Routine Maintenance Cartridge Change-out Instructions (Pre/ Post Filter and RO Membrane Cartridge)
Read entire manual. Failure to follow all guide and rules could cause personal injury or property damage.
•
Check with your local public works department for plumbing codes. You must follow their guidelines as you install the water fi ltration system.
•
Your water fi ltration system will withstand up to 125 pounds per square inch (psi) water pressure. If your water supply pressure is higher than
80 psi, install a pressure reducing valve before installing the water fi ltration system.
To reduce the risk associated with choking:
•
DO NOT allow children under 3 years of age to have access to small parts during the installation of this product.
To reduce the risk associated with the ingestion of contaminants:
•
DO NOT use with water that is microbiologicaly unsafe or of unknown quality without adequate disinfection before or after the system. Systems certifi ed
for cyst reduction may be used on disinfected water that may contain fi lterable cysts.
To reduce the risk associated with property damage due to water leakage or fl ooding:
•
Read and follow Use Instructions provided with the original system prior to use of this replacement cartridge.
•
Change the disposable fi lter cartridge at the recommended interval; the disposable fi lter cartridge MUST be replaced every 24 months or sooner.
•
Failure to replace the disposable fi lter cartridge at recommended intervals may lead to reduced fi lter performance and failure of the fi lter, causing
property damage from water leakage or fl ooding.
•
Protect from freezing, remove fi lter cartridge when temperatures are expected to drop below 33° F (4.4° C).
•
DO NOT install systems in areas where ambient temperatures may go above 110° F (43.3° C).
•
DO NOT install on hot water supply lines. The maximum operating water temperature of this fi lter system is 100°F (37.8°C).
•
DO NOT install if water pressure exceeds 125 psi (862 kPa). If your water pressure exceeds 80 psi (552 kPa), you must install a pressure limiting valve.
Contact a plumbing professional if you are uncertain how to check your water pressure.
The RO membrane cartridges have green labels and will only fi t into the head on the right side of the manifold (head has a green 3M label).
Shut-Off procedure:
RO membrane cartridge will need to be changed at least every twenty four (24) months. Pre and Post Filter cartridges must be replaced every six
(6) months.
1. Unplug system from the wall outlet, which will shutoff feedwater to RO system.
2. Open Pre-fi lter sample valve until fl ow stops and left pressure gauge reaches 0 psi to relieve pressure.
Pre-Filter and Post Filter Cartridge (blue label) Replacement:
1. Push and hold yellow tab to release cartridge locking mechanism while simultaneously rotating cartridge to the left.
2. Using both hands and holding the cartridge from the bottom, rotate the cartridge a quarter turn to the left and gently pull down.
NOTE: A small amount of water will drain from manifold as cartridge is removed.
3. Remove red sanitary cap from new cartridge. Ensure o-rings are seated into their grooves and lubricate with water. Install with a quarter turn to
the right until cartridge come to a complete stop. NOTE: Cartridges are keyed to fi t in proper location only.
RO Membrane Cartridge (green label) Replacement:
1. Remove the reject tubing and the elbow from the RO membrane cartridge. (See Figure 1).
2. Push and hold yellow tab to release RO membrane cartridge locking mechanism while simultaneously rotating RO membrane cartridge to the
left.
