Protecting from the rain:
Your HOTTAP unit has been designed to be used outdoors however to ensure the unit remains in pristine working condition we strongly urge you to make all possible attempts to shield the unit from the elements. The unit is splash-proof however prolonged exposure to rain may result in the degradation of the internal components. The easiest way to protect your unit is to pack it away after use or keep it undercover to shield it from the weather.
Protecting from freezing temperatures and frost:
One last note regarding very cold temperatures - if you are in an area at a time when the temperatures approach or drop below zero you must drain the unit of water to prevent the water from freezing inside the unit and causing damage. Simply detach both water quick fittings and let the water drain from the unit. This will ensure that even if the temperature drops below zero your unit will remain safe and ready for next use.
