Electric Heating:
1. Turn the unit power on.
2. Turn the unit blower on, and check for correct
rotation.
3. If correct, take blower amp readings, and
compare to see if the amp draw is within the
safety factor area of the motor. Once correct,
turn blower off.
4. Turn on the first stage of heating.
5. Check amp draw of each element of each
stage.
6. Ensure blower started with heat.
7. Check temperature rise across heating section
while all stages are on.
8. If temperature rise is within range, turn all
heating calls off.
9. Check to see that blower stops.
Optional Equipment
Operation of each of the following, if equipped in the
unit, must be checked according to that item’s
manufacturer’s specifications:
− Clogged filter switch
− Supply air smoke detector
− Return air smoke detector
− Modulating Hot gas reheat
− Hot gas bypass
Commissioning
The commissioning of an HVAC system is the process
of achieving, verifying, and documenting the
performance of that system to meet the operational
needs of the building. This may not be a formal
process in smaller structures, such as a normal
residence, but some form of owner acceptance will
occur. Adjustments made during the commissioning
phase may include air balancing, or configuration of
controls, and operational sequences.
Air Balancing
High performance systems commonly have complex
air distribution and fan systems. Unqualified personnel
should not attempt to adjust fan operation, or air
circulation, as all systems have unique operating
characteristics. Professional air balance specialists
should be employed to establish actual operating
conditions, and to configure the air delivery system for
optimal performance.
Water Balancing
A hydronic specialist with a complete working
knowledge of water systems, controls, and operation
must be employed to properly balance the entire
system. Unqualified personnel should not attempt to
manipulate temperatures, pressures, or flow rates, as
all systems have unique operating characteristics, and
improper balancing can result in undesirable noises
and operation.
Controls
A variety of controls and electrical accessories may be
provided with the equipment. Identify the controls on
each unit by consulting appropriate submittal, or order
documents, and operate according to the control
manufacturer’s instructions. If you cannot locate
installation, operation, or maintenance information for
the specific controls, then contact your sales
representative, or the control manufacturer for
assistance.
Do not alter factory wiring. Deviation from the
supplied wiring diagram will void all warranties,
and may result in equipment damage or personal
injury. Contact the factory with wiring
discrepancies.
