Caution for an Inverter-based Refrigeration Unit
(1) Even after turning the power OFF, voltage still remains in the charged part. Until the LED (red) of the Inverter
A1000 and Inverter V1000 turns off (until the capacitor discharges the potential), approximately 5 minutes are
required. Do not touch the charged part.
(2) Phase-advancing capacitor is prohibited
Do not attach a phase-advancing capacitor to an inverter compressor. It may cause inverter failure or capacitor
breakage.
(3) Inverter noise prevention
Take as much distance as possible from the wiring of a radio receiver or wired broadcasting.
Inverter noise may cause undesired noise sound.
(4) The two-stage compression mechanism prevents temperature rise of the second stage discharge gas of the
compressor.
During the operation with a small quantity of refrigerant in the refrigeration circuit, a protection device (the CR2-
EN-PCB) makes the compressor to stop. Avoid refrigerant shortage operation.
(5) Rotary compressor consists of high precision components. Use caution during piping work to avoid contamination
of dust, metal powder, or oxide scale, etc.

General Cautions
Each unit of the equipment should be placed by selecting the most convenient location such as easy to install,
operate or maintain.
(1) Each unit should be placed to make the piping and wiring length as short as possible and easy to install.
(2) Controller should be located within the reach of the user’s hand for convenient daily operations (RUN, STOP,
reset warning, etc.). Do not locate the controller in a place easily accessed by the people other than the user.
(3) Install the refrigeration unit at a location easy to be serviced for daily maintenance and inspection.
Daily maintenance and inspection involves checking the operation pressure, compressor operation condition for
abnormal sound or vibration.
