Your Automatic Water Salesman will accept 250 inputs ($62.50), so in a practical sense, it will accept “any” amount.
This timer contains 2 sets of switches in one unit of 10 switches. To move the proper switches to the “ON” position, use a pointed object such as a retracted ballpoint pen. DO NOT USE A PENCIL. The switches turn “ON” to the right. Remember: 1 quarter = 1 input. $1.00 = 4 inputs. $20.00 = 80 inputs.
The top 7 switches (Time per Coin) determine the length of time the water will run for EACH COIN inserted. One second is minimum adjustment and accuracy. Determine the length of time you want the valve to be open. Turn ON the switches that add up to that amount of time.
At 50 psi, a 2” water line will flow approximately 2 gallons per second. This will vary with valve size, length of run, friction loss, etc. All examples are based on these parameters. Larger valves and/or higher pressure = less time. Lower pressure = more time.
with switches 64; 32; 16; 8; 4; 2 ON (126 seconds). All other switches OFF.
with switches 16; 8; 2 ON (26 seconds). All other switches OFF.
with switches 8; 4; and 1 ON (13 seconds). All other switches OFF.
The bottom 3 switches (Coins to Start) determine how many (inputs) must be counted before the machine starts. Normally this is 1. If a minimum sale is desired, up to 7 inputs ($1.75) can be programmed. Adding the switches together determines the amount. At least one switch MUST be turned on.
These settings can be readjusted at any time as your water rates go up or you wish to change the minimum sale. Over the years, we have found the average cost of water to be anywhere from $3.00 to $10.00 per 1000 gallons. Your city's water pressure and selling rates will determine the amount of time needed.
