Troubleshooting Form
Note: Never connect refrigerant gauges during startup procedures. Conduct water-side analysis using P/T ports to determine
water flow and temperature difference. If water-side analysis shows poor performance, refrigerant troubleshooting may be
required. Connect refrigerant gauges as a last resort.
