do so could result in poor performance and/or personal injury.
11. Backwash the filter. After back washing the filter, check and record the inlet
and outlet pressure gauge readings. The media should be back washed
whenever the pressure drop across the filter (the difference between the two
gauges) reaches approximately 10 psig over starting pressure.
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 represents a leak in
the pump suction piping, and 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, PEP CL filters should be inspected, cleaned and lubricated on a
regular basis. The required services and recommended frequency minimums for
each are summarized on in the Operation and Maintenance Schedule in this manual.
Cold Weather Operation
CL filters exposed to below freezing ambient temperatures require freeze protection.
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 limitations, supplementary heat must be supplied through the use of
electrical heat tape and insulation. The parts of the filter that must be heat traced
and insulated are: pre-strainer tank, pump, piping, valves, pressure switch tubing,
and filter vessel. The unit should be drained when shut down for any period of time.
Refer to the Seasonal Shutdown section of the manual for recommendations.
