3. Install the 1”or 2” filter.
Sound Attenuation Pad
For sound-sensitive installations, a vibration pad (field
provided) should be placed beneath the horizontal or
vertical equipment. For the horizontal unit, the pad should
be approximately twice the size of the unit foot print. For
the vertical unit, the pad should be .5 in. thick, and equal to
the overall unit foot print.
Hanging the Horizontal Unit
To hang the horizontal configuration (see
Figure 54, p. 57
):
1.
Install the hanging isolators (located in the return-air
section of the unit) into the four hanging brackets.
2. Secure the equipment to a joist, concrete, etc. with the
use of 3/8 in. field provided (all-thread) rod. Each
corner should contain field provided nuts and washers
to complete the hanging installation.
3. Slope horizontal units in two directions. The unit
should contain a dual .25-12 pitch toward the drain
connection. This will insure proper drainage of the
unit. All plumbing to the unit should conform per
national and local codes and is the responsibility of the
contractor.
Condensate Drain Connection
Install proper trapping to the equipment. The unit drain
connection is .75 in. NPT for all GEV .5 to 25 ton and GEH
.5 to 5 ton and EXH/V .5 to 6 ton models. For 6 to15 ton GEH
models, the drain connection is .5 in. PVC schedule 40
pipe.
When designing the condensate trap for the water-source
system, it is important to consider the unit draw-thru
design requiring negative pressure trapping.
In a properly trapped system, when condensate forms
during normal operation, the water level in the trap rises
until there is a constant flow. It is imperative to maintain
water in the trap and not allow the trap to dry out during
heating season. Keeping trap primed at all times will
enable the water to flow properly. See
Figure 55, p. 57
for
appropriate dimensions required in a negative pressure
system.

WARNING
Risk of Unit Dropping!
Failure to follow instruction below could result in death
or serious injury. To prevent modules/subassemblies
from dropping, ALWAYS place, assemble, and suspend
them one at a time.
