Connection
The input for the untreated water is on the left, the output for the demineralized water for the closed
loop hydronic system is on the right. See Fig. 1 below.
The equipment contains a non-return valve. When the connections are closed, the untreated water
cannot flow through the apparatus.
Puropal-Pro may only be under pressure for the duration of the filling process. A permanent
connection under pressure is not permitted. Under normal domestic water pressure the flow rate
through the Puropal Jr. Pro is approximately 6.6 gpm (25 l/min).

Connections
Open the drain valve on the cartridge only when replacing the resin and only if a hose is connected
to the collection sack. Under no circumstances should you connect the drain valve to a water supply
system.
Empty the water content of the cartridge once before each use since bacteria can build up between
uses. Check to ensure there are no resin pellets in the water.
