BACKGROUND INFORMATION: The air conditioning rooftop unit that services the South Electric Building at White Slough Water Pollution Control Facility (WSWPCF) failed the week of June 15, 2015. The South Electric Building houses nearly the entire WSWPCF motor control center (MCC). If the MCC is not maintained in a cool environment, the motor controls will overheat and fail causing the equipment they control to fail. The air conditioning unit's failure was diagnosed as burned and corroded compressor coils resulting from age and corrosion. The failure caused the unit to stop cooling and is consistent with the unit's declining performance over the past several seasons. The unit was installed in 1990 and was the original air conditioning equipment in the building. A new air conditioning unit was special ordered from Industrial Commercial Refrigeration (ICR) that is currently under contract with the City for maintenance and repair of heating, ventilation and air conditioning equipment at various City facilities. The purchase and installation cost of the new unit is $12,460. The City Manager approved the emergency purchase without formally bidding the work due to the emergency condition. ICR was issued a purchase order for the new equipment June 17, 2015. Installation is planned for late August. WSWPCF purchased a portable air conditioning unit for use at the MCC until the new unit is installed. The portable air conditioning unit was purchased for $2,799 in lieu of renting a temporary unit at a cost of $1,150 per month. The portable unit will be available for use at other locations within the City in the future should the need arise. Purchase of the new air conditioning unit was paid from WSWPCF Operating Funds (53053003.72534). FISCAL IMPACT: Not applicable. FUNDING AVAILABLE: Not applicable. F.

The existing unit continuously leaks from brazed joints and this caused the compressor to operate without oil pressure and fail. The leaks are caused by the surrounding air environment. The new Trane unit will have specialized coating on all copper pipe and fittings. This will eliminate leaks cause by the surrounding air environment. *Please note unit lead time to ship is 6-8 weeks due to special coatings.
