Accessory Ultra Low Leak Vertical Economizer
Understand the signal words DANGER, WARNING, CAUTION,
and NOTE. These words are used with the safety-alert symbol.
DANGER identifies the most serious hazards which will result
in severe personal injury or death. WARNING signifies hazards
which could result in personal injury or death. CAUTION is used
to identify unsafe practices, which may result in minor personal
injury or product and property damage. NOTE is used to highlight
suggestions which will result in enhanced installation, reliability, or
operation.
Equipment Damage Hazard
Electrostatic discharge can short equipment circuitry. Ensure
that you are properly grounded before handling the unit.
Electrical Shock Hazard
Can cause severe injury, death or property damage. Disconnect
power supply before beginning wiring, or making wiring
connections, to prevent electrical shock or equipment damage.
GENERAL (When ordered with controls)
The system utilizes the latest technology available for integrating
the use of free cooling with mechanical cooling for packaged
rooftop units. The solid-state control system optimizes energy
consumption, zone comfort, and equipment cycling by operating
the compressors when the outdoor-air temperature is too warm,
integrating the compressor with outdoor air when free cooling
is available, and locking out the compressor when outdoor-air
temperature is too cold. Demand control ventilation is supported.
This can be used with single or multiple speed indoor fans.
The MicroMetl Ultra Low Leak Economizer utilizes gear-driven
technology with a direct-mount spring return actuator that will close
upon loss of power. When ordering with controls, The Ultra Low
Leak Economizer comes standard with a Mixed Air Sensor (Also
called The Supply Air Temperature Sensor), and the option of
Adjustable Dry Bulb, Enthalpy, Differential Adjustable Dry Bulb, and
Differential Enthalpy Sensors. CO2 and Smoke Detectors Sensor
are an additional field installed option.
