The only maintenance required is periodic cleaning to remove solids accumulation in the Condensate Accumulator housing. Before 
cleaning, gas pressure to the trap must be blocked and internal pressure safely vented. Then the top cover [4] and the 2" bottom pipe 
cap [1] can be removed and all solids washed from the tank into a suitable drain or container. Replace the cap and cover, using a new 
cover gasket [3], if necessary. 
 
If the sight gage glass tube should be accidently broken, both valves should be closed to prevent escaping gas and/or condensate. 
The glass tube may then be replaced by following instructions in the installation section. 
 
Inspection of seal tightness should be done to ensure compliance with local air pollution control requirements as needed. When 
inspecting the sediment levels, gaskets and seals should also be checked. Please refer to handling instructions listed in the Installation 
section of this manual. Always keep records of maintenance performed. 
 
WARNING
If the unit must be removed from service for any reason, make sure that all pressure has been released before the flange fasteners are
loosened. Refer to your company procedures before venting the line pressure and when handling toxic or otherwise hazardous 
materials. 
 
The main valve body, gaskets and all other components are exposed to the process vapor. Observe all standard safety precautions as 
specified on Material Safety Data Sheets for the product[s] in the system while removing the unit and when repairing it. Take 
appropriate safety precautions regarding eye protection, respiration & skin contact. 
TESTING PROCEDURE
Whenever the Condensate Accumulator has been serviced or maintained, before being placed back into operation the unit shall be 
pressure tested to ensure that no leaks are present in the connections. This can be accomplished by plugging all openings in the unit. 
Connect a pressure regulated line to one of the open ports and pressurize the unit to 1.5 times the MAWP of the unit (as stamped on 
the original nameplate). Check all connectors with a soap and water solution to detect for leaks. 
 
TROUBLESHOOTING 
If there is excessive leakage, inspect the following : 
 
- Inspect flange surfaces (Be aware of nicks, scratches and flatness)
- Inspect gasket
 
In order to maintain a tight seal, components have to be clean and have a smooth surface at the contact areas.
