At the end of operation and overnight, the machine should be switched off using the power switch on
the control unit.
12 Shutdown / hibernation
DANGER OF DAMAGE
The turbine must not be allowed to freeze under any circumstances. Please observe the following
instructions:
Two cases are considered during the wintering of the HydroStar turbines.
In the first case, the water is discharged from the pool, the turbine is entirely over water and in the
second case, the water is not drained from the pool and the turbine is completely under water.
Case 1:
• Turn off the control unit
• Attach a sign.
• Drain the water from the pool far enough that the turbine is completely above water.
• Protect the turbine against frost getting in with suitable material.
After the frost period:
• Remove insulating material from the turbine completely.
• Make sure that there is no residual material in the propeller or in the flow straightener.
• Refill the pool completely with water.
• Start again as described in section 8. Start-up.
Case 2:
• Turbine remains installed
• Turbine must be completely under water
• A freezing of the water must be prevented to the turbine (300 mm below water level)
• The turbine can be used during the winter against the freezing of the water
• Turbine runs at low speed over a period of time
• Pool is cleaned after wintering
• Ensure that there are no extreme dirt or foreign parts on the impeller or in the flow straightener
• Start as described in section 8 Commissioning
13 Maintenance and repair
13.1 General
All work on the HydroStar counterflow unit must be carried out by trained personnel. Before working
on the control unit, disconnect it from the mains and secure it against being accidently switched back
on.
13.1.1 Maintenance
• The HydroStar counterflow unit is maintenance-free.
• The underwater motor has no seals that have to be maintained or replaced.
• Make sure that no objects of pieces or clothing are caught on any protective equipment in the
intake area. Remove those items when the turbine is switched off.
• Have a specialist inspect the counter current unit every two years.
• The control unit can be cleaned with a damp cloth. Do not spray!
13.1.2 Repair
• Repairs are only to be performed by suitably trained specialists or in the manufacturer's
factory.
• Only use original BINDER spare parts for repairs.
