Johnson Controls HMCG2 Series User Manual

Note: Operation below listed temperatures is
permissible for a short period of time during
morning warm-up.
If the main power supply to the outdoor and indoor units
is off, place the system into operation as follows:
1. Enable the mode of operation.
2. Set the thermostat to the required temperature.
- Cooling: For cooling, the higher the setting,
the lower the amount of energy consumed.
Federal guidelines recommend a setting of
78°F (26°C).
3. Set the mode of fan operation required.
Power failure
If a power failure occurs, the system automatically
resumes operation when power is restored, using the set-
points that were present when power was interrupted.
When accidents, wind, storms, or other issues disrupt
electrical power supply to your home, set the thermostat
to the Off position.
Electronic thermostat
This computerized electronic thermostat, when
programmed, functions automatically to operate the
system as follows:
• When the indoor temperature rises above the higher
(cool) setting, the outdoor unit operates and the
indoor fan circulates the cooled, filtered air. When
the room temperature is lowered to the selected
level, the system shuts off. The indoor fan either
shuts off or runs continuously, depending on the
selected fan switch setting.
Operating efficiency
For the most efficient operation, keep storm windows and
doors closed all year long. They help insulate against heat
and cold, and they also keep out dirt, pollen, and noise.
Cooling conservation
The following are some useful points to note:
• To comfortably cool your home, your air conditioner
must remove both heat and humidity. Do not turn
your system off, even if you are away all day. It
is normal for this unit to run continuously as it
maintains the comfort level.
• Keep windows closed after sundown. While the
outdoor temperature at night may be lower than
indoors, the air is generally loaded with moisture
that is soaked up by furniture, carpets, and fabrics.
This moisture must be removed when you restart
your system.
• The hotter the outside temperature, the greater the
load on your system. As a result, do not be alarmed
when your system continues to run after the sun
sets on a hot day. Heat is stored in your outside
walls during the day and continues to flow into your
home for several hours after sunset.
• Use your kitchen exhaust fan when cooking. One
surface burner on high requires one ton of cooling.
Turn on your bathroom exhaust fan while showering
to remove humidity. However, exhaust fans must
not run excessively as this decreases efficiency by
removing conditioned air.
• Aid your system in the summer by closing drapes or
blinds and by lowering awnings on windows that get
direct sunlight.
System maintenance
Perform regular periodic preventative maintenance
on this equipment. The person most familiar with the
equipment in your HVAC system is a dealer. The dealer
can ensure your maintenance program meets the
conditions of the warranty, maximize the efficiency of
the equipment, and service your unit within the federally
mandated guidelines with regard to unlawful discharge of
refrigerants into the atmosphere.
Coil care
Keep the outdoor unit free of foliage, grass clippings,
leaves, paper, and any other material that may restrict
adequate airflow in and out of the unit. Vacuum the coil
to remove any debris from between the fins. If the coil
becomes excessively dirty, set the main disconnect switch
to Off and wash the coil with your garden hose. Avoid
getting water into the fan motor and control box. Flush
dirt from the base pan after cleaning the coil.
Service calls
There are a few instances where you can avoid
unnecessary service calls. If the unit stops functioning
correctly, check the following items before calling your
servicing dealer:
• Indoor section for dirty filter
• Outdoor section for leaf or debris blockage.
Eliminate the problem, set the thermostat to the
Off position for 10 s, and then select the heating or
cooling mode of operation to restart. The system
starts after the 5 min anti-short-cycle delay. If the
system does not start, call your service dealer.
WARNING
Your system contains environmentally friendly
refrigerant R-410A, which operates at high pressures.
You may be in danger if you try to make an attempt to
repair your unit. Please contact your local dealer.
Filter care
Inspect the air filters at least once a month. If they are
dirty, wash reusable filters with a mild detergent in
accordance with the manufacturer’s recommendations.
Replace disposable filters with new filters. Install the clean
filters with the airflow arrow in the same direction as
the airflow in your duct. Filters must be clean to ensure
maximum efficiency and adequate air circulation.
