3. Installation
The following section discusses installation considerations in more detail.
3.1 Preliminary checks
Carefully unpack the MSL600 control unit, transducer, and mounting bracket arrangement from their packaging.
Check that there is no visible damage to any of the packed parts, paying particular attention to the transducer and transducer cables, and the membrane keypad and display area on the MSL600.
Contained in the packaging should be the following:
Pack one
•1 x MSL600 bridge mounted unit, with compressor housing containing the air compressor for
•1 x MSL600 manual.
Pack two
•1 x transducer assembly, and bridge mounting kit (including tool kit).
(Optional – MSL603 transducer only with 10 metres of cable and air hose)
3.2Location
Determine the optimum location for installation of the MSL600 following the hints and tips given in section 2, Application planning.
3.3 Mounting bracket attachment
The mounting bracket is specifically designed for mounting on the centre rail of the safety railing on the bridge of any settling tank, see Figure (5). The rail can be any diameter up to 52mm (2 inches).
The bracket is also clamped to the bridge kicking board or similar supporting frame.
Adjustments can be made for different bridge heights, and the bracket can be angled to miss obstructions.
An extension arm can be added to the main support tube to extend the adjustment of the bracket further, if required. Most adjustments are made by hexagon key and spanner, included in the supplied bridge mounting kit.
The transducer arm hangs vertically from a pivot and can be swung out of the water for cleaning and inspection.
WARNING!
The transducer is a sensitive instrument and care must be taken to prevent unnecessary impact or strain on it during installation.
3.3.1Bridge preparation
The bracket should be prepared and initial adjustments made off the bridge. If any obstructions are present in the installation area, the unit should be set up accordingly. This will greatly simplify any adjustments required during mounting of the unit on the bridge. The cable and hose from the transducer should be handled with care to prevent any sharp bending, especially in the area where they exit the transducer arm.
Check there is sufficient room between the top rail, centre rail, and any other structure for the control box to be fitted. The space required is 430mm (17 inches) high and 360mm (14 inches) wide [see Figure (5)].
Measure the distance from the water surface to the centre rail of the safety railing (dimension A). Measure the distance from the centre rail to the kicking board (dimension B) or similar structure.
