Bryant 551B III. Install Condensate Drain Line and External Trap, IV. RIG and Place Unit

Fig. 1 — Horizontal Conversion Panels

III.STEP 3 — INSTALL CONDENSATE DRAIN LINE AND EXTERNAL TRAP

Condensate drain connections are located at the bottom and end of the unit. Unit discharge connections do not determine the use of drain connections; either drain connection can be used in vertical or horizontal applications.

When using the standard end drain connection, make sure the plug (red) in the alternate bottom connection is tight before installing the unit.

To use the bottom drain connection for a roof curb installa- tion, relocate the factory-installed plug (red) from the bottom connection to the end connection. See Fig. 4. The piping for the condensate drain and external trap can be completed after the unit is in place. The center drain plug looks like a star connection, however it can be removed with a 1/2-in. socket drive extension.

All units must have an external trap for condensate drain- age. Install a trap at least 4-in. deep and protect against freeze-up. If drain line is installed downstream from the external trap, pitch the line away from the unit at 1 in. per 10 ft of run. Do not use a pipe size smaller than the unit con- nection (3/4 in.). See Fig. 5.

IV. STEP 4 — RIG AND PLACE UNIT

Inspect unit for transportation damage. File any claim with transportation agency. Keep unit upright and do not drop.

Spreader bars are not required if top crating is left on unit. Rollers may be used to move unit across a roof. Level by using unit frame as a reference. See Table 1 and Fig. 6 for additional information. Operating weight is shown in Table 1 and Fig. 6.

Lifting holes are provided in base rails as shown in Fig. 6 and 7. Refer to rigging instructions on unit.

A. Positioning

Maintain clearance around and above unit to provide proper airflow and service access. See Fig. 7.

Position unit on roof curb so that the following clearances are maintained: 1/4 in. clearance between the roof curb and the base rail inside the front and rear, 0.0 in. clearance between the roof curb and the base rail inside on the duct end of the unit. This will result in the distance between the roof curb and the base rail inside on the condenser end of the unit being approximately equal to Fig. 2, section C-C.

Do not install unit in an indoor location. Do not locate unit air inlet near exhaust vents or other sources of contaminated air.

Although unit is weatherproof, guard against water from higher level runoff and overhangs.

After unit is in position, remove polyethylene shipping wrap- per and rigging skid.
