in the system. Oil any circulators requiring oil, following circulator manufacturer’s instructions.

Over-oiling will damage the circulator.

Use only S.A.E. 20 motor oil to lubricate the motor. Do not use universal household

oils. Motor could be damaged, resulting in possible severe property damage.

• Pressure: Verify cold pressure is approximately 5 psi. Fill if necessary.

• Water Chemistry: Verify heating system water pH of 8.5 to 11.0. Adjust as necessary. Add corrosion inhibitor

package to raise pH. Add scale inhibitor as testing indicates .

• Corrosion Inhibitor: Verify level per manufacturer’s instructions.

build up in the appliance, reducing heat transfer, overheating the metal. Leaking water may also

cause severe property damage.

Electrical shock hazard: Turn o power to the appliance before any service operation on the
