Your Curtis G3 System is Factory Pre-Set and Ready to Go, Right from the Box.

Following are the Factory Settings for your Primo Cappuccino Beverage System:

• Tank Temperature = 190°F

• Flavor Controls= Set at 60%

• Dispensing Mode Set for Manual Dispensing
Generally there will never be a reason to change your G3 programming. However, should you need
to make slight adjustments to meet your dispensing needs, programming instructions are provided

later in this manual.

System Requirements:

• Water Source 20 – 90 PSI (Minimum Flow Rate of 1 GPM)

• Electrical: See electrical schematic on page 9.

SETUP STEPS

1. The unit should be level (left to right - front to back), on a secure surface.

2. Connect the water line to the water inlet tting on the rear of the unit. Water volume going to the
machine should be consistent. Use tubing sized sufciently to provide a minimum ow rate of

one gallon per minute.

NOTE: Some type of water ltration device must be used to maintain a trouble-free operation.
(In areas with extremely hard water, we suggest that a sedimentary and taste & odor lter be
installed.) This will prolong the life of your PCGT6 and enhance product quality.

NSF International requires the following water connection:

1. A quick disconnect or additional coiled tubing (at least 2x the depth of the unit) so that the machine

can be moved for cleaning underneath.

2. This equipment is to be installed with adequate backow protection to comply with applicable
federal, state and local codes..

3. Water pipe connections and xtures directly connected to a potable water supply shall be sized,
installed and maintained in accordance with federal, state, and local codes.

Anti-Tip Brackets

To reduce the risk of tipping of the unit when the front door is opened, the unit must be
secured to the counter by properly installed anti-tip brackets. Failure to install the anti-tip
brackets will allow the unit to tip over if excessive weight is placed on the front of the unit.
Serious injury might result from spilled hot liquids or from the unit itself.

Whenever the unit is ever moved to a different location, the anti-tip brackets must also be

moved and installed with the unit.

This kit consists of two brackets, four screws, and these instructions.

Installation Steps:

1. Install the unit in a location near a water source and a 120 volt electrical outlet.

2. The unit should be level (left to right - front to back), on a secure surface.

3. Water hook-up tubing should be sized to sufciently provide a minimum ow rate of one

gallon per minute.

4. Find the location of the brackets. Mark the screw hole locations 18 inches apart. If the
unit will be installed against a wall, mark the bracket locations to allow 1¼” of a gap
between the rear of the unit and the wall. One bracket is required, two are optional.

5. Drill pilot holes. Drill a ⅛” pilot hole where the screws fasten

the bracket to the counter top.

6. Mount the bracket onto the counter top.

a. Insert the two screws into the holes on the bracket and

secure the bracket fasten the bracket with the screws.

b. Because the unit has rubber feet in the front and gliding

feet in back the unit can be slid backwards easily. Lift

slightly on the front of the unit and slide it back into the
brackets.

c. Slide the unit back so that the stud of the glide leg is

inserted into the U shaped hook on the bracket.

7. The bracket kit is now installed and the unit can be placed into service.
