SECTION 7 – BLADDER TANK FIRST FILLING
The bladder tank foam lling is a simple operation to perform if the instructions contained in this manual are carefully followed. The
lling process is a fundamental task determining the proper bladder tank performance when required to operate. Incorrect lling
may compromise the bladder’s lifetime or cause an immediate rupture. It is highly recommended that the installer/user contacts
Viking in case of doubts on the instructions shown in this manual. Viking is not responsible for any damage to the bladder if the
lling operation is not made by Viking.
7.1 Separation bladder
• Viking certies and guarantees, with release of a test certicate, that all the separation bladders have been subjected to a
pneumatic pressure test for integrity assessment.
• Viking guarantees the bladder integrity for one year starting from the delivery date;
• Viking guarantees the bladder against tearing or bursting only and exclusively if the lling operation is performed by Viking’s
employees or by Viking authorized personnel. The operator performing the lling will validate this activity and activate the
warranty covering the bladder by sending back to Viking the certicate of warranty duly undersigned.
• To avoid bladder damages the installation of a strainer upstream of the tank is recommended;
• To avoid damaging the bladder, DO NOT perform welding on the tank body.
