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 .
Supply water piping must be free of oils, lubricants, solder flux and other contaminants, which can cause foaming .
Follow local plumbing codes. An external backflow preventer may be needed .
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 .
DRAIN LINE
Attach the 7/8" I . D . drain tubing provided to the drain assembly at the bottom of the humidifier . Secure with the hose clamp provided . Do not over
tighten .
Make sure the drain line has a constant downward slope from the humidifier to the drain and is not kinked or blocked .
If floor drain is not available, use condensate pump (Part #4856) to route water to a suitable drain . Provide at least 16 inches for of drain line between
the Steam Humidifier and the condensate pump .
NOTE: The humidifier uses cold water to temper drain water to less than 140°F .
ELECTRICAL POWER WIRING & SHUT-OFF SWITCH
Only qualified electrical personnel should perform field wiring procedures. Improper wiring or contact with energized circuits can cause property
damage or severe personal injury.
All wiring must be installed in accordance with all governing electrical codes and with the wiring diagram provided inside the front panel .
• Do not loop power wiring .
• Do not use aluminum wire .
A safety grounding system that meets all governing electrical codes is required . The ground connection must be made with solid metal to metal
connections . Ground wire must be the same size as the power wiring .
With factory settings, the Steam Humidifier draws 11 . 5 amps +/- 10% . Use a minimum 20 amp dedicated circuit when installing to operate at 11 . 5
amps . The Steam Humidifier can be set to draw 16 . 0 amps +/- 10% by repositioning dip switch #1 on the control circuit board (see FIGURE 12) . When
set to 16 amps, use a minimum 25 amp dedicated circuit . For both applications, size wire according to local codes .
The Steam Humidifier is shipped from the factory wired for 240 VAC operation, but it can operate on 120, 208 or 240 VAC . If using 120V or 208V,
move the black/white jumper wire to the proper tab on the control circuit board. See FIGURE 13 .
WIRING INSTRUCTIONS
1. Install disconnect switch (not provided) between line power source and humidifier . Knock-outs for power wiring and low voltage control circuit
wiring are provided .
2. Connect power and ground wiring as shown in FIGURE 13 . Do not run high voltage power lines over internal circuit boards .
