20 YORK INTERNA TIONAL FORM 160.81-EG1 Application Data (continued) evaporator and condenser when the pumps are shut off. Piping should be adequately supported and braced inde- pendently of the chiller to avoid the imposition of strain on chiller components.
21 YORK INTERNA TIONAL FORM 160.81-EG1 nected in series and condenser water circuits connected in parallel. All of the chilled water flows through both cool- ers with each unit handling approximately one-half of the total load. When the load decreases to a customer se- lected load value, one of the units will be shut down by a sequence control.
22 YORK INTERNA TIONAL FORM 160.81-EG1 Application Data (continued) In addition, the ASHRAE Standard 15 requires a refriger- ant vapor detector to be employed for all refrigerants. It is to be located in area where refrigerant from a leak would be likely to concentrate.
