When hnging the defult pre pressure of the expnsion vessel (1 r) is required, tke following guidelines into ount: Only use dry nitrogen to set the expnsion vessel pre pressure. Inpproprite setting of the expnsion vessel pre pressure will led to mlfuntion of the system. Chnging the pre pressure of the expnsion vessel should e done y relesing or inresing nitrogen pressure through the shräder vlve of the expnsion vessel. Shräder vlve 6.3.5 To hek the wter volume: Exmples Exmple 1 The indoor unit is instlled 5 m elow the highest point in the wter iruit. The totl wter volume in the wter iruit is 100 l. No tions or djustments re required for either underfloor heting loops or rditors. Exmple 2 The indoor unit is instlled t the highest point in the wter iruit. The totl wter volume in the wter iruit is 350 l. Rditors re instlled, so use the grph of 80 C. Ations: Beuse the totl wter volume (350 l) is more thn the defult wter volume (140 l), the pre pressure must e deresed. The required pre pressure is: Pg = (0.3+(H/10)) r = (0.3+(0/10)) r=0.3 r. The orresponding mximum wter volume t 0.3 r is 205 l. (See the grph in the hpter ove). Beuse 350 l is more thn 205 l, the expnsion vessel is too smll for the instlltion.
