HM700A1000
Steam Lines and Condensate Return Instructions
The following instructions must be followed for installation of steam lines for the HM700. Failure to use recommended material
and exceeding maximum recommended length in Table 6, or failure to follow any other steam line installation instructions will
result in improper operation and could void the warranty.
Steam Output
Voltage lbs/hr (kg/hr)
110/120V 3.85 (1.75)
220/240V 7.7 (3.5)
* The use of steam line other than copper, stainless steel tube or Honeywell supplied steam line will void the warranty and may
adversely affect the operation of the humidifier.
* When using copper or stainless steel tubing (other than the supplied tubing), insulation is recommended due to high
temperature safety as well as reduced condensate.
To return condensate for HM700, insert copper tube (supplied with equipment) half way into the condensate opening of the fill cup
along with the spring clamp (supplied with equipment).
Insert the condensate hose into the condensate return hole at the top of the HM700, and over the copper tube. Fasten in place
with the spring clamp.

MAIN RULES FOR ATMOSPHERIC STEAM LINES
• Steam lines must not have any restrictions which could result in back pressure.
• Follow recommended materials, size and length, see tables.
• Install steam line in a vertical (upwards) fashion from the HM700 to the distribution nozzle. Consult Figures 12-14 for other
installation options.
• Insulate with 1.0 in. (2.5 cm) pipe insulation.
• Trap condensate (Use full size 'T' for Traps)
• Do not over tighten hose clamp at cylinder steam outlet. The maximum torque is 12 in-lbs.
• Support steam line so weight is not on cylinder.
• Condensate traps must be a minimum of 6 in. (15 cm) in height or duct static pressure +2 in. (5 cm), whichever is greater.
• Trapping by P-trap or pigtail. Support line as necessary to ensure it remains free of kinks.
