Filtaflo Customer ServicePuretec 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 filter 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 fitting connections into the cap of the filter. Teflon® tape is
recommended for this purpose.
• Do not install where system will be exposed to direct sunlight.
• Allow a minimum of 3 inches clearance under the filter or optional sump stand to facilitate
filter changes.

Installation
1. Before installing, verify that the materials of construction of the Puretec Bag Filter System
are compatible with the fluid being filtered.
2. The location of the filter should include the following considerations:
(1) adequate space for ease of changing the filter 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 filter and support for the filter
housing. Use caution when applying heat near the filter housing. It is best to weld or sweat
all fittings before assembly to the filter. The filter head may be mounted to the filter 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 filter 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 filter 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 Teflon® tape as a
thread sealant.
Bag Selection
The Puretec Bag Filter Housing is designed for use with Puretec filter 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 backflow.
2. Vent trapped air from the system before opening the outlet valve.
3. Open the outlet valve.

Bag Replacement
The pressure differential across the bag will remain fairly constant until the bag is approximately
80% blinded off. It is recommended that the bag be changed when the pressure differential
reaches 15 psi. However, this figure can vary with the type of filter bag. The bag manufacturer’s
data should be consulted to determine the actual pressure drop for replacement.
WARNING: Review all precautions specific to the handling of the fluid being filtered before
changing the filter bag. A filter 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 federat state or
local laws and requirements. Failure to follow precautions may result in injury.
l. Close isolation valves to the filter.
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 filtered.
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. Relubricate 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 filter bag overlaps the bag collar to insure a proper seal when the filter
housing is closed.
8. Screw the sump onto the cap and hand-tighten securely. Do not over-tighten.
