Power source
For stable and reliable cooling operation, check the
following items before connecting the freezer to a power
source. (Fig. 3)
■ Voltage of the power source: 115 V, 60 Hz
■ Receptacle of the power source: NEMA reference 5-20R
(The equipment has a NEMA 5-20P plug.)
If not, it is necessary to install 5-20R receptacle by qualified engineers.
■ Current capacity of the power source: 20 amperes
■ Rating amperage of the circuit breaker or fuse used in the power line: 20 amperes
(Use item delay type in case of fuse.)
■ Do not connect the other equipment to the same power line to avoid voltage drop.

Ground (earth)
The ground (earth) is for preventing the electric shock in the case of the electrical insulation is somehow
degraded. Always ground the unit at the time of installation.
WARNING
Use a power supply outlet with ground (earth)
to prevent electric shock. If the power supply outlet is
not grounded, it is necessary to install a ground by qualified engineers.
Never ground the unit through a gas pipe, water main, telephone line or lightning rod.
Such
grounding may cause electric shock in the case of an incomplete circuit.
