[1] When there is specification, working fluid is shown by the symbol. This symbol may not be indicated.
(Example: N= Ammonia, F=Hydro Fluoro Carbon, P: Propane)
[2] Means rotor diameter which is 160, 200, 250 or 320.
[3] Means the specifications of the rotor length which is S, M, L or LL (for rotor diameter 250 only).
[4] Means gas discharge direction which is D (sideways) or G (down: except for rotor diameter 320).
[5] Means the specifications of the slide valve, which is D (grooved type) or Z (low Vi type) as special
specifications. When using standard slide valve, symbol is not added and left justified.
[6] When using the short cut rotors, add the symbol "S". When using the standard rotors, symbol is not
added and left justified.
[7]
When the compressor is standard specifications (standard slide valve, H-port, standard compression
ratio, with economizer port and with liquid injection port) without symbols [8] to [10], this symbol is
not indicated, either.
[8]
This symbol is indicated only when specified by the order. This symbol means a discharge port
which is H (Vi=5.8, with gorooveless standard slide valve), M (Vi=3.65, with gorooveless
standard slide valve), MS (Vi=2.63 equivalent, with grooved slide valve), HS (Vi=1.8, with low
Vi slide valve), or MS (Vi=1.3, with low Vi slide valve).
Note: In the case of following specifications set of discharge port and slide valve, variable Vi
slide valve should be adjusted the first character of this symbol (left side to
"S").
Note: If the evaporating temperature of the system exceeds 0 °C under the L port condition,
select a grooved slide valve for the compressor.
In addition, note that grooved slide valve is available to even less than 0
°C evaporating
temperature under the L port condition.
[9] When the compressor is booster specifications, the symbol "B" is added. When the compressor is
standard specifications, symbol is not added and left justified.
[10] This symbol is indicated only when specified by the order. This symbol indicates if there is
economizer port or/and liquid injection port or not. When this symbol is not indicated, both ports
are provided and symbol may be added as “X”.

The meanings of symbols [8] to [10] are shown below as examples.
200VLD: Discharge port is H port. With economizer and liquid injection ports both.
N200VID-MX: Discharge port is M port. With economizer and liquid injection ports both.
N200VLD-MBX: Discharge port is M port. Booster type, with economizer and liquid injection ports both.
N200VLD-HE: Discharge port is H. With economizer port, without liquid injection port
N200VLD-HN: Discharge port is H. Without economizer and liquid injection ports both.
