RECHARGING TANK PROCEDURE
PROBLEMS :
•
When you turn on the spigot you get small water pressure and water flow.
•
When you turn on the spigot, only a quick burst of water comes out of the system, then it dies down to trickles.
•
When you turn on the spigot in the morning, you only can get less than a gallon of water.
If you have above problems, you should recharge the tank. The tank should have about 7 psi of air pressure when it is completely empty. The
storage tank has a water bladder inside, and it is surrounded by compressed air, so when you turn on the spigot, the compressed air would squeeze or
compress the water bladder to force the water out of the tank. When the tank is full the tank pressure can reach about 35 to 50 psi depending on your
feed water pressure, but to accurately recharge the storage tank, you should empty the tank then set the air pressure to 7 psi.
TOOLS NEEDED: An air compressor or air pump (like a bicycle tire air pump. An air pressure gauge that is able to read less than 10 psi.
Adjustable wrench or 9/11” wrench
STEPS:
1. Shut off the water supply to the RO system. Turn on the spigot to allow water to run until it stops (you can collect the water if you want)
2. Check to see if there is still water in the storage tank by lifting the tank. If the tank feels heavy, that means you need to recharge to tank, then
continue the following steps. If the tank feels light, that means you don’t need to recharge your storage tank at this time.
3. Locate the air valve on the side or on the bottom of the tank. It looks like the air valve on tires.
4. Use an air compressor or air pump to pump air into the tank. Keep the spigot on while pumping air, so that all water inside the tank can be
purged out. Don’t over charged it, just keep around 20 psi.
5.
After all water is been discharged, use an air pressure gauge to check the tank pressure.
6. The tank should have 7 psi of pressure when it’s empty. Add or purge air if necessary.
7. Turn the feed water valve back on, and turn off the spigot to allow refilling of the tank. It may take couple hours to refill the storage tank.
8. Finished
NOTE: If after few days of running the system, the problem comes back, then you may need to replace a new tank.
LIMITED ONE-YEAR WARRANTY
1. What your warranty covers:
WaterGeneral Reverse Osmosis+DI Systems are warranted to the original owner to be free of defects in material
and workmanship from the date of manufacture for two years as follows:
a. Manufacturer will, within one year of purchase, replace the defected parts (excluding filters) at no charge.
b. The replaceable filters are not warranted since the service life of replaceable filter varies with local water
conditions and thus not warranted.
2. Conditions of Warranty:
a. System must be maintained and serviced with the manufacturer original replacement parts and filters.
The performance of your drinking water system is directly related to the conditions of the water been
treated and the particular application in which it is used. Therefore, manufacturer’s liability is limited to
the cost of repair of the RO+DI system.
The manufacturer is not liable for incidental or
consequential damages of any kind. Systems must be installed and operated in accordance with
manufacture’s recommended procedures and guidelines.
3. What WaterGeneral Reverse Osmosis+DI Systems will not do:
a. Warranty is void if product failure or damage results from freezing, neglect, misapplication, fouling with
sediment or scale or failure to operate the system in accordance with the instructions contained in this
manual.
b. The following operating conditions must also be followed for this warranty to be valid
•
The hardness of the water cannot exceed 7 grains per gallon or 120 ppm.
•
No iron can be present in feed water. Or iron should be removed from feed water.
•
The pH of the water must not be lower than 3 or higher than 11
•
Feed water Total Dissolved solids TDS should not exceed 1000 ppm
•
Feed water temperature between 90 F and 45 F or (32C and 5 C)
4. Limitations and exclusions:
Manufacturer will not be responsible for any implied warranties, including those of merchantability and fitness
for a particular purpose. Manufacturer assumes no liability whatsoever for any incidental and consequential
damages, including loss of revenue, loss of time, travel expenses, inconvenience, and any damage caused by the
