying.
-
The reject ratio is approximately 2:1. Every reverse-osmosis system produces reject water, so you'll need to plan a drain for that outflow when setting up the installation.
-
The 10-inch filter pack (ref. 422102) plus the 150 GPD membrane (ref. 422106), replaced every 4,000 liters. Remember that filter packs are not interchangeable between units: there are 10-inch, 10 PL, and 20-inch formats.
-
You can add the pressure pump kit (ref. 422113), compatible with this unit: if your inlet pressure is below 40 psi, it raises it above 60 PSI and has a built-in pressure switch. It should not be used for more than 3 hours in a row.
