MAINTENANCE
PERIODIC
The
1.Water quality varies considerably across the country. The water inlet filter, and spray atomizing nozzle may become clogged during operation. The frequency of this occurrence will depend on the quality of your water. The spray characteristics should be checked periodically to verify that a fine mist is being produced. During a normal operating cycle, remove the remote bracket (leave the speed nuts in place on the plenum). Verify that a fine mist is being produced when the
2.If the spray is weak or comes out in a narrow stream, it is an indication that the nozzle and inlet filter must be replaced. Neither of these parts can be cleaned without causing damage which will impair humidifier operation. Use only genuine Field Controls replacement parts. Replace the nozzle and inlet filter as often as necessary.
CAUTION: Close the saddle valve completely and disconnect the transformer from the receptacle prior to any service to the
3.To replace the nozzle, unscrew it from the nozzle adapter by securely holding the nozzle adapter with one wrench and loosen the nozzle with a separate wrench. Replace with a new nozzle using Teflon tape or other pipe thread sealant on the male pipe threads.
4.Replace the remote bracket onto the plenum as it had originally been attached.
5.To replace the water inlet filter, it is necessary to first remove the water supply tube from the water inlet fitting. Screw a small screw into the existing filter, and then pull the screw outward. This will pull out the filter element, which will allow the replacement with a new element. Then
6.Open the saddle valve completely and place the "ON/OFF" switch in the "ON" position.
SEASONAL
At the conclusion of the heating season, the following steps should be taken to ensure proper performance when humidification is desired once again.
1.Close the saddle valve completely.
2.Place the "ON/OFF" switch in the "OFF" position and disconnect the transformer from the receptacle.
3.Disconnect and drain the plastic tubing from the saddle valve to the water inlet, and from the water outlet to the remote bracket (nozzle inlet).
4.Check the drain tube connected to the remote bracket to ensure that it is empty.
5.Remove the remote nozzle bracket from the plenum, and replace the nozzle following the previously described procedure.
6.Replace the water inlet filter following the previously described procedure.
7.Remount the remote bracket to the plenum and

a.Check electrical receptacle for power.
b.Check air flow temperature within the plenum. If not 120o F, adjust furnace blower "ON" to a higher temperature, or attempt to locate a position which will satisfy the temperature requirement.
2.
a.Install an optional Air Booster Activator to prevent
b.The furnace blower controls can be adjusted to ensure that the blower operates for a longer period of time, or the
3.A light dust appears on furniture, registers, etc.
a.Some areas have high calcium, and mineral content in the water supply. The dust created as the water evaporates will not adversely affect any household effects. The problem can be minimized by installing an
