FOR CALIFORNIA INSTALLATIONS: • California regulations require the control setting to yield 4,000 grains of capacity per pound of salt. To meet these requirements, the SALT PER REGEN and CAPACITY must be set no higher than indicated below: Model Capacity Default Salt Default GNPR40L 16.5 KGr 4.0 lbs GNPR48L 15.2 KGr 3.6 lbs 12 Installation Instructions SYSTEM CAPACITY INPUTS SALT PER REGEN AND CAPACITY (CONT.) NOTE: Both SALT PER REGEN and CAPACITY inputs must be based on the SYSTEM CAPACITY INPUTS CHART. How to determine correct salt dosage and capacity: The correct salt dosage and capacity are determined based on the family size and water hardness. Use the following procedure and example: • Daily Water Usage = number of persons in household x 80 gallons For a family of 3 Daily Water Usage = 3 x 80 = 240 gallons/day • Water Hardness – have the water tested or call your local water company. For this example, 20 grains is assumed. • Calculate total grains used per day = gallons/day x hardness = grains/day 240 gallons/day x 20 grains = 4,800 grains/day • Water softener should be set to regenerate every 5 days. Req Capacity = 5 days x 4,800 grains/day = 24,000 • Use SYSTEM CAPACITY INPUT table to select capacity and determine lbs of salt per regeneration. For GNPR40 use setting at 24,000 grains. • Program the control: Capacity: 24,000 grains Lbs of Salt: 7.0 If water supply has a high level of sediment or iron, set system to regenerate every 3 days: • Use the UP or DOWN button to select SALT PER REGEN. • Press the SET button. • Use the UP , DOWN and LEFT buttons to select SALT PER REGEN amount. • Press the SET button to accept. • Use the UP or DOWN button to select CAPACITY. • Press the SET button. • Use the UP , DOWN and LEFT buttons to select correct capacity. • Press the SET button to accept.

The 7.5 lbs (GNPR40L), 15 lbs (GNPR40L), 9 lbs (GNPR48L) and 18 lbs (GNPR48L) are certified using the 4 bump injector. 13 Installation Instructions MANUAL REGENERATION Occasionally you may find it necessary to initiate a manual regeneration. This is done by pressing the REGEN button on the front of the display. When you press the REGEN button, the control performs a full regeneration of the water conditioner immediately. In the event the system is allowed to run out of salt, it will be necessary to run “Back to Back” regenerations. This can be done easily by pressing the REGEN button one time, waiting at least one minute and pressing the REGEN button again. NOTE: The second regeneration will begin immediately after the first is completed. “Back to Back” regenerations are necessary if full exhaustion occurs due to low regenerate levels or system malfunction. The system works on a highly efficient proportionate-brining method. When the system is not aware of the lack of proper regenerate (salt), a larger portion of the resin bed becomes exhausted. REGEN button NORMAL OPERATION The control will cycle between TIME OF DAY and CAPACITY about every 10 seconds, as indicated by the green indicator light. Capacity in Normal Operation mode is the gallons of water available until the next regeneration cycle. During a regeneration cycle, the control will cycle between TIME OF DAY and REGEN TIME REMAINING. REGEN TIME REMAINING is the number of minutes until the regeneration cycle is complete. ERROR CODES This system continuously monitors itself and displays an error message if it detects something wrong. This typically happens when the valve has not advanced through the regeneration cycle properly. When an error is detected, the display shows the letters “Err” with a number from 1 to 4. The table on page 24 describes each error, the cause of the error and the solutions. To clear the error from the display, press any button on the control. If the error still exists, the control will display the error message again after 30 seconds. SOUNDS YOU WILL HEAR During the regeneration cycle, the softener makes several sounds. These sounds are normal. • Clicking sound – This occurs as the valve assembly advances. It is the opening and closing of the valve ports. • Harmonic sound – As the valve transitions between cycles in regeneration, a high-pitched harmonic noise may be heard for a few seconds. • Water flow sound – In the backwash and purge portions of the regen...
