C. ORDER PARTS

When reporting shortages or damaged parts, or when ordering repair parts, give the complete unit model and serial numbers which are stamped on the Unit Rating Plate.

D. STANDARD ITEMS

The condensing unit consists of a completely assembled package which includes a com- pressor, a condenser coil, fan, fan motors, outdoor control box, factory wiring, factory tubing and fittings.

E. INSTALLATION GENERAL

NOTE: These units must be installed outdoors. No ductwork can be attached, or other modifications made, to the discharge grille. Modifications will affect perfor- mance or operation.

The condensing unit should be installed outdoors. It should be located as near as possi- ble to the evaporator section to keep connecting refrigerant tubing lengths to a minimum. The unit must be installed to allow a free air flow to the condenser coils.

If several units are installed adjacent to each other, care must be taken to avoid recircu- lation of air from one condenser to another. In all installations, adequate space must be provided for installation and servicing.

The unit must not be connected to any duct work. Do not locate unit under a roof drip; if necessary, install gutters, etc., to prevent water run-off from hitting the unit. To prevent air recirculation, it is recommended that the unit not be installed under an overhang, but if necessary allow a minimum of 60 inches above the unit for air discharge.

NOTE: To prevent the possibility of freeze damage, you can install an air proving switch in the air handler supply duct wired in series with the compressor contactor coil (24V) which would lock out the compressor in the event of air flow failure.

F. ROOFTOP INSTALLATION (REFER TO FIGURE 4)

If rooftop installation is required, make certain that the building construction is adequate for the weight of the unit. (Refer to physical data chart.) Before placing the unit on the roof, make certain that the nylon rigging slings are of sufficient length to maintain equilib- rium of the unit when lifting. Under no circumstances should the unit be lifted by only one corner for rooftop installation.

G. SLAB INSTALLATION

Condensing units should be set on a solid level foundation. When installed at ground level, the unit should be placed on a 6 inch cement slab. If the pad is formed at the installation site, do not pour the pad tight against the structure, otherwise vibration will be transmitted from the unit through the pad.

R-410A specifications

The Heat Controller R-410A is an advanced refrigerant used in various heating and cooling applications, particularly in residential and commercial air conditioning systems. Recognized for its efficiency and eco-friendliness, R-410A has become a popular choice among HVAC manufacturers and professionals.

One of the main features of R-410A is its high efficiency. It operates at a higher pressure than traditional refrigerants, which allows it to transfer heat more effectively. This results in improved energy efficiency ratings (SEER and EER) for systems utilizing R-410A, leading to lower energy bills and reduced environmental impact.

R-410A is also known for its environmental sustainability. Unlike its predecessor, R-22, R-410A has zero ozone depletion potential (ODP) due to its composition of hydrofluorocarbons (HFCs). Although it does have a global warming potential (GWP), the advancements in technology have made R-410A a more environmentally friendly option compared to many older refrigerants.

Developed through innovative technological advancements, R-410A systems often incorporate variable speed compressors and efficient heat exchangers. These technologies allow for better modulation of cooling and heating outputs, ensuring that the indoor environment remains comfortable while using the least amount of energy possible.

Another significant characteristic of R-410A is its compatibility with a wide range of HVAC equipment. Many new air conditioning systems are designed specifically to use R-410A, which has led to the creation of a robust market for these units. Additionally, R-410A systems tend to require less maintenance and have longer lifespans compared to those using older refrigerants.

Safety is another consideration for R-410A users. While R-410A is non-toxic and non-flammable, technicians who work with this refrigerant need to be trained and certified due to its high-pressure properties. Proper handling and installation are crucial to ensure system efficiency and reliability.

In summary, the Heat Controller R-410A stands out in the HVAC industry for its efficiency, environmental benefits, advanced technologies, and compatibility with modern systems. As the industry continues to evolve, R-410A remains a key player, paving the way towards more sustainable and efficient heating and cooling solutions.
