Always stir pool/spa water before entering the pool/spa to mix in any hot surface layer of water that might exceed healthful temperature limits and cause injury. Do not tamper with controls, because scalding can result if safety controls are not in proper working order. 7. Persons with a medical history of heart disease, circulatory problems, diabetes or blood pressure problems should obtain a physicians advice before using spas or hot tubs. 8. Hyperthermia occurs when the internal temperature of the body reaches a level several degrees above normal body temperature of 98.6°F. [37°C]. The symptoms of Hyperthermia include: drowsiness, lethargy, dizziness, fainting, and an increase in the internal temperature of the body. The effects of Hyperthermia include: 1. Unawareness of impending danger. 2. Failure to perceive heat. 3. Failure to recognize the need to leave the spa. 4. Physical inability to exit the spa. 5. Fetal damage in pregnant women. 6. Unconsciousness resulting in danger of drowning. DEFINITIONS: Suction Outlet - The term Suction Outlet is a fitting, fitting assembly, cover/grate and related components that provide a means for water to exit the pool and into the pump circulating system. Inches of Mercury (in Hg) - A unit for measuring pressure below atmospheric ("suction" or "vacuum") (1.0 inch Hg = .491 PSI) Main Drain - See Suction Outlet PSI - An abbreviation for pounds per square inch. INSTALLATION: Materials needed for Installation The following items are needed and supplied by the installer for all heat pump installations. 1. Plumbing connections: 2 inch PVC pipe Schedule 40 and 2 inch fittings and components as follows: (3) - 2 inch Isolation Valves (1) - 2 inch Check Valve (2) - 2 x 2 x 2 PVC Tee's NOTE: Pipe fittings such as reducers, tees, and elbows cause pressure to drop as water flows through them. Plan the plumbing layout carefully, using as few fittings as possible to connect your heat pump. See plumbing diagram under the heading "Plumbing Specifications and Layout" for more information. 2. Level surface for proper draining. 3. Suitable electrical supply line. See rating plate on the heat pump units for electrical specifications. A junction box is not needed at the heat pump; connections are made inside the heat pump electrical compartment. 4. Electric disconnect switch that will interrupt all power to the unit.
