What is the allowable time frame for FLUCELVAX Quadrivalent 2017-2018 Preservative-Free Suspension for Injection to be out of the refrigerator?

FLUCELVAX Quadrivalent 2017-2018 Preservative-Free Suspension for Injection by Seqirus product information only allows for storage in the refrigerator. In order to dispense the vaccine efficiently at our institution, we are placing the vaccines in our Automated Dispensing Cabinet (ADC). We want to know if anyone has conducted studies on the vaccines to determine how long the product can be at room temperature without losing it activity/potency. This time is to allow us to stock the product in our ADC. 

Thanks
