HotMax Features: 

HotMax is designed for a flow rate of 0.5 gpm. An acceptable range is 0.4 – 0.6 gpm. Flow rates outside this 
range will negatively impact the outlet water temperature and the flow pattern from the dispenser. 

The temperature control knob adjust water temperature in increments of 5°F 

 

Turning the knob clockwise increases the set output water temperature 

 

Turning the knob counter clockwise decreases the set output water temperature 

 

You can set or adjust the temperature at any time between 140°F – 200°F (60°C – 99°C). The 
temperature can be changed to your desired setting.  

HotMax will fill an 8 oz cup or measurement cup in 7.5 to 8 seconds with near boiling hot water.  

 

DANGER

 Hotter water increases the potential for Hot Water SCALDS

 

CAUTION

 

Removing the cover while the unit is energized or hot exposes electrical shock and burn hazards, 

which can cause INJURY or DEATH. Adjustment should only be done by a licensed plumber or electrician.
