SECTION 3 – HANDLING, STORAGE, INSTALLATION AND REASSEMBLY
HOT INSULATION AND COLD INSULATION
PROCEDURE
The installation of insulation is out of
scope. The customer is responsible for
performing the work.
1. The recommended materials and their thickness
for hot insulation and cold insulation are shown in
Table 1 on page 30 .
2. Use a bonding agent, iron wire, iron band, and so
on to fix the hot insulation and cold insulation ma -
terials. Never rivet them. Johnson Controls does
not recommend the use of welding pins.

POINT THAT MUST NOT BE
HEAT-INSULATED
Exhaust gas flue duct Evaporator shell Sight glass
Heat exchanger Evaporation water changer casing Valve manipulator
High temperature generator Refrigerant spray piping Pressure gauge
Waste hot water heat exchanger Refrigerant blow piping Thermometer insertion hole
• Low temperature generator
• Waste hot water-driven generator Point carrying Cold Insulation label Relay insertion hole
Point carrying Hot Insulation label • Exhaust gas inlet temperature sensor

3. Make sure that the outer covering, flanged parts,
and evaporator water chamber casing can be eas-
ily removed to facilitate servicing.
4. The points that require hot insulation or cold insu-
lation are shown in Figure 7 on page 31 .
5. The casing of the absorber and condenser water
chamber does not require insulation. If you use
insulation, make sure it can be easily removed.
6. For the high temperature generator, install the in-
sulation so that the front, sides, and rear insulation
can be removed separately. In addition, make sure
that the insulation around the exhaust gas inlet
and the outlet inspection windows can be easily
removed.
