Equipment lifting
The SDME series from
Nagas Express
are built on a galvanized steel-metal base frame equipped with lifting
lugs specifically located to help proper lifting of the unit. Employ the use of spreader bar to maintain a
vertical position of the slings and keep them away from the unit casing to prevent
scratches
, surface
blemishes or other structural damages. The lifting lugs are designed to be lifted straight up vertically; the
maximum angle from a vertical lift which is allowed is 30 degrees. All lifting lugs must be used at to distribute
load properly and the equipment must be lifted simultaneously by all the lifting lugs.
Figure 1: Typical lifting method
NOTICE
If using a lift truck, ONLY lift using the perimeter base frame. DO NOT allow forks to lift on unit casing or
unit floor.
There may be bottom mounted external components, such as drain piping, that can be easily damaged.
WARNING!
Injury or death can result from incorrect rigging and lifting, these manoeuvres must be performed by
qualified crane operator with proper equipment using appropriate and approved safety precautions.

Equipment mounting
This equipment must be mounted level to the ground to prevent water from being trapped inside drain pans
and to avoid other operational issues.
CAUTION!
Standing water contributes to poor indoor air quality and unit corrosion.
This equipment is designed for two types of mounting:
1.
Base mounting: The total perimeter base frame structure must be supported level by high density
concrete or adequate steel beam. Refer to the shop drawing for mounting information.
2.
Roof curb mounting: The roof curbs are fabricated of heavy gauge load bearing, galvanized steel, and
must be fully insulated after installation by the installing contractor. Wood nailed strips are provided
for easy attachment of roof flashing. Gasket material is supplied with the unit and must be field
mounted on the curb to seal the joint between the curb and the unit frame. The curb must be
supported along its entire perimeter and any full height cross members as shown on the shop
drawing. Point loading of the roof curbs is not acceptable.
