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. (Aquatherm AT075) (Aquatherm AT115, AT130 and AT150) 1.2.d In-Line Chlorine Feeders Place in-line chlorinators downstream from the heat pump and as low in elevation as possible. -
Page 9: Water Flow Rates
Water flow exceeding maximum flow rates will negatively affect the total pool filtration performance and may damage the heat pump. This will not be covered under the equipment warranty. FLOW RATES MODEL MINIMUM MAXIMUM AT075 20 GPM (75.7 L/min) 45 GPM (170 L/min) AT115 30 GPM (113.6 L/min) 70 GPM (265 L/min) AT130 30 GPM (113.6 L/min) -
