water in it so the solution is carried into the
conditioner.
2. Press the REGEN button.
Note:
The above instructions reflect standard
commercial practices. Local codes may require
different installation procedures.
Brine Line Connection
Install an appropriate fitting onto the 1/4-inch male
NPT connection on the air check, Figure 7, and install
a length of flexible tubing between the air check fitting
and the brine pick-up tube at the brine tank.
Note:
Make sure that all fittings and connections are
tight so that premature checking does not take place.
Premature checking occurs when the ball in the air
check falls to the bottom before all brine is drawn out
of the brine tank. Refer to the
Troubleshooting
section in this manual for additional information.
Brine Tank Overflow Line Connection
In the event of a malfunction, the tank overflow
connection directs overflow to the drain instead of
spilling on the floor where it could cause water
damage. Complete the following steps to connect the
overflow fitting to the brine tank:
1. Locate the fitting hole on the side of the brine
tank.
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.
Placing Conditioner into Operation
Initial Start-Up
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 operation:
1. Remove the rear valve cover by pulling back on
the tab located on the lower rear edge of the
cover. Next, lift the cover off the valve.
2. Grasp the camshaft and rotate COUNTER-
CLOCKWISE (As viewed from the front of the
control) until the indicator on the regeneration
cycle indicator points directly to the word
BACKWASH.
3.
Fill the mineral tank with water Turning the water
supply off and place 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.
4. 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.
5. 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.
Open the water supply valve slowly to the full open
position. Carefully rotate the camshaft COUNTER-
CLOCKWISE until the indicator on the regeneration
cycle 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 for more than
two minutes. Rotate the camshaft COUNTERCLOCK-
WISE 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
