Zorro HVAC Mechanical Inspection November 19th — November 22, 2013 On Tuesday, November 19, 2013 I arrived at Zorro Ranch to inspect the condition of the HVAC system and review the proposed repairs in progress with Trane Corporation and ECI Controls. I also worked in conjunction with Brice Gordon and performed system wide operational checks of all of the heat pump units. The operational checks included heating and cooling compressor cycle operation, primary heating and secondary heating sequencing through ECI control program on the BMS system. Mechanical checks of all heating reheat coils and Belimo of valve actuators (for reheat control valves). Operational checks of all main system loops, cooling towers, heat pump condenser water and reheat hot water boiler, and Muller flat plate heat exchangers HE#1 and HE #2. We also performed purging of air out of all reheat heating coils on all heat pump systems. The following is a list of work in progress that needed to be addressed reported by Brice Gordon and repaired by Trane and ECI and also operational checks performed by Brice Gordon and I. I. Florida heat pump units — performed operational control sequencing checks air purging on reheat coils for HP 1 &2, 3, 4, 5, 7a, 7b, 7c, 7d, 8, 9, 10a, 10b, II, 12a, 12b, 12c, 12d, and 12d1. 2. Worked performed by ECI Controls HP - 3 - Belimo actuator replacement. HP — 4 — Heating coil replacement. HP — 10a — made adjustment to reheat actuator. 3. Work performed by Trane Corporation (Mechanical Repairs). HP — 3- Freon added due to coil freezing up. HP #5 (Exercise Room) Installed new compressor. HP — 7a — Replaced low pressure refrigerant switch and heating coil three way valve and actuator. The ECI Control technician performed repairs and checked the control system before my arrival. The ECI technician instructed Brice Gordon on Belimo valve actuator replacement. The Belimo valve actuator is a LRB-24SR. This valve operates and modulates 24 hours a day c
