Sanitize the Storage Tank
The two options outlined below are the most convenient ways to sanitize the storage tank of your drinking water
appliance. Other methods may be used but require more complex procedures and apparatus typically used by
a professional Hague service technician.
Option 1
1.
Close the feed water valve and open the RO spigot to drain any water from the storage tank. The tank
should be light when picked up. If the tank is heavy, leave the spigot open; use a tire pump and pump
air into the tank to displace the water. When the tank is drained, use a low-pressure tire gauge to adjust
the air charge between 5 and 7 psig (34 and 48 kPa).
2.
Close the RO spigot and close the valve on top of the storage tank 1/4 turn clockwise. (See Figure 2.)
3.
Remove the red locking clip and disconnect the yellow tubing from the tank valve.
4.
Place the tank in the sink with the valve port pointed away from you and open the valve 1/4 turn
counterclockwise to rid the tank of any water not previously drained.
5.
Add 1/2 teaspoon (3 mL) of chlorine bleach (5.25% - unscented) to the port of the tank valve.
6.
Close the tank valve. Put the tank back in place and reinsert the yellow tube and red locking clip.
7.
Open the feed water valve to pressurize the appliance and verify flow to the drain.
8.
Open the tank valve and let the appliance run for two to five hours to fill the tank. Lift the spigot handle
to empty the tank and allow the appliance to refill. The water is now ready for use.
Option 2
Follow steps 1 and 2 as outlined above, then proceed as follows.
1.
Remove the Pre-Filter housing and discard the spent cartridge. Wash out the housing with warm water
and soap using a bottlebrush and then rinse thoroughly with clear water to flush away any soap
residue.
2.
Insert the new cartridge for the specified model.
Caution: Do not touch the filter with your bare hands. Peel the wrapper and use as a sleeve to prevent
contamination. Wearing clean latex gloves can help prevent hand contact.
3.
Pour 1 teaspoon (5 mL) of chlorine bleach directly down the center of the Pre-Filter cartridge so it will
collect in the small cuplike centering device in the bottom of the housing. Keep the housing upright
when attaching to prevent spilling.
4.
Remove the 1/4-inch red locking clip from the elbow on the “OUT” port of the pre-filter cap,
(See Figure 17, Item 2). Disconnect the red tube.
5.
Remove the 1/4-inch red locking clip from the 3/8-inch x 3/8-inch x 1/4-inch reducing tee,
(See Figure 17, Item 7) and disconnect the 1/4-inch blue tube from the 1/4-inch branch of the reducing
tee. Use a suitable length of 1/4-inch polyethylene tubing and connect to the elbow and tee
connections.
6.
Open the feed water valve and the tank valve and allow the sanitizing solution to flow to the tank for
two to three minutes for the standard 4.4-gallon tank (11.7 L).
7.
Close the tank valve and the feed water valve. Lift up on the spigot handle to depressurize the tank line
and let the water flow until it stops and then close the spigot handle.
8.
Remove the by-pass tubing and reconnect the red and blue tubes as well as the locking clips.
9.
Open the feed water valve and the tank valve. Drain the tank after twenty to thirty minutes and allow
the appliance to refill. The water is now ready for use.
