We are pleased you have chosen Crathco’s Whipped Hot Chocolate Dispenser for your hot chocolate service. You
have chosen the finest engineered, most functionally sound and easy to operate piece of equipment available. The
HC-2 is a manual push and hold dispense machine, producing 1 ounce of chocolate per second into any cup size. It
will accommodate bag-in-boxes, cans or hoppers of chocolate syrup.
Inside the carton you should find:
1) HC-2 Whipped Hot Chocolate Machine
2) Plastic chocolate hopper (optional)
3) Drip tray
4) Operation and Instruction Manual
The HC-2 Whipped Hot Chocolate Dispenser is supplied complete with a 6 foot, 120V A.C. 3 wire cord and NEMA
5-20 plug. Plugging the unit into a NEMA 5-20R outlet (20 AMP receptacle) is the only electrical service required.
Plumbing service requires a high temperature food grade water supply line. The water supply line is connected to a
1/4” male flare fitting in the rear of the unit. Installation should comply with the National Plumbing Code.

2.
Remove all packing material around the chocolate dispenser.
Place the hot chocolate dispenser upright on a leveled table at location intended for operation.
Place the drip tray on the front of the dispenser; using the 2 locating tabs on the sides of the tray.
An experienced plumber or equipment installer should connect the dispenser to a properly sized water line.
Water supply should be 0.75 GPM minimum, 30-75 PSI.
Installation should comply with the National Plumbing Code.
The water supply line connects to the male flare found on the rear of the unit, using a 1/4” female flare nut.
Copper or brass tubing or stainless steel braided teflon lined or similar high temperature food grade hose should
be used for the water line. Include extra length of water supply line to allow room to move the unit for cleaning.
Hot or cold water hookup can be used. Hot water will increase the production of the dispenser.
Be sure to flush the supply line before making the connection to dispenser.
A shut-off valve and union should be in the supply line near the dispenser.
Plug the hot chocolate dispenser into a 120V 20 AMP, NEMA 15-20 outlet. A 6 foot, 3 wire cord with NEMA 5-20
plug is required.
Fill the hot chocolate dispenser with water. With power and water supplies to the dispenser turned “On”, the
dispenser will automatically fill with water. The water tank holds 2 3/4 gallons. It takes approximately 5 minutes
to initially fill the water tank because of the auto refill system employed with this dispenser. When the water tank
is full of water, filling will stop and the water level will be maintained at this point.
The water in the tank will automatically heat up to dispensing temperature. A 30-40 minute initial heat-up time is
required when the dispenser is connected to 50 degree F water. If a hot water hookup is used, heat-up time will
be shorter.
Make sure the dispenser is filled with water and up to temperature.
Load a hot chocolate bag-in-box or fill hopper with chocolate syrup.
Caution: Do not use low temperature plastic tubing for water supply line.
