2.2 Water/Glycol Cooled Unit Piping
Therequiredeldinstalleduidcoolerpipesizesmayormaynotbethesameastheconnection
sizesontheuidcooler(referto2.2.2and2.2.3forconnectionsizing).Thiswilldependonthe
length of pipe and the calculated pressure drop of peripheral components.
Water cooled units may also be connected to building water or tower water sources. Pipe size will
dependonlengthofrunandthemaximumwaterowrequired.
Shut-offvalves(eldprovided)shouldbeinstalledwithinafewfeetoftheinletandoutletconnec-
tionsoftheevaporatortoallowtheunittobeisolatedforservice.Drain/llvalvesshouldbelocated
at the lowest point on the connected piping.
Allwater/glycolcooledunitsareshippedwithplate/nheatexchangersasstandardequipment.A
strainerisshippedlooseandistobeeldinstalledinthesupplylinewithshut-offvalves(eldpro-
vided) before and after the strainer. The strainers and water/glycol piping must be cleaned on a
periodic basis. If the unit is shipped with shell and tube condensers strainers are not required not
shipped with the unit.
All water pipes have a cap installed on the end of the pipe for pressure testing the system. These
caps need to be removed before installing the piping to the units. Use a tube cutter for smaller pipes
and a reciprocating saw with a metal cutting blade for larger pipe sizes or if there is a clearance
problem. All connections need to be cleaned before connections are brazed together.
