C. Unplug Condensation Drain Holes - The heat pump extracts humidity from the air as it passes through the coil, similar to the way a cold drink outside “sweats” on a hot day. This con- densation drains from the bottom of the unit.
1.Routinely check to be sure the condensation drain holes in the base of the unit are not plugged with dirt or debris.
2.If condensation becomes a problem, optional drain pans are available from your heat pump distributor or pool dealer.
IX. Troubleshooting
If your heat pump does not operate, or simply does not heat your pool water, the indicator lamps on the front control panel (see Section IV) can provide valuable clues as to what is wrong, and may even indicate precisely what the problem is. Always observe these lamps before calling a service representative. By reporting on the telephone which lamps are ON and OFF, the service rep may be able to solve the problem without the expense of a service call.
A. UNIT IS RUNNING, BUT NOT HEATING
•Is water flow through the unit adequate? Check the unit for obstructions, such as a clogged filter pump strainer, a dirty filter, or valves not positioned correctly.
•Is the ejected air from the unit
•Is water condensing on the evaporator and internal copper pipes? This is also evidence of heat removal from the air. When the air is cool with low humidity, condensation may not be evident.
•How long has the unit been operating? During initial pool heating in cold weather, it may require a week to elevate the water temperature to a comfortable level. Normally, it takes about 4 days.
How many hours per day is the unit operating? Remember that the heat pump only operates while the pool pump is running. Set the time clock to permit 24 hour per day operation. After the desired temperature is reached, return the unit to normal operation of
NOTE: If the pool pump and heat pump shut OFF before the water temperature is raised to the desired level, you must lengthen the running time of both. To do this, reset the time clock dial for the longer running time, or manually operate the pump with the timer override switch. Since the heat pump capacity and efficiency are both greater at higher ambient air temperatures, run time should be set to take advantage of all daylight hours, when the air is generally warmer.
•Is airflow through the unit being obstructed? Restrictions such as shrubbery, tall grass, dirty coils, or any other obstruction to airflow will reduce performance.
•Is the pool blanket/cover being used? Unblanketed pools can lose up to 10 degrees per night compared to 4 degrees or fewer when a blanket is used. Without a blanket, the total heat gained during the day can be lost overnight.
•Are rapid heat losses occurring in some other way, such as high wind, spillage, rainfall, flow through solar panels at nights, or a high water table?
