Page 10: Working Principle
II. Working principle This heat pump water heater gathers heat from the environment (refrigerant-to-air HXR), compresses refrigerant vapor to a higher temperature, then heats the working fluid (domestic water or glycol depending on the application) in the condenser section (refrigerant-to-water HXR). The condensed high pressure and warm fluid is rapidly expanded through the EEV to introduce cold liquid into the evaporator (ambient air side) to be boiled off and complete the circuit. -

4.3. Installation requirements A means of isolating the unit from the main system flow is required for service. A bypass value is recommended to allow the system piping to be cleaned without introducing sediment into the heat pump heat exchangers. Install a 40 mesh or finer filter near the inlet of the unit. -

Page 20: Unit Operation
Operational guideline： To drain the system, first isolate the supply and return piping to the unit, then ensure the internal isolation valves on each heat exchanger are open, next open the drain port at the bottom of inlet water pipe to drain the water from the system. Opening the air vent on the return piping will speed up the draining process. - Page 21 The heat pump has three modes of energy level adjustment when it is running. The principle is to calculate the load required by the system based on the current temperature of the water tank and the set temperature, so as to turn on the corresponding number of compressors.
- Page 22 Main functions Note: The following description is for reference only, please refer to the latest version of the program for specific function parameters. 1. Defrosting When the outdoor temperature in winter is below 32F (0°C) and the evaporator temperature is lower than the dew point temperature of the ambient air, condensation will occur on the surface of evaporator.
- Page 23 For multiple water heater installations, there are three methods of controlling the system A) Ice Air Control Board (controls up to 16 units) B) Ice Air Sequencing Software (requires computer to run software and RS485 communication wire; controls up to 16 units)

VI. Electrical wiring diagram 1. Notice • The power supply voltage must conform to the rated voltage. • Wiring must be carried out by a professional and wired in accordance with wiring diagram. • Ensure the power supply wires are properly sized and protected from excessive current (please refer to the performance specification and parameters table for details). - Page 25 • Always disconnect the power prior to opening the electric cabinet. • Workers must wear anti-static gloves during electrical operation. Do not insert hand or foreign matter into the outlet of the water heater. It is forbidden to refit the unit and change the parameters of the unit without permission.
