Filter Installation

Figure 5 Horizontal Installation

Filters must be field supplied. The blower cabinet is set up for an internal filter or a remote filter grille or other means may be pro- vided. Refer to ACCA Manual D for remote filter sizing.

To install an internal filter, remove screw securing filter door and slide filter into unit. Some filters are marked for airflow direction, make sure arrow points towards blower if marked. Washable fil- ters are offered as an accessory. Disposable filter sizes are listed in Filter Static Pressure Drop Table.

		Condensate	Drain
		The unit is provided with 3/4" National Pipe Thread (NPT) con-
		densate drains. (Figure 1). Any drain can be used as a primary or
		secondary drain. Condensate drain lines should be insta!led in a
		manner that does not obstruct access to the filter.
		There is a secondary drain fitting supplied with the unit that will
		convert any of the primary condensate drain connections into a
		secondary drain connection. This fitting should be insta!led in any
		of the primary drain connections to convert it to a secondary drain.
		1. Connect the drain lines to the appropriate drain fittings. 3/4"
		PVC or other type of drain line may be used. The drain line
		must not be smaller than the drain fitting.
Field-Fabricated		2. Insta!l a trap	in the drain line below	the bottom of the drain
Drain Pan		pan and pitch	the drain lines down	from the coil at least I/4"
Supports MUST run parallel with blower cabinet	=-_	per foot of run. Horizontal runs over 15 feet long must also
		have an anti-siphon air vent (stand pipe), installed ahead

of the horizontal run. An extremely long horizontal run may require an oversized drain line to eliminate air trapping.
