Puretec Customer Service
Thank you for purchasing a Puretec Bag Filter System. Your system is a patented, proven performer
manufactured from only quality materials and components and will give years of clean, fresh, invigorating
shower water free of impurities if maintained properly.
Caution: Do not use with water that is microbiologically unsafe or with water of unknown quality without
adequate disinfection before or after the system.
The system is designed for metropolitan supply water but can be used in other situations. For other types of
water supply please contact your local Puretec stockist.
The Puretec Bag Filter System cartridge needs replacing regularly to maintain optimum performance. This is
a simple procedure when following instructions. For cartridge replacements contact your stockist.
Precautions
Warning: For drinking water applications, do not use with water that is microbiologically unsafe or of
unknown quality without adequate disinfection before or after the system.
Caution: Filter must be protected against freezing (when used with aqueous solutions), which can cause
cracking of the lter and water leakage.
Caution: Because of the product’s limited service life and to prevent costly repairs or possible water
damage, we strongly recommend that the bottom of all plastic housings be replaced every ten years. If the
bottom of your housing has been in use for longer than this period, it should be replaced immediately. Date
the bottom of any new or replacement housing to indicate the next recommended replacement date.
Notes
•Make certain that installation complies with all state and local laws and regulations.
• Do not use wicking or sealer for tting connections into the cap of the lter. Thread seal tape is
recommended for this purpose.
• Do not install where system will be exposed to direct sunlight.
• Allow a minimum of 80 mm clearance under the lter or optional sump stand to facilitate lter
changes.
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 SHOULD BE COMPLETED BY QUALIFIED TRADESPEOPLE.
FAULTY OPERATION DUE TO UNQUALIFIED PERSONS WILL RESULT IN VOIDED
WARRANTY COVERAGE.

Installation
1. Before installing, verify that the materials of construction of the Puretec Bag Filter System are
compatible with the uid being ltered.
2. The location of the lter should include the following considerations:
(1) adequate space for ease of changing the lter bag,
(2) drainage or containment to collect drained or spilled liquid, and
(3) proper ventilation, if required.
3. When installing the system, include isolation valves for the lter and support for the lter
housing. Use caution when applying heat near the lter housing. It is best to weld or sweat all
ttings before assembly to the lter. The lter head may be mounted to the lter support using
5/16 inch x 1¼ inch long bolts. The bolt spacing is 3 inch on center and the bolt circle is 2-1/8
inch.
4. The lter must be installed in the vertical position with the inlet/outlet ports at the top. Flow
through the housing is inline. Note the inlet and outlet ports when connecting piping.
5. The lter housing is equipped with a ¼ inch NPT gauge part an the outlet for installation of a
pressure gauge (included) and a 3/8 inch NPT drain port at the base of the sump (3/8 inch NPT
ball valve supplied). The gauge or valve should be installed using thread seal tape as a thread
sealant.
Bag Selection
The Puretec Bag Filter Housing is designed for use with Puretec lter bags. Filter bags are available in 1, 5,
10, 25, 50, 100 and 200 micron. Polypropylene is the standard bag material but nylon is available upon
request.
Start-up
1. Open the inlet valve. It is recommended that the inlet valve be opened before the outlet valve to
prevent any backow.
2. Vent trapped air from the system before opening the outlet valve.
3. Open the outlet valve.

Bag Replacement
The pressure dierential across the bag will remain fairly constant until the bag is approximately 80%
blinded o. It is recommended that the bag be changed when the pressure dierential reaches 15 psi.
However, this gure can vary with the type of lter bag. The bag manufacturer’s data should be consulted to
determine the actual pressure drop for replacement.
Warning: Review all precautions specic to the handling of the uid being ltered before changing the
lter bag. A lter bag that has been used with a hazardous liquid may contain residual amounts of this
material and should be handled with the same safeguards that would be used in handling any hazardous
and/or toxic material i.e. gloves, respirators, protective eyewear, etc. Filter bags should be disposed of in
accordance with federate state or local laws and requirements. Failure to follow precautions may result in
injury.
1. Close isolation valves to the lter.
2. Drain sump (See Warning above).
Note: If bag has not been changed on a timely basis it may not drain. If necessary, the liquid
contents of the used bag can be poured into the replacement bag to be ltered.
3. Unscrew sump from cap. Sump will unscrew counterclockwise.
Caution: Support sump at base while unscrewing to prevent dropping and possibly damaging
the sump or drain valve.
4. Remove basket assembly from sump (See Warning above).
5. Remove bag from basket.
6. Remove 0-ring from groove in the sump and wipe groove and 0-ring clean. Re-lubricate 0-ring
with food grade silicone lubricant or similar. Insert 0-ring in place and press into groove.
Note: This step is important to ensure a proper housing seal. Make certain the 0-ring is seated
level in the groove.
7. Insert new bag into the basket. Form the bag to the contours of the basket making sure that the
bag extends fully to the bottom of the basket.
Note: Make sure the lter bag overlaps the bag collar to insure a proper seal when the lter
housing is closed.
8. Screw the sump onto the cap and hand-tighten securely. Do not over-tighten.

Troubleshooting
Leaks
1. Check the 0-ring for dirt, cuts, or swelling. Replace 0-ring if necessary.
2. Make sure housing is closed properly. Hand-tighten securely. Do not over-tighten.
3. Check all threaded connections and re-thread as needed.
4. Check to see if the lter bag is dirty and blinded over (see Warning under Bag Replacement). If
this is the case, replace bag according to instructions.
Poor Filtration Results
1. Check to make sure the lter bag is properly seated in the support basket (see Warning under
Bag Replacement). The bag should extend fully to the bottom of the basket and the top should
overlap the sealing collar.
2. Check for rips or tears in the lter bag.
