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.
PLUMBING REQUIREMENTS The dispenser must be connected to a COLD WATER system with an operating pressure between 30 and 100 psig (.207 and .690 mPa). This water source must be capable of producing a minimum flow rate of 3 fluid ounces (88.7 milliliters) per second. A shut off valve should be installed in the line that will supply the dispenser. A water filter has been included with the dispenser.
FILLING THE WATER BATH 1. Plug the dispenser into an electrical outlet and turn on the water supply to the dispenser. 2. Flip the dispense switch to ON. The water bath will begin to fill. The water bath will fill and automatically shut off when the water bath is full. 3. Check the sight glass to confirm that the water bath is full (See Figure 5). Once the water bath is full, flip the compressor switch to ON.
CHANGE WATER FILTER CARTRIDGE WARNING The water filter cartridge will need to be changed after 4,500 gallons of use. When the water usage gets close to 4,500 gallons, the blue LED will flash slowly to indicate that it is nearly time to replace the water filter cartridge. When the water usage exceeds 4,500 gallons, the blue LED will flash rapidly to indicate that it is time to replace the water filter cartridge.
