This manual should be maintained in legible condition and kept adjacent to the heat pump pool heater or in a safe place for fu

w.c.) CFM Size 4 Size 5 Modulating Gas System The second system, the Maxitrol modulating gas system, consists of a temperature selector dial, a discharge air sensor, an amplifier, and a Maxitrol 14 modulating gas valve. The two types of Maxitrol systems used are the Maxitrol Amplifier14 series or the Maxitrol 44 series. The Maxitrol 14 utilizes a discharge air sensor and modulates the Maxitrol gas valve to provide discharge air to match the selected temperature on the temperature selector. The M

Refrigerant Low Pressure Control: Stops the com- pressor if refrigerant suction (low side) pressure falls too low as a result of a malfunction, loss of charge or extreme cold conditions. Indicator Lamps: There are 6 indicator lamps located on the unit control panel (see Fig. 3 below): • Power (amber lamp): When lit, indicates power is applied to the unit. • Water Flow (green lamp): When lit, indicates nor- mal water flow. • Heat Demand (green lamp): When lit, indicates the actual water temperatu

i. Assure that all system radiators, piping and vents are absolutely leak tight. • When a steam boiler is installed in an existing system, ALL air vents should be replaced at the same time. This assures that the new boiler will not be compromised by existing system leaks. • If the system contains hidden supply or return piping (hidden behind walls, buried in concrete, etc.) pressure test this piping to assure there are no leaks. ii. Repair any leaks in the system. iii. Install accurate water met

As with all heat pump pool heaters, compared to other types of heaters such as gas or oil-fired, this heat pump pool heater has lower heating capacity on a BTUH/hr basis. As a result, it will be required to operate longer to accomplish the desired results. It may, at certain times, operate as much as 24 hours per day. However, this should not be of concern to the owner, because the unit is designed to operate continuously. Even though it may operate continuously for many hours, it will still hea
