NOTE: THE SANITIZER CHEMICAL FEEDER PUMP REQUIRES PRIMING WHEN THE MACHINE IS FIRST
INSTALLED OR WHEN AIR ENTERS THE SANITIZER AGENT LINE. SANITIZER PUMPS ARE NORMALLY LOCAT-
ED ON THE LOWER HALF OF THE MACHINE AND THE PRIME SWITCH WILL BE NEARBY.
NOTE: WATER MUST BE IN THE SUMP AND WASH TANK PRIOR TO DISPENSING CHEMICALS. SANITIZER IN
ORIGINAL CONCENTRATION IS CAUSTIC AND MAY CAUSE DAMAGE TO THE WASH TANK AND/OR SUMP WITH-
OUT DILUTION.
DISPENSER SET-UP:
The following dispenser settings should be used as a starting point:
Detergent Product Feed Detergent Rinse-Aid Sanitizer
Dishmachine Titration Water Pressure Feed Time Feed Time Feed Time
ES-2000XSP(PH) 10 drops * 20 PSI 4 seconds 4 seconds 6 seconds
ES-4000XSP 10 drops * 20 PSI 6 seconds 6 seconds 11 seconds
* -Titrate 1
NOTE: These settings are only STARTING POINTS.
This system will require adjustment to meet the conditions of water temperature and softness at each account. If the water tem-
perature is 160
°F or greater, it will require fewer seconds of feed time to get the same solid product usage.
EXAMPLE: If the feed water temperature is 170
°F the detergent and rinse aid feed times should be set to approximately
1 to 2 seconds. Please refer to the adjustment guidelines below as starting points to optimize the dispenser’s perfor-
mance.
WATER PRESSURE SET-UP:
1. Adjust the primary water pressure regulator so that the pressure gauge reads approximately 20 PSI flow pressure while the
detergent is feeding. If the account’s flow pressure is less than 20 PSI, turn the adjustment knob on the regulator clockwise
until the pressure gauge indicates the maximum flow available.
SANITIZER FEED SET-UP:
1. Set the sanitizer feed to six seconds for the ES-2000XSP(PH) or eleven seconds for the ES-4000XSP. Adjust the sanitizer
cam timer so that the sanitizer pump begins feeding immediately after the rinse cycle starts (when pump motor starts).
2. Prime the sanitizer pump using the prime switch.
3. Run a complete cycle on the dishmachine.
4. Titrate the rinse water using the chlorine titration test kit. Chlorine titration should be between 50 and 100 ppm. Adjust the
cam timer if the chlorine level is not correct.
