Pool Water Heating Problems (Water-Cooled Units Only)
NOTE:
1.
Water-cooled models include a water proving switch to confirm water flow before the
water heating mode can be activated.
2.
Lack of water heating may be a symptom of another refrigeration or controls problem
not related to the water circuit.
3.
Under normal conditions the water temperature rise across the dehumidifier should be
between 4° and 15°F.
•
LOW TEMPERATURE INCREASE OF WATER is a symptom of excessive water flow
rate. Excessive water flow can erode the water condenser and cause premature
equipment
failure.
•
HIGH TEMPERATURE INCREASE OF WATER is a symptom of insufficient water flow.
This can be caused by an undersized pump, insufficient water diversion or restrictions
in the water piping such as dirty filter(s). This would also lead to high refrigerant
discharge operating pressures in the water heating mode.
POSSIBLE CAUSE
Air and pool water temperature
imbalance
Poor air distribution
Unit airflow is too high
Unit is undersized
UNITS EQUIPPED WITH WALL-
MOUNTED SENSOR OPTION:
1) Controller installation
2) Air stratification
REMEDY
Adjust set-points so that air
temperature is 2°F above water
temperature. 80°F water and 82°F air
recommended for most jobs.
Evaluate duct design and dehumidifier
location.
Evaluate system airflow.
Re-evaluate unit sizing. Check for
initially neglected sources of heat or
humidity.
1) Assure that sensors are NOT
located near supply registers,
windows, heaters, saunas, etc.
2) Consider continuous blower
operation.
