CL44-VL

Overview

The Hobart CL44-VL is a CL-Series rack conveyor dishwasher. The available model-specific information identifies its incoming water requirements, drain connection, optional drain water tempering kit, and heat dissipation. The sources do not provide a complete CL44-VL specification sheet, so specifications for related CL44 models with other suffixes are not presented as specifications for this model.

The CL44-VL uses one cold-water supply. The manual lists the required incoming water temperature for a CL-VL with an 18 kW built-in booster as 55°F minimum and 80°F maximum. A drain water tempering kit is available as an accessory for CL-VL models.

Key Features

• Single cold-water supply, as specified for CL-VL models.
• 18 kW built-in booster configuration is listed in the incoming-water requirements for CL-VL.
• Drain connection can be made at either end of the drain body, with a plug at the unused end.
• Optional drain water tempering kit is available for CL-VL models.

• Incoming water temperature: 55°F minimum and 80°F maximum for a CL-VL with an 18 kW built-in booster.
• Drain connection: 2-inch NPT pipe through a trap; drain connection may be made at either end, with the opposite end plugged.
• Grease trap guidance: If required by code, the manual specifies a minimum flow capacity of 38 gallons per minute.
• Incoming water line: The manual calls for a minimum 1/2-inch inside diameter for the line supplying the machine.
• Heat dissipation: 6,100 BTU/hr latent and 3,100 BTU/hr sensible for CL44-VL.
• Optional accessory: Drain water tempering kit.

Installation & Requirements

Water supply

CL-VL models require one cold-water supply. For the CL-VL with an 18 kW built-in booster, the manual specifies an incoming water temperature from 55°F to 80°F. Use an incoming water line with a minimum inside diameter of 1/2 inch. The manual also warns that the water pressure regulator must have a relief bypass; using an unsuitable regulator may damage the machine.

Drain

The tank drain requires one connection to the floor drain and may be connected at either end of the drain body. A pipe plug is provided for the opposite end. Connect the drain through a trap to the sewer using 2-inch NPT pipe. If local code requires a grease trap, the manual specifies a minimum flow capacity of 38 gallons per minute. The drain water tempering kit is available as an accessory for CL-VL models; consult the instructions supplied with the kit for installation.

Operation

The manual’s preparation instructions begin with checking that the dishwasher is clean and that its parts are in place. The machine’s tank and wash-arm setup depends on its supplied configuration. Where a scrapper is fitted, the manual describes installing its standpipe, strainer pans, scrap basket, and upper and lower wash arms. For wash and rinse tanks, it describes installing the standpipes, strainer pan, scrap basket, and wash arms. Follow the instructions that match the machine’s configuration rather than assuming every listed component applies to every unit.

The troubleshooting table says that if the machine’s auto-timer has timed out, the operator can push START or insert a rack. If the machine is in Energy Saver Mode, press WASH on the HMI to resume. If a table limit switch is used and has tripped, check that condition as part of diagnosing a no-operation issue.

Cleaning & Maintenance

Before operation, the manual instructs operators to make sure the dishwasher is clean and all parts are in place. For a “dishes not clean” complaint, it identifies possible causes including a wash-arm nozzle obstruction, open wash-arm sliders, an obstruction at the pump, insufficient wash water, a drain obstruction, and worn or torn drain or manifold O-rings that allow wash water to drain away.

For a suspected pump obstruction, the manual directs operators to disconnect electrical power and follow lockout/tagout procedures. It warns that there may be multiple circuits and that all circuits must be disconnected. Drain the tank or tanks and check for an obstruction at the pump intake. The manual does not specify a maintenance interval in the available material.

Troubleshooting

No machine operation

The manual lists these possible causes: a blown fuse or tripped circuit breaker at the power supply; inspection doors that are not closed; a jammed conveyor; an auto-timer that has timed out; a tripped table limit switch, if one is used; or Energy Saver Mode. For the auto-timer, push START or insert a rack. To resume from Energy Saver Mode, press WASH on the HMI. Check that doors are closed and investigate a conveyor jam or power-supply issue as appropriate.

Dishes are not clean

Possible causes listed in the manual include insufficient wash water; a drain obstruction causing an open-drain condition; a worn or torn drain O-ring; open wash-arm sliders; a blocked wash-arm nozzle; a worn or torn manifold O-ring; pump pressure loss caused by an obstruction; or incorrect water temperature. The manual advises checking the relevant heat supply when temperature is incorrect: the circuit breaker for electric heat, the main steam valve, or the gas supply valve. For pump obstructions, follow the electrical isolation and lockout/tagout directions in the Cleaning & Maintenance section. Contact Hobart Service if the problem cannot be resolved safely or persists.

Applications

The CL44-VL is a rack conveyor dishwasher for commercial dishroom operations. The available sources do not specify a rack-per-hour rating or list particular dishware capacities for this model.
