•
1. Typically, in applications involving commercial dishwashers, two or more
tankless water heaters are needed. Contact Rinnai Engineering / Applications
department at 1-800-621-9419 for proper sizing in all commercial dishwasher
applications. (Have the dishwasher model number available).
2. A circulating system is required in all commercial dishwasher applications to
ensure you have hot water available at the dishwasher when it calls for hot water.
Circulating systems are also required in tank water heater applications.
3. DO NOT use a tankless water heater as a booster heater for commercial
dishwashers. When using a tankless water heater in conjunction with a hot water
sanitizing type dishwasher a booster heater recommended by the dishwasher
manufacturer must be used.

Multiple Unit
MSA Controls Installation
Use MSA controls when banking multiple units on the same manifold system in
residential or commercial applications. The MSA controls will sequence or rotate
between units to p
prevent one unit from being
g a “work horse”. In addition,,
these controls ensure each unit is firing at the same rate during operation, and
it electronically balances the flow rate through each unit, eliminating the need
for balancing valves.
