gCheck the voltage at the compressor motorconnections. If the voltage is 5% below or 10% above the rated voltage or there is a d'dferencegreater than 3% between phases, shut down the system and call the power company. A failure to do so may cause damage to the equipment.

After the unit is in operation, it will take about 30 minutes runningtime to stabilize the system.

In order to check for a properlyworking system, it is recommended that a thermometer be placed in the-return air and one placed in the air supply. After all insulatingof ductwod_and adjustments of air registers are complete, a temperature difference of 15° to 20 ° is considered satisfactory.

°When the above steps are completed, a check of voltage and amperage should be made of all

motors. These readings should be within 10% of the performance ratings given for the specific ambients.

.

Suction and discharge pressures should also be checked to ensure that they agree reasonably well with the pressures shown in the catalog for the prevailing ambient conditions. Also, a suction superheat temperature of 20°F (10°F for units with scroll compressors) plus or minus 5 ° F is common for these units when the outdoor ambient is approximately 95°F. This should be used as a gauge in determining that the system is not overcharged or has lost some of its charge.

Finally, the thermostat should be checked out to assure proper operation. Literature packed with the thermostat and sub-base will provide information for this check out.

HEATING CYCLE CHECK-OUT

1.With the thermostat calling for heat and set at 10° above room temperature, engage disconnect switch(es) to start the system.

. All units are factory tested to assure operation of the defrost control system. The clock on the defrost control is factory set to check for defrost conditions every 60 minutes of unit operation.

The defrost control used in heat pumps has three possible time settings;30 minutes, 60 minutes, 90 minutes. This clock can be re-set to meet the needs of the area in which the equipment is installed. In areas where the winter temperatures are low, a 30 minute setting is recommended.

The heat pump is equipped with an electronic defrost control. This solid state defrost control

. operates in conjunction with an extemal sensor located at a "cold"spot on the outdoor coil. The control operates on a "Time/Temp" to initiate and "Temp" to terminate the cycle. The control will initiate a defrost cycle every 60 minutes (set by the factory) if the coiltemperature at the sensor is approximately 35"F or less. As the coil is being defrosted, its temperature will rise until it reaches approximately 65°F. At this point the sensor will terminate the defrost cycle. The entire process will take between one and three minutes. In areas where the air is generally moisture laden and frost is prevalent, the defrost interval time may be shortened from 60 minutes to 30 minutes by simply moving the jumper wire (see figure 3) from the "T2" pin to the "1"1". In the event of a failure of the sensor to open to terminate the defrost, the control has a built-in lr minute maximum defrost time, after which it will automatically end the defrost cycle.

Heat Pump specifications

Goetti Air Conditioning Heat Pump systems represent a significant advancement in climate control technology, offering efficient heating and cooling solutions for residential and commercial properties. These innovative systems are designed to provide year-round comfort while maximizing energy efficiency and minimizing environmental impact.

One of the main features of Goetti heat pumps is their advanced inverter technology. This system allows for variable speed operation, meaning the pump can adjust its output to match the heating or cooling needs of a space more precisely. This results in significant energy savings, as the system can operate at lower speeds most of the time, consuming less power while maintaining a constant temperature.

Moreover, Goetti heat pumps utilize eco-friendly refrigerants that adhere to the latest environmental regulations. This commitment to sustainability not only helps reduce the carbon footprint of the system but also ensures that users are compliant with existing and future environmental standards. The use of these refrigerants contributes to the overall efficiency of the unit, as they improve heat transfer and reduce energy consumption.

Another characteristic of Goetti heat pumps is their exceptional durability and reliability. Constructed from high-quality materials, these systems are designed to withstand various weather conditions, ensuring optimal performance even in extreme temperatures. The robust design not only extends the lifespan of the heat pump but also reduces maintenance costs, as fewer repairs are needed over time.

Goetti offers heat pumps in a range of sizes and capacities, making it easy for consumers to find the perfect fit for their specific needs. Additionally, many models come equipped with smart technology, allowing for remote operation and monitoring through mobile applications. This feature enables users to optimize their energy usage, set schedules, and ensure that their comfort needs are always met, regardless of their location.

The noise level of Goetti heat pumps is also commendable. With advanced noise reduction technologies, these systems operate quietly, ensuring a peaceful indoor environment. This aspect is particularly beneficial for residential applications, where noise can be a significant concern.

In summary, Goetti Air Conditioning Heat Pump systems are a testament to innovation in climate control technology. With their advanced inverter technology, eco-friendly refrigerants, robust construction, and smart features, they offer a reliable and efficient solution for heating and cooling needs. Emphasizing sustainability, performance, and user convenience, Goetti continues to lead the way in creating comfortable living and working environments.
