Carrier 17/19EX - Manual (Page 138)

Check Optional Pumpout Compressor Water Piping
If the optional storage tank and/or pumpout system are installed, check to ensure the
pumpout condenser water has been piped in. Check for field-supplied shutoff valves and
controls as specified in the job data. Check for refrigerant leaks on field-installed piping.
Check Relief Devices
Be sure that relief devices have been piped to the outdoors in compliance with the latest
edition of ANSI/ASHRAE Standard 15 and applicable local safety codes. Piping connections
must allow for access to the valve mechanism for periodic inspection and leak testing.
Relief valves are set to relieve at the 225 psig (1551 kPa) machine design pressure.
CAUTION CAUTION
!
Water must be within design limits, clean, and treated to ensure proper machine
performance and reduce the potential of tubing damage due to corrosion, scal-
ing, or erosion. Carrier assumes no responsibility for chiller damage resulting
from untreated or improperly treated water.
