SEQUENCE OF OPERATION

This sequence assumes employment of a single enthalpy economizer

using a two stage thermostat.

1. A call for cooling comes from room thermostat.

2. The enthalpy sensor determines if the atmospheric condi-

ons are conducive for using outside air for cooling. If YES,
the fresh air damper secon of the economizer begins to

open.

3. The EXH SET potenometer should be set such that when

the fresh air dampers are open approximately 70% of their
full open capacity, EXH1 is energized and the power exhaust

is powered to draw the relief air from the space. There is a

60 +/-30 second me delay built into the economizer control
before the fan motor actually energizes.

4. When the dampers modulate below the 70% open posion
due to a sased thermostat or atmospheric condions, the
power exhaust disengages immediately.

INSTALLATION

WITH ECONOMIZER

1. Open carton and inspect contents for shortages and dam­age.

2. Disconnect the power to the unit.

3. If the economizer is already fully installed, remove the

economizer hoods. If a new installaon, do not install the

economizer hood.

4. If installing in conjuncon with an economizer, install the

damper secon.

5. Remove the horizontal duct cover panel.

6. Slide the support legs through the guides. (Figure 1)

7. Feed the line voltage and low voltage wires through the
knockouts provided in the damper secon of the econo­mizer.

8. Aach the power exhaust hood over the barometric relief

opening. Extend the support legs and secure them using the

screws provided.

eed the line voltage leads to the control secon of the

F
package unit and aach them to T1 and T2 on the unit con-

tactor per the included wiring diagram.

10.

Aach the low voltage control leads to the Jade economizer

controller per the included wiring diagram using the side
connectors provided. (Figure 3)
