Installation
Sound Attenuation Pad
For sound sensitive installations, a vi- bration pad (field provided) should be placed beneath the horizontal or verti- cal 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 1/2" (12.7 mm) thick, and equal to the over- all unit foot print.
Hanging the Horizontal Unit
To hang the horizontal configuration:
(1)Install the hanging isolators (locat- ed in the
(2)Secure the equipment to a joist, concrete, etc. with the use of 3/8"
(9.7 mm) field provided
(3)Unit slope or pitch should conform to national and local codes. This is the responsibility of the contractor.
Condensate Drain Connection Install proper trapping to the equip- ment. The unit drain connection is 3/4" (19 mm) for all GEH and GEV models.
When designing the condensate trap for the
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 dur- ing heating season. Keeping trap primed at all times will enable the water to flow properly. See Figure 6 for appropriate dimensions required in a negative pressure system.
WARNING
Improper Unit Lift!
Test lift unit approximately 24 inches to verify proper center of gravity lift point. To avoid drop- ping of unit, reposition lifting point if unit is not level. Failure to properly lift unit could result in death or serious injury or possible equipment or prop-
