Replacing the Cartridge
Cartridge life is directly dependent on water conditions and the volume of water filtered. Replace the cartridge when taste and
odour returns. Replacement may be required more frequently if water has excessive taste/odour.
1. Close valve and open faucet to depressurize filter. Press vent button on top of head.
2. Turn sump 1/8th turn to left and lower to remove. Remove old cartridge and replace. Replace sump and turn 1/8th turn to
right fully to stop (lock position).
3. Open valve and allow water to run until clear. Close faucet.
Maintenance / Precautions
Caution:
If your unit is not used in winter, or will be subject to freezing temperatures, drain unit and remove cartridges from
sumps. Place cartridges in sink or on a paper towel to dry, which will occur in several days.
Note:
Lubricate Head O-ring (2502 at least once a year and when draining for winter. Use food grade silicone grease (i.e. Dow
111 Compound) or another non petroleum lubricant. Water conditions can be hard on rubber seals. Head O-ring replacement at
least every two years is recommended to minimize wear and tear and prevent leakage.
Caution:
Due to a limited product service life and to prevent costly repairs or possible water damage, we strongly recommend
that sumps (#520) be replaced every 5 years. If sumps of your filter unit have been used for more than this period, replace
immediately. Date the bottom of any new sump to indicate next replacement date.
Do Not
clean housing with organic solvents such as those found in sprays for cleaning products or insecticides as these may
cause cracking or crazing and lead to failure and leakage.
Protect
filter from direct sunlight. Not intended for outdoor use.
Troubleshooting Guide
Problem
Solution
1. Sump is difficult to remove
- Unit may still be under pressure. Close valve and
open faucet to relieve pressure. Press and hold vent button
on top of head
- Head O-ring may be stuck. To break the seal, push up on the
sump before turning to unlock.
2. Leak at Head O-ring
- O-ring may be dry or cracked due to age. Remove sump,
cartridge and O-ring. Lubricate O-ring with food grade
silicone (i.e. Dow 111 Compound) or non petroleum
lubricant and reinstall. If seal still leaks, replace it or call
Envirogard for advice.
3. Leak at Vent Button
- Vent O-ring is not seating properly or is dry or cracked. Press
vent button several times to re-seat. If still leaking, contact
Envirogard for vent O-ring replacement kit.
