SECTION 3 - INSTALLATION
Evaporator And Condenser Water Piping
The evaporator and condenser liquid heads of chiller
have nozzles which are grooved, but also suitable for
welding 150 psig DWP flanges or the use of flexible
couplings. Factory mounted flanges are optional. If
welding is done on the nozzles, flow switches, con-
denser level sensor, and water temperature thermistors
should be disconnected and the welding ground MUST
be good contact located at the head to prevent current
damage to the devices.
The nozzles and water pass arrangements are furnished
in accordance with the job requirements (see Product
Drawings furnished with the job.) Standard units are
designed for 150 psig DWP on the water side. If job
requirements are for greater than 150 psig DWP, check
the unit data plate before applying pressure to evapora-
tor or condenser to determine if the chiller has provi-
sions for the required DWP.
Inlet and outlet connections are identified by labels
placed adjacent to each nozzle.
