Page 16 Air ﬂ ow indication is required. Indication can be provided by a BAS input or air ﬂ ow switch wired to the DriSteem control cabinet. Wire the air ﬂ ow switch to the DriSteem control cabinet as shown in the diagram included with the unit.
Page 17 CONTROL OPTION #2 – ELECTRIC TEMPERATURE SWITCH ONLY; CONTINUOUS HEAT EXCHANGER OPERATION The DriSteem control cabinet is not provided. An electric modulating control valve is controlled by a 2-10 VDC/4-20 mA signal from a control system (BAS) or modulating humidistat. Optional air ﬂ ow switch, high limit humidistat are wired in series with 24 VAC control circuit of the modulating control valve.

Page 23: Sequence Of Operation
Important: If the steam valve and heat exchanger control is to be provided directly by a separate BAS controller (Control Option #4 without use of DriSteem control cabinet), inputs and valve output controls must be linked to a BAS controller and sequenced as described below.
Page 24 OPERATION Sequence of operation 3. Humidification demand is provided by a control signal to the DriSteem control cabinet. When the demand signal is sufficient, steam will flow to 1) the internal heat exchanger and 2) the modulating control valve that provides steam output based on demand.
Page 25 11. A float switch is located in the steam dispersion panel header, and wired to the DriSteem controller. The switch circuit will open if condensate (water) depth in the header rises 1/2” above the heat exchanger tube.
Page 26 TEMPERATURE SWITCH With control options #2 and #3, a 2-position (On-Off) shutoff control valve is not used (see Figure 4-2). The Ultra-sorb XV internal heat exchanger operates any time pressurized steam is available to the dispersion panel. Install the temperature switch downstream of the internal heat exchanger to prevent operation of the modulating control valve if steam is not ﬂ...
Page 27 OPERATION Sequence of operation CONTROL CABINET STATUS LED The control board within the control cabinet includes a large Status LED that indicates multiple control conditions (see Figure 18-1). The Status LED is always “blinking”. It will be easy to see that the board is powered and operating because, at a minimum, it is running the Status LED.

Page 29: Start-Up Checklist
OPERATION Start-up checklist 1. Ensure all component wiring and piping connections are complete as CAUTION shown in the wiring diagrams provided with the unit. 2. Create demand for humidification by providing a demand signal to control Remove clear poly ﬁ lm; do not remove white PVDF insulation.

• Ultra-sorb panels with 9" (225 mm) or 12" (300 mm) tube spacings have no measurable air pressure loss. • Use DriSteem’s DriCalc sizing and selection software to calculate your speciﬁ c air pressure loss. ULTRA-SORB MODEL XV INSTALLATION, OPERATION, AND MAINTENANCE MANUAL...
Page 31: Strainer, Traps, And Valves
MAINTENANCE Strainer, traps, and valves STRAINER Inspect at least twice during the ﬁ rst year. If fouled, inspect more frequently. STEAM TRAPS Verify that the steam traps are functioning properly at least twice a year. A blocked steam trap will be at room temperature. A “blowing” steam trap is hot and noisy, and the discharge pipe from it is hot for up to 30 feet (9 m).
Page 32: Dispersion Tubes And Heat Exchanger
MAINTENANCE Dispersion tubes and heat exchanger DISPERSION TUBES • If steam or condensate is evident at the sealing surface, replace the seal. • Inspect insulating material for dirt and smudges; gently clean with damp cloth and soapy water or diluted nontoxic, biodegradable cleaner/ degreaser.
