Commissioning & Operation
•
When charging the vessel with the water for the first time, make sure that all screw connections are
properly tightened, tighten any loose connections with a suitable tool and make sure that all seals are
firmly seated and leak-tight, particularly the flange seal on the tank.
•
We recommend the use of strainers/filters if the cold water from the mains or the re-circulated hot water
from the circulation pipework contains particles that cause corrosion on stainless steel.
•
Do not operate the equipment at pressures or temperatures in excess of those specified on the
nameplate of the vessel marking and drawings.
•
Do not subject the equipment to conditions of vacuum or partial vacuum.
•
Open the mains stop cock and fill the unit with water.
•
Open successive the air vent on top to purge the unit of air.
•
Open the primary heating circuit successive and adjust the primary control valve on the setpoint and heat
the water to its temperature of use.
•
Check all gaskets/sealings at the water connections and the inspection opening for leaks when the vessel
has reached its working temperature and rectify as necessary. Some bolt tightening maybe necessary after
the unit has been first pressurerised.
•
The periodical change of cold and hot temperatures causes a load alteration on all gaskets and sealings
and degrades its elasticity during the period of operation. This can cause leaks after a certain period.
Call the attention of the user/operator regarding this circumstance. Give the necessary instructions for
periodical checks of all water connections and issue instructions how to refit the leak tightness.
3.1 Maintenance
The AquaTank must be inspected by a competent person in time intervals not exceeding 1 year.
Annual maintenance should include cleaning and debris from the base of the vessel to comply with guidelines
on prevention of legionella bacteria proliferation.
The leak-tightness of all screw and flange connection seals must be checked at regular intervals. Because of
constantly fluctuating temperature loads, i.e. topping up with cold water when water is extracted and re-
charging to tank temperature, the elasticity of the seal materials used suffers during the life of the system. The
tension of the screw connections can decline at the same time, resulting in leaks.
Open the air vent and pipe the drain to a drain point and open the drain valve.
The cylinders internal condition can be inspected by removing the inspection cover to allow visual examination.
Re-fit the gaskets/sealings and re-fill the vessel according to the commisioning instructions above.
