Visually inspect a fluid cooling tower and its components for issues that need to be addressed for the upcoming seasonal maintenance. First, you'll learn how a fluid cooler normally operates and what to look for during a preventive maintenance check. Then you'll inspect the water basin and its components, the spray pump system, coil, and the fans.

Learn how to perform a seasonal maintenance procedure on a de-energized fluid cooler. In Fluid Cooler Preventive Maintenance Checks you noted items that needed to either be cleaned or fixed. In this simulation you'll get to actually clean and fix those items.

The Foundations of PV course is for those just starting out in the industry, who wish to gain a deeper and broader foundational knowledge about all aspects of modern solar photovoltaics. We explore the early and recent history of the field, and explain in detail the wide range of applications of solar technology, both off the grid and connected to utility power, including a clear explanation of where and how the current explosive growth in grid-connected systems started. You will also become familiar with all the key electrical components of various PV solutions, and how they work together to give power day and night, including the emerging trend for battery storage.

In this course you'll learn how to build the exterior wall of a house using the platform framing construction method. First, you'll learn how framing a wall fits into the overall construction process, the construction methods used for building them, and how to stay safe when framing walls. Then in the simulation you'll get to build and install the framing for the front wall of a house in three sections: a wall section, a door section, and a window section.

In this course you'll learn how to construct a wooden floor frame from sill plate to sheathing. First, you'll learn about different types of floor frames, the tools and materials needed, and how to stay safe while building a floor frame. Then in the simulation you'll get to build the sill plate, rim joist, beam, install floor joists and hangers, build a knockout for the stairs, and install sheathing on top of a basement foundation.

This Fundamental Electrical Concepts course lays the foundation for all other electrical courses by explaining the origins of the major fundamental electrical concepts in simple terms and how they relate to one another.

Solve for over 20 common service faults associated with a typical residential gas boiler including circulator, burner and electrical problems.

This is an assessment simulation, where you'll use the steps and skills you've learned and practiced on the Interplay platform to determine the fault and fix each scenario. Use the bottom tool bar to navigate around the environment, inspect components, access tools, and view diagrams. This is designed to mimic a real-world scenario, so there's no step by step guide giving you instructions for how to troubleshoot the scenario.

A brief overview of residential gas furnace commissioning and operational checks. This course will provide an overview of the procedures used to evaluate the overall quality of a newly-installed gas furnace, with emphasis on gas supply, proper venting and condensate removal, electrical wiring and connections, and the start up procedures.

Learn to troubleshoot a typical residential gas furnace (80% mid efficiency) surrounding over 20 life like service calls surrounding burners, safety switches and motor operations.
