Zorro HVAC Mechanical Inspection August 22 -24, 2012 On Wednesday, August 22, 2012 I arrived at Zorro Ranch to inspect the condition of the HVAC system to review preventative maintenance and repairs made by JB Henderson and to evaluate the BMS filet 2000 control system. The following is a list of systems and equipment that were checked and recommendations for upgrades. I. Marley Cooling Tower: Found corrosion on air intake metal enclosures, water sump and sump housing with elevated levels of corrosion all surfaces need to be re coated, the fill membrane which is the original to the towers installation needs to be replaced due to excessive mineral deposits. The tower spray header and spray nozzle should be repaired to assure proper water flow on fill membrane. I will contact JB Henderson to provide a proposal for this work. 2. Pool Pack Unit: The pool pack unit form the original installation was undersized for the pool room area, due to electrical restrictions this unit was the largest single phased unit available at the time. This unit has had to overwork to keep the humidity in the pool area in range due to insufficient air flow from the unit to the overhead air grills and floor air diffusers. The way pool pack is designed to work it washes two of the largest wall spaces on both sides of the pool with a curtain of dry dehumidified air and also pool water is piped into the unit for heat removal and to help preheat the pool water. The pool water was never piped and connected to the pool pack unit. In the past few months the pool pack has experienced many mechanical and electrical problems due to many power dips, power outages, and the inadequate original design. Manolito and Wendy have had JB Henderson replace the system compressor, main electrical circuits, and refrigeration expansion valves to keep the current unit operational. On my visit I have found additional operational issues with the pool pack — no discharge air from the unit is ent
