In some instances local codes may dictate the use of a rupture disk to prevent damage to the chiller in the event of overpressurization of the high and low temperature generators. SANYO units are provided with a flange for mounting a rupture disk.

At this flange connection, a rupture disk may be installed and connected to a field-provided overflow tank per Figure 66.

It is the responsibility of the installing contractor to install the rupture disk on the units and overflow tank (if required) prior to initial chiller startup.

Discharge piping

Rupture disk mounting instructions are as follows:

1.Prior to installing or replacing the rupture disk, insure that a slight positive pressure is maintained in the chiller with nitrogen gas.

2.Apply Teflon paste to both sides of gasket.

3.Align gasket as shown in Figure 68.

4.Assemble flanges and torque per specifications shown in the manual of rupture disk.

5.Conduct leak test using nitrogen gas at 49 kPa (0.5 kg/cm2G) after installation of rupture disk.

6.Periodic maintenance should include tightening the rupture disk with a torque wrench.
