What is the purpose of a hot water booster heater?
The primary function of a booster heater is to provide 180°F (82°C) of hot water for the 
final sanitizing rinse in a commercial dishwasher.
What is the typical lead time for a booster heater NOT available in the Quick-Ship program?
The lead-time is generally 3-4 working days from date of order entry. Boosters in Quick-Ship are sent out the 
same day when orders are received by 12 p.m. Central Standard Time.
Are slide mount brackets available in lieu of legs on ALL water booster heaters, and is there 
an extra charge?
Slide mounting brackets are available only on Compact boosters because of weight and size
limitations. Imperial booster heaters must be mounted on legs. There is no charge for slide
mounting brackets when ordered in lieu of legs. When you order slide mounting brackets, you
will not receive legs with your booster.

What is a shock absorber and what is it used for?
A shock absorber is an accessory item that can be used in any water heater application. 
It reduces water hammer, or the “banging noise” that results from quick closing solenoid 
valves on the dishwasher.
With regard to PHASE, are Hatco electric booster heaters field convertible from single to 
three phase, or from three phase to single phase?
Only 6kW, 7kW or 9kW boosters, 208 or 240 volt, are field convertible from single to three 
phase or vice versa. All other models must be ordered specifically for single phase or 
three phase, and CANNOT be converted in the field.
Are there specific electric booster heaters that can be wired in single
phase?
208 and 240 volt boosters up to 18kW, and 480 volt in 4kW and 5kW Compact boosters, 
can be ordered in single phase.  While 24kW through 45kW boosters 240 volts and 24kW 
through 39kW 208 volts may be ordered in single phase, consultation with the factory and written confirmation is 
required, due to high amperage in these types of applications.
With regard to VOLTAGE, are Hatco electric booster heaters field convertible from 208 
to 240 or 480 volts or vice versa?
No. Hatco boosters are manufactured and UL approved specifically for 208, 240 or 480 volts, and are NOT field 
convertible.
