Precaution for Mono pool inflation and deflation

Low temperatures harden PVC material and make it more fragile. 
A new spa may have been stored or transported in cold conditions (below 4°C / 39°F) before unpacking. Please place the package indoors or in a warm area for at least 12 hours to allow the material to soften before use. 
The lower the temperature, the more air the spa tub requires and the longer inflation will take. 
To reduce inflation time, we recommend inflating the spa at temperatures above 15°C / 59°F. If the ambient temperature is below 0°C / 32°F, do not inflate the spa.
