filter inlet and outlet water lines to verify they are open. Make sure the pump is primed.
Start the pump and fill filter vessel. Wait for all the air in vessel to be released before
closing manual air relief valve.
7. Check the voltage and current of all leads on the pump motor. The current amp draw
should not exceed the nameplate rating.
8. Check the unit for any unusual noise or vibration and contact your local PEP
Representative if noise or vibration occurs.
9. Check the unit for any air or water leaks. All air leaks must be found and repaired.
Failure to do so could result in poor performance and/or personal injury.
10. Backwash the filter. After backwashing the filter, check the pressure gauge on top of
the filter tank and record the clean media operating pressure gauge. The media should be
backwashed whenever the pressure drop across the filter reaches 16 psi.
AFTER FIRST HOUR OF OPERATION
1. Open the air relief valve on top of the filter tank. Close the valve after the air has been
purged from the system. Excessive air release usually indicates an air leak, which must be
repaired. Air accumulation in the filter tank can result in an unsafe condition due to
excessive pressure within the tank.
2. Check the unit for any unusual noise or vibration and contact your local PEP
Representative if noise or vibration occurs.
3. Check unit for any air or water leaks.
OPERATION
During operation, the PEP Industrial Filters should be inspected, cleaned and lubricated on
a regular basis. The required services and recommended frequency (minimum) for each
are summarized in the table “Operation and Maintenance Schedule”.
COLD WEATHER OPERATION
PEP Industrial Water Filters that will be exposed to below freezing ambient temperatures
require protection to prevent freezing. Installation in a heated indoor space is the best
means of preventing the water from freezing in a filter. Where indoor installation is
impractical because of filter location or space limitation, supplementary heat must be
supplied through the use of electrical heater tape and insulation. The parts of the filter
that must be heat traced and insulated are: pre-strainer tank, pump, piping, valves,
