TROUBLE SHOOTING 10 INTRODUCTION The Water* Source swimming pool and spa heat pump utilizes water as the heat source rather than air. The practical recovery of heat stored in lakes, canals, oceans, wells, cooling towers or other viable heat resources is a cost—effective method of conserving energy. The Water-Source swimming pool / spa heat pump will provide many years of trouble-free service because of it's design; — A non -corrosive casing protects components from corrosion. — The aluminum chassis wifi not rust. — The insulated evaporator prevents condensate from forming inside the unit. - Acrylic paint resists aggressive salt air in coastal climates. - A Scroll compressor is highly efficient and reliable with low sound levels. The Water* Source uses a "refrigerant vapor compression cycle11 to extract 'Tree" heat from one location (the source water) and delivers it to another (the pool). You pay only for the electricity to accomplish the heat transfer. The Water*Source uses two heat exchangers and makes two heat transfers. One captures heat from the source water and the other transfers heat (enhanced by the compressor) to the poci water. Heat exchangers are a ''tube within a tube". Water flows within an inner tube as the compressor circulates vaporized refrigerant within .a surrounding tube, flowing "counter1' to the poof water flow. Heat is conducted through the cupro—nickel inner tube designed to withstand fresh, salty, or chemically treated poo! or spa water. AquaCal hie. Si Petersburg, !■!, [1 ] WS ij&rics -■ May, 1994 640 UMAN 05?4 LOCATING THE UNIT A. If the heat pump is installed outdoors: - Mount on a "pre-cast" concrete near the pool filter and pump. - The unit may be installed inside an equipment room since it does not require outside air. - Make certain the unit is not set on a base that joins a building foundation. (sound abatement). - If necessary, rubber isolation pads may be placed under each corner of the heat pump. B. The one piece cover lifts up and off the chassis for access to piping and electrical components during installation or service. Allow adequate clearance above and around the unit to permit removal and access to the control panels on the front side of the chassis. — The unit should be located at least 18" from any wall to permit connecting of rear piping and the electrical connections. II. ELECTRICAL WIRING A. Heat pumps are available in several line voltages: 208/230 volt - 60 Hz - 1 phase models through 10 horsepower, using 1 or 2 compressors. (Common in North America). 208/230 volt - 60 Hz — 3 phase models through 10 horsepower using 1 or 2 compressors. (Common in North America). 380 volt / 50 Hz — 3 phase models through 10 horsepower using 1 or 2 compressors. (Common in Europe). 460 volt / 60 Hz — 3 phase models from 5 to 10 horsepower using 1 or 2 compressors. (Common in North America). B. See the cover or electrical panel name plate for minimum circuit ampacity and and maximum fuse size. C. The Power Wiring box for connection to “supply power" is located on the side of the Control Panel at chassis front D. The Control Wiring box for connection of control wiring is located on the side the Control Panel at the chassis front. E. The Grounding Lug (bonding lug) is located in an Electrical Panel and must be used to ground the unit as a safety precaution against electrical shock. F. All wiring must be a copper conductor only and must comply to the National Electrical Codes including Articles 680 and 440; NFPA 70 latest edition; and all state and local codes. II IMPORTANT: To protect against mixed phasing, make sure all power wires are matched properly, i.e. Supply L1 to Contactor L11 L2 to L2, and L3 to L3. AquaCal Inc. St Petersburg, FL [2] WS Series - May, 1994 IJI. POOL WATER PIPING Piping for connection to the WATER*SOURCE heater should be in Schedule 40 PVC or a material acceptable to the local code authority. Metal heat sinks are not required. A. The heat pump unit requires only a portion of the water normally circulated by the pool filter pump. - Some pool water must "bypass" to the heat pump for heating, then return to the pool piping. To build an 'automatic bypass", install: 1.Tee from the pool piping prior to the heat pump. PURPOSE: To direct water to the heat pump. 2. Tee to automatic bypass valve to stablize flow in all filter conditions. Use 7-13 pound spring check valve. 3. Ball valve at heater inlet PURPOSE: Isolation and balancing at start-up. Throttle valve for tuning water flow. 4. Thermometer tee and well at the heater’s "entry''. PURPOSE: For visual monitoring of the "real" pool temperature at the water inlet. 5. ‘Diversion valve between tees in the pool piping, (ball or butterfly valve). PURPOSE: To force water to the heater. NOTE: To balance a bypass system, a valve must be used between the two tees in the pool p...
