19Routine MaintenancePROTECT THE WATER SOFTENER FROMFREEZINGIf the softener is installed where it could freeze (sum-mer cabin, lake home, etc.), you must drain all waterfrom it to stop possible freeze damage. To drain thesoftener:1. Close the shut-off valve on the house main waterpipe, near the water meter or pressure tank.2. Open a faucet in the soft water pipes to vent pres-sure in the softener.3. Move the stem in the single bypass valve to bypass.Close the inlet and outlet valve in a 3 valve bypasssystem, and open the bypass valve. If you wantwater in the house pipes again, reopen the shut-offvalve on the main water pipe.4. Unplug the power supply at the wall outlet. Removethe softener’s top cover, together with the salt lid.Take off both drain hoses if they will interfere withmoving the softener into position over the drain.5. Carefully remove the large holding clips at the sof-tener inlet and outlet. Separate the softener fromthe plastic installation adaptors, or from the bypassvalve.6. Lay a piece of 2 inch thick board near the floor drain(See Figure 39).7. Move the softener close to the drain. Slowly andgently, tip it over until the rim rests on the woodblock with the inlet and outlet over the drain. Do notallow the softener’s weight to rest on the inlet andoutlet fittings or they may break.8. Tip the bottom of the softener up a few inches andhold until all water has drained. Leave the softenerlaying like this until you are ready to use it. Plug theinlet and outlet with clean rags to keep dirt, bugs,etc. out.Floor Drain FIG. 39Wood BlockFIG. 38CapO-ring SealScreen SupportScreenGasket*Flow Plug (HVDC)HousingFerruleNutCone Screen*Flow Plug*Install with letteredside up, concaveside down.CLEANING THE NOZZLE & VENTURIA clean nozzle & venturi (See Figure 38) is a necessityfor the water softener to work properly. This smallcomponent creates the suction to move brine from thebrine tank, into the resin tank. If it should becomeplugged with sand, silt, dirt, etc., the water softener willnot work, and hard water will result.Nozzle & Venturi DiscIMPORTANT: Be sure small hole in the gasket is cen-tered directly over the small hole in the nozzle & ven-turi housing. Be sure the numbers are facing up.To get access to the nozzle & venturi, remove thewater softener’s top cover. Put the bypass valve(s)into the bypass position. Be sure the water softener isin soft water (service) cycle (no water pressure at noz-zle & venturi). Then, holding the nozzle & venturihousing with one hand, unscrew the cap. Do not losethe o-ring seal. Lift out the screen support and screen.Then, remove the nozzle & venturi disc, gasket andflow plug(s). Wash the parts in warm, soapy waterand rinse in fresh water. Be sure to clean both the topand bottom of the nozzle & venturi disc. If needed,use a small brush to remove iron or dirt. Do notscratch, misshape, etc., surfaces of the nozzle & ven-turi.Carefully replace all parts in the correct order.Lubricate the o-ring seal with silicone grease andlocate in place. Install and tighten the cap by hand,while supporting the housing. Overtightening maybreak the cap or housing. Put the bypass valve(s) intoservice (soft water) position.Recharge the softener to reduce water level in thetank. This will also assure that the softener is com-pletely recharged and ready to provide softened wateragain. Check the water level in the tank by lookingdown the brinewell. If the water level does not dropafter a recharge, the problem has not been resolved.Contact us at: info@northstarwater.com
