Section 1 - Installation and Start-Up
1.1 Location and Unpacking
This unit will operate most efficiently and safely under
these conditions:
• Indoor use
• Altitude up to 6562 ft. (2000m)
• Ambient temperature range 5°C to 40°C
• Maximum relative humidity 80% for temperatures up to
31°C, decreasing linearly to 50% relative humidity at 40°C
• Mains supply voltage fluctuations not to exceed ±10% of
the nominal voltage
• Transient overvoltages according to Installations
Catagories (Overvoltage Categories) II, which is the mini-
mum and normal category
• Pollution Degree 2 in accordance with IEC 664
Locate the unit on a firm, level surface in an area of mini-
mum ambient temperature fluctuation. Avoid installing the unit
near heat-emitting appliances, as heat can shorten component
life and cause inefficient refrigeration.
Avoid placing the unit in a contaminated area with an
excessive amount of dust, or where chemicals or gases are pres-
ent.
Chamber temperature is maintained through the circulation
of forced air. Ensure that the air intake and exhaust vents are
clear of obstruction at all times. Allow 4-5 inches (10cm) of
clearance on all sides of the unit to reduce power con-
sumption and allow free air circulation.
Two wall mounts are attached to the top rear of the unit.
Remove the wall mounts and reverse their position. Reattach to
the unit. Secure the single hole section of the mount to the wall.
A special bolt-nut is supplied for concrete walls.
Remove all packaging
materials and ventilate the
unit thoroughly.
1.2 Leveling
Adjust the feet on the bottom front of the unit to level the
cabinet. Turn each foot counterclockwise until it makes full
contact with the floor.
1.3 Connecting to Power
Connect the unit to a dedicated, grounded power source
using the three-prong power plug. Refer to the electrical data
plate on the unit for electrical specifications.
