NOTICE: Water side pressure rating is 450
psi for FPT fittings and 125 psi for field or
factory installed swivel fittings.
NOTICE: Do not overtighten the
connections.
Flexible hoses should be used between the unit and the
rigid system to avoid possible vibration. Ball valves
should be installed in the supply and return lines for unit
isolation and unit water flow balancing.
