INSTALLATION INSTRUCTIONS (continued)

Prepare Humidifier for Mounting

Unpack carton.. Open front panel by removing screw and lifting panel up and away from humidifier.. Disconnect three wires from top of canister by pulling straight up.. The two large wires are the electrode conductors.. The smaller wire is connected to the high water level sensor.. Remove canister by twisting and pulling it up and out of drain assembly.. Remove two screws on right side of humidifier and lift side panel off housing to expose electrical compartment..

INSTALL Steam Dispersion TUBE

Note: If humidifier will deliver steam via the Model 850 Fan Pack instead of the dispersion tube, follow instructions included with Fan Pack..

Make sure steam dispersion tube is mounted higher than the humidifier so that condensate that forms in the tube runs back into the canister.. If the dispersion tube cannot be mounted higher than the humidifier or if the steam hose must extend up from the humidifier then down to the dispersion tube due to an obstruction, a drip tee and drain trap system must be installed as shown in Figure 4..

Drill a 1-1/4” diameter hole in a vertical surface of the duct at the location chosen for the dispersion tube.. Position the tube so it is angled up.. Secure with four sheet metal screws provided..

Mount Humidifier

Secure humidifier to wood surface using screws provided, or to sheet metal duct.. If mounting to stud frame wall, install two spanner boards to studs and fasten humidifier to spanner boards.. Make sure humidifier is mounted plumb..

Verify that the o-ring is in place in the slot in the drain assembly.. Dampen the o-ring with water, then reinsert canister.. (Do not use oil, grease or any lubricant besides water..) Rotate the canister so the caution label is visible.. Reattach the electrode conductors (interchangeable) and the high water level sensor wire..

INSTALL Steam HOSE

Six feet of steam hose is provided with the humidifier.. If the steam hose must be cut, use a hacksaw.. If additional length is required, use

1” O..D.. metal or copper pipe.. Do not use PVC pipe for steam line. Insulate pipe with 1” thick fiberglass to reduce steam loss.. See Table 3 for humidifier capacity at various lengths of steam hose and pipe..

Use the steam hose provided.. Other hoses may have impurities which can cause foaming in the canister.. Foaming can cause water level inaccuracies and reduced steam production.. When using pipe, remove all traces of residual materials used to connect the pipe to prevent foaming..

Attach steam hose to dispersion tube and then to top of canister using hose clamps provided.. Make sure steam hose has a constant slope of at least 2” per foot between the dispersion tube and the humidifier.. Any and every low spot in the steam hose or pipe must have a drip tee and drain trap.. Fill drain trap with water before making final connections..

Supply Water

Plumb the humidifier to cold tap water.. Do not use hot water because unheated supply water is used to cool water drained from the humidifier. To operate properly, water conductivity must be within the range of 125 to 1,250 uS/cm (micro Siemens per centimeter), which is roughly equivalent in hardness to 3 to 36 grains per gallon.. Do not use demineralized water.. The humidifier will produce steam immediately as long as the mineral content of the water is within the specified range.. For proper operation, supply water pressure must be between 25 psi and 120 psi..

Supply water piping must be free of oils, lubricants, solder flux and other contaminants, which can cause foaming in the canister that can lead to water sputtering from the dispersion tube into the duct..

Install the saddle valve according to the instructions printed on the bag.. Run ¼” copper tubing from the saddle valve to the humidifier.. Extend the tubing up through the port in the bottom of the humidifier and connect it to the fill valve.. Double wrench to prevent leaking and damage to valve..
