  • Page 5 Seismic Bracket Air Deflector Install machine on an ice storage bin and ensure both are level to eliminate improper operation. Additionally, it is recommended to use the supplied seismic brackets to secure the ice machine and bin together. Proper Installation An air deflector is included with self-contained, air-cooled models IM-Series to prevent exhausted air from returning back to the condenser.
  • Page 6 Ensure the ICE-OFF-WASH switch is set to ‘ICE’. Ice will begin to drop into the ice storage bin after 10-15 minutes. The size of your ice storage bin, plus the ambient & water temps will Determine how long it will take to fill the bin.
  • Page 7 Locating the data plate. When taking a call for service, the first thing you want to do is obtain the model and serial number to the machine. This is not only important for warranty purposes but, in some cases, in determining which part to supply to the customer. Doing so will help eliminate any mistakes or handwriting illegibility down the road.
  • Page 8 Check for power. Does the machine have power? Look at the front cover and observe if the GREEN power light is on steady (not flashing). If the power light is off, check to see if circuit breaker has tripped or if the machine has become unplugged.
  • Page 9 Check for water. Does the machine have water? Look at the front cover and observe if the YELLOW “no water” light is on steady (not flashing). If the “no water” light is on, check to see if the water supply valve is open, that water trough inside the machine is NOT out of place, and that the water trough is empty (no water).
  • Page 10 Remove the water trough. Sometimes the water level sensor and water pump can become dislodged during transportation or installation and go unnoticed. Remove the water trough to expose the water level sensor and water pump. Pull the water level sensor down until the electrical connection is visible and make sure it’s securely connected.
  • Page 11 Check the ice thickness sensor. Part of the installation process is to check that the ice thickness sensor is properly adjusted. Too close to the evaporator and the customer will have hollow cubes (or worse) the machine won’t make ice at all. Too far from the evaporator and you’re freeze time will be too long and the customer will complain of “thick”...

  • Page 21 IM MODULAR SEQUENCE OF OPERATION INITIAL START-UP IM SERIES Move the ICE-OFF-CLEAN switch to the “ICE” position. Water inlet solenoid energizes and allows water trough to fill until water reaches the low-level sensor on the water sensor probe. Dump valve & water pump energize to discard the remaining water in the trough for 20 seconds.
  • Page 22 NORMAL CONTINUOUS SEQUENCE OF OPERATION DURING ICE MAKING MODE IM SERIES With water curtain closed, the dump valve and water valve are energized for 15 seconds. With brackish water emptied from the sump trough, the water pump and dump valve are de-energized.
  • Page 23 WASH CYCLE FOR ALL IM-SERIES MACHINES NOTE: If the machine is in the ‘ICE’ mode, first place the power switch in the ‘OFF’ position and wait for the machine to finish its current cycle and stop. With the power switch in the ‘OFF’ position, add the appropriate amount of ice machine cleaner or sanitizer to the water trough.
