Safety Warning The purpose of this Service Manual is to provide sufficient information to allow a person with the skills as required by the controlling Regulatory Authorities to carry out effective repairs to a Rheem 310 series Heat Pump Water Heater in the minimum of time. Safety precautions or areas where extra care should be observed when conducting tests outlined in this manual are indicated by print in bold italics and/or a warning symbol. Take care to observe the recommended procedure.

Operation Operation – Water System: The heat pump utilises a form of heating called ‘top down’ heating. The circulator (1) draws cooler water from the bottom of the cylinder via the long dropper tube (2). The water passes through the heat exchanger (condenser) (3) where it is heated by the refrigerant and is then returned to the top of the cylinder via a short dropper tube (4).
Boost mode allows 220 litres of 60ºC hot water to be provided by electric boosting. During this mode the circulator will cycle on and off periodically allowing for the 220 litre boost capacity rather than just the amount of water above the element as is the case with a conventional electric boost system. Once a heating cycle is completed the error is cleared and normal operation is resumed on the next call for heat.

Refrigeration Terms and their Meaning Sub Cooled Liquid – A substance below its saturation temperature at a given pressure. Super Heated Vapour – A substance above its boiling point at a given pressure. Saturated Vapour – A substance at its boiling point at a given pressure. Latent Heat – Hidden (invisible) heat removed or added to a substance that results in a change of state (i.e. liquid to a vapour) without an increase or decrease in temperature.
Compressor - An electro-mechanical device that adds heats to the refrigerant by compressing it, known as “heat of compression” the resulting increase in refrigerant temperature increases its pressure and causes the refrigerant to circulate through the system. Evaporator - A finned copper coil mounted on top of the water heater. The refrigerant enters as a liquid, as it passes through the coil it absorbs heat from the surrounding atmosphere and “boils off” (evaporates) to a gas.
When first attending a call of this nature it is essential to establish the probable hot water usage by querying the usage habits of the household and compare this with the potential delivery of the model water heater installed. It can then be established if the usage is within or outside the capacity of the model. The areas to look at for excessive usage are: 1. Automatic washing machines. 2. Showers exceeding 12 litres/minute for mixed water and 5 minutes in duration. 3.
