2. Insert the overflow fitting (not supplied) into the
tank and tighten with the plastic thumbnut and
gasket as illustrated in Figure 6.
3. Attache a length of 1/2in (1.3cm) tubing (not
supplied) to the fitting and run to the drain.
Note:
Don not elevate the overflow line higher than
3in (7.6cm) below the bottom of the overflow fitting.
Do not tie into the drain line of the control unit. The
overflow line must be a direct, separate line from the
overflow fitting to the drain, sewer or tube. Allow an
air gap as in the drain line connection, Figure 5.
Electrical Connection
Remove the twist tie from the power cord and extend
the cord to its full length. Make the power source
matches the electrical rating of the control. Be sure
the outlet you select is not controlled by a wall switch.
Placing Conditioner into Operation
After the water conditioning system is physically
installed, we recommend that the conditioner be
disinfected before it is used to treat potable water.
Refer to the
Disinfection of Water Conditioners
section in this manual. Complete the following steps
to place the conditioner into service.
1. Grasp the indicator knob on the timer (Figure 8)
and rotate it
counterclockwise
about 45° to the
back- wash position. You may find it helpful to
remove the rear cover (Figure 10) and rotate the
camshaft counterclockwise at the same time.
2. Fill the mineral tank with water by turning the
water supply off and placing the bypass valve(s)
into the "not in bypass" position. Open the water
supply valve very slowly to approximately the 1/4
open position.
Caution
If the water supply valve is opened too rapidly
or too far, resin may be lost. In the BACKWASH
position, you should hear air escaping slowly
from the drain line.
3. When all the air is purged from the tank (water
begins to flow steadily from the drain), slowly
open the main supply valve all the way. Allow the
water to run into the drain until the water appears
clear. Turn off the water supply and wait for about
five minutes to allow all trapped air to escape
from the tank.
4. Add water to the brine tank (initial fill). With a
bucket or hose, add approximately 4 gallons (15
litres) of water to the brine tank.
5. To start up the unit: make sure the water supply
valve is in the full open position. Carefully rotate
the indicator knob, Figure 8,
counterclockwise
until the indicator points directly to the centre of
the
REFILL
position and hold there until the air
check (Figure 7), fills with water and water flows
through the brine line into the brine tank. Do not
run the water into the brine tank for more than
one or two minutes.
Rotate the indicator knob
counterclockwise
until
the indicator points to the centre of the
BRINE/
SLOW RINSE
position.
Check the water is being drawn from the brine
tank. The water level in the brine tank will recede
very slowly. Observe the water level for at least
three minutes. If the water level does not recede,
if it goes up, or if air enters the air check sight
glass and the ball falls and seats, refer to the
Troubleshooting
section in this manual.
