VL SERIES STEAMER - SERVICE PROCEDURES AND ADJUSTMENTS

B.With the boiler empty, check the voltage across terminals 9 & 10. Meter should read 300 to 350VAC. If voltage is correct proceed to step 3. If voltage reading is approximately 30VAC then the internal contactor is energized but the probes are scaled over and moist and/or have a damaged insulator giving a false reading. See “Water Level Probes“ listed below for inspecting and cleaning and “BOILER” for procedures on boiler inspection, clean-out and deliming. If you do not read any voltage, then contactor coil on the water level control is bad and the control should be replaced. Check for proper operation after replacement.

3.If water is in the boiler but is not being detected by the water level probes, the probes may need cleaned and/or boiler delimed. See “Water Level Probes“ listed below for inspecting and cleaning and “BOILER” for procedures on boiler inspection, clean-out and deliming.

4.Turn the power switch OFF and disconnect the lead wire from each probe. Note the location of the probes and the number of the wire connected to it.

A.Check the resistance between the probe terminal and boiler shell. An open circuit should be present when the boiler is empty. If resistance is present, remove and inspect the probes as outlined below under “Water Level Probes”. A resistance reading should only be measurable between the probes and boiler shell (ground) when the boiler is full of water.

NOTE: The actual resistance reading will depend on water quality and probe condition.

5.If after performing steps 1-4 and the control is not functioning properly, verify the water level controls operation as outlined in “WATER LEVEL CONTROLS” under “ELECTRICAL OPERATION”.

6.After checking the above items, if the low level cut off or differential water level control does not appear to be functioning as described, then replace the control and check for proper operation.

Water Level Probes

WARNING: DISCONNECT THE ELECTRICAL POWER TO THE MACHINE AT THE MAIN CIRCUIT BOX. PLACE A TAG ON THE CIRCUIT BOX INDICATING THE CIRCUIT IS BEING SERVICED.

1.Remove the cover over the water level probes and disconnect the lead wire from each probe. Note the location of each probe and the number of the wire connected to it. Remove each water level probe for examination.

2.If lime scale build up is evident on the probe, thoroughly clean it removing all deposits from the probe and insulator. Do not use any thing abrasive on the insulator; use a soft cloth.

3.Inspect the probes for a cracked or damaged insulator. If a probe appears to be damaged, replace it with a new one and proceed to step 5. If a probe does not appear to be damaged then proceed to step 4.

4.Check through the probe socket opening in the top of the canister assembly for the presence of water. Water must drain from the probe canister and if in doubt, pour water into the canister and observe that it drains quickly. If water fails to drain from the canister, remove the cover or canister assembly and clean.

5.Reverse procedure to install and check for proper operation.

CYCLING AND HIGH LIMIT

PRESSURE SWITCHES

(GAS AND ELECTRIC MODELS)

WARNING: THE FOLLOWING STEPS REQUIRE POWER TO BE APPLIED TO THE UNIT DURING THE TEST. USE EXTREME CAUTION AT ALL TIMES.

Remove the boiler control box cover as outlined under “CYCLING AND HIGH LIMIT PRESSURE SWITCHES (GAS AND ELECTRIC MODELS)” to access the two controls. The pressure switch on the right is the cycling or primary control; the one on the left is the high limit control. They are identical switches, differing only in their settings.

Turn the power ON and let the boiler come up to pressure. Close and seal one of the compartment doors, set a time past 5 minutes on the cooking timer, pull the steam control arm handle forward and turn the compartment power switch ON to exhaust pressure from the boiler. Observe boiler pressure gauge readings for several cycles and compare them with the pressure settings in the chart.

If the readings differ, adjust the pressure settings as described below.

VL2GPS, VL3GPS, VL3GSS, VL2GSS, VL2GAS specifications

Vulcan-Hart is well-known in the commercial cooking equipment industry, providing durable and efficient products that cater to the needs of restaurants and foodservice operations. Their line of griddles, namely the VL3GAS, VL3GPS, VL3GMS, VL2GAS, and VL2GPS, showcases their commitment to high-quality performance and innovative cooking technologies.

The Vulcan-Hart VL3GAS is a gas griddle, featuring a robust stainless steel construction that ensures longevity and resilience in a bustling kitchen environment. It offers a smooth, hot cooking surface that allows for optimal heat retention and distribution, ensuring that food cooks evenly. With a 3/4-inch thick steel plate, it provides excellent thermal conductivity, making it ideal for high-volume cooking. This model is designed with easy-to-use controls, which makes it convenient for chefs to operate.

The VL3GPS model is a gas-powered griddle that comes equipped with a patented grease management system, which aids in maintaining a cleaner cooking environment. This system helps to separate grease from food and minimizes flare-ups, enhancing safety during cooking. Additionally, the griddle features a temperature control that allows chefs to set precise cooking temperatures, ensuring consistent results.

Moving to the VL3GMS, this model introduces increased versatility with its combination of gas and optional electric features. It’s tailored for establishments that require flexibility in their cooking strategies. The VL3GMS is also designed with a spacious cooking surface, making it suitable for preparing a wide array of dishes simultaneously.

The VL2GAS is a two-burner gas griddle that is specifically tailored for smaller kitchen operations or those with limited space. Its compact design does not compromise on performance, still providing a durable cooking surface and reliable temperature control. This model is ideal for smaller cafes or food trucks where space is at a premium.

Lastly, the VL2GPS complements the VL2GAS with its grease management system. This enhances hygiene and ensures that cooking remains efficient and safe. Both VL2 models offer easy startup and shutdown procedures, making them user-friendly for chefs working in fast-paced environments.

Overall, the Vulcan-Hart VL series griddles combine quality construction, innovative technology, and efficient design. Whether it’s the three-burner or two-burner options, these griddles meet the demands of commercial kitchens, providing reliable cooking solutions that serve the dynamic needs of the foodservice industry.
