530.25-N2 CAUTION. Never ouerate the unit without installingthe ho(xl o; moisture will be drawn into tht; unit. ECONOMIZER RAIN HOOD OPTION The outdoor and return air dampers, the sprirtg-returndamper actuator, the linkage, the enthalpy changeover control. the mixed air temperature control and the minlmurn posit]on potentiometer with manual auto switch are factory mounted as part of the economizer option.
5 It is recommended that the control band be set as shown: L 8°F for D SV300 7°F for D .SV360 6°F for D. SV480 The controller has a built in feature which provides a 4 minute off cycle and a 4 minute on cycle to prevent compressor rapid cycling. When power fails, the W7100 shuts off all stages of mechanical cooling. When power ~esumes,the economizer will first be modulated open, prowded enthalpy of the outside air is suitable.

5 - As the air quantity required by the VAV outlet boxes decreases, the static pressure in the duct system increases. Optional modulating dampers can be ordered with the urut to provide a constant static pressure in the duct system at all flow conditions. The optional air volume dampers are controlled by the accessory static pressure regulator that is located in the conditioned space.

530.25-N2 After the pre-start check list has been completed: CAUTION. If this method is used, the holes must be sealed with dot plugs (P/N 029-13880) or equivalent to prevent moisture from leaking into the unit. 1. Start the supply air blowers, L -) . Adjust the resistances in both the supply and the return duct systems to balance the air distribution throughout the conditioned space. The job specifications may require that this balancing be done by someone other than the equipment installer.

When they are removed and replaced with the connectors of the serviceanalyzer, the analyzer will override the dischargeair control. AHsystem functions such as heating, cooling, economizer, and night set-back can be slmulated.
530.25-N2 FIXED OUTDOOR Al R ADJUSTMENT To adjust the amount of fixed outdoor au, see Figure 18. Locate the amouni of outdoor air required and the return duct static on the chart to determine the position in which to set the blades, The blades can be adjusted by varying the position of the adjustment arm on the left side of the fixed outdoor air damper.
