Installation

Supply-Air Ductwork

Install the 1" (25.4 mm) supply-air duct flange to the vertical and horizontal equipment with the (8) 5/16" (7.94 mm) factory supplied Torx head screws. The duct collar assembly for each unit is located:

•Model GEH 1/2 to 5 ton = in a box on the side of the unit

•Model GEV 1/2 to 10ton = inside of the refrigeration section of the unit

•Model GEH 6 to 15 ton = of the re- frigeration section of the unit

•Model GEV 12 1/2 to 25 ton = facto- ry ship with a duct collar installed for units containing a top supply- air location. For units with a back or front supply-air location, the duct collar assembly must be or- dered separately from the factory, or be field provided.

When attaching the field ductwork to the unit, provide a watertight flexible connector at the unit to prevent oper- ating sounds from transmitting through the ductwork. See Figure 4.

Elbows with turning vanes or splitters are recommended to minimize air noise due to turbulence and to reduce static pressure.

Return-Air Ductwork

Install the 1"/2" (25.4/50.8 mm) adjust- able filter rack to the horizontal equip- ment only with the use of (4) 5/16"

(7.94 mm) factory supplied Torx head screws. The vertical equipment factory ships with the filter rack and filter(s) in- stalled.

When attaching the field ductwork to the unit, provide a water tight flexible connector at the unit to prevent oper- ating sounds from transmitting through the ductwork. See Figure 5.

Elbows with turning vanes or splitters are recommended to minimize air noise due to turbulence and to reduce static pressure.
