GPH16M Installation Manual

GROUND L EVEL P RE-INSTALLATION D ETAILS

The unit should be set on a solid, level foundation - preferably a

concrete slab at least 4 inches thick. The slab should be above

ground level and surrounded by a graveled area for good drainage.

Any slab used as a unit’s foundation should not adjoin the building

as it is possible that sound and vibration may be transmitted to the

structure.

ROOF TOP PRE-INSTALLATION DETAILS

Ensure that the roof is weather tight and allows proper drainage of

condensation. Use steel or treated wood beams as unit support for

load distribution.

NOTE: To ensure proper condensate drainage, unit must be installed in a level

position.

• To avoid possible property damage or personal injury, the roof must have

sufficient structural strength to carry the weight of the unit(s) and snow or

water loads as required by local codes. Consult a structural engineer to

determine the weight capabilities of the roof.

• The unit may be installed directly on wood floors or on Class A, Class B,

or Class C roof covering material.

• To avoid possible personal injury, a safe, flat surface for service personnel

should be provided.

ROOF CURB INSTALLATIONS ONLY

NOTE: Sufficient structural support must be determined prior to locating and

mounting the curb and package unit.
