Floating Thermometer: A thermometer that floats on the water surface with the main sensing bulb in the water. Indicates the ac- tual pool or spa temperature it’s floating in. A tie on type will work the same.
Flow Control Valve: A valve or check valve that controls water flow either automatically or manually.
Freon™: Trade name for a type of refrigerant. The heat transfer medium used to transfer the generated heat to the pool water, in the vapor compression cycle of the heat pump system. Changing from a gas to a liquid state in cycles.
Full Prime: A reference used to describe a water pump running normally without air entering into the system, running at full ca- pacity.
Gas Chlorine: Chlorine in a pure state, gas.
G.P.M. : Gallons per minute, used to measure flow rate
Heat & Cool: The unit, the heater, the appliance referenced in this manual. A reverse cycle unit capable of both heating and cooling.
Heat Exchanger: A manifold where the compressed hot freon gas transfers its heat to the pool water. A tube within a tube. Hot freon gas passing through one tube and water passing through the other tube, bent in a coiled fashion. Made from a cupronickel metal alloy.
Heat Loss: The act of the pool losing heat due to certain conditions such as weather, wind, evaporation, radiance, convection etc.
Heat Pump: The unit, the heater, the appliance referenced in this manual.
Icing Up: Ice forming on the evaporator coil.
In Line Type Chlorinator: A chlorinating device that is mounted directly on the piping, that has an internal manifold within the plumbing, used to allow water flow through the containment, where a solid tablet type chlorine is held. This type requires no water tubing in and out of the containment.
Injection: In regard to feeding pool chemicals into the water flow in whatever fashion.
Installer: Same as dealer, person or company where the unit was purchased.
Internal Adjustments: Any part or component inside the cabinet of the unit.
Lint Trap Basket: A strainer type basket that collects debris and prevents such from being trapped in other equipment, including the heat exchanger.
Liquid Chlorine: Chlorine in a liquid form, (sodium hypochlorite).
Long Term Freeze: When the outside air temperature drops below 36 degrees as part of a seasonal weather change lasting for an ex- tended period of time.
Marcite: A white plaster type pool wall and surface finishing ma- terial made of white Portland cement and marble dust.
Migrate: Referring to concentrated chlorine moving through the filter system plumbing with or without the water flowing.
Motorized Plumbing Valves: Valves that are driven by low volt- age motors mounted on top of such a valve. Usually used to change from pool to spa mode via a control switch or device without hav- ing to go to the filter system and turn these valves manually.
Muriatic Acid: A liquid acid that is used to lower the Ph of pool water. Handle with extreme caution. (Use a dry powder acid for
spas.)
Normal Operation: When the heat pump is running as intended by the manufacturer.
Nozzle Attachment: A device attached to the end of a garden hose, that increases pressure and controls direction.
On/Off Switch: Located on the unit next to the thermostat dial use to shut the unit off and on, so you do not have to move the thermo- stat or shut off the circuit breaker to control the unit.
Ph: A term used when determining the alkalinity or acetic nature of water.
Pool/Spa Combination: When you have a pool and spa together, where the two body’s of water are connected by a
PPM: Parts per million. Use as a term to tell you how much of a certain chemical ratio is in the water.
Pressure Switch: A device inside the heater, that senses water pres- sure and keeps the unit from running when there is little or no water flow going through it.
Radiant Heat Loss: When the water loses heat through the walls and floor of the pool shell.
Return: The term used to indicate water flow direction back to the pool, after it passes through the filtering system. There are ori- fices in the pool called return outlets.
Run Dry: When any pool equipment is running without water, usually causing some sort of damage.
