Helpful Hints & Operating Practices - Bard MULTI-TEC W18AAPA Service Instructions Manual

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.
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. Heat pumps, especially air-to-air heat pumps, may have the system (compressor) run
continuously at lower outdoor temperatures, and this is normal. The heat pump (compressor)
mode is controlled by the 1
outdoor temperature drops off, the heat pump mode heat will also diminish (because there is less
heat in the outdoor air to absorb), and must be supplemented by the 2
is not as efficient as the heat pump. The thermostat automatically controls everything, and the
backup electric heat will only operate on demand as needed to maintain the desired temperature.
7. 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
different 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.
8. Make sure you thoroughly understand how the heating and cooling system itself is intended to
operate and what to expect from it. Have your installer or Service Company explain and
demonstrate proper operation of the heating and cooling system.
