Quartz Cap
Transformer
UV Lamp
9
Model 375 & 380
The UV Lamp should have an effective life span of about 14 months after which
time it should be replaced.
To replace the UV Lamp:
Unplug the UV Lamp Transformer and shut off the
water flow to the Filter. Unscrew the UV Lamp
Transformer from the Quartz Cap and carefully
lift the Lamp straight up out of the Quartz Sleeve.
Replace the Lamp, reassemble and
restart the filter as described above.
Note: The UV radiation may cause
discoloration to some of the plastic parts.
This is normal and will not effect the
performance of the filter.
9. To clean and/or replace filter media
Shut off the water flow to the Filter.
Lower the water level inside the filter by removing the safety cap and opening
the Drain Valve located at the base of the Filter Body.
A garden hose with a 3/4"connector can be attached to the outlet of the Drain
Valve.
Open the Filter by removing the gray Thread Ring and Filter Lid and remove
the filter material to be cleaned and/or replaced and treat the filter media as
instructed below.
Reassemble the filter making sure to wipe the O-ring with a clean cloth before
replacing the Filter Lid and restart as described above.
Model 375 & 380:
unplug the UV Lamp Transformer and shut off the water
flow to the filter.
Open the Filter by removing the gray Thread Ring and Filter Lid (with UV module
attached taking care to lift the lid straight up so as not to damage the Quartz
Sleeve.
Clean the Mechanical Filter Media as described below.
Rinse using a garden hose with a nozzle. To get the best results direct the strong
stream of water between cartridge pleats.
A build up of some organic matter on the outside of the Quartz Sleeve, Middle
Pipe and Base Plate may occur. When cleaning or replacing the filter cartridge
wipe these items with a damp cloth to remove the organic matter.
Reassemble the filter making sure to wipe the O-ring with a clean cloth before
replacing the Filter Lid and restart as described above.
Start-up settings - Model 354
For normal operation the valves should be set as follows:
Drain Valve - Closed
Outlet Valve - Open
Side Valve - Open
Top Valve - Closed
8. Maintenance
All Chemical or Mechanical canister filters will clog over time due to the
unavoidable build-up of particulate matter, therefore regular maintenance is
required. The filters should undergo regular maintenance when either the
pressure reading (models 317, 325, 340 and 375) increases to halfway between
the Starting Pressure and the Maximum Pressure, or when the flow rate drops
to approximately half of that when the filter was clean.
Model 354
Can be cleared of particulate matter periodically by back-washing the system.
This can be achieved without disassembling the filter.
Switch off the pump supplying water to the filter and connect a garden hose
to the gray Drain Valve. Reset the valves as follows:
Drain Valve - Open
Outlet Valve - Closed
Side Valve - Closed
Top Valve - Open
Switch on the pump, water will now
flow down through the Polybeads
and wash particulate to the drain.
When Back-Wash is complete,
return all of the valves to the normal
operation settings.
The rate of water flow should increase
after each Back-Washing. The frequency
of Back-Washing required will depend on
the system bio-load.
