Product Design

GPH Package Units are designed for outdoor installations only in either residential or light commercial applications.

The connecting ductwork (Supply and Return) can only be connected for horizontal airflow.

A return air filter must be installed behind the return air grille(s) or provision must be made for a filter in an accessible loca- tion within the return air duct. The minimum filter area should not be less than those sizes listed in the Specification Sec- tion. Under no circumstances should the unit be operated without return air filters.

A 3/4" pipe is provided for removal of condensate water from the indoor coil. In order to provide proper condensate flow, a drain trap is supplied and shipped loose inside the unit for field installation. (Do not reduce the drain line size).

Refrigerant flow control is achieved by use of restrictor ori- fices.

Package Heat Pump models use a combination of restrictor orifices and thermostatic expansion valves for refrigerant flow control.

Some heat pump models also have a suction line accumula- tor installed between the reversing valve and the compressor. The object of the accumulator is to:

1.Provide a liquid refrigerant storage vessel during prolonged system off cycles.

2.Store excess liquid refrigerant not needed by the system while running.

3.Return oil and saturated vapor to the compressor at a controlled rate.

4.Retain stored excess refrigerant during a sudden system pressure fluctuation such as seen in defrost cycles.

Refrigerant flow control is achieved by use of restrictor ori- fices. GPH units use the FasTest Access Fitting System, with a saddle that is either soldered to the suction and liquid lines or is fastened with a locking nut to the access fitting box (core) and then screwed into the saddle. NOTE: The core must not be removed from the saddle until the refrigerant charge has been removed. Failure to do so could result in property damage or personal injury.

The single phase units use permanent split capacitor (PSC) design compressors. Starting components are not required for these units. A low microfarad run capacitor assists the compressor to start and remains in the circuit during opera- tion.

The outdoor fan and indoor blower motors are single phase capacitor type motors. GPH1360H41* units have EEM in- door blower motors that are energized by a 24V signal from the IBR and are constant torque motors with very low power consumption. The EEM features an integral control module.

Air for condensing (cooling cycle) or evaporation (heating cycle) is drawn through the outdoor coil by a propeller fan, and is discharged vertically out the top of the unit. The out- door coil is designed for .0 static. No additional restriction (ductwork) shall be applied.

Conditioned air is drawn through the filter(s), field installed, across the coil and back into the conditioned space by the indoor blower.

Package Heat Pump indoor sections are designed to accept optional components such as auxiliary electric heaters and circuit breakers. Provisions for these components have been made at time of manufacture.

Location and Clearances

NOTE: To ensure proper condensate drainage, unit must be installed in a level position.

Outside Slab Installation - Horizontal (H)

NOTE: Roof overhang should be no more than 36" and provi- sions made to deflect the warm discharge air out from the overhang.

Minimum clearances are required to avoid air recirculation and keep the unit operating at peak efficiency.

GPH 13 H, Package Heat Pump Units specifications

Goodmans Package Heat Pump Units, specifically the GPH 13 H model, represent an advanced solution in residential and commercial climate control. Known for their efficiency and reliability, these heat pumps offer a combination of heating and cooling capabilities, making them ideal for year-round comfort.

One of the standout features of the GPH 13 H is its energy efficiency rating. With a SEER (Seasonal Energy Efficiency Ratio) of 13, it efficiently converts energy into heating and cooling, which can lead to significant savings on utility bills. This efficiency is not only beneficial for homeowners looking to reduce their energy footprint, but it also qualifies for many energy rebate programs.

Durability is another hallmark of the GPH 13 H. Built with robust materials, the unit is designed to withstand various weather conditions, ensuring longevity and reliable performance. Components are treated to resist corrosion, which extends the lifespan of the heat pump and enhances its efficiency.

The GPH 13 H utilizes innovative inverter technology, allowing it to adjust its cooling and heating output according to the space's specific needs. This results in more consistent temperatures and improved indoor comfort. Additionally, the variable-speed compressor operates at different levels, reducing energy consumption while providing effective heating and cooling.

In terms of installation, the GPH 13 H offers versatility. Its compact design facilitates easy placement in various locations, making it suitable for both new construction and retrofitting existing spaces. The unit's all-in-one design simplifies installation by minimizing the need for external ductwork.

Quiet operation is a critical consideration for many homeowners, and Goodmans excels in this area. The GPH 13 H is engineered to minimize noise levels, ensuring a peaceful indoor environment. This feature makes it an excellent choice for residential areas where noise may be a concern.

The unit also features advanced control systems, including programmable thermostats that allow users to set specific temperature schedules. This feature not only enhances user comfort but also contributes to energy savings by preventing unnecessary heating or cooling when spaces are unoccupied.

Overall, Goodmans Package Heat Pump Units, GPH 13 H, combine efficiency, durability, and advanced technology to deliver a reliable climate control solution. With its focus on energy savings, quiet operation, and flexibility in installation, this model stands out as a leading choice for those seeking optimal home comfort. Its thoughtful design and engineering make it a worthwhile investment in both residential and commercial settings.
