Unitary Products Group 036-21335-002-A-1102 DESCRIPTION Evaporator blower units are designed with two distinct modules to provide maximum application flexibility. The 25, 30 and40ton unitsare shippedas singlepackageswiththe blower module mounted on top of the coil module, The blower module can be repositioned in the field to meet almost any installation requirement. Blower and coil modules for the 50 ton units are shipped separately to simplify handling. These modules can be connected in the field with the same flexibility as the smaller units. The blower module includes the blower wheels and room for a field-mounted motor and drive. The coil module includes direct expansion coils, 2 in. throwaway filters, liquid line solenoid valves for both capacity reduction and pumpdown, thermal expansion valves, distributors and a condensate drain pan. Every evaporator coil is pressurized with air to 325 psig and leak tested under water. After the headers are brazed onto the coil and the coil is installed in the unit, the coil is pressurized with a combination of Refrigerant-22 and nitrogen to 150 psig for pressure testing and additional leak testing. After the coil is...
