White Glove Delivery - Available -

What is White Glove service?

Standard common carrier delivery options cover the cost of getting an item to your shipping address but our White Glove delivery service does that and more!

The White Glove agent will call to schedule a Call Before Delivery within a four hour window, which gives you the flexibility to work around your busy schedule and to prepare the space where your item will be placed. Upon delivery, trained professionals will unload your large item from the truck, bring it into the room of choice, unpack the item and remove all packaging debris from the premises.

Please note that White Glove delivery will typically add 5 - 7 business days to your order's transit, and only includes 30 minutes of on-site time. If on-site time beyond 30 minutes is required, you may be responsible for additional fees. While the agents will bring the items into the location of your choice, this service does not include set-up of the items being delivered, such as installation of casters, shelves, or other accessories. Small items will not be unpackaged individually; they will be set in place and debris and packaging material will not be removed.

How To Operate A Hatco Hot and Cold Drop In Well

How To Operate A Hatco Hot and Cold Drop In Well

The Hatco drop-in hot/cold well is easy to operate. Let us show you how! To operate in the hot mode, you must first install the water baffle with the probe designation mark and match it to the location on the water level probe in the unit. Then, install the pan platforms that support your food pans. The number of pan platforms is determined by the size of the well. The yellow drain level must be in the closed, or forward, position to operate in the hot mode. The drain position indicator light will confirm the drain is closed. Move the power switch to the right, or hot, position. The hot digital temperature controller will activate, and the current temperature of the unit will appear on the display. The auto-fill system will fill the well, and the water level probe will maintain the correct water level automatically. The active symbol will show that the hydro-heater is heating the well. The unit is preset to 192 degrees Fahrenheit, 89 degrees Celsius. Allow approximately 60 minutes for the unit to reach set point temperature. Check the hot digital temperature controller to see that the unit has reached the proper temperature. Then, load the well with pans containing your preheated food items. There are several important points that apply to both hot and cold operation. Always use a food pan. Do not place food directly into the well. Stir thick food items periodically for uniform heating or cooling. Amazing! The food choices looked so good, it vanished. We have to get ready for an express salad bar anyway in this same location. To shut down the hot mode, move the power switch to the center or off position. The hydro-heater and auto-fill will be deactivated. After every use, be sure the unit is fully drained and all food pans, water baffle, and pan platforms are removed, cleaned, and stored after each use. Follow both the daily cleaning and periodically the “Cleaning the Hydro-Heater” instructions in the installation and operating manual. For cold mode, the well should be cooled down, clean, dry, and empty of water baffle and pan platforms. We suggest approximately 60 minutes or more to transition between modes in this unit. Keep in mind, the cold mode only operates if the yellow drain level is in the open, or back, position. Install the drain pan support bars. Each well can hold a variety of combinations. Shown are two full size and three one third size food pans. During the initial cooling time, the well will chill quicker with empty food pans installed in the well. Move the power switch to the left, or cold, position. Current temperature will appear in the cold digital temperature controller. A 5 minute program delay acts as a safe guard when switching from hot to cold mode. This ensures that all possible hot water is drained and prevents unnecessary cooling. After 5 minutes, an active symbol will appear to show that the condensing unit is chilling the well. The unit is preset to a cold temperature of 32 degrees Fahrenheit, 0 degrees Celsius. Allow approximately 60 minutes for the unit to reach set point temperature. Once the digital controller shows the proper set point temperature, replace the empty pans with pans loaded with your pre-chilled food. MMM, tasty salad bar items at optimum serving temperatures. Incredible how quickly these items disappear. To shut down the cold mode, move the power switch to the center, or off, position. The cold digital controller and condensing unit will shut off. Follow both daily cleaning and periodically the “Cleaning the Condensing Unit” instructions in the installation and operating manual. Check the temperatures for food safeness on the Hatco website before changing the set points. The range for cold digital temperature controller is 10-50 degrees Fahrenheith, -12-10 degrees Celsius. The temperature range for the hot controller is 65-192 degrees Fahrenheit, 18-89 degrees Celsius. To change the set point, press and hold the set key until the display flashes the default of 32 degrees. We will show changing the cold mode here. To change the hot mode set point, follow the same procedure. Press the up or down key to increase or decrease the temperature. If no key is set within 60 seconds, the display will revert to the previous set point and current temperature will be shown. Set point changes should be made in 1-2 degree increments. Wait approximately 1 hour or more for any change before checking for the result. Press the key to lock in the new set point temperature. The display will show the current temperature of the unit. The installation and operating manual goes into more detail about installing, operating, cleaning, and other panel functions of Hatco’s hot/cold drop-in well.

Hatco CWB-S4 Details

Keep your most popular cold dishes chilled to the perfect serving temperature with the Hatco CWB-S4 four pan refrigerated slim drop-in cold food well! Thanks to the slim design, this unit accommodates full size food pans end-to-end rather than side-by-side, adding a few extra inches of precious space between buffet lines. This ensures that customers will have an easier time accessing your salad or cold condiment bar, even with sneeze guards present. Plus, the slim design still looks uniform with the rest of your Hatco drop-in food wells for a consistent look across any serving line.

This food well fits four full size food pans and features a 1/2 hp condensing unit that circulates R-404A refrigerant, so you can be sure your food stays safely cold throughout the day. The full-body insulation improves energy efficiency while retaining temperature, and you can easily maintain and fine-tune this unit with its sight glass, service valves, dryer, filter, and receiver. And, with a drop-in design, this unit can easily be installed into existing countertops, buffet lines, and other surfaces.

To prevent frost buildup, a programmable automatic defrost can be adjusted to your needs through the electronic controls. The condensing unit is field adjustable so you can fit the unit perfectly in your countertop, and thanks to the built-in 1" drain, clean-up takes a matter of moments. This unit requires a 120V electrical connection.
