WARNING
Theselectionandinstallation
ofcomponentsexternaltothe
unitaretheresponsibilityofthe
installerandmustbecarriedout
inaccordancewithgoodworking
practicesandapplicablestandards
ofthecountryofdestination.
WARNING
Thehydraulicpipingtotheunit
mustbeadequatelysizedforthe
requiredflowrate.Thewaterflow
ratethroughtheheatexchanger
mustalwaysbeconstant.
WARNING
Carefullycleanthesystempriorto
connectiontotheunit.Thisclean-
ingeliminatesweldingslag,dirt,
rustoranyotherimpuritiesfrom
thepiping.Theseimpuritiesmay
otherwisebedepositedwithin
theunitandcauseamalfunction
Theconnectingpipingmustbe
adequatelysupportedsoasnotto
imposeanyweightontotheunit.
