The installation, and initial start-up of your dishwasher must be performed by qualified
electricians, plumbers, and authorized service technicians trained in commercial dishwashers.
Defects and repairs caused by unauthorized installers will not be covered by the dishwasher
warranty.
The HRU heats cold water supplied to the dishwasher's built-in heat exchanger which
raises the incoming temperature to approximately 110°F/43°C. The preheated water is
plumbed to the final rinse water booster which ensures a minimum final rinse water
temperature of 180°F/82°C to sanitize the clean wares. The HRU significantly reduces
the energy required to heat water for the final rinse operations.
