IX. Troubleshooting, Unit is RUNNING, but not Heating

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 8-10° cooler than incoming air? If so, the unit is extracting heat from the air and transferring it to the pool.

•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 8-10 hours per day.

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?

5100, 6100 specifications

Raypak has long been recognized as a leader in the pool and spa heating industry, and their models, the 6100 and 5100, stand out for their innovative features and advanced technologies. Both models are designed to provide efficient heating solutions for residential and commercial applications, ensuring that pool and spa enthusiasts enjoy optimal water temperatures year-round.

The Raypak 6100 is equipped with a robust heat exchanger made from copper and brass, ensuring excellent heat transfer and corrosion resistance.

It employs a digital thermostat and a user-friendly control panel, providing precise temperature control and ease of operation. The 6100 also features built-in safety measures, including a high-limit switch and a pressure switch to prevent overheating and ensure safe operation.

In contrast, the Raypak 5100 offers a slightly lower BTU output, making it suitable for smaller residential pools or spas. Nevertheless, this model does not compromise on efficiency or performance. Like the 6100, the 5100 utilizes a copper and brass heat exchanger, which maximizes heat transfer while ensuring durability. The digital controls on the 5100 also provide ease of use, featuring intuitive settings that allow users to fine-tune their heating preferences.

Both models utilize Raypak's exclusive polymer headers, which provide superior resistance to corrosion and longevity compared to traditional materials. These innovative designs prevent scale buildup and ensure efficient operation over time. Additionally, Raypak's heaters are designed for versatility, capable of running on both natural gas and propane, making them suitable for various settings and configurations.

Another key characteristic of the Raypak 6100 and 5100 is their commitment to energy efficiency. Both heaters are engineered to meet or exceed energy efficiency standards, reducing operational costs while minimizing their environmental footprint. With a streamlined design, installation is straightforward, and routine maintenance can be carried out with minimal effort.

Ultimately, the Raypak 6100 and 5100 models present excellent choices for anyone seeking reliable and efficient heating solutions for their pools or spas. With advanced technologies, durable construction, and an emphasis on user control and safety, these heaters are designed to meet the needs of modern pool and spa owners, ensuring comfort and enjoyment with every use.
