Page 14: Mounting In An Air Handling Unit
Recommended fasteners for mounting the Ultra-sorb to a metal support frame are 1/4–20 nuts and bolts or #12 self drilling and tapping screws. Due to the possible forces exerted on this application, DriSteem recommends fastener spacing not to exceed 6" (150 mm). On larger Ultra-sorb installations, vertical channels may be required on both the inlet and outlet ends of the humidifi... -

OPERATION Controls AIRFLOW PROVING SWITCH An air fl ow proving switch should be used to prevent the steam valve from opening if air is not moving in the duct. HIGH LIMIT HUMIDISTAT To prevent over saturation when duct air is cooler than 70 °F (21 °C), use a high limit (duct mounted) humidistat (Figure 10-1). -
