INSTALLATION RECEIVING & UNPACKING EQUIPMENT 1. Check packing slip to ensure ALL material has been delivered. 2. All material shortages are to be reported to Liebert within 48 hours from receipt of goods. Liebert assumes no responsibility for any material shortages beyond this period.
to clearances required for plumbing, electrical, and control entrances. The clearance dimensions shown in this manual are for reference only and are the minimum required for maintenance of the humidifier. Local and National Codes should be consulted prior to final location and installation of the humidifier.

5. Exercise extreme caution when installing in fiber glass or internally lined ducts. 6. High positive or negative static pressure ducts or plenums have special requirements. High positive static pressure ducts may require the unit to be fitted with a fill cup extension kit.
10. Any distributor longer than 3 feet (1 meter) should be supported at its end with a threaded rod through top or bottom of duct. See Figure #10. 11. It is recommended that single distributors are mounted near the bottom of the duct to ensure the steam is dispersed into the majority of the air flow.
5. ALWAYS supply and install a shut off valve in the water supply line dedicated to the humidifier to facilitate servicing. Use ½ "O D copper to within 4 feet of the humidifier. Reduce copper to 3/8" OD and connect to the factory-supplied 3/8" olive compression fitting under the humidifier.
3. Liebert steam supply hose or field-supplied piping should be sloped downwards from the steam distributors to the humidifier. Slope should be at least 2" in 12" to promote condensate runback. See Figure #18. If this slope is not possible, condensate must be removed before the distributor.
ACCESSORIES - FILL CUP EXTENSION KIT(S) 1. The SGH humidifier is an electrode humidifier. It produces steam at atmospheric pressure. Pressure head must develop to push steam through supply line and into air duct. 2. Combined resistance of duct positive static pressure and steam line resistance creates a small pressure head in steam cylinder.
impeding condensate flow when duct pressures are below atmosphere. 6. The condensate line can go to either of two large holes in the fill cup cover on top of humidifier.
information is relevant to all controls, factory supplied or otherwise. A, B and C (described below) are to be wired in series (only one path for current) across terminals 8 and 10 on the low voltage control terminal strip, or replaced with a jumper wire for constant operation (see Figure #27).
4. The modulation signal must increase from minimum toward maximum as sensed RH (actual RH) drops below desired RH (%RH setpoint). In response, humidifier ’ s steam output will increase from minimum toward maximum. When humidifier ’ s steam output (lbs/hr) matches humidification load (lbs/hr), modulation signal will stabilize.
satisfied and stops again. The resultant short-cycling is easily overcome. A manual capacity adjustment potentiometer ( “ pot ” ) is provided on the SGH main pc board for that purpose. It is marked “ CAPACITY ADJUST ” and is adjustable from 25 to 100% of rating.
