Curb Mounting
For curbs by PoolPak, see the specific curb drawing that is specifically designed for the ComPak
(Fig. 4-4
)
or for the RoofComPak
(Fig. 4.3)
. For curbs by others, you must use the same dimensions as shown.
The outside dimensions of the curb are such that the base of ComPak® extends over the edge of the curb all
the way around. This aids in preventing rainwater from getting between the base of the ComPak® and the curb.
PP It is the installing contractor’s responsibility to complete the following:
• Flash the curb into the roof
• Connect the supply and return duct to the curb’s duct support rails.
• Connect condensate drain line with appropriate trap
• Seal the curb to the bottom of the ComPak® using the gasket supplied with the curb
• Install counter-flashing provided with the curb separately between the curb and the ComPak unit.
• Seal any piping connections where piping is going through the curb
If specified when ordering, all water piping connections can be made through the curb. These water connections
may include: pool water, condensate, auxiliary hot water coil (optional).
For outdoor units with top duct connections, contractor is responsible for sealing these connections.
