Ice Water Bath Cleaning

with a vacuum cleaner or a soft bristle brush.

e. Clean the exterior surfaces of the compressor, agitator motor, fan motor, and fan blade with a damp cloth to wipe off the accumulated dust.

The water bath should be cleaned to obtain maximum cooling efficiency. It is recommended that the water bath be cleaned two to four times annually, depending upon local conditions and/or as required by state and local health departments.

A convenient time to do this is at the time the dispenser is being sanitized. To save time, the water bath can be drained while the dispenser is being sanitized.

a.Remove the cup rest and splash panel to access the water bath’s drain hose. Extend the drain hose to a suitable waste receptacle and allow the water bath to drain.

b.Remove the dispenser’s top bonnet by removing the two screws located on the top of the bonnet. While lifting the bonnet up and away from the dispenser, unplug the merchandiser electrical cord from the power strip located on the refrigeration deck.

c.In order to remove the refrigeration deck for the water bath and evaporator cleaning, remove the two screws that secure the deck to the cabinet structure. Unplug the refrigeration deck’s main power strip cord from the dispenser’s power cord. Disconnect the red, white and blue 12 pin plugs from the electrical box. Disconnect the key switch a by unplugging the white 2 pin plug at the transformer.

Note: It will be necessary to melt the ice bank to be able to pull the refrigeration deck up and away from the dispenser. Warm water may be used to accelerate the melting. In order to prevent ice bank control damage, do not direct the warm water stream on to the sensing bulb

of the ice bank control. Never use an ice pick or other instrument to remove ice from the evaporator. Such practice can result in a punctured refrigerant circuit or damage to the water bath tank.

d.Once the ice bank is sufficiently melted, lift the entire refrigeration deck up and away from the water bath by lifting the deck using it’s service handle strap.

e.Prepare 1 gallon (3.9 L) of cleaning and sanitizing solution (see “Sanitizing the Concentrate Lines & Valves”). Pour the cleaning and sanitizing solution into the water bath and clean the sides and bottom of the tank, the product coils, and associated brackets with a fiber brush.

f.Utilizing the cleaning and sanitizing solution in the water bath, the fiber brush, and a clean cloth soaked with sanitizing solution, clean the refrigeration deck’s evaporator coils, agitator motor shaft and blade, and the ice bank sensing bulb.

g.Drain the cleaning and sanitizing solution from the water bath and rinse/flush all the components with clean water.

h.Re-install the refrigeration deck into the water bath and secure with two screws.

i.Connect the refrigeration deck’s power strip to the dispenser’s power cord. Connect the red, white and blue 12 pin plugs to the electrical box. Connect the key switch to the transformer.

j.Fill the water bath with cool potable water until water begins to flow from the overflow tube.

k.Plug the merchandisers power cord into power strip located on the refrigeration deck and re-install the top bonnet. Secure the bonnet assembly with two screws.

l.Install the splash panel and cup rest and plug the dispenser’s power cord into the electrical outlet.
