HARDNESS TEST
- Water to be tested should be taken from a tap after the water softener
- Measure 10ml of water into plastic bottle supplied (approximately 1/3 full)
- Add one Yes/No tablet to sample water, replace cap and shake until tablet has completely dissolved. (NOTE: do not handle Yes/No tablet with fingers)
- The final colour to be obtained for soft water is green. (Note: The shade of green may vary.) If the colour turns red, the water is above 20 mg/l hardness, therefore another regeneration is recommended.
- Rinse plastic bottle after each test has been completed.
- When used as above, the tablets change the colour from green to red at a hardness of approximately 20ppm based on a sample volume of 10mls.
Other hardness test kits are available for more accurate testing eg.
Hardness Tablets
Directions: Take a 50ml sample of water in a screw capped bottle. Add one (1) tablet to sample, shake or crush to disintegrate. Repeat until last trace of reddish tinge disappears. The final colour is usually blue but with some water a greyish coloured end point is obtained.
Using 50ml sample –
Hardness ppm = (number of tablets x 40) – 20
LR (BW) Tablets
Directions : Take a 100ml sample of water in a screw capped bottle. Add one (1) tablet to sample, shake or crush to disintegrate. Repeat until last trace of reddish tinge disappears. The final colour is usually blue but with some water a greyish coloured end point is obtained.
Using 100ml sample –
Hardness ppm = (number tablets x 2) – 1
Contact IBC Water if further details are required.
WATER SOFTENER CALCULATIONS
To ascertain DAYS between regeneration periods the following data or estimations are required.
(Let N be the number of days to be calculated)
- Water Hardness in mg/l call ð H
- Water Softener Hardness Removal Capacity from Table 1 in grams call ð C
- Daily Water Usage in litres call ð D
For household situations allow 250 litres per person per day.
CALCULATION
N = 1000 x CD x H
Select nearest lower whole number
If necessary consult your dealer or IBC Water Treatment for advice on setting up the softener.
XAMPLE
Household use for 2 people on 220 mg/l hard water using
Model SAST0922 at 1050 grams capacity.
N = 1000 x 1540 500 x 220 = 14 days
LOCATION & INSTALLATION
-
The softener requires an inlet water pressure between 140kPa (20psi) and 690kPa (100psi).
-
The softener should service all water lines in the house except the toilet and outside taps. The softener should be positioned on a level flat surface close to a drain or any other properly trapped waste outlet. The brass adaptors supplied are suitable for 20mm (3/4″) female fittings and the softener should be connected to the supply with raw water to the inlet connector and softened water lines to the outlet as indicated on the valve.
-
When facing the front of the control the inlet is to the right and the outlet is to the left.
-
The system pressure must be between 140 kPa and 690 kPa psi.
-
If the system pressure is greater than 690kPa psi a pressure reducing valve must be installed.
-
The unit must be installed in accordance with local codes.
-
Do not over tighten connections.
-
Drain line ID must be at least 12mm.
-
Teflon tape should be used when installing he drain fitting into the control valve.
-
The drain line must be free of kinks.
-
A safety float with an air check is installed.
-
Insure all connections are tight.
-
To initiate regeneration, turn the twist the timer knob clockwise to the 2 hour position.
Note : DO NOT use teflon tape when connecting the fitting kits to the control valve. -
There are two drain lines, one from the brine tank and one from the softener valve, these lines must have an air gap of at least 40mm or twice the pipe diameter at the drain entrance. The drain line from the brine tank is gravity fed and hence the drain is required to be below the outlet elbow on the tank.The drain line from the softener valve is under pressure during regeneration but forcorrect operation a maximum of 2.4m of 15NB pipe with no rises can be connected.
A manual Bypass should be installed.
TYPICAL INSTALLATION DIAGRAM
ENSURE THE INSTALLATION CONFORMS WITH ALL LOCAL PLUMBING CODES
A water conditioner should be installed on a level floor or surface as close as possible to a floor drain, laundry tub, or properly trapped plumbing outlet. Typical installations of conditioners and filters are shown in Figure B below:
Figure B : TYPICAL WATER SOFTENER and FILTER INSTALLATION
WHEN DISCHARGED AT END OF DRAIN, LINE IS AT: | DRAIN LINE RECOMMENDATIONS |
---|---|
1. Floor Level | a. Use any length of 1/2” pipe or larger. |
2. Control Level | a. For 30’ or less of drain line, use 1/2” pipe |
orlarger.b. For 30’ or more of drain line, use 3/4” pipe or larger.
CAUTION : Never connect the drain line into a drain, sewer line or drain tray without an air gap. Air gap should be located in drain line, above liquid level in brine tank.
BRINE TANK DRAIN
It is recommended that the brine tank have an overflow drain line. In the
absence of a safety brine valve or in the event of any malfunction of system,
the brine tank will be prevented from overfilling. Use a minimum of a 1/2” ID
tubing.
DO NOT CONNECT THIS DRAIN LINE TO THE CONDITIONER CONTROL DRAIN LINE.
PLACING THE SOFTENER IN SERVICE
- Turn the timer knob full clockwise from “off” to “off” ie. A time of 2 hours and open the inlet valve slightly. Slowly fill the resin tank. Air and water will be expelled out the drain line.
- Open the inlet valve fully, the brine tank should fill to the proper preset level and then the float will close off.
- Again turn the knob back clockwise to off (ie. 2-hours. position). Water should be drawn from the brine tank and pass out the drain. Allow to flow at the drain until any colour, objectionable taste and odours are absent and then return to anti-clockwise to offposition.
- The unit is now operational. Open the outlet valve and ensure the bypass valve is closed. Run the nearest cold water tap for a least 15 minutes to ensure the resin bed is flushed.
BRINE TANK
- Place at least 25kg of a coarse refined grade of salt (Water Softener Salt) in the brine tank and always maintain dry salt above the water level. The tank can hold up to 50kg of coarse salt.
- Periodically it will be necessary to allow the salt to “run-out” and clean out the brine tank of accumulated silt and insoluble material.
REGENERATION
Always regenerate the unit before the softener is completely exhausted. Should complete exhaustion occur, two or possibly three regenerations, each spaced four (4) hours apart, will be needed to restore the resin. To regenerate the softener, turn the timer knob clockwise a full turn ie. off to off (do not exert undue pressure) and release. The unit will then automatically regenerate and return to service.
During regeneration raw (hard) water is bypassed to service so it is advisable to regenerate the unit when water is not needed.
Water Conditioning Control System Installation, Operating and Maintenance Manual
Cycle Flow Diagrams
The service cycle position directs untreated water to flow down through the resin bed in the mineral tank and up through the riser tube. The water is conditioned when passing through the resin.
The slow rinse cycle position directs a slow flow of water down through the riser tube and up through the resin bed to drain. This slow flow of water pushes the brine solution through the resin bed.
In brine draw, concentrated salt brine is drawn from the brine tank and directed to flow down through the riser tube and up through the resin bed to the drain. Brine is drawn until the air check in the brine tank closes.
NOTE: THIS CONTROL VALVE FUNCTIONS WITH A PRESSURISED BRINE LINE. THE USE OF A SAFETY FLOAT IN CONJUNCTION WITH THE AIR CHECK IS REQUIRE
