INITIAL SET-UP

CAUTION: The dispenser is very heavy! Use care when lifting or moving it. Use at least two people to lift or move the

dispenser. Place dispenser on a sturdy counter or shelf able to support at least 125 lbs. (57 kg).

The dispenser is designed for indoor use only, in ambient temperatures ranging from 50°F to 90°F (10°C to 32°C). Avoid locating the machine where it will be subject to direct sunlight or exposed to other external heat sources. Allow a minimum clearance of 6” at the back and top of the dispenser, and a minimum of 4” at either side of the dispenser for proper air circulation. Leave some space so the dispenser can be moved for cleaning.

ELECTRICAL REQUIREMENTS

CAUTION: The dispenser must be disconnected from the power source until speciﬁed in Electrical Hook-Up.

The 120V rated dispensers have an attached cord set and require a 2-wire, grounded, individual branch circuit rated 120 volts ac, 15 amp, single phase, 60Hz. The mating connector must be a NEMA 5-15R. Refer to the data plate for exact electrical requirements.

ELECTRICAL HOOK-UP CAUTION: Improper electrical installation will damage electronic components.

1. An electrician must provide electrical service as speciﬁed.

2. Using a voltmeter, check the voltage and color coding of each conductor at the electrical source.

3. Conﬁrm that the compressor switch and the dispense switch are in the OFF position (see Figure 1).

4. Connect the dispenser to the power source.

5. If plumbing is to be hooked up later, be sure the dispenser is disconnected from the power source. If plumbing has been hooked up, the dispenser is ready for Initial Fill.
