HELPFUL HINTS AND

GOOD OPERATING PRACTICES

The following information will help you enjoy the full comfort and benefits of your Bard cooling and
heating system, maximize the performance and efficiency, and help extend the life of your system:

1. Always keep the equipment in peak operating condition with routine scheduled maintenance,

especially for the air filters and to assure clean outdoor coil.

2. For most efficient operation, set the thermostat at the temperature you prefer, and then let it take

control.  If any changes to the settings are required, they should be made in small adjustments
and the system be allowed time to respond.  Rapid changes either up or down should not be
done.

3. Setting the thermostat very high does not make the system heat faster, and setting it very low

does not make it cool faster.

4. It is not recommended to turn the system “Off” and then back “On” when you need it.  This can

allow temperature and humidity to build up in warm weather conditions and force the system to
run continuously to try and catch up.  If the building is to be unoccupied for a lengthy period, it is
best to adjust the thermostat to a reasonable higher (or lower depending upon the season)
setting rather than turning it completely off.  Upon return, the inside conditions will not be totally
out of control, and recovery time to desired conditions would be much shorter.

5. Keep all supply registers open and all returns free and unrestricted.  The heating and cooling

system is designed to have a certain amount of airflow for proper operation.  Therefore, closing
off registers, in unused rooms as an example, could reduce airflow below acceptable levels and
should not be done without review by your Service Company who can access the overall situation
and advise you accordingly.

6. The thermostat is the user’s primary connection to the system, so it is very important to have a

thorough understanding of how it works and how to use it properly.  Since there are many dif-
ferent types of controls available, and can vary depending upon what type of heating/cooling
system you may have.  Have your installer or Service Company explain and demonstrate proper
operation of the controls.
