Johnson Controls HMH7 Series User Manual

• The hotter the outside temperature, the greater the
load on your system. Therefore, 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 could 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 per 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.
Clearances
The minimum clearances from the outdoor unit shown
in Figure 1 must be maintained if any patio or yard
improvements are done around the outdoor unit.

location
Parts information
Replacement parts are available from your local
contractor or dealer.
Extended warranty
Special warranty packages (called performance promise
plans) are available through your contractor. These
packages reduce the potential cost of service calls
following the first year of operation on your cooling (or
heating and cooling) system.
Some efficiency dos and do nots
• Do not constantly adjust the thermostat. Adjusting
your thermostat setting does not make your system
heat or cool any faster. Set your thermostat to a
comfortable setting and only adjust it when required.
• Do not restrict air circulation. Placing furniture, rugs,
and other obstacles where they interfere with air
vents makes your system work harder to achieve a
comfortable temperature level. This requires more
energy, which means greater energy costs.
• Do not locate lamps or other heat-producing
appliances (radios, TVs, heaters) near your thermostat.
The heat from these items gives your thermostat false
information about the temperature in the room.
• Do select a comfortable thermostat setting, but keep in
mind that moderation in temperature selection saves
energy.
• Do turn on your kitchen exhaust fan when cooking
and your bathroom exhaust fan when showering. Also,
make sure your clothes dryer is properly vented. If
these items are neglected, excess heat and humidity
may be created, causing your air conditioning system
to run longer.
