Invert depths
The Balmoral HydroClear is designed to cater for a drain invert depth of 1m but this can be reduced to 750mm or increased using a Balmoral-supplied extension to suit specific site requirements.

Electrical power requirements

Power requirement is single phase 240V, through a 3-core steel wired
armoured (SWA) cable. Refer to the product drawings supplied with
your unit for location of the air blower housing unit and specific power
ratings to size the electrical cable.

 

 

 

 

 

 

Air blower

The air supply is provided by a linear diaphragm type air blower and is used across all HydroClear models. This style of air blower is proven to be very energy efficient, cool running with a low noise output. The air blower is contained in a moulded polyethylene chamber which sits atop the plant. This chamber is integrated into the vessel turret and also forms a low profile pedestrian cover. Easy access is provided to the air blower for maintenance by removing the top chamber cover only. There is no need to open the main plant access lid.

 

Desludging

It is a requirement of the product warranty that desludging is performed at the required intervals. Proof of desludging, in the form of invoices clearly showing the desludging date, may be required. Failure to carry out regular desludging may affect your Balmoral product warranty. Failure to desludge the system at the appropriate time may result in excessive solids build up. This could result in solids washout which can pollute water courses or block soakaway systems. NB: It is important not to desludge the aeration chamber which contains the active bacteria affixed to the media. Once desludging is complete the plant should be refilled immediately with water (waste or clean) to re-balance internal and external pressures on the plant. Desludging intervals HC 6: 12 months HC 12: 9 months HC 20, 30, 40 & 50: 6 months The desludging interval may be extended on sites where lower solid concentrations exist. A sludge gauge is included to measure sludge levels in the tank(s) and to maximise desludging intervals. Contact Balmoral Tanks for further information.

Servicing requirements

A full service on the plant should be performed every 24 months. The service should ensure that all aspects of the system are functioning correctly. Particular areas of detail include: • Checking all chambers for damage • Checking the full air system including the air blower and diffusers • Checking lid seals and air blower chamber • Checking ventilation system • Checking electrical connections at the plant. It is a recommendation that the air blower filter be checked more frequently on sites which are prone to dusty conditions. This can be performed by following the instructions supplied with the air blower. It is a requirement of the product warranty that servicing is performed at the recommended intervals. Proof of servicing, in the form of invoices clearly showing the servicing date, may be required. Failure to carry out regular servicing may affect your Balmoral product warranty. Service call-outs and service kits are available from Balmoral Tanks. Maintenance contracts are also available on request to ensure you meet your full servicing requirements
