_____Review operations and maintenance logs for major equipment
each operational visit. Make necessary adjustments and provide recommendations
to assure optimum equipment operation.When possible, operate one
boiler, chiller, or compressor at 90% capacity instead of
two at 45 % capacity.
_____Verify chiller refrigerant is clean and maintained at correct
charge level, air is kept out of chiller, condenser and chill water
temperatures and flows are maintained at optimum levels, tube surfaces
are regularly cleaned, and operating conditions are regularly logged.
_____Verify boilers are maintained and operated to assure proper
O2 trim, operating temperatures, flue damper, shell insulation, scale,
and operating logs.Verify pipes and tanks are insulated.Verify pipes,
steam traps, packing glands, valves, rings, orifices, gaskets, couplings,
and impellers have no leaks and are well maintained. Verify strainer
screens on pump systems are clean.
_____Verify pump motors and drives
are lubricate and properly aligned.
_____Verify air separators are operating properly and there is no
air entering the system.
_____Verify water systems are flushed.
_____ Verify proper water treatment procedures are used to reduce
fouling of transfer surfaces and the potential for biological growth.
_____ Check cooling tower bleed-off to ensure that water and chemicals
are not being wasted.
_____Verify gauges and thermometers are accurate.
_____Verify water side economizer systems are properly maintained
and operated.
_____Verify tubes and other heat-exchange surfaces are regularly
cleaned.
Mallory & Evans Service performs energy saver tasking that was
developed using tasking from EPA’s Energy Star Program and other
industry sources.The EPA’s Energy Star Buildings Program incorporates
preventive maintenance as part of a "Building Tune-Up to make
buildings more energy efficient through maintenance activities.This
checklist is very effective, with potential savings reaching 15% of
annual energy costs
