About this file

This document consists of technical drawings and specifications for HVAC equipment upgrades at the Moss Avenue Pumping Station (MAPS), a project by the City of Santa Monica Water Resources Division in California. The primary equipment specified includes an outdoor condensing unit (Model TUHYE0964AN41AN) with a cooling capacity of 96,000 BTU/H and heating capacity of 108,000 BTU/H, paired with an indoor fan coil unit (Model TPEFYP072MH140A). The system operates on 460V, 3-phase, 60 Hz power for the outdoor unit and 208/230V, single-phase, 60 Hz power for the indoor unit. The mechanical plans detail equipment placement on both the ground floor and upper floor, with specific requirements for refrigeration line routing, condensate drainage with minimum 1% slope, ductwork configuration including supply and return air paths, and outside air intake specifications. Construction keynotes mandate contractor responsibility for insulation of all condensate piping, equipment support and seismic restraints per specifications, field verification of all dimensions and existing conditions, and coordination with the architect regarding final equipment locations and clearances.

The drawings specify multiple accessory kits required for the outdoor unit, including Big Foot stands, header kits, joint kits, low ambient kits, panel heater kits, and snow/hail guards. The indoor unit includes a drain pump, external heater adapter, and filter box with 4" MERV 13 filter. Refrigeration piping is sized at 3/8" for liquid lines and 7/8" for gas lines, with a maximum total line length of 3,280 feet and maximum distance between outdoor and indoor units of 541 feet. The system uses R410A refrigerant with an original charge of 21.0 lbs plus 9.0 oz. No pricing information, contract terms, bid deadlines, or award dates are contained within this technical specification document.
