GREENPAC™ AIR CONDITIONERS
MODELS AVGA
GENERAL DESCRIPTION
The GPac wall mounted air conditioner with gas heat is designed for use on a variety of applications including modular classrooms, relocatable offices and a multitude a permanent buildings. The GPac unit is manufactured in two cabinets with nominal cooling capacities of 2, 2-1/2, 3, 3-1/2, 4, and 5 tons and input heating capacities of 45,000; 67,500; 75,000; 90,000; 100,000 and 125,000 BTUHs.
The Marvair GPac is available with a number of factory and field installed options and accessories that permit the user to optimize the unit for specific applications.
MODEL AVGA:
EER: 9.0 - 9.6 with 80% Heating Efficiency
Cooling Capacities: 2, 2-1/2, 3, 3-1/2, 4, and 5 tons and input heating capacities of 45,000; 67,500; 75,000; 90,000; 100,000 and 125,000 BTUHs
SAFETY LISTED AND ENERGY CERTIFIED
All GPac air conditioners are built to the current UL and CAN/CSA standards. The units are listed by ETL and tested to the American National Standard/CSA Standard for Gas Fired Central Furnances; ANSI Z 21.47 -2006/CSA 2.30-2006. For energy efficiency and performance, the units are tested and rated in accordance to the current ANSI/AHRI (Air-Conditioning Heating and Refrigeration Institute) Standard 390 (Single Package Vertical Units). All AVGA units meet or exceed the efficiency requirements of ANSI/ASHRAE/IESNA 90.1.2010. GPac air conditioners are commercial units and are not intended for use in residential applications.
ECONOMICAL GAS HEAT
Factory set up for natural gas with easy conversion in field to propane
Natural gas high altitude pressure switch kit allows operation in sites from 6,000 to 10,000 ft. (1,830 m to 3,050 m)
Propane high altitude pressure switch kit allows operation in sites from 6,000 to 10,000 ft. (1,830 m to 3,050 m)
Vertical vent pipe kits
EASE OF INSTALLATION
Sloped top with flashing sheds water eliminates need the need for a rainhood
Built-in full length mounting flanges facilitate installation and minimizes chance of water leaks
Electrical knockouts on back and side
Gas connection on the right hand side
Factory installed disconnect
BUILT-IN RELIABILITY
High and low pressure switches with lockout relay protect refrigerant circuit
Time delay/anti-short cycle timer and low ambient control
PATENTED TUBULAR HEAT EXCHANGER WITH INTEGRAL FORMED DIMPLE TURBULATOR
Enhanced heat transfer for optimum efficiency
Quiet – eliminates noise caused by expansion and contraction of internal baffles
PATENTED INSHOT GAS BURNERS
Quiet, clean burning gas inshot burners fire in a direct line with the orifice and the tube
Unique carryover design (cross lighting from one burner to another) for immediate lighting
Optional stainless steel burner
DIRECT SPARK IGNITION CONTROL SYSTEM WITH LED FLASH FAULT INDICATOR
Thirty second purge of heat exchanger prior to ignition
Three ignition trials before lockout
Sixty second post purge at end of operating cycle prevents nusaince trips of rollout switch
One hour automatic reset after lockout – eliminates need to manually recycle on lockout
LED identifies operating status and simplifies service by flashing fault code
EASE OF SERVICE
Compressor and electrical box are easily accessible
Refrigerant access values allow quick check of refrigerant pressures
Easily accessible filter
LED identifies operating status and simplifies service by flashing fault code in heating mode
Copper tube, aluminum fin evaporator and condenser coils
