Applications
Unico System designed and built evaporator coil modules can be easily installed with the matching Unico System blower modules. The evaporator can be matched to most types of remote Condensing Units or Unico Heat Pumps. See ARI directory or call factory for capacities and ratings.
Construction
The cabinet is constructed of 22 gauge (0.030-in, 0.762- mm) galvanized steel with removable access panels on both sides for ease of service. The cabinet is fully lined with closed cell insulation. The cabinet does not contain fiberglass insulation. Easy snap latches are included for quick field assembly.
Unico designed coils are constructed of evenly spaced aluminum fins mechanically bonded to copper tubes. The tubes are 3/8" (9 mm) diameter. Full fin collars provide the greatest tube-fin contact for excellent heat transfer. All coils are slanted, except the MC4860C or H model, which feature an ‘A’ coil to provide the maximum amount of heat transfer surface.
The coil is pressure tested and then factory leak tested.The drain pan is constructed of stainless steel for maximum corrosion protection with a 3/4" (19 mm) FPT drain connection. All refrigerant lines are sweat connections extending on the outside of the cabinet.

Controls
All evaporators are supplied with an expansion valve and anti-frost switch. The heat pump coil includes a TXV with internal check valve for proper operation in the heating cycle. All expansion valves feature mechanical threads (Chatleff type) connections for easy installation. All cooling-only valves include an inlet strainer. Also, for heat pump applications, a 24-volt relay switch that bypasses the anti-frost switch during the heating mode. The switch is packed loose inside the module for field installation in the space provided in the control box.
