Resumen del manual
Soaking the tray in vinegar or a lime-removing agent is helpful when trying to remove stubborn mineral deposits. For trays with granular coating: Do not scrape off the granular coating, but lightly scrape out any mineral deposits and clean the “V” notches. This textured surface helps ensure even water flow for maximum performance. See page 3 if removed. 6. Slide the Water Panel evaporator (7) out from the plastic Scale Control Insert (8). Clean the insert frame by twisting and flexing it to loosen the calcium deposits, or use a putty knife. Inspect the Water Panel evaporator (Stock No. 35 for Model 560) and substitute a new one if necessary. Slide the pad back into the insert frame with the colored spot up and snap the distributor tray back into place. 7. Inspect the plastic feed tube by gently flexing it and looking for cracks or signs of wear. Replace tube if it is cracked, brittle, or has been damaged. 8. Re-install the Water Panel evaporative assembly into the unit by fitting its drain into the round receptacle at the base of the unit. Push the assembly in at the top against the beveled tabs that will hold it in place. Push the end of the feed tube back firmly into the nozzle and replace the front cover. 9. Remove the drain hose (9) from the bottom of the unit and flex it to loosen the internal mineral deposits. Then flush it with water under pressure and slip it back onto the black drain fitting. Make sure the drain hose has a constant downward slope and is not flattened or blocked. 10. Turn on water supply. 11. Check system operation: Manual Humidistat: Turn up humidistat to highest setting and make sure the furnace blower is operating. Humidifier will operate if RH is less than 50%. Humidifier Control: Check system operation by setting the knob to “Test.” With furnace blower operating and furnace calling for heat, humidifier will operate for one minute. 12. Set humidistat or Control to its original position. - 16 MAINTENANCE INSTRUCTIONS for APRILAIRE HUMIDIFIER MODELS 760-768 WARNING! 120 volts may cause serious injury from electrical shock.
