Temperature 15 C   20 C  27 C 
  60 F   68 F   75 F  

√ Store capsules away from direct sunlight (e.g. windows and skylights) as it will raise the surface temperature of a carton.

√ Store capsules away from hot water/air radiators, hot water pipes and steam pipes.

√ Store capsules on pallets off the ground.
