e. Consideration shall be given to the potential effect of prevailing winds and possible sources
of airborne contamination and potential for 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 4˚C (40˚F).
g. Piping and components shall be made of corrosive resistant materials such as brass, copper
or stainless steel.
D. Control Panel and Alarm Sensors
The control system is C.U.L. labeled. The control system provides automatic lead/lag sequencing and automatic alter-
nation of pumps based on first-on/first-off principle with provision for simultaneous operation if required. Automatic

e. Visible indicator of “power on” and “compressor running” for each compressor
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
