PERIODIC MAINTENANCE
Periodic maintenance must be conducted on your system to ensure maximum performance, especially
during peak operating periods and conditions.
1. Keeping the air filters clean is a key element. These are user responsibilities, either all or at
least in part, and if they cannot be fulfilled by the user, arrangements should be made with your
Service Company.
2. There is a condensate drain system for all heat pumps, and this must be kept open and free to
convey the condensate generated by the operation of the equipment to a suitable location,
(typically an internal drain). Depending upon the specific installation, the user would at least be
aware of the drain mechanism and know what to expect. If any questions, it should be reviewed
and discussed with your installer and/or Service Company.
3. All heating and cooling systems should have periodic inspections made by a trained professional,
who has the experience, knowledge, training, licensing, certifications, and the necessary tools
and equipment required to do these tasks properly and in accordance with approved or mandated
procedures.
4. The maintenance procedures and frequency of routine service can vary depending upon actual
type of equipment in use, type of building or facility, and other factors that can impact how often a
machine must be serviced.
5. Proper and routine maintenance and service will protect your investment and help extend the
service life of the product, and also help ward off more extensive and expensive repairs.
6. An open loop or well supplied water system may require special review by your system installer.
Check with installer for any special water system requirements.
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 the air filters.
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.
