Figure 33. To remove the main drain pan on vertical fan-coil units, disconnect the clips holding the pan to the fanboard.

Horizontal units:

To remove the main drain pan on a horizontal fan-coil unit, peel the insulation from the edges of the pan’s underside to access the mounting screws. Remove the screws and lower the end of the drain pan closest to the control box. Remove the drain spout by pulling it from the hole in the chassis end panel. See Figure 34.

Vertical units:

To remove the main drain pan on vertical fan-coil units, disconnect the clips holding the pan to the fanboard. Disconnect the main and overflow drain hoses and slide pan forward to remove. See Figure 33.

Winterizing the Coil

Note: Do not operate the fan-coil unit without the main and auxiliary drain pans in place to prevent condensate leakage.

Make provisions to ensure adequate protection against coil freeze-up. If the fan-coil units are not in operation, the coil/s should be vented at the factory vent/s and drained at the piping system drain port/s. See Table 38 on page 94 for approximate piping package volumes for piping systems using ethylene glycol. Table 39 on page 94 lists approximate hydronic coil volumes.

It is necessary to properly prepare the units for cold weather. If a coil is not in use and is subject to temperatures below 32° F, drain the coil to prevent coil freezeup. Locate the drain (installer supplied) in the field piping system.
