Product Regulator Check and Setting

The product regulator is factory set at 4.6 psig (31.7 kPa) and
should not require adjustment.
To check for proper adjustment of the product regulator, take the
following steps:
1. Set the unit's I/0 power switch to the "I" position.
2. Turn the flow meter adjustment knob counter-clockwise
until it reaches 5 LPM.
3. Allow the unit to run for ten minutes.
4. Install test pressure gauge to the outlet of the Companion 5
unit.
5. The outlet pressure should be 4.3-4.9 psig (29.6-33.8 kPa).
If the outlet pressure is not within this range, the product
regulator needs to be adjusted.
