The Archon washdown station is a complete, pre-engineered package including:
1. Manually operated valves for steam and water supply lines.
2. Diaphragm operated steam valve that opens when 5 to 6 GPM (3 to 4 GPM for the WD2010L) of water
is flowing.
3. Flow orifice for three steam pressure ranges.
4. Integral steam and water line check valves to prevent back flow.
5. Positive steam safety shut-off.
6. Discharge liquid temperature gage.
7. Integral direct steam injection heater.
8. Integral wall mounting system.
9. Integral stainless steel hose rack.
10. Optional hose with swivel at each end & trigger-operated spray gun or lance.
Archon washdown stations are designed to heat the water by direct contact with steam, producing an efficient means
of cleanup for most industrial plants where cleaning applications are required.
B. Design Rating PSIG at Maximum and Minimum Operating Temperatures
To determine the maximum allowable working pressure for a specific temperature, the user must refer to Archon

A. Mounting
1. Although the washdown station can be oriented in any position, it is recommended to position the unit with the
steam and water inlet lines vertically. In this manner, the thermometer dial will be up-right, and the discharge
line will be pointing down.
2. Prior to mounting unit, remove the manually operated valves by loosening the union connection on the bottom
of each valve. Mount valves to inlet piping using Teflon tape or equivalent on all male pipe threads as shown in
Figure 3.
3. Mount the washdown station to the wall by drilling two (2) 5/8” diameter holes, minimum 1-1/2” deep, with
masonry drill 9 1/16” apart and on a horizontal plane. See Figure 2. After drilling holes, insert bolt anchors into
holes until they are flush with the wall.
4. Insert 3/8” diameter bolts through the holes in the mounting lugs and thread bolts into anchors making sure that
the pipe spacers are in place. See exploded view for proper sequence.
5. After mounting to wall, wrench-tighten union connections of each manually operated valve.
Figure 2
B. Effect of Related Piping and Precautions
1. The washdown station should be installed with piping and fittings that provide minimum resistance to flow.
Pipeline friction losses must always be a consideration when estimating washdown station performance.
2. It is recommended that provisions be made for pressure gage connections near the water inlet, and steam inlet
connections of the washdown station. If performance problems occur during operation, it may be necessary to
install pressure gages to identify the problem.
3. Steam line must be clean, insulated, and as short as possible to prevent condensation of steam and excessive
line friction losses.
4. Do not impose system-piping loads on washdown station. Unit is designed to be supported by the wall-
mounting bracket.
5. It is recommended that the steam line be provided with a steam trap and strainer. It is also recommended to
install an in-line water strainer in the water supply line to prevent occlusion of the line.
6. It is recommended to install check valves upstream of the washdown steam and water inlets to isolate the
washdown station from live steam and water lines all the time.

CAUTION
In addition to the check valves recommendation, the installation must comply with
Local, State and Federal regulations related to the industry where it is being
installed. This may include installing back flow preventers or vacuum breakers.
IV. OPERATION
A. Pre-operational Check
1. Check that all installation instructions have been completed.
2. Check that the manually operated steam valve is fully closed.
3. Check that the manually operated water valve is fully closed.
B. Operating
1. Turn water valve fully on. Keep it on throughout the entire operation process.
2. Depress trigger of spray gun to establish full flow of water.
3. Slowly and partially open the manually operated steam line valve to first check for leaks. If leaks are evident,
close valve, allow line to cool off, tighten connections, and repeat procedure until all leaks are stopped.
4. Slowly open the manually operated steam valve (no more than 1/ 2 turn) while depressing the trigger of the
spray gun, then adjust the steam valve slowly until the desired water outlet temperature is obtained.
Important: When adjusting outlet temperature of the washdown station,
make certain the discharge spray gun is pointing in a safe direction.
C. Diaphragm Performance
The diaphragm is always exposed to cold water only. The diaphragm is expected to perform perfectly for years, but
with the material being an elastomer, the life in terms of time and number of operations is uncertain. However, we
offer a full replacement one-year warranty on the Diaphragm performance.

B. Maintenance Procedure
1. Leaks at threaded connection should be corrected by taking the washdown station out of service and remaking
the connection using Teflon tape or equivalent on all male pipe threads as shown in Figure 3.
Figure 3
2. A washdown station, which leaks at an O-Ring or gasket, should be immediately corrected by tightening the
bolts at the connection or by taking the washdown station out of service and replacing the O-Ring or gasket.
3. Leaks at the diaphragm should be corrected by tightening the bolts at the diaphragm cap (8), or by taking the
unit out of service and replacing the diaphragm.
4. The stem packing in this unit is spring washer loaded and should seldom require adjusting, however, if a stem
packing leak does occur it can be stopped by tightening the stem packing gland (1/8 turn clockwise, at a time)
until the leak stops. If the leak persists, the stem packing should be replaced.
Signs of an internal steam valve stem leak or check valve leak is an indication of a worn or damaged stem or seat.

C. 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.
