4.3.e Operating Pressures and Water Flow Rates
CAUTION - Failure to heed the following may result in equipment damage.
Water flow exceeding maximum flow rate may damage titanium condenser; such
damage will not be covered under the equipment warranty.
Operating Pressure
A bypass valve is required when water flow may exceed maximum flow rates. The maximum static (or
operating pressure) is 50 pounds-per-square-inch (PSI).
Water Flow Rates
Design the plumbing system to maintain ideal flow through the heat pump under worst-case conditions
(i.e.: filter fouled to 10 PSI rise). These specifications relate to the heat pump only. Code-specified whole
system turnover rates must be satisfied. Contact AquaCal AutoPilot Technical Support for guidance
regarding testing for water flow rate.
