4.3 Initial Startup Procedure
Before starting the Hot-Pak, all equipment should be inspected for proper installation.
Any equipment that appears to be damaged or any installation errors should be
corrected before any water, steam or electricity is supplied.
When starting up, always introduce the cold fluid first. Introduce the hot side fluid
slowly. Bring the unit from ambient temperature up to operating temperature
gradually. Do not introduce hot or cold fluids suddenly, which could damage the
unit and void the warranty. A qualified electrician should make all electrical
connections.
Initial startup procedures are as follows:
1. Assure that all manual shutoff valves on the water and heat sources are closed.
Verify that electricity is off as well.
2. Slowly open the manual shutoff valve or valves on the cold water side of the Hot-
Pak and check for any leaks. Repair any leaks before proceeding. Allow the tank
to fill completely with water. Opening the safety relief valve to vent the air out of
the shell will speed up this process.
3. Open the circulator pump isolation valves. (Figure 4-5)
