All units must have an external trap for condensate drainage. Units Without Non-Fused Disconnect Option Install a trap at least 4 in. (102 mm) deep and protect against freeze-up. If drain line is installed downstream from the exter- nal trap, pitch the line away from the unit at 1 in. per 10 ft (25 mm in 3 m) of run.
Page 14: Units With Factory-Installed Non-Fused Disconnect
UNITS WITH FACTORY-INSTALLED NON-FUSED DISCONNECT The factory-installed option non-fused disconnect (NFD) switch is located in a weatherproof enclosure located under the main control box. The manual switch handle and shaft are shipped in the disconnect enclosure. Assemble the shaft and handle to the switch at this point.
Page 15 Two types of convenience outlets are offered on 50FC models: Non-powered and unit-powered. Both types provide a 125 volt GFCI (ground-fault circuit-interrupter) duplex receptacle rated at 15-A behind a hinged waterproof access cover, located on the end panel of the unit. See Fig. 21. Figure 22 shows the Convenience Outlet Utilization label which is located below the convenience outlet.
Page 16 The primary leads to the convenience outlet transformer are not factory-connected. Selection of primary power source is a customer-option. If local codes permit, the transformer primary leads can be connected at the line-side terminals on the unit- mounted non-fused disconnect; this will provide service power to the unit when the unit disconnect switch is open.
