SUPPly waTeR
Plumb the humidifier to cold, hard or softened water .
Do not use hot water because unheated supply water is used to cool water
draining from the humidifier.
Do not use demineralized or reverse osmosis water . For proper operation, supply water pressure must be between
25 psi and 120 psi . Hard or softened water may be used provided it has conductivity between 125 microS/cm and 1250 microS/cm . See
Table 2
.
Supply water piping must be free of oils, lubricants, solder flux and other contaminants, which can cause foaming .
Install the saddle valve according to the instructions printed on the bag . Run 1/4” copper tubing from the saddle valve to the humidifier . Connect
it to the fill valve . Double wrench to prevent leaking and damage to valve . Addition of a stainless steel braided water line can help reduce valve
noise .
note:
Adding an inline particulate filter can increase canister life in areas with high levels of suspended solids . DO NOT use filters that release
scale inhibitors, filters of this type can significantly decrease canister life .
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 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 .
MoUnT HUMIDIfIeR
Secure humidifier to sturdy wall using screws provided, or to sheet metal duct . Humidifier initially weighs 23 lbs with a full canister, but will
increase in weight over time due to the precipitation of minerals inside the canister . Make sure mounting system will support weight . If mounting
to stud frame wall, install two spanner boards to studs and fasten humidifier to spanner boards . Make sure humidifier is mounted plumb .
InSTall STeaM DISPeRSIon TUbe/fan PaCk
Make sure steam dispersion tube/Fan Pack is mounted higher than the humidifier so that condensation that forms in the steam hose runs back
into the canister . If the dispersion tube/Fan Pack 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 (Part #4028) must be installed as shown in
figure 9
.
Drill a 1-1/4” diameter hole in a vertical surface of the duct at the location chosen for the dispersion tube . Position the dispersion tube so it is
angled up, regardless of airflow direction . UP is stamped on the mounting bracket to aid in proper installation . Secure with four sheet metal
screws provided .
InSTallaTIon InSTRUCTIonS
(ConTInUeD)
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 insulation rated for 212°F or higher to reduce
steam loss . See
Table 4
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, reduced steam production and water sputtering into the duct . When using pipe, remove all traces of residual materials used to
connect the pipe to prevent foaming .
Verify that the O-ring is in place in the groove in the drain assembly . Dampen the O-ring with water (DO NOT use oil, grease,or any lubricant
besides water), then reinsert the canister with the caution label positioned toward the front of the unit .
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 . Support the steam hose in multiple locations over its span to prevent sagging .
Attach and fully seat the electrode conductors (interchangeable) and the high water level sensor wire to the top of the canister .
