e. Consideration shall be given to the potential effect of prevailing winds and possible sources of
airborne contamination and potential obstruction by accumulated snow.
f. Piping downstream of the compressor shall be routed in such a way that it is not subjected to a
temperature lower than 40˚F (4˚C).
g. Compressor intake piping shall be made of materials approved for vacuum piping compliant with
the latest NFPA 99 edition. In addition, the piping materials are assured to not contain contaminants
in the form of particulate matter, odor, or other gases.
D. Control Panel and Alarm Sensors
The control system is U.L. labeled. The control system provides automatic lead/lag sequencing and automatic alternation
of pumps based on first-on/first-off principle with provision for simultaneous operation if required. Automatic activation
of reserve unit, if required, will activate an audible alarm as well as a visual alarm on the display screen.

f. Two control transformers with secondary circuit breaker.
g. Manual / Off Auto selector switches (Each Compressor).
h. Transducer and RTD based control panel.
i. The RTD will digitally display the running temperature of each discharge port and shall be field
programmable to standard manufacturer’s operating parameter.
j. The calibration of the pressure transducer can be set so a non-standard transducer can be used.
2. Touch screen controls feature a minimum 5.7”screen. Screen displays and functions include:
a. WinCE 5.0 operating system.
