8. Installing the automatic valve and the float (Please see Fig. 4, 5 and 7)
Kit No. 2 contains all the material you need to install the automatic valve.
•
Choose the side of the humidifier that is the best suited to your application.
•
Install the valve (7.1) inside the casing and fasten it with the hexagonal plastic nut (7.4). Make sure the valve is in a vertical
position.
•
Slide the water pan into the humidifier, the wide plastic tab towards the rear of the unit.
•
Take the float (7.3) and install it behind the valve lever (7.2) with the pivot pin (7.5) fitted in the round hole.
•
Insert the screw (7.6) in the kidney-shaped opening through the valve lever (7.2) and the float arm (7.3) and screw it into
the nut (5.7) installed in the hexagonal housing of the float arm.
•
Partially tighten the screw (7.6).
•
Once the valve is installed, block the opposite oblong hole with the flat black plastic plug (4.6) supplied in Kit No.1.
9. Connecting the water supply tubing to the humidifier (Please see Fig. 7)
Please ensure that operations 9, 10, and 11 are completed in sequence.
The plastic tubing MUST be kept away from hot surfaces (e.g. the warm air duct or the exhaust vent). Please measure carefully
before cutting.
IMPORTANT : Rough up both ends of the plastic tubing (approx. 1 inch long) with sandpaper in a rotating action.
•
Slip the plastic compression nut (7.9) onto the tubing, then the rubber sleeve (7.8), and finally fit one of the brass inserts (7.7)
(1/2" long, supplied with the brass valve) into the end of tubing.
•
Push the tubing fully into the automatic valve, tighten the plastic compression nut securely by hand, then add 1/2 turn with a
small wrench, without stripping.
10. Installing the supply valve on a copper pipe (Please see Fig. 13)
A plastic bag contains a brass valve and all the material required to install the supply valve. The water supply is taken from the
nearest cold water pipe suitable for the supply valve installation. Shut off the main water supply valve.
CAUTION : Please make sure that the piercing needle is completely recessed into the valve body by turning the handle
counterclockwise.
•
Assemble one side of top clamp (13.1) to bottom clamp (13.2) with a screw (13.3) and a nut (13.4).
•
Make sure that the rubber gasket (13.5) is in place over the piercing needle and position the valve assembly on
the copper water line.
•
Assemble the other side of the top clamp (13.1) to the bottom clamp (13.2) with the remaining screw and nut.
•
Tighten the two screws so that the valve is firmly attached to the water pipe. The two sides of the clamp must be parallel.
•
Turn the valve handle completely clockwise until it stops. This will pierce the copper pipe and close the valve.
•
This saddle valve is designed to be fully open or closed. Do not use it to regulate the water flow.
11. Connecting the water supply tubing to the supply valve (Please see Fig. 13)
•
Slip the brass compression nut (13.9) onto the plastic tubing, then the nylon sleeve (13.7) with its most tapered end
towards the end of tubing.
•
Fit the second brass insert (13.8) (1/2" long, supplied with the brass valve) into the end of tubing.
•
Push the tubing fully into the supply valve. Then tighten the brass compression nut with a small wrench, without stripping.
•
NOTE : The brass sleeve (13.6) supplied with the brass valve is to be used only if the plastic tubing is replaced by copper
tubing (optional).
12. Installing the drum
•
The drum shaft has a flat end (14.6) that fits into the motor. The opposite end of the shaft snaps into position in the centre
of the air collar.
13. Adjusting the water level (Please see Fig. 7)
The water level is adjusted by altering the height of the float. The optimal water level in the pan is at 3/4" from the top of the water pan.
•
Open the main water valve then the supply valve installed on the water pipe.
•
Loosen the screw (7.6) and adjust the float in such a way that it closes the automatic valve when the water level reaches 3/4"
from the top of the water pan.
•
Tighten the screw (7.6) when achieved.
•
Wait until the automatic valve completely closes and check all fittings. If necessary, tighten the compression nuts a little more,
without stripping.
