!WARNING

THIS UN IT MUS T BE PERMA - NENTLY GROUNDED. A GROUND LUG IS PR OV IDE D NEAR THE CO NTA CTOR FOR A GR OUND WIRE. FAILURE TO DO SO CAN CAUSE A FIRE OR ELECTRICAL SHOCK RESULTING IN PROPER- TY DAMAGE, SEVERE PERSON- AL INJURY OR DEATH.

VIX. WIRING

NOTE: Field wiring must comply with the National Electric Code (CEC in Canada) and any local ordinance that may apply.

X. ELECTRICAL POWER

It is important that proper electrical power is available at the unit. Voltage must not vary more than 10% of that stamped on the rating plate. (See Electrical Data Table for mini- mum and maximum voltage.) Interphase voltage variation on three-phase units must not be more than 3%. Contact local power company for correction of improper voltage or phase unbalance.

IMPORTANT: Models equipped with scroll compressors must be phased correctly for proper compressor rotation. If the compressor is noisy or if suction and discharge pres- sures do not appear normal, reverse any two power leads to the unit. Extended run time in reverse rotation will damage the compressor and lead to premature failure.

XI. POWER WIRING

Power wiring must be run in grounded rain-tight conduit. Power wiring must comply with the National Electric Code (C.E.C. in Canada) and any applicable local code.

XII. WIRE ROUTING

POWER WIRING MUST BE RUN IN CONDUIT. Conduit must be run through the con- nector panel below the service cover and attached to the bottom of the control box.

If low (extra-low in Canada) voltage control wire is run in conduit with power supply, Class I insulation is required. If run separate, Class II is required. Low voltage wiring may be run through the insulated bushing provided in the 7/8 " hole in the connector panel then routed to the control box.

!WARNING

AFTER COMPLETION OF WIRING CHECK ALL ELECTRICAL CONNEC - TIONS, INCLUDING FACTORY WIRING WITHIN THE UNIT, AND MAKE SURE ALL CONNECTIONS ARE TIGHT, REPLACE AND SECURE ALL ELECTRICAL BOX COVERS AND ACCESS DOORS BEFOR E LEAVING UNIT OR TURNING ON POWER TO CIRCUIT SUPPLY UNIT. FAILURE TO DO SO CAN CAUSE A FIRE OR ELEC TRICAL SHOCK RESUL TING IN PROPERTY DAMAGE, PERSONAL INJURY OR DEATH.

XIII. GROUNDING

A grounding lug is provided in control box for a ground wire.

Grounding may be accomplished by grounding the power line conduit to the unit.

XIV. THERMOSTAT — 61⁄2 AND 71⁄2 TON

A single-stage cooling, two-stage heating (if heating is used) thermosta t should be mounted on an inside wall about four to five feet above the floor in a location where it will not be affected by the sun or drafts, from open doors or other sources. Install, level, and after installation check the thermostat calibration and recalibrate if necessary.

XV. LEAK TESTING

Pressure line set and coil through service fittings with dry nitrogen to 150 psig maximum. Leak test all joints using liquid detergent. If a leak is found, relieve pressure, repair and retest.

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.
