1 Air Conditioner Water Heater - A Product of HotSpot Energy LLC PLEASE READ THIS BEFORE YOU INSTALL THE UNIT 1. This air conditioner must be installed and/or repaired by a qualified technician. If you perform part of the installation yourself, you MUST have a qualified HVAC technician commission the unit. Commissioning includes inspecting the installation work and making all final electrical and refrigeration connections, evacuating the unit with a vacuum pump, releasing the R410a pre-charged refrigerant into the system, and starting up and testing the unit. If you have used a HotSpot provided 25 ft. line-set extension or have used a custommade line-set longer than the 25 ft. the technician will need to add oil and refrigerant per the installation manual instructions. YOU CANNOT COMMISSION THE UNIT YOURSELF. 2. The air conditioning unit must be grounded properly. 3. This unit contains a heat recovery water heating circuit. Make sure to leave the pump switch (located on the outdoor unit) in OFF position during the installation process until the water supply is connected and turned on. Do not allow the pump to operate without water flow. FAILURE TO OBSERVE THE ABOVE MAY DAMAGE THE EQUIPMENT AND VOID YOUR WARRANTY. Please read the SAFETY AND OPERATING INSTRUCTIONS carefully before operating the unit. Please respect the safety precautions when using your air conditioner to prevent fire, shock hazard, personal injury or death.
2 SAFETY PRECAUTIONS INSTALLATION AND OPERATION PRECAUTIONS Do not attempt to perform any work yourself that involves opening an equipment cabinet or that involves any refrigerant or electrical connections. You should only do part of the installation if you are qualified to do so. This may include mounting the outdoor unit on a pad and mounting the indoor unit, laying out and mounting the line-set, drain line, but not connecting the line-set to the indoor or outdoor units. You may also choose to lay out and run the electrical line from your power source to the system but do not connect the wiring at either end. You may also choose to run the water lines and connect them to the tank and to the unit if you are qualified to do so, if so please follow the instructions that are provided and make sure you perform the work in compliance with IAPMO and local plumbing codes. If you do part of the installation improperly, this may cause water leakage, water damage, refrigerant leakage, damage to the unit, electric shock, fire, injury or death. The unit should be installed by a qualified technician. ONLY A LICENSED HVAC TECHNICIAN CAN COMMISSION THE UNIT, AFTER FOLLOWING NORMAL INDUSTRY STANDARD PROCEDURES AND MAKING ALL ELECTRICAL AND REFRIGERANT CONNECTIONS, EVACUATING AND PROPERLY CHARGING THE SYSTEM. COMMISSIONING MUST BE PERFORMED ACCORDING TO ASHREA/AHRI STANDARD PROCEDURES AND LOCAL CODES. Please use a proper ground. Improper grounding could cause electric shock, fire or equipment damage. Do not place the ground line near water or gas pipes, electric or telephone lines. Do not install the unit in a place where there could be a gas leak. The unit may catch fire or cause an explosion if flammable gas leaks around it. This unit is not rated for operation in a hazardous environment..
3 Please ensure smooth flow of water when installing the drain hose. If the drain line becomes kinked or blocked you will likely suffer water damage. The indoor unit should be installed at least 7 ft. high from the floor. If the fuse on the PCB board is blown, please have it changed only by a Qualified technician. Do not operate with wet hands. Avoid staying directly in front of operating unit. Do not insert foreign objects into the unit. Always have the unit repaired by a professional technician. Danger of electric shock or fire if used improperly. Do not use if the power cord is damaged, it could cause an electric shock or fire. Do not allow children to operate the air conditioner. Never sit on the unit. If you notice an abnormality (burnt smell, etc) please shut the power off from the Breaker. The unit should not be used for any other purpose. Avoid spilling liquids on the unit. Do not place the air conditioner close to a heat source, it could cause a deformation or color fading. Do not block the air intake and outlet vents. Do not let the air conditioner function at maximum power for an extended period of time (close all doors and windows). Do not operate without the air filter installed or when the front intake grill has been removed. Do not place anything on the unit. Always turn the power off before cleaning the air conditioner to avoid any possible accidents. Please ensure proper ventilation when using the air conditioner.

14 5- WATER HEATING CIRCUIT 1. The water heating circuit can be enabled/disabled with a switch located on the outdoor unit. It is the only user accessible on-off switch on the outdoor unit. Be careful not to touch nearby electrical connections. Make sure you are wearing gloves and shoes and are not standing in a wet area when operating this switch. The switch must be off until the outdoor unit is connected to the water lines/water tank per the installation instructions and there is water pressure established in the water circuit with all air purged from the water lines. 2. The circulation pump is a water-cooled unit. Allowing the water heating circuit pump to operate without water will damage the circulation pump and void the pump warranty. If in the future you must shut off your water supply and/or drain your water tank, make sure to disable the ACWH water heating circuit first. Alternatively, you can turn off the circuit breaker that supplies power to the ACWH to keep the pump (entire system) from running during a water outage. 3. The water heating controls are automatic. The recovery circuit will run when there is sufficient heat available for heat recovery water heating. This means the water heating circuit will probably be active whenever the system is running. To verify operation of the water heating circuit, carefully and temporarily peel back a small amount of water line insulation at a point near the outdoor unit and verify that the return line is hotter than the supply line. 4. If your unit was ordered with (-HL) high temperature limit option, the water heating circuit will turn itself off whenever the tank temperature is above 140F. If you do not have this option, note that the water temperature may get as hot as 158F. If you do not have the HL option you must have a scald-valve (also called a mixing valve or tempering valve) installed on your water tank. WATER ABOVE 115F CAN SCALD. WATER AT 140F OR HOTTER CAN CAUSE SEVERE INJURY. A scald valve is recommended regardless of options installed. 5. If your system is equipped with Freeze Protection (option FP) you must make sure the outdoor unit has power, the freeze protection circuit cycles tank water to keep the outdoor lines and heat exchanger from freezing. This action relies on the pump, which requires electricity. IF YOU HAVE FREEZE PROTECTION AND DURING FREEZING WEATHER YOU HAVE A POWER OUTAGE, IT IS HIGHLY RECOMMENDED THAT YOU CLOSE THE ISOLATION VALVES AND DRAIN THE WATER HEATING CIRCUIT or connect the system to a backup power source. IF YOU DO NOT HAVE THE FP FREEZE PROTECTION OPTION, YOU MUST DRAIN THE SYSTEM IN ADVANCE OF ANY FREEZING WEATHER CONDITIONS. 6. The pump uses an easily replaceable cartridge that contains all of the moving parts. If it needs to be replaced please consult a qualified technician. Contact HotSpot for a replacement cartridge.

17 Main Specifications For Cooling & Heating The pump consumes 90w of power. However, when the pump is running, waste heat is being recovered which lowers the head pressure of the compressor and lowers the motor torque causing an electrical savings of ~120w. at full operation. The unit will have lower overall electrical consumption when the heat recovery circuit is active, with no negative effect on cooling performance.
