Air and Water Discharge Temperature
- 105
°
F to 125
°
F - Read on the “AUTO SENTRY W” control
panel.
Compressor Injection Water Inlet Temperature
- 90
°
F to 110
°
F - Check anywhere on the line from
the heat exchanger to the compressor inlet.
Water Injection Cooler Temperature Differential
(Air Cooled Heat Exchanger
- The water
temperature differential depends on the temperature of the air at the water injection cooler fan and the
cleanliness of the core faces. As ambient temperatures and core restrictions increase, the injection water
outlet temperature will increase. The injection water outlet temperature is approximately the same as the
package exhaust air temperature. The outlet temperature may be checked by installing a tee in the water
line between the separator/reservoir and the cooler.
Water Injection Cooler Pressure Differential (Air Cooled Heat
Exchanger)
- 5 to 7 psid - Check
injection water pressure differential in the same place as temperature. (See above.)
ELECTRICAL
WIRING
- Standard Units - The PureAir
compressor is factory wired for all starter to
motor and control connections for the voltage specified on the order. It is necessary only to connect the
unit starter to the correct power supply. The standard unit is supplied with an open drip-proof motor, a
NEMA 12 starter and control enclosure. See “Location” paragraph, page 5, for distance to nearest
obstruction on starter and control box sides of the unit.
WARNING
Electrical shock can cause injury or death. Open main disconnect switch, tag
and lockout before working on starter/control box.
GROUNDING
- Equipment must be grounded in accordance with Section 250 of the National Electrical
Code.
WARNING
Failure to properly ground the compressor package could result in controller
malfunction.
