Refrigeration System Specifications
Compressor:
Model No.:
ZMD18KVE-TFD-277, Scroll
Refrigerant Charge:
4.0 Kg (8.0 lb.) R-404A
Compressor Oil Capacity
1.77 liter (60 oz.)*
Compressor Oil Type:
Polyol Ester Based Type (required), (refer to Tool Catalog)**
*When the compressor is removed from the unit, oil level should be noted or the oil removed from the compressor should be
measured so that the same amount of oil can be maintained in the replacement compressor.
**
Do not
use or add standard synthetic or mineral oils to the refrigeration system. If Ester based oil becomes contaminated
with moisture or with standard oils, dispose of properly —
Do Not Use!
High Pressure Cutout Switch:
Cutout
3240 ± 48 kPa, 32.4 ± 0.5 bar, 470 ± 7 psig
Cutin
2586 ± 262 kPa, 25.9 ± 2.6 bar, 375 ± 38 psig
Low Pressure Cutout Switch:
Cutout
-17 to -37 kPa, -0.17 to -0.37 bar, 5 to 11 in. Hg vacuum
Cutin
28 to 48 kPa, 0.28 to 0.48 bar, 4 to 7 psig
High Pressure Relief Valve:
Relief Temperature
99 C, 210 F
Vapor Injection Control:
Modulation Cool or Power Limit
Vapor injection valve is energized (open) continuously when
the compressor duty cycle (ON time) is 100 percent (Full
Cool). High compressor discharge temperature may cause
the vapor injection valve to energize (open) but only while
the Compressor Digital Control valve is not energized
(closed).
Compressor Discharge Temperature Control:
Vapor Injection Valve Energizes (Opens)
138 C (280 F)
Vapor Injection Valve De-energizes (Closes)
6 C (10.7 F) below energize temperature
(132 C [123 F])
Compressor Shutdown (Auto Reset)
148 C (298 F)
Vapor Injection Valve (Compressor):
Voltage
24 Vac
Current
0.85 amps
Cold Resistance
5.6 ohms
Compressor Digital Control Valve:
Voltage
24 Vac
Current Draw
0.85 amps
