18. NOW TAKE THE OPPORTUNITY TO CLEAN THE INTERIOR OF THE TANK, THE BAFFLE, AND OTHER

COMPONENTS WHICH MAY HAVE SCALE OR DEPOSITS. REMOVE SCALE WITH A WIRE BRUSH OR

SOFT EMORY CLOTH. BE CAREFUL NOT TO DAMAGE THE PRINTED CIRCUIT BOARD OR THE SMALL

TEMPERATURE PROBE IN THE BOTTOM OF THE TANK.

19. Before inserting the new element, use the needle nose pliers to gently unbend the 90° spade

connectors to a 45° angle. This will make it easier to insert the new element.

20. Place a new fiber washer onto each hub and, insert the element into the tank and through the holes.

Make sure the spade connectors are pointing to the left as you view the front of the tank.

21. Place a new metal washer over each hub and then the hex nuts. Use a 3/4” wrench as a back up, on the

hub of the element inside the tank. Use a 3/4” socket to tighten each hex nut quite snugly, for a leak proof

seal. CAUTION: Do not over tighten and damage the fiber washers. 60 Ft. Lbs. torque.

22. Use needle nose pliers and gently bend the spade connectors back to a 90° angle.

23. Re-connect the wire connectors to each element spade connector. Make sure they are tight

24. Make sure that no other wire connectors came loose off of the printed circuit board. Double check

and tighten or re-connect any and all connections to the printed circuit board and the new element.

NOTE: Loose spade connectors can overheat and damage the wires. Use pliers to re-tighten the spade

connectors and do not allow line and load wires to cross over each other. Doing so will void your warranty.

25. Place the printed circuit board back into position and align the threads on the water probe to the hole on

the printed circuit board. Re-insert all screws on the printed circuit board which were removed in step #13.

26. Thread the nut back onto the end of the water probe where it protrudes through the printed circuit board.

Adjust the back nut as necessary for a snug fit on the printed circuit board.

CAUTION: Make sure that the water probe is pointing directly down into the water tank at a 90° angle.

Now hold the probe end with your left hand while you tighten the nut against the board.

Achieve a snug and tight fit. Once again insure that the probe is pointing straight down into the tank.

Loosen the nut and re-adjust if necessary.

27. Before you place the front plastic cover back on, double check to make sure that you have not missed any

electrical connections to the board. Also make sure that no wires are being pinched.

28. Align the front cover and slowly push it over and onto the printed circuit board. Make sure that the LED’s

align up with the holes in front. Tighten all 4 screws.

29. Re-insert the stainless steel baffle into the tank and, secure with the 2 phillips screws.

30. Insert the humidifier back into the duct and, secure with the 1/4” hex screws removed in step # 9.

CAUTION: Make sure the unit is level and plumb.

31. Put some teflon tape onto the threads of the brass drain assembly and screw the entire assembly back onto

the drain connection of the humidifier. CAUTION: Do not hand tighten or use the solenoid valve as leverage.

Doing so will damage the valve. Use an adjustable wrench at the brass “T” to tighten.

32. Plug the automatic drain valve wire connector back into the side of the front cover until it clicks into place.

33. Re-insert the green low voltage terminal block at the top of the front cover.

34. Re-connect the overflow drain hose and the automatic drain hose.

35. Re-connect the 1/4” water supply line and open the valve.

36. Plug the humidifier into the 120 volt or 220 volt outlet.

37. If the humidistat setting is high enough, the unit should start to fill with water.

38. Once the water level is correct, the “HEATER” LED should illuminate.

39. Observe the humidifier through several cycles to insure proper operation.

40. If the humidifier malfunctions, review all of the above steps to make sure that nothing was overlooked.
