This unit of competency defines the skills and knowledge required to perform maintenance procedures and/or repairs on cooling towers or evaporative condensers, associated equipment and controls to ensure performance to relevant Australian Standards, regulations and codes.

Cooling towers and evaporative condensers form an integral part of the refrigeration system in commercial, industrial and air conditioning fields. The towers, condensers, centrifugal water pumps, fans, valves and controls comprise the maintenance/repair work skills relevant to this field and must be assessed in this context.

Where the refitting or repair/replacement of components involves the fabrication and installation of pipework and assemblies then unit MEM10010 Install pipework and pipework assemblies should also be selected.

Where water treatment only is required then unit MEM13007 Maintain water treatment systems for cooling towers should be selected.

Where rectification, modification involving electrical disconnection and reconnection is required unit MEM18049 Disconnect/reconnect fixed wired equipment up to 1000 volts a.c./1500 volts d.c. should also be selected.

There is legislation, regulation and codes of practice for cooling towers in each jurisdiction. Relevant material should be referenced.

You may want to include more information here about the target group and the purpose of the assessments (eg formative, summative, recognition)

List each assessment task's title, type (eg project, observation/demonstration, essay, assingnment, checklist) and due date here

Assessment task 1: [title]      Due date:

(add new lines for each of the assessment tasks)

Copy and paste from the following data to produce each assessment task. Write these in plain English and spell out how, when and where the task is to be carried out, under what conditions, and what resources are needed. Include guidelines about how well the candidate has to perform a task for it to be judged satisfactory.

This field allows for different work environments and conditions that may affect performance. Essential operating conditions that may be present (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) are included.
Components include one (1) or more of the following:	fan motor fan blade pump pump motor sprays condenser valves (bypass, shut-off and temperature control valves) thermostat drift eliminators V belt water strainer
Test equipment includes one (1) or more of the following:	sling psychrometer thermometer refrigeration gauges vacuum pump leak detector multimeter insulation resistance tester

Copy and paste from the following performance criteria to create an observation checklist for each task. When you have finished writing your assessment tool every one of these must have been addressed, preferably several times in a variety of contexts. To ensure this occurs download the assessment matrix for the unit; enter each assessment task as a column header and place check marks against each performance criteria that task addresses.
