THIS EQUIPMENT MUST BE INSTALLED IN COMPLIANCE WITH THE
APPLICABLE FEDERAL, STATE/PROVINCE, AND/OR LOCAL PLUMBING,
ELECTRICAL, AND HEALTH/SANITATION CODES AND REQUIREMENTS.
CAUTION:
{
RISK OF PERSONAL INJURY, PROPERTY DAMAGE, EQUIPMENT
FAILURE, OR FIRE.
{
Refer all maintenance to qualified personnel .
{
Never operate this equipment with covers, panels, or other parts removed
or not properly secured.
{
Warn all users to clean up spillage immediately, keep storage bin doors
closed, and report any apparent leakage or unusual sounds to responsible
maintenance personnel.
{

INSTALLATION
1. Uncrate the condenser and install the mounti ng legs. Be sure to install the l eg
stabilizer between the legs.
CAUTION:
{
RISK OF PERSONAL INJURY OR EQUIPMENT DAMAGE.
{
Use a suitable lifting means and be careful of sharp edges.
2. Fasten the condenser to the roof or wall using whatever method will satisfy the
building codes in your area. The condenser must not be lower than the
receiver.
3. The line sets are packed separately, with the quantity and length marked on the
carton. Make sure that the lines are correct for your installation.
4. A single circuit condenser installation, which uses one line set, will require a
1-3/4" dia. hole to pass the lines through a ceiling or wall. The lines for a 2
circuit condenser require a 2" dia. hole.
5. Each line set consists of a 3/8" l iquid line, and a 1/2" insulated discharge li ne.
Connect the 3/8" line to the lower (liquid) fitting on the condenser, and to the
"Refrigerant In" on the ice maker. The 1/2" line connects to the upper (inlet)
fitting on the condenser, and the "Refrigerant Out" on the ice maker.
6. Each fitting on the line sets, condenser and ice maker is self-sealing, and
should be tightened 1/4 turn more than hand tight. Always use a backup

7. The condenser fan motor requires a separate 208-230 volt, 60 Hz, single phase
power supply whi ch complies with all appli cable code requi rements. The system
is designed for continuous fan motor operation. If desired, a condenser fan
cycling control may be installed to stop the fan during cuber off-cycles.
Suggested pressure calibrations are approx. 250 psig ON/220 psig OFF.
CAUTION: For multiple-circuit installations, a separate pressure control must
be installed on each circuit, and all of the controls must be parallel-wired so that
all controls must be open to stop the fan.
