TrueSTEAM Humidification System Remote mount installation Use for mounting to a location other than the supply duct. Most operation problems are caused by improper hose installation. Always ensure an uphill flow when installing the remote hose, and avoid kinks, sharp turns, or low spots that could restrict the flow of steam into the injection nozzle or condensation back into the humidifier. If the remote hose cannot be installed with an upward pitch of 2 in./ft., a wetted drip tee must be installed. Failure to do so can result in back pressure on TrueSTEAM, which can lead to duct nozzle water spitting or leaking gasket. Remote hose must be supported to prevent sagging or low spots. When remote mounting, also follow these critical steps in sizing the proper TrueSTEAM: If the steam distribution tube is going into an unconditioned air space (e.g., attic), insulate the tube to ensure steam output efficiency: • Honeywell recommends self-seal pipe insulation for hot and cold water pipes. Insul-Tube 1-1/8 in. ID x 1/2 in. wall 25/50 Factory Mutual 062411, flame retardant added. The 6-gallon model (HM506) can be remotely mounted up to: • 5 feet without insulating the steam distribution tube • 15 feet if insulating the steam distribution tube The 9- and 12-gallon models (HM509 and HM512) can be remotely mount up to 20 feet with or without insulating the steam distribution tube. Ensure at least 2 in. per foot slope if installing the remote hose horizontally. Choose a location for TrueSTEAM and the 1 remote duct nozzle (see remote installs on pages 6-7). It should have access for: • Remote hose installation. Steam hose must be installed with 2 in./ft. pitch on a continuous uphill slope. • Drain. Allow a continuous downslope to the drain. • Cold water line. • Electrical circuit rated to your humidifier (see circuit ratings on page 10). Funnel or floor drain. Refer to governing codes for drain pipe size and maximum temperature requirements. Maximum 3 ft. 2 in./ft. uphill 6 in. 8 in. 1/2 in. minimum diameter M24896A Water in elbow  69-2036EFS-07
