Pentair HP 800 Heat Pump User Manual


 
NORMAL RUNNING TIME
The heat pump system extracts the heat from the out-
side air and delivers it to your pool. Therefore it pro-
duces more BTU's (heat) the warmer it is outside. So
take advantage of the higher air temperatures during
the day by setting the timer for the warmest hours. Win-
ter operation (during cold fronts) may require longer
run times up to 16 hours daily.
SET THERMOSTAT TO MAXIMUM
Turn the thermostat dial all the way to the right. You
will turn the thermostat back to a lower position later,
as described on the next page. The fan should now be
turning.
There is a compressor start time delay and generally it
will not start for about 5 to 7 minutes. Cooler air will
come from the fan when the compressor is running.
Become familiar with the compressor sound and remem-
ber the compressor time delay.
Scroll compressors may not start on the first try. Allow
Scroll type compressors several starts and time delay
cycles before the compressor starts. This condition is
most common to new compressors or when starting
during colder air temperatures.

TIME CLOCK SETTING
Now that all the filters are clean and the pump is run-
ning with a full prime, you will need to set the pool
circulation pump timer. Set the filter pump time clock
for a long enough period of time to heat the pool or spa.
The heater will not operate unless there is water run-
ning through the heat exchanger supplied by the circu-
lation pump. Therefore, your pool will only heat dur-
ing the period set on the timer. When setting the timer,
be sure that you shut off the pool circulation pump cir-
cuit breaker. Then follow the timer manufacturers in-
structions to prevent electrical shock. Consult your
dealer first.
INITIAL HEAT UP TIME (HEATERS)
You should start by letting the circulation pump run 24
hours a day until the pool reaches the desired tempera-
ture. Once the pool is up to your desired temperature
you should reset the timer for a cycle of 6 to 18 hours
per day during the hottest part of the day. Heat up time
and operational time will vary with pool size, exposure
and weather conditions. Spas will require considerably
less time to reach temperature, usually in a matter of
hours if a cover is used.
INITIAL COOL DOWN TIME
(HEAT & COOL MODELS)
You should start by letting the circulation pump run 24
hours a day until the pool reaches the desired tempera-
ture. Once the pool is down to your desired tempera-
ture you should reset the timer for a cycle of 6 to 18
hours per day during the coldest part of the day. Cool
down time and operational time will vary with pool size,
exposure and weather conditions.
ADJUSTING THE TIMER
Timer styles vary, read the manufacturers instructions
before attempting to reset timer. Make sure the plastic
guard is in place. On this type of timer, note the On
and OFF trippers located on the clock face. If you
loosen the lock screw on the tripper you can move it to
a new time. Make sure the time of day is correct.
To run the 24 hours needed for the initial heat up, just
remove the "OFF" tripper. When the pool reaches tem-
perature, replace the tripper and set timer to run the water
pump during the hottest part of the day.
