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.
5. Make sure that the outer covering, flanged parts,
and evaporator water chamber casing can be eas-
ily removed to facilitate servicing.
6. The points that require hot insulation or cold insu-
7. The casing of the absorber and condenser water
chamber does not require insulation. If you use
insulation, make sure it can be easily removed.
8. For the high temperature generator, install the in-
sulation so that the front, sides, and rear insula-
tion can be removed separately. In addition, make
sure that the insulation around the exhaust gas in-
let and the outlet inspection windows can be eas-
ily removed.
