Troubleshooting (cont’d)
1.
Too high of a pumping rate during filling. The pumping rate should be
40 - 85 gpm ((150 LPM - 300 LPM) with a maximum line pressure of
85 psi.
2. Restriction in the vent piping. This can be caused by debris in the vent
piping and/or vent cap or a problem with the vent whistle. Contact your
oil service technician if the vent whistle is causing the problem.
3. The interstitial has water in it and the water has frozen at some point.
