Niles said back where break room is cooling well. System was out on drain safety. Noticed vent on wrong side of trap on all units. Found that the only unit running was the big unit. Both other package units were out on drain safety. Condensate drain wasn't clogged. Checked configuration for Condensate switches. Called carrier tech support to verify configuration of unit is correct now. Determined Condensate switches are bad. Bypassed one and the other Condensate switch started working. All units are operational at this time. Need to return and replace both units Condensate switches and correct the ptraps on all units. Returned and replaced drain safety switch in package units (2). Tested units. Ran systems through cooling cycle. No alerts or faults present. Systems are working at this time.
Replaced client provided filter. Checked temp split and at optimal temps. Checked cooling functionality at thermostat and circuitry in air handler. Unit clean and operational. Checked pressures and charge via superheat, at 12 degree at good temp.
