Fluid is dripping from the system? If possible, collect the fluid in a bucket and contact an engineer qualified to
work on unvented systems.
The controller issues a message telling me the sensor is faulty or
there is a cable break?
Contact an engineer qualified to work on unvented systems.
The cylinder is not providing sufficient hot water? Check that the hot water temperature is set correctly on the controller
(recommended value of approx. 45 °C, however, set periodically to 60 °C to
provide protection against the proliferation of harmful bacteria) and
that the gas-fired boiler is working. If the settings are
correct, the cylinder may be calcified. Then: contact an engineer qualified to
work on unvented systems.
A safety thermostat trips? Contact an engineer qualified to work on unvented systems.
Water escapes from the expansion relief valve? Contact an engineer qualified to work on unvented systems.
5 Inspection and maintenance
An annual inspection/maintenance run by an engineer qualified
to work on unvented systems is a prerequisite for ensuring that
the cylinder is permanently ready for operation, reliable, and has
a long service life.
It is important that your hot water cylinder is serviced annually.
We recommend entering into a maintenance agreement.
After servicing, the servicing engineer must complete the relevant
Service Interval Record section of the Benchmark Checklist
located on the inside back pages of this document.
e Risk of death from electric shock.
Improperly executed work on the cylinder can result in
a risk to life and limb.
- Never try to rectify cylinder malfunctions yourself.
- Contact an engineer qualified to work on unvented
systems to rectify all malfunctions.
a Risk of injury resulting from improper maintenance or
repair.
Failure to arrange for the system to be maintained
and repaired and improper maintenance and repair
can impair the operational safety of the unit, leading
to injuries and damage to property
- Never attempt to perform maintenance work or
repairs on the cylinder yourself.
- Always employ an engineer qualified to work on
