Page 3: Introduction
The contents of this manual are intended to provide information regarding the installation, operation, maintenance and troubleshooting of Hydro Instruments’ VPH-10000-2 vaporizer. It is critically important to read and become familiar with the contents of this entire manual before proceeding to install or operate the unit. -
Page 4: System Size, Capabilities And Specifications
When working with Chlorine • Ensure that approved, self-contained breathing and safety equipment are always available and ready for use and personnel are properly trained for its use. • Safety equipment should be inspected and maintained in accordance with the manufacturer’s instructions. -

⁄ " concrete anchor bolts through the bottom plate. If installing multiple vaporizers, Hydro Instruments recommends leaving at least 2 feet of clearance space between each vaporizer for ease of access. If using automatic water control, a ½" water pipeline should be installed to the water solenoid valve. -
Page 6: Pressure Relief Valve Assembly
3.2 Pressure Relief Valve Assembly The pressure relief valve assembly is a critical component to any chlorine vaporizer system and is required by ASME code for operation. This mechanical safety device limits the pressure of the chlorine pressure chamber to a maximum value. The rupture disc must be properly installed into the rupture disk holder prior to installing the rupture disk assembly onto the pipe. -

These residues can cause accelerated pipe corrosion and result in a leak. NOTe: Before performing this step, be sure to read Hydro Instruments “Nitrogen Purging” document for further information. -
Page 15: Initial Start-Up
2. Initial Start-up Only refer to the start-up procedure outlined in this section if the previous Section III.1 leak test has already been completed and you are now performing the initial start-up, the piping has been changed, the vaporizer has just been cleaned, or in any other situation in which air/moisture has been allowed to enter the system. -

4.1 Short Term Shut Down A short term shut down is defined as any situation where the chemical feed is only temporarily interrupted, and the heater and all control functions will remain on. Hydro Instruments recommends the following procedure: a. If applicable, temporarily stop chemical feed at the vacuum regulator and allow liquid to fill back into the container. -
Page 17: Long Term Shut Down
Wait for 30 minutes to ensure pressure readings hold at 0 psi and then repeat this step as necessary. d. Purge the system with dry air or nitrogen according to the instructions in the Hydro Instruments Nitrogen Purging document. Then operate the ejector again to remove all gas from the system until the pressure gauges read zero. - Page 18 FIgurE 5: Operating/Configuration Screens Figure 5.

Page 19: Explanation Of Main Controller Screens
5.1 Explanation of Main Controller Screens 1. Operation Screen: This screen displays a live reading of the pressure chamber operating conditions. These parameters include: gas temperature, gas pressure and superheat. 2. Water Temperature: This screen displays a live reading of the water tank temperature. This is the temperature reading that is used for PID control of the water temperature and all appropriate water temperature alarms. - Page 20 The new span must then be adjusted on this screen to match the incoming 4-20 mA signal. Consult Hydro Instruments before changing pressure ranges or pressure transmitters. 16. PID Control Setting: This screen displays and allows the user to adjust the PID control settings of the vaporizer.

6. Operating Controls and Components 1. Chlorine Gas Temperature Thermocouple: The chlorine gas outlet temperature is monitored by a K-type thermocouple through the top flange of the chlorine pressure chamber. For added corrosion protection it is installed with a Hastelloy-C thermowell. Its main function is to provide visual indication of the chlorine gas outlet temperature, and together with the chlorine gas pressure transmitter, is used to calculate and then display the superheat value. -

7. Alarms and Features Refer to Table 4 for a description, and action of all alarms incorporated into the vaporizer unit. Note that while some alarms take preventative action themselves, an operator should always monitor an alarm situation and take preventative action if need be or the situation persists. For information on troubleshooting techniques see Section V. -
Page 23: Maintenance
IV. MAInTEnAnCE 1. Yearly Maintenance 1.1 Chlorine Pressure Chamber Cleaning It is important to inspect and clean the chlorine pressure chamber for signs of corrosion, buildup of debris and clogging. It is recommended to be done on a yearly basis. Ignoring this maintenance step can lead to serious malfunctions of the vaporizer. -
Page 24: Alarms And Switches Testing
1.2. Alarms and Switches Testing Alarms and switches should be tested at least once a year. Before proceeding to perform any testing or maintenance ensure that all chlorine has been completely purged from the system and that the chlorine container valves and inlet manifold piping valves are closed. Please refer to Section III.4.2 for long term system shut down before performing any of the below procedures. -
