Anti-Freeze Kit
Allows the protection of the appliance against water freezing inside of its pipes / heat exchanger.
The anti-freeze kit can be used where ambient temperatures are as low as -30°F/-35°C for short
periods of time.
Additional measures must be taken to the surrounding pipes connected to the unit in case it is
installed in a place where freezing temperatures are constant.
The heating elements in the Anti-Freeze kit are protected by ceramics and are clipped to the copper
pipes.
