* Prepare a drain hose with a plastic shut-off valve if water needs to be removed from the unit
or water may freeze in the unit in cold areas. Remove the drain cap on the back of the unit
and attach the plastic joint, vinyl or PVC hose and plastic shut-off valve. Drain outlet is 3/4"

Drain Cap
* Put the Salt Water Hose through the Cap (Accessory) and push in the Salt Water Hose until
the Stopper hits the Cap. See Fig. 25. In case of using a larger tank, install the Salt Water
Hose so that the filter on the Salt Water Hose can reach the bottom of the tank.
Note: Install the piping so that the outlets are located above the Salt Water Filter on the end
of the Salt Water Hose. Due to the siphon phenomenon, salt water may leak from the
outlets if they are not high enough. See Fig. 26.
