Puretec Customer Service

Thank you for purchasing a Puretec CBH Series water filter housing. Your system is a proven performer manufactured from quality materials and components and will give years of ‘spring like’ water, free of impurities, if maintained and installed properly (refer installation requirements

Introduction

The Puretec Big Bertha is a high flow bag filter housing for commercial and industrial applications. This convertible filter housing is an economical solution for most industrial filtration applications. The strong and lightweight filter vessel is resistant to a wide range of chemicals and converts easily from filter bag usage to cartridge filters.

Installation Note: A water filter system/tap, like any product, has a limited life and may eventually fail. Also sometimes failure happens early due to unforeseen circumstances.
To avoid possible property damage, this product should be regularly examined for leakage and/or deterioration and replaced when necessary. A drain pan, plumbed to an appropriate drain or outfitted with a leak detector, should be used in those applications where any leakage could cause property damage, and/or the water supply should be turned off if no one is home/present.

Taking Care of Your System

The CBH50 is made of 100% polypropylene and can be damaged if handled roughly.
After transporting the CBH, check the unit for stress or cracks.

Preparing Your System

Puretec systems are designed to run economically for many years but this is dependent on the initial installation and periodical maintenance.

Please read all instructions carefully as failures caused by incorrect installation or operation are not covered by warranty.

On removing your CBH50 system from its carton you should check all the components to ensure all are present and have not been damaged in transportation. You should have:

CBH50 filter housing
Leg stand set with corrosion resistant fasteners
High quality PP filter basket
Adjustable filter bag lock

Remove all the packing materials prior to use.

As a responsible manufacturer we care about the environment. We urge you to follow the correct disposal procedure for your product and packaging materials. You must dispose of this product and its packaging according to local laws and regulations.

Installing Your System

Important Note: The system MUST be installed vertically, as shown in the diagram. DO NOT install the system horizontally as this could result in uneven pressure/ damage the system and will void the warranty.

Loosen the housing cap and remove all parts from inside the unit (see pg.4 for list of components) Assemble the legs to the sides of the filter and use the bolts provided to fasten the legs securely.

Note: The legs cannot withstand any extreme torque and should not be put under any pressure from surrounding components, plumbing or other fixtures.

Position the unit in a suitable area with a sturdy base. Use bolts (not provided) to fasten the unit to the base via the provided holes in the feet of the legs.

Remove the basket from the filter housing. The basket may need a gentle anti- clockwise twist to loosen it from the base of the housing. Wash the housing interior with warm soapy water then flush with clean warm water. Blow dry with compressed air. This will remove any dust or debris accumulated from transport. The housing should be washed in this manner regularly to maintain optimum filter performance.

Connect the inlet/outlet to the unit using the supplied flanges if required. The pressure of the pipeline should be less than PN6.3 or SDR26. Pipework should be supported to relieve strain from the unit. Use of union fittings is recommended to enable easy disconnection and removal of the unit for servicing.

Note: DO NOT use liquid sealants on the unit as it may cause de- atomization of the polypropylene. Puretec recommends the use of thread tape on the inlet and outlet.

A pressure relief valve should be installed upstream of the inlet to protect the unit from any pressure surge or pulsation.

Installation Note: A water filter system/tap, like any product, has a limited life and may eventually fail. Also sometimes failure happens early due to unforeseen circumstances.
To avoid possible property damage, this product should be regularly examined for leakage and/or deterioration and replaced when necessary. A drain pan, plumbed to an appropriate drain or outfitted with a leak detector, should be used in those applications where any leakage could cause property damage, and/or the water supply should be turned off if no one is home/present.

INSTALLATION MUST BE COMPLETED BY A LICENCED PLUMBER. FAULTY OPERATION DUE TO UNQUALIFIED PERSONS WILL RESULT IN VOIDED WARRANTY COVERAGE.

Installing the Filter Bag

Close inlet valve or turn off the water supply.
Purge water from the system by opening a downstream tap or outlet. Isolate unit from the water system if required.
Remove housing cap and seal.
Remove the adjustable filter lock.
Remove filter basket (gentle anti-clockwise twist may be required).
Check there is no debris in the housing.
Remove packaging from new filter bag and gently fold the bottom end into a C-shape.
Slide the filter bag into the basket making sure the rim of the bag is correctly aligned with the rim of the basket.
Carefully place the basket assembly back into the housing, making sure to push the assembly firmly into the base of the housing to ensure a good seal.
Put the adjustable filter lock back into position.
Place the seal back onto the rim of the housing. Lubricate the seal with a silicone based lubricant. If the seal is perished or torn, replace the seal before proceeding to the next step. Replacement Puretec seal CBH-OR
Put the cap back on the housing, taking care not to shear the seal.
Tighten the cap (DO NOT overtighten the cap).
Note: The seal is designed to expand and form a water-tight seal when under pressure from the inside. DO NOT over-tighten the cap as it may damage the seal and cause leakage of pressure failure.
Open outlet valve (if installed) or downstream tap.
Slowly open inlet valve.
Check unit for leaks (if leaks are detected, start the procedure from step 1).
Open inlet valve to full open position once pressure in system has become equal and stable.

Installation of CBH-V Pressure Gauge (optional accessory)

Remove gauge and valve from packaging.
Note the difference in threads on the valve.
Assemble the gauge to the valve.
Close inlet valve or turn off the water supply to the unit.

Differential Pressure

It is important to regularly check the pressure differential across the unit during
operation. Operating above the recommended pressure will affect the flow rate and reduce the efficiency. When the differential pressure exceeds 1.10kg/cm2 it is time to replace the bag filter.

If the pressure differential drops suddenly, cease operation and isolate the unit, purge the water from the unit and check the unit thoroughly for stress or fractures. Sudden pressure fluctuations can cause seal failure and/or filter rupture.

A lack of differential pressure indicates that no filtration is taking place. When filtration is taking place the inlet pressure should be slightly higher than the outlet pressure.
Differential pressure will gradually increase as the filters start to retain more debris. If a lack of differential pressure is detected, stop the system and check for seal leaks or housing ruptures.
