[EnergyPlus_Support] air flow limit

Dear all:

During the simulation this error came up, but I dont understand the 
purpose!

** Severe  ** Sizing: COIL:DX:COOLINGBYPASSFACTOREMPIRICAL "COIL 
SISTEMA UNDERFLOW": Rated air volume flow rate per watt of rated 
total cooling capacity is out of range. See Input-Output Reference 
Manual for valid range.
   ** Warning ** COIL:DX:COOLINGBYPASSFACTOREMPIRICAL "COIL SISTEMA 
UNDERFLOW" - Air volume flow rate per watt of rated total cooling 
capacity is out of range at   7.120244238500870E-005 m3/s/w.
   **   ~~~   **  ...VolumeFlowperRatedTotCap=7.120E-005 Occurrence 
info=SUMMER DESIGN DAY IN TITLE, 07/21 01:00 - 02:00
   **   ~~~   ** Expected range for VolumeFlowperRatedTotalCapacity=
[  3.356000000000000E-005--  6.713000000000000E-005]
   **   ~~~   ** Possible causes include inconsistent air flow rates 
in system components,
   **   ~~~   ** inconsistent supply air fan operation modes in coil 
and furnace/unitary objects,
   **   ~~~   ** or variable air volume [VAV] system using incorrect 
coil type.




 The air flow used in this simulation was took from the catalog, so 
I should not change it. I would like to know if there is any way to 
avoid this error without changing the flow rate, or if I keep the 
air flow rate, will this result in substancial errors? 

Thank you, Emanuel
