C. Troubleshooting
Problem:
Diaphragm operated steam valve fails to open.
Cause
Less than 5 to 6 GPM water flow.
Blockage of water flow path through
unit
Blockage of water flow path outside
unit.
Damaged diaphragm.
* Do not rotate connector (Item 103, Figure 5) after assembling the diaphragm.
Problem:
Outlet water temperature is slow in responding to desired temperature.
Cause
Condensate in steam line.
