This humidifier is subject to a one (1) year limited warranty issued and guaranteed by the manufacturer. This warranty is void if the unit is damaged by careless handling, improper installation, non-standard operating conditions, or improper maintenance. This warranty is limited to repair or replacement of the humidifier at the discretion of the manufacturer. No other warranty is offered or implied. This warranty is not transferable. All warranty claims must be accompanied by a receipt or record of installation. 

1. Selecting a Location If mounted on the COLD air side, air is supplied to the humidifier with a flexible duct connected to the air take-off (with sliding damper) mounted on the HOT AIR SUPPLY coming out of the furnace. If mounted on the HOT air side, air is supplied to the humidifier after coming out of the furnace. It is the returned to the furnace with a flexible duct connected to the air take-off (with sliding damper) mounted on the COLD AIR SUPPLY. Follow the instructions on the humidifier TEMPLATE to locate and cut holes for the humidifier and take-off. The COLD air return is preferred for the Desert Spring Humidifier. Mount the take-off so that the damper can be easily opened and closed. The Desert Spring Humidifier does not wet the furnace filter.

2. Assembly Install the float into the slot in the side of the basin. Hand tighten the nut.

Install the drain into the bottom of the basin and tighten retaining nut securely. Finger tighten these parts ensuring that the drain does not turn. Do not over tighten. Screw the cap onto the drain. Optionally, connect a length of garden hose which extends to a floor drain. The humidifier can be configured with either a right or left side air supply. Which is used will depend upon the layout of your furnace.* Snap the motor plate and inlet into the basin. Ensure that the basin tabs on these parts fit into the corresponding slots in the basin. To remove the motor plate and inlet, squeeze the lower tab with pliers and pull upwards.

3. Hanging the Basin Hang the basin from the mounting hanger. See template for instructions on how to mount the hanger. Use screws to fix the basin to the hanger. Start the screws in the pilot holes and drive them through into the back of the bracket.

4. Electrical Connections (Model DS3200)

• Do not solder on the humidistat
• Mount the humidistat according to the guidelines supplied in the humidistat box.
• Before making electrical connections ENSURE THAT THE POWER IS OFF! (Model DS3200) Connect the motor leads as shown below.

SOURCE OF 110 VOLTS A.C. BEST Power to Furnace Motor:   humidifier will only operate when furnace does ALTERNATIVE A.C. from Household Wiring:   humidifier will operate when humidity is low but will be most effective when the furnace is on

5. Water Connections

• Use of softened water is not required.
• Before starting TURN OFF THE WATER SUPPLY and relieve the pressure.
• Install the saddle valve on a copper water line as close to the humidifier as possible.
• CAUTION: ensure that the piercing pin is backed up into the valve body. If installing on galvanized pipe, predrill a ¹/₈-inch diametre hole that the piercing pin fits into.
• Assemble one side of the top clamp to the bottom clamp and place over the water line ensuring that the rubber gasket is in place over the piercing pin.
• Assemble the other side of the top clamp to the bottom clamp with remaining fastener and tighten evenly until unit is firmly attached to water pipe.
• Connect supplied plastic water line to valve and float as shown below. Use the plastic compression fitting and insert in the valve end of plastic line; use the expander in the float end. If using copper line, use metal compression sleeves.
• Turn the valve handle clockwise fully to pierce the water pipe. This is the off position.

 
 
 
 

6. Installing the Disk Wheel Using the tabs as indicators, lower the disk wheel assembly into the V-guides on the inlet and motor plates. Ensure that the inlet end of the axle is seated in the bearing at the bottom of the V-guide and that the gear on the other end of the axle is engaged with the motor gear. DO NOT rotate the disk wheel manually as damage to the motor could occur.

7. Installing the Lid and Adjusting the Water Level Fit the lid onto the basin. Turn on the water supply and check for any leaks. The float assembly should be adjusted so that the height of the water is within the range indicated by the textured bands on the inside sides of the basin. The water should just cover the disks (look into the inlet to see the water level). Adjust the float as required. Secure the float adjustment nut with a 9/16-inch wrench. As an additional convenience, you may wish to run a hose from the overflow hole to your floor drain. The necessary parts are available from your local plumbing supplier.

8. Connecting the Air Supply  Use one of the supplied wire clamps to hold the flex ducting to the air take-off. Use the remaining wire clamp to secure the flex duct to the humidifier's inlet. For maximum efficiency, do not let the flex duct sag. If you need to, trim the length of the flex duct ensure that you cut the ends square. If the humidifier is far enough from the take-off to cause strain on the ducting, it may be necessary to buy a longer flex duct at your local hardware store. Ensure damper is in the open position. Running the Furnace with the hose attached to it will allow the hose to stretch and reach further

9. Startup, Maintenance and Shutdown

• Turn on the water supply to the humidifier (if it has not been previously done), turn on the electrical power and adjust the humidistat so that the humidifier starts. Adjust humidistat to the desired setting. Regularly change the setting in accordance with the outside temperature.
• At the end of the humidifying season, turn off the water, remove the disk wheel, agitate the water in a circular motion and drain the sediment and any water from the basin. Reposition the disk wheel and lid. Turn the humidistat off. Slide the damper to the closed position.
• Under normal conditions, minimal maintenance should be required. If you live in an area where the mineral content of the water is high (hard water), you may wish to drain the sediment as described above and periodically clean any minor sediment deposits from the basin and disk wheel. Use vinegar or any cleaner approved for plastic.
• After soaking in vinegar or cleaning solution, the disk wheel should be rinsed.
• Over time metal parts may discolour. This is a normal reaction and will not affect performance.
• For excessive mineral buildup, lower water level using ball valve and scoop minerals out. Hardened minerals will break off cleanly with minimal effort.
