16 Spec Stopper R-407c Refrigerant –No added cost with Data Aire –Liebert charges about $

17 Spec Stopper R-407c Refrigerant –Environmentally friendly 17

18 Liebert Data Aire Non-Locking Disconnect $ 50 0 Dual Float Condensate Pump $ 60 0 Firestat $ 75 0 Crankcase Heaters $ Steam Generator $ Gauge Panels $ R-407C $ Total Increase in Cost $1,960 0 Specification Control = $$$ 18

19 19 Spec Stopper (Ceiling Units) Belt Drive Fans –Standard with Data Aire –Liebert cost about $575

20 20 Justification Belt Drive Fans –Generates higher external static pressure to overcome duct losses

21 21 Spec Stopper (for Liebert) 4 Analog Inputs –Standard with Liebert –Data Aire *Cost about $250 * Example only; refer to PSG for current price

22 22 Reason to Omit 4 Analog Inputs –Seldom, if ever used –Increases cost –Only provide information, perform no useful function
