Solutions:

If model is not equipped with a built-in air pressure gauge, remove pressure
gauge plug (solid plug) from end of filter cover and install a low pressure
gauge. Start heater and allow motor to reach full speed. With a flat head
screw driver, adjust the relief valve clockwise to increase pressure and counter
clockwise to decrease pressure. Set pump pressure to correct pressure for each
model. Stop heater. If accessory pressure gauge is being used, remove pres-
sure gauge. Install plug in end of filter cover (solid plug).
