Country Inn & Suites by Radisson of Lansing Low GWP Refrigerant Safety Training for Air Conditioning

This course will cover Low GWP Refrigerants and their safe applications for air conditioning systems.

As the HVACR industry continues to move forward and innovate, refrigerants that were once commonplace to air conditioning systems are now being phased out. Replacing them are more energy efficient, environmentally friendlier refrigerants, known as Low Global Warming Potential (GWP) refrigerants. Many of these new refrigerants are classified by ASHRAE as A2L, or slightly flammable.  As a result of these changes, air conditioning installers and service technicians will require additional training for the safe handling and transportation of these refrigerants.  Equipment manufacturers are now using Low GWP / A2L refrigerants in their product lines.

Topics Include:
• Refrigerant safety
• Introduction to Low GWP refrigerants
• Refrigerant properties and characteristics
• The refrigeration cycle
• Working with refrigerant blends
• Proper installation and service guidelines
• Flammable refrigerant considerations
• Explanation of the associated codes and standards for A2L refrigerant

Certification:
As part of this course, a training manual will be provided in advance that covers the class objectives. At the end of the course, an open-book 50 question assessment will be provided that verifies the comprehension of the course material.

Includes:  study manual, class instruction, test and breakfast. 7:30 am registration & breakfast.  $150pp

Johnstone Muskegon Bosch IDS Heat Pump Training

Bosch Inverter Duct Split (IDS) heat pump systems provide the ultimate in quiet and efficient home heating and cooling. During colder months, these air-to-air heat pumps extract heat from the outdoor air during colder months for heating, and extract heat from the air inside the home to expel it outside during warmer months for cooling.

This day-long training course will cover both the installation and diagnostic service of Bosch IDS Heat Pumps and is divided into the following sections:

Bosch IDS Light & Premium Intro & install (2hrs): The Bosch IDS Light 15 SEER System is the first inverter condenser to combine premium inverter technology with standard efficiency. It is available in 24k, 36k and 60k BTU capacities. The IDS Premium 20 SEER System combines the top tier BOVA20 and BOVC20 outdoor units with the exceptional BVA20 two stage constant torque ECM style air handler.

Bosch IDS Ultra (Cold Climate Heat Pump) Intro & Install (2hrs): The Bosch IDS Ultra Heat Pump can provide reliable, energy efficient heating even in sub-zero temperatures. This cold climate heat pump can provide 100% heating down to an outdoor temperature of 5° F and will continue to initiate heating even down to -13° F.

Bosch IDS Diagnostics training (4hrs):  This segment will cover troubleshooting and diagnostics of the various heat pump models.
