Since the controller has a built in by-pass, the unit can be simply placed in-line with no valving
requirements by the installer.
It is highly recommended that an automatic drain trap be placed on the outlet side controller
header at the point designated as “Drain”. A trap on the inlet header can be used as well if
desired. Place the factory provided pressure gauges on the inlet and outlet headers at the
indicated points.
Prior to pressurizing the unit, close all valves. Once pressure has been applied, and prior to
applying power, slowly open valve V1. The control valve is normally opened. Slowly open valve
V2, allowing air to flow from supply to demand side without control. Valve V3 (by-pass) should
now be opened and remain opened during the power up and initial tuning stages.
Wiring (Stand-Alone with XMX-1V Controller):
The controller requires a low current 115VAC supply, 2 amps. min. and two shielded and twisted
pairs of wires to the control valve and pressure transmitter located on the Demand Expander
assembly. Terminals L1 and L2 have been designated as the power input terminals and by using
the provided conduit opening, place the 115 VAC hot wire on L1 and the neutral on L2. Close the
cabinet door and apply the power. The display should be illuminated.
