DETERGENT AND RINSE AID

If manually adding detergent in an LX18, LX18C, or LX18H at the beginning of each cycle, the machine must be programmed to the “True Fill and Dump” mode. This will ensure detergent is not dumped before filling with fresh, hot water. Contact your local Hobart Service Office to arrange for conversion.

Use only commercial grade detergents recommended by your chemical professional. Do not use detergents formulated for residential dishwashers.

On LX18 and LX30 models only, the detergent and rinse aid pump "ON" times are factory set. If adjustments are required, contact your local Hobart Service Office.

Place the detergent and rinse aid containers (which are obtained from an independent supplier) in a location where the delivery tubes will reach them.

Remove the detergent bottle cap and put the red delivery tube in the detergent container.

Remove the rinse aid bottle cap and place the blue delivery tube in the rinse aid container.

Be sure to push the delivery tube standpipes completely to the bottom of each container. Check to make sure there are no obstructions or kinks in the delivery tubes.

CHEMICAL SANITIZER (Models LX18C, LX30C, and LX40C Only)

CAUTION: Items such as pewter, aluminum, and silver will be attacked by sodium hypochlorite (bleach). Therefore, chemical sanitizing dishwashers should not be used to wash such items.

On models LX18C and LX30C only, the chemical sanitizer pump is factory set for use with 5.25% sodium hypochlorite solution. If 8.40% sodium hypochlorite solution is to be used, contact your local Hobart Service Office.

Place a one-gallon bottle of 5.25% or 8.40% sodium hypochlorite solution (bleach) in a suitable location no higher than 10 inches off the floor. Do not premix sanitizing solution with water or any other liquid.

WARNING: NEVER PREMIX A WETTING AGENT WITH THE SANITIZING SOLUTION. MIXING MAY CAUSE HAZARDOUS GAS TO FORM.

Remove the sanitizer bottle cap and place the white delivery tube in the sanitizer container. Be sure to push the delivery tube standpipe completely to the bottom of the container. Check to make sure there are no obstructions or kinks in the delivery tube.

Models LX18C and LX30C must be operated through four complete cycles (without dishes) to initially charge the sanitizer delivery system. On model LX40C, run the prime cycle (see Operator Programming, page 18).

Frequently check the clear portion of your chemical feed standpipe (at your sanitizer bottle) to make sure there is a sufficient chemical supply.
