Schreiber Chillers 15medWC - Manual (Page 10)

REMOTE CONDENSER PIPING (NOT APPLICALBE FOR WC)
There are two circuits in this chiller; therefore four pipes are required to connect the chiller and
condenser.
Refrigeration Piping Guidelines (Based on 150ft equivalent length)
Hot Gas Line (comp-to-condenser) 1-1/8”
Liquid Line (condenser-to-receiver) 7/8”
These values are based on 150’ of total piping length, plus equivalent length of fittings. Shorter
runs may allow for smaller pipes, but over-sizing the Hot Gas line lowers the gas velocity, which
prevents proper oil movement through the system. This value MUST NOT BE EXCEEDED, for
any length of pipe.
Refer to the interconnecting diagram for more requirements on piping installation.
