MR 150M–1050M SINGLE – MXIII CONTROLLER
OPERATION
12
START-UP INSTRUCTIONS - (cont’d)
10. Advance Unit to the Fast Rinse position by pressing and holding the EXTRA CYCLE button. The stager should ro-
tate to the STEP 3 (FAST RINSE) position. There will be a high ow of water to the drain. Allow the water to ow
to the drain until clear. During this time, the brine tank will ll with water until the oat closes the brine tank valve.
Check that all brine ttings are tight and that the water level in the brine tank is according to the unit specica-
tions.
11. Advance Unit to the service position by pressing and holding the EXTRA CYCLE button. The stager should rotate
to STEP 4 (SERVICE) position. There will be no ow of water to the drain.
12. Fill the brine tank with the proper amount and type of salt recommended for use with the system.
See RECOMMENDED TYPES OF SALT.
13. Close the manual by-pass valve and open all outlet valves fully. The system is now in service.
VOLUME REAMINING/BATCH CALCULATION
HOW TO CALCULATE SOFTENER’S TREATED WATER CAPACITY
“Batch size” is the term used for the amount of water passing through and being softened by the water softener be-
tween regenerations. This is a simple calculation provided two pieces of information are known:
• Size of the water softener in grains (i.e. MR-600 has 600,000 grains capacity per tank).
• Hardness of the raw water being treated by the water softener.
SAMPLE CALCULATION
Example:
MR-600-2 – Total capacity available is 600,000 grains. Water hardness is 20 grains per gallon.
BATCH SIZE
Batch size = Grain capacity of softener divided by grains per gallon of hardness
BATCH SIZE EQUATION:
Capacity of Softener (grains)
Batch Size = Hardness of Water (grains per gallon)
Capacity of Softener = 600,000 grains
Water Hardness = 20 grains per gallon
Unit is a model MR -600 softener
The hardness of the water was measured to be 20 grains per gallon
Using our equation take 600,000 ÷ 20 = 30,000 gallons.
For immediate regeneration type meter control the meter setting would be at 30,000 gallons. Commonly this value is
adjusted to 90 percent of the actual value (in this example 27,000 gallons) to assure not over-running the softener.
10% Safety factor - reserve capacity = 3,00 gallons.
30,000 gallons – 3,000 gallons = 27,000 gallons (batch size/volume remaining)
