HOT INSULATION AND COLD INSULATION
PROCEDURE
The installation of insulation is out of
scope. The customer is responsible for
performing the work.
The recommended materials and their thickness for hot
insulation and cold insulation are shown in the table
below.
4. Use a bonding agent, iron wire, iron band, or other
appropriate materials to adhere the hot insulation
and cold insulation materials. Never rivet them.
Johnson Controls does not recommend the use of
welding pins.
