Page 10: Positioning Equipment
1.2 Positioning Equipment Failure to heed the following may result in damage to equipment. NOTICE Do not install equipment inside of a building. Outdoor Use Only Do not install equipment inside of a room or building. Heat Pumps require unobstructed air flow for proper operation. Heat Pumps should never be installed indoors or in a location where air flow is restricted.
Page 11: Clearances
1.3 Clearances Proper air circulation is required for the heat pump to operate efficiently. The following diagrams show the minimum clearances required for the proper operation of the heat pump. Avoid storing chemical containers near the heat pump. The chemicals can cause equipment damage. Avoid placing objects near or on top of the heat pump.
Page 12: Plumbing
1.4 Plumbing 1.4.a Plumbing Requirements Failure to heed the following may result in damage to equipment. NOTICE Do not use glue on the threaded portion of the equipment’s unions. A glued-in- place union will prevent the equipment from being properly winterized. The heat pump must receive water flow within the specified minimum ranges under worst-case conditions such as a fouled water filter.

Page 16: Water Connections To Heat Pump
1.4.c Water Connections to Heat Pump Heat Pump union sizes are specified on diagrams. Connections to site plumbing are made via PVC solvent cement to the female slip socket of the plumbing unions. Plumbing unions are available from Eco Therm. See "Available Accessories" on page 44. Failure to heed the following may result in damage to equipment.
Page 17: In-Line Chlorine Feeders
1.4.d In-Line Chlorine Feeders Place in-line chlorinators downstream from the heat pump and as low in elevation as possible. If an erosion type feeder is used, always install a Hartford Loop to protect internal heat pump components. Heat Pump with Hartford Loop 1.4.e Water Flow Rates Maintain water flow rates as indicated.
Page 18: Adjusting Water Flow Using Δt (Delta-T)
Check for improper valve settings. A partially closed valve after the filter, or a full-open bypass around the heat pump, will cause insufficient water flow through the heat pump. The maximum static pressure (or operating pressure) is 50 pounds-per-square-inch (PSI). These specifications relate to the heat pump only.
