INSTALLATION CONTINUED
Ductwork
Properly sized and installed ductwork is critical to reliable
performance of the unit and system. The DC Series B is
field convertible for down flow or left and right horizontal
supply and return duct connections. The DC Series B is
shipped from the factory with all duct connections capped
off. Simply remove the duct caps required for duct
installation. Unit connection sizes are in the engineering
specification literature. All ductwork must be installed
according to local codes, practices and requirements.
Industry manuals should be used as a guide to sizing and
designing the duct system.
Ducts passing through unconditioned spaces must be well
insulated with vapor barrier to prevent condensation.
Condensate Piping
A condensate trap must be provided by customer.
Drainage of condensate directly onto the roof is acceptable
if permitted by local codes. It is recommended that a small
drip pad of either stone, or tar, wood or metal be provided
to prevent any possible damage to the roof. If condensate
is to be piped into the building drainage system, the drain
line must penetrate the roof external to the unit. Refer to
local codes for additional requirements.
