• 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 possible forces exerted on this application, DriSteem recommends fastener spacing not to exceed 6" (150 mm). -
Page 14: Recommendations And Steam Inlets
INSTALLATION Recommendations and steam inlets RECOMMENDATIONS Integral heat exchanger Trapping • Ultra-sorb Model XV employs an integral heat exchanger to pressurize and lift • Low pressure, up to 15 psi (103 kPa) — fl oat and thermostatic (F&T) condensate up to 12" per psi (300 mm trap (Figures 12-1 and 12-2) per 6.9 kPa) of steam pressure. -
Page 15: Controls
Install the temperature switch (Figure 19-1) to prevent the header from fl ooding with condensate if the heat exchanger cools, such as if the condensate return main becomes fl ooded or the trap fails closed. DriSteem's temperature switch is a temperature-actuated make-break switch. The temperature at which it switches is adjustable and should be set at 210 °F (99 °C). -

Page 24: Maintenance
MAINTENANCE Strainer, traps, and valves STRAINER Inspect at least twice during the fi rst year. If fouled, inspect it more frequently. STEAM TRAPS At least twice a year verify that the steam traps are functioning properly. A blocked steam trap is room temperature. A “blowing” steam trap is hot and noisy, and the discharge pipe from it is hot for 30 feet (9 m). -

• If steam or condensate is evident at the sealing surface, replace the seal. • Inspect insulating material for tears; repair with Insulating Material Repair Kit (available from your local DriSteem representative) before dispersing steam or moving air through the air handler to prevent further damage. -
