HEATING DEHUMIDIFIERS
POOL WATER PIPING:
Schedule 40 CPVC thermoplastic or copper piping is
recommended. Standard PVC, aluminum, galvanized, black
iron and cast iron piping must not be used.
The O.D. size of the supply and return water piping must
not be downsized from the connection on the DCA
Dehumidifier. If the main by-pass valve is more than 10 feet
from the dehumidifier, increase the pipe size one size up.
Both the supply and return pipe should be insulated for
best results.
It is very important that the water flow be verified and
matches the chart below.
IMPORTANCE OF POOL WATER CHEMISTRY
It is the responsibility of the indoor pool, spa, whirlpool
or water park owner to maintain correct pool water
chemistry. Poor pool water quality caused by out of
balance pool or spa water chemistry is a serious health
and comfort problem. Many times the so called offensive
“pool water smell” is a tip off that this water chemistry
needs attention. It is the responsibility of the pool or spa
manager to test the water chemistry daily with a pool water
test kit. This kit will analyze PH - total alkalinity - free
available and combined chlorine in the water. Proper pool
water treatment procedures can only be obtained from the
pool, spa or whirlpool equipment or pool water chemical
suppliers. With this also is the verification of proper pool or
spa water temperature.
Poor pool or spa water chemistry will result in the
formation of scale and corrosion within the dehumidification
system which will drastically shorten the effective service
life of the dehumidifier.

STORAGE OF POOL OR SPA WATER CHEMICALS:
This is an area of swimming pool or spa management
that most times is either neglected or forgotten about
altogether with often dire consequences. Pool water
chemicals, by their very nature, are some of the most
corrosive chemicals that are available for non-professional
use.
Under no circumstances should the storage of spa or
pool water chemicals be in the same room with the
dehumidifier. The very corrosive effects of these
disinfectant will quickly attack any and all metal surfaces it
comes in contact with. Not only will the dehumidification
system be effected, but also any pool or spa water heating
systems, pumps or other mechanical devices such as
controls be adversely affected.
Proper storage must be in another area of the building or
in a sealed non-metallic cabinet that will ensure that no
vapor release of the chemicals will occur. It will be easy to
detect, if the early failure of equipment occurs, that
improper chemical storage was the cause.
