Troubleshooting
Problem: Diaphragm
operated
steam valve fails to open.
Cause Cure
Less than 5 to 6 GPM water flow.
Make sure manually operated steam valve is turned off and raise
water pressure to achieve a minimum of 5 to 6 GPM (3 to 4 GPM
for the WD2010L) water flow.
Blockage of water flow path through
unit
Remove discharge hose and open water valve to check water
flow through unit.
Blockage of water flow path outside
unit.
Remove union valve connections to unit and open water valve to
check water flow.
Damaged diaphragm.
Follow Disassembly-Reassembly steps Section V., Paragraph D.
below and check for damage to diaphragm and replace it if
necessary.*
* Do not rotate connector (Item 103, Figure 5) after assembling the diaphragm.
Problem:
Outlet water temperature is slow in responding to desired temperature.
Cause Cure
Condensate in steam line.
Install or correct operation of steam trap in steam line near unit.
Problem:
Outlet water temperature is less than desired.
Cause Cure
Operating conditions do not meet
requirements to properly operate unit.
Check application, including consulting with Archon to determine
operating conditions
Water supply pressure too low with
respect to steam supply pressure.
Install water line pressure regulator to reduce water supply
pressure to 5 to 10 psi less than the steam supply pressure.
Problem:
The heated water spray leaving the spray gun shows bursts of steam (water vapor).
Cause Cure
Steam flow too high. Operating above
the recommended 190°F outlet water
temperature limit.
Throttle the steam flow or increase water flow to reduce the
discharge water temperature.
