5.9 Product Regulator Check and Setting
The product regulator is factory-set at 7 PSIG (48kPa) for the Elite, 20 PSIG (138 kPa) for
the Intensity
8 and 10 and should not require adjustment. To check for proper adjustment
of the product regulator, take the following steps:
Procedure A: NewLife Elite
1. Set the ON/OFF switch to the ON position.
2. Allow the unit to run for five minutes.
3. Turn the flowmeter adjustment knob counter-clockwise until it stops (wide
open).
4. The flowmeter ball centers itself on the 5.5 LPM line. If not, the product
regulator needs to be adjusted.
Procedure B: NewLife Intensity 8 and 10
1. Install outlet pressure test kit (TU131-1) to the outlet of the NewLife unit.
2.
Set the unit’s ON/OFF power switch to the ON position.
3. Allow the unit to run for five minutes.
4. Turn the flowmeter adjustment knob counter-clockwise until it stops (wide
open).
5. The outlet pressure should measure 20 PSIG for the Intensity 10. If the outlet
pressure is not at 20 PSIG the product regulator needs to be adjusted.
