System Pressures
Technicians with R-22 experience will need to become familiar working with high and low
side pressures that are much higher when using R-410A. A typical R-22 system operates
normally with a high side pressure of approximately 260 psi @ 120°F condensing
temperature and a low side pressure of approximately76 psi @ 45°F evaporator
saturation temperature.
A normally operating R-410A system with the same condensing temperature of 120°F and
45°F evaporator saturation temperature will have a high side pressure of approximately
500 psi and a low side pressure of approximately 150 psi.
• 5/16” socket or drive
• 1/4” socket or drive – Ground screws and control assembly use 1/4” machine thread screws
• 3/8” socket or drive – For outdoor fan blade removal
• 4 mm Allen wrench – For indoor fan blade removal
• Volt Ohm Meter
• Amp probe
• Needlepoint meter leads
• Sealed system and R-410A recovery equipment
• Thermal paste (Part #: WX5X8927)
• Extension needed for condenser shroud screws

Zonelines are packaged room air conditioners that provide cooling and heating for residential and
commercial properties. Available in 7,000, 9,000, 12,000 and 15,000 BTU models. Accessories are available to
duct conditioned air into an adjoining room.
The newly designed Zonelines are dimensionally the same size as older models and will ¿t into existing wall
cases.
Operation is similar to previous models, but with a totally new electrical and mechanical design.
Features
Example of features of a AZ65H09DAM with Make-up Air Module:
• Make-up Air: Supplies 35 CFM of continuous, conditioned fresh make-up air
• Cooling Capacity: 9,100 BTU @ 230 volts – 8,800 BTU @ 208 volts
• Energy EȺciency: 11.0 EER, on average over 8more eȻcient than other brands
• Dehumidi¿cation: Conditions incoming air above 55% relative humidity
• Reverse Cycle Heat: 8,300 BTU @ 230 volts – 8,100 BTU @ 208 volts
• Heat Pump EȺciency: 3.7 COPS
• Quiet Operation: Baked on mastic, cross Àow blower and two DC fan motors
• Heat and Freeze Sentinels: Prevents room from overheating or freezing
• Boost Heat Option: Provides supplemental resistance heat during heat pump mode
• Electronic Temperature Limiting: Prevents over cooling or over heating of room
• Electronic Touch Controls: Tactile buttons with LED display

For both AZ4500 and AZ6500, once the compressor
comes on in cooling, it will pull the room
temperature down to the thermostat setting.
Fan pulsing for temperature checking after
compressor shut-oȹ Zhen not in Class 2 mode:
• The Zoneline will pulse the indoor fan
periodically when it is not on a remote
thermostat and set to cycle cooling.
• The system will wait 6 minutes after the
compressor shuts oȺ, then pulse the indoor fan,
pulling air across the air sensor for a duration of
30 seconds.
• Should the ¿rst 2 minute pulse not activate the
Zoneline, the system will continue pulsing until
cooling is needed.
• Each pulse of the fan is running at low speed, no
matter what setting the user has chosen.
Operation
Cooling
AZ4500 In the cooling mode, the compressor,
indoor fan and outdoor fan run.
AZ6500 In the cooling mode, the compressor,
indoor fan and outdoor fan run,
the reversing valve is energized
throughout the entire cooling cycle.
Heating
AZ4500 In the heating mode, AZ4500 will
utilize the built-in resistance heater,
running with the indoor fan at one of
two speeds determined by the Fan
Speed selection.
Resistance heater output is not determined by
software. It is determined by hardware (power cord
amperage rating).
Temperature control in the heating mode is done by
cycling the resistance heater under control of the
room air sensor, or the room thermostat (if in Class 2
Mode).
Whenever the room temperature is 1.8°F below
the temperature setting, the control will energize
the heating cycle and remain in operation until the
room temperature reaches the temperature setting.
At this point, the Zoneline will turn oȺthe heating
cycle.
