matches the reheat temperature set point.
Commissioning
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.
Operation and Maintenance
General
Immediately following unit startup, the air
conditioning system requires a maintenance
schedule to assure continued successful
operation. A maintenance program similar to
the example given below should be
scheduled for routine maintenance of this
equipment in order to provide efficient and
reliable operation for the owner.
Maintenance Schedule
One week after start-up:
Check refrigerant charge. Evacuate and
repair if leaking.
Check filters for cleanliness. Measure
pressure loss if applicable. Replace if
necessary.
Check cycling of compressors, fans and
valves. Correct unusual cycling.
Monthly:
Check cleanliness of filters, and replace if
necessary.
Check cooling coil drain pan to assure
proper drainage or correct.
Inspect evaporator and condenser coils.
Clean if dirty or obstructed in any way.
Quarterly:
Check operation of heating and cooling
sections.
Check inlet and outlet air temperatures.
Determine cause for abnormal changes.
