Split-Apart Unit Assembly

pre-installation

Installation considerations

1.Ensure the tagging information on the fan section nameplate matches that on the compressor nameplate.

2.Remove the connector brackets holding the the sheet metal shipping cover on compressor section. Retain brackets and screws.

3.Remove shipping cover from the compressor section and verify the ship- with packge contains:

•suction and discharge line couplings

•insulation

•sheet metal screws

4.Lift fan section onto the compressor section using the rigging method in Figure I-PC-8 on page 13.

5.Remove skid from the fan section, placing the fan section onto the compressor section. Reference Figure I- PC-9.

6.Install the connection brackets with the sheet metal screws (referenced in step 2) on all sides of the unit. Reference Detail “A” in Figure I-PC-9.

7.Remove the unit panels labeled RU and RL in Figure I-PC-10 on page 17. To remove panels, first remove the four shipping screws located in the corner of each panel. Next, turn the remaining 1/4 turn fasteners to the unlatch position. The panel is supported by a “lip” channel. So, lift the panel up and off the unit to remove it. See Detail “A”in Figure I-PC-9.

8.Connect the drain hose to the drainpan outlet fitting and secure it with the drain hose clamp provided.

9.Circulate nitrogen thoughout refrigerant circuits.

10.Unbraze and remove the caps on the discharge and suction lines in both the compressor and fan sections.

11.Install and braze discharge and suction line couplings.

12.Insulate discharge and suction lines with the insulation provided.

13.Remove panel FLR and open the bottom control panel door, FLL. Pull the fan motor leads (coiled in the fan section) through the knockout in the bottom of the fan section to the control panel. Ensure that the bushing is installed in the hole to prevent the wires from chafing. Refer to the unit wiring diagrams to connect the fan motor leads properly and ensure correct phase sequencing.

IntelliPak Units(UCM) Only

14.Remove panels FML, FMM, and FMR.

15.Pull the circular plug connector (CPC) from the compressor section through the knockouts into the fan section.

Install the bushings (provided on the wiring harnesses) in the knockouts.

16.Using the CPC wiring diagram, connect the male CPC to the female CPC in the top control panel.

17.If the unit has the mixed air temperature option, route the capillary tube on back of the filter rack.

Units with Thermostat Only

18.Remove panel FMR. See Note 1 on Figure I-PC-10.

19.Pull frost protection wires from the bottom control panel throughknockouts in bottom of fan section. Route wires to the appropriate frost protection switches on the evaporator coil. Reference the unit wiring diagrams to connect frost protection wiring connectors.

Air-Cooled Units Only:

20.Route the refrigerant circuit wires for circuits 1 and 2 from the bottom control panel through the knockouts to the solenoid valves. The solenoid valves are located in the liquid refrigerant lines on the right-hand side of the unit. Refer to the unit wiring diagrams to make splice connections.
