< Back

Hobart dishwashers have been one of the standards in commercial kitchens. Whenever they need to be installed, owners like to call the professionals for help. If you’ve misplaced the instructions and can’t find them online, don’t worry! Below prep procedures and links to Hobart dishwasher installation manuals.

NOTE: This guide is only for authorized technicians. Equipment operators should contact a local Hobart service agent to conduct the tasks outlined below as well as additional repairs.

Pre-Installation Procedures

Before authorized technicians begin installing the dishwasher, Hobart recommends quickly checking and preparing the unit by doing the following:

Unpack the Unit

  • Check for damage – See if there is any damage that could’ve occurred during the shipping process. If there is damage, Hobart requires operators to contact them within 15 days of delivery.
  • Check electrical compatibility – Make sure the facility’s electrical service fits the specifications of the equipment. Check the machine data plate located near the control box.
  • Check for uninstalled items – Multiple parts are shipped loose in the package and are stored inside the unit. These typically include the chamber hole plug kit, curtains, overflow tube or standpipe and splash shields as well as instructions.

Verify Installation Codes

Confirm the installation codes for the dishwasher. The following are the national fuel and electrical codes as well as Canadian installation codes for CLe and C-Line Series models.

National Fuel Codes

  • CLe Series – ANSI Z223.1
  • C-Line Series – ANSIZ223.1

National Electrical Codes

  • CLe Series – ANSI / NFPA 70
  • C-Line Series – ANSI / NFPA 70

Canadian Installation Codes

  • CLe Series – CAN/CSA B149.1 and CSA C22.1
  • C-Line Series – CAN/CGA B149.2 and CSA C22.2 No. 1

Adjust the Height & Level

Once the machine is placed in the proper spot, make sure the dishwasher is leveled and at the correct height. This not only helps make operation as efficient as possible, but it also ensures that plumbing connections stay properly connected.

On CLe and C-Line Series machines, turn the adjustable feet to set the unit at the correct height and level. For LXe Series machines, start by placing a carpenter’s level diagonally on the rack tracks. Then, level the machine front to back and side to side by turning the adjustable feet. Once it’s at the proper height and level, cover the feet’s exposed threads with the black rubber tubing supplied by Hobart.

Water Requirements

Water quality is crucial because it reduces spotting on dishes, glasses and other wares. Confirm that the facility owner has contacted their local water supplier to get information on hardness and quality. Hobart recommends the following for best possible usage:

  • CLe Series requirements – Machine should operate at 3 grains of hardness per gallon or less. Chlorides shouldn’t exceed 30 parts per million.
  • C-Line Series requirements – Machine should operate at 4-6 grains of hardness per gallon. Chlorides shouldn’t exceed 50 parts per million.
  • LXe Series requirements – Machine should operate at 3 grains of hardness per gallon or less.

Any hardness above those requirements should be treated with water conditioner via a water softener or in-line treatment. Sediment, silica chlorides and other dissolved solids could require specific filtration or treatment.
