Effect
Too little chlorine Excessive release of chloramines resulting in foul odors and high levels of bacteria, fungi, viruses etc.
High pH or high total alkalinity Scale formation in the water heaters, pipes etc.
Low pH or low total alkalinity Corrosive water damages metal components such as water heaters
Pool water quality is not only a health
and comfort problem, it also affects the
performance of mechanical equipment.
The owner/operator of the natatorium is
responsible for maintaining proper pool-
water chemistry. Water treatment
instructions MUST be obtained from the
pool equipment or pool chemical supplier .
There are also excellent books and
videos available on this subject.
IMPORTANT!
Failure to maintain proper chemistry
in the pool water will result in scale
formation and/or corrosion which
may void the DRY-O-TRON® warranty.
Some Basics
ΔΔ
Foul odors in the pool area
The powerful, stinging smell that is
often associated with indoor pools is that
of chloramines, not excessive chlorine.
The presence of excessive chloramines
indicates a need for corrective action.
The smell is actually a symptom of
under-chlorination which can result in
high levels of bacteria, fungi, viruses etc.
Maintaining proper chlorine levels and
constant pH levels will eliminate the foul
odors. Airborne chloramines also have a
strong affinity to pure water such as con-
densate. Stagnant condensate in walls
and on windows can accumulate consid-
erable amounts of chloramines which
make the condensate acidic and corro-
sive. The prevention of condensation
coupled with proper pool water treatment
will reduce this problem.
ΔΔ
pH level
High pH level (alkaline range) enhances
scale formation which damages the pool
water heaters. With low pH levels the
water is acidic and corrosive. Metal
parts in pumps and water heaters may
be damaged.
Proper pool water management will
help ensure the long life for which
your pool equipment has been
designed.
Pool-water testing should include (at
minimum) monitoring and recording:
ΔΔ
pH
ΔΔ
Total alkalinity
ΔΔ
Free (available) chlorine
ΔΔ
Combined chlorine
ΔΔ
Calcium hardness
ΔΔ
Water temperature
Corrosion
Unbalanced pool-water chemistry will
lead to health problems and deterioration
of the building, and mechanical and elec-
trical equipment. Conversely, a well
maintained pool with proper water treat-
ment and sufficient make-up air will offer
a healthy environment and will not cause
damage to the equipment.
Dectron has taken all commercially
feasible precautions to protect the
DRY-O-TRON® units against corrosion
caused by accidentally high levels of
chemicals. This means that the equip-
ment should be resistant to unbalanced
pool water (high or low pH level) and air-
borne oxidizing agents such as chlo-
ramines for a short period of time.
Major corrosion protection features are:
ΔΔ
Cupro-nickel tubing of pool water
heater circuit
ΔΔ
HyPoxy® coated fins on
dehumidifying and reheat coil
ΔΔ
Use of plastic, cadmium plated,
brass and/or stainless steel
hardware wherever possible
ΔΔ
High-quality painted cabinet
Pool owners can further protect
their investment by following these
simple guidelines for the entire
system design:
1. provide an adequate amount of
make-up air,
2. install and maintain an automatic
pool-water treatment system, and
3. provide quality training for the
maintenance personnel.
DRY-O-TRON
®
units should be
serviced by qualified Dectron-
trained technicians.

NOTICE
Risk of corrosion. Can cause property damage.
Pool chemicals are very corrosive and can cause severe property damage. Read
and follow these instructions and all applicable codes.
For salt-water pools, contact
Dectron before exceeding
3000 ppm salt concentration.
