Re-install the cleaned coalescing filter unit, support grating and retaining pieces.
If the coalescing filter unit is not properly installed, the Aquator will not work properly or efficiently.
Check to see that the coalescing filter unit is reinstalled properly. Improper installation may result
in damage to the Aquator and/or reduce its efficiency.
Attach the manway lid.
Refill the Aquator to at least half way by using clean water. (See SECTION 10 for instructions.)
OPTIONAL PROCESS FOR CLEANING THE AQUATOR
If it has been less than 12 months since last cleaning the Aquator and if only the bottom sludge has built
up and the effluent water is contaminant-free, the following procedure may be sufficient for proper
maintenance:
Vacuum out the sludge from silt chamber.
Recharge the Aquator by filling it to the invert level of the outlet pipe with clean water.
(See SECTION 10 in this manual.)
INSPECTING THE AQUATOR
Continue maintenance by performing the following inspections as usage and the site conditions require
Inspect and clean the GPT.
Inspect the inside of the Aquator looking for sand, trash, sludge and oil build-up.
Inspect effluent water for oils or other contaminants during or immediately after a heavy rainfall.

REMOVING AND CLEANING THE COALESCER
Keep spare coalescing filters covered or out of contact with ultraviolet light.
Ultraviolet light from sunshine may damage the coalescing filter if left exposed for extended
periods of time and may reduce the efficiency of the Aquator when installed.
Never enter the Aquator, the riser, the manway extension or any other enclosed space without
proper training and OSHA-approved equipment. Failure to follow this warning could result in
death or serious injury.
Remove the sludge from under the coalescing filter support grating in the coalescing chamber.
Remove the coalescing filter. Use normal water pressure, ensuring the dirty water runs back into the drainage
system leading to the Aquator.
