Refrigeration System
| Compressor | ZMD18KVE-TFD-277, Scroll | |
| Refrigerant Charge | 4.0 Kg (8.0 lb.) R-404A/R-452A | |
| Compressor Oil Capacity |
Note 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.
|
1.77 liter (60 oz.) |
| Compressor Oil Type |
Note 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.

| Low Pressure Cutout Switch |
Cutout Cutin |
-17 to -37 kPa, -0.17 to -0.37 bar, 5 to 11 in. Hg vacuum 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). |
