INSULATION METHODS TO AVOID:
1. Do not insulate moving parts, such as valve handles.
2. Do not insulate thermowells.
3. Do not cover sight glasses with insulation.
4. Do not cover pipe connections, since they must be accessible
for pressure and vacuum tests.
5. Do not cover pump motors with insulation.
6. Do not use weld pins to attach insulation.

PROPER INSULATION PRACTICES:
1. Insulation on pumps, valves, sight glasses equipment and
ange sections should be mounted so that it can be removed
easily.
2. Water boxes or cover plates must be removed/opened from
time to time for tube cleaning. Valves, pumps and nozzles
must be accessible for servicing and operation.
3. Insulate auxiliary and instrument piping by wrapping glass
wool around it.
To mount insulation materials, use
bonding agents, wires or bands. These
methods do not penetrate the chiller
system and jeopardize the integrity of
the vacuum pressure in the chiller.
WELD PINS ARE NOT ACCEPTABLE.
