Energy Tech Laboratories 5358 - Manual (Page 8)

Defrost Sensor: Prevents unit operation if ambient air
temperature falls below a predetermined safe mini-
mum (approximately 42°–48°F, based on humidity).
The compressor will shut OFF but the fan will continue
to run.
Delay Timer: Prevents compressor from short cycling,
which could damage or destroy the hermetic
motor/compressor. Upon water temperature control
satisfaction, or other circuit interruptions, this solid
state device will prevent compressor restart for
approximately 5 minutes.
Controls Operating
Instructions
The electronic board has the capability of memorizing
two different programmed temperature settings as fol-
lows (refer to Fig. 3):
• For a pool, maximum 95°F (35°C)
• For a spa, maximum 104°F (40°C)
To Select Pool or Spa Mode
To have access to either one of these programs, press
the SET key until you see P _S and by pressing the
UP or DOWN key you can switch to POL or SPA.
To Increase the Desired Water
Temperature (Pool or Spa Mode)
Push the SET key until you see POL or SPA. The pro-
grammed temperature will be displayed. Press the UP
arrow to increase the temperature setting one degree
at a time.
To Lower the Desired Water
Temperature (Pool or Spa Mode)
Push the SET key until you see POL or SPA. The pro-
grammed temperature will be displayed. Press the
DOWN arrow to decrease the temperature setting one
degree at a time.
Once the control has been programmed to the desired
pool water temperature, the programmed temperature
will be displayed for approximately 5 seconds. Then
the digital display will display the actual pool water
temperature.
To Select Temperature in °C or °F
Press the SET key until you see F _C. By pressing the
UP or DOWN key you can switch to °F or °C. Once the
temperature display mode has been programmed it
will be displayed for approximately 5 seconds, then
the digital display will return to the actual pool water
temperature in the mode that you have chosen.
System Start-Up
1. Verify that the Digital Board is displaying a temper-
ature and the pool pump is running and water is
circulating properly.
2. Verify that the Board is programmed so that the
desired temperature of the Pool and Spa is higher
than the displayed current water temperature.
3. Allow the heat pump pool heater to operate for a
few minutes to stabilize operating pressures and to
allow various component temperatures to normal-
ize.
4. Verify that the discharge air temperature is approx-
imately 8°–10°F cooler than the air entering the
unit. If not, see the Troubleshooting Section.
Seasonal Start-Up or Annual
Check
1. Remove leaves, pine needles, etc., from the evap-
orator coil. Clean the coil by gently applying a mild
solution of household liquid soap and water.
2. Gently rinse the coil with water; DO NOT use high
pressure.
3. Backwash or otherwise clean the pool filter. If nec-
essary, clean the skimmer basket and pump
strainer.
NOTE: At the beginning of the heating season, or
whenever the pool water temperature is to be raised
several degrees, the pool pump and heat pump pool
heater may need to operate continuously for several
days. During summer months, only a few hours per
day may be necessary, or none at all.
