 UNIT STARTUP PROCEDURE INSTRUCTIONS
1) Assure that all manual shutoff valves on boiler water/high temperature hot water and
domestic water lines are closed.
2) Slowly open the manual shutoff valve on the cold water inlet line, checking to ensure that
there are no leaks at the valve or any joints.
3) Adjust the operating temperature control to the desired temperature. Refer to Section 3.10
and Section 3.11 for the exact location of controls and detailed adjusting procedure.
4) Adjust the high temperature limit per actual operating conditions. It is normally factory set
at 20°F above the setpoint, which is default 140°F operating supply water temperature.
5) Open the boiler water/ HTHW return valve.
6) Slowly open the manual shutoff valves on the power source inlet.
NOTE:
This procedure is similar for both boiler water and high temperature water energy sources.
CAUTION!
Boiler water and high temperature water present situations that can be very dangerous
because of the high temperatures and pressures. Use common sense, and follow all accepted
and recommended procedures when performing installation, operation, and maintenance
procedures, to avoid possible injury or death.
7) If no leaks are found, slowly continue to open the manual shutoff valves on the power
source inlet.
8) As the unit is initially heating the water, carefully re-inspect the water inlet, the water
outlet, power source inlet (boiler water or high temperature water), and boiler water
return lines and joints for signs of leakage.
9) As unit approaches the desired operating temperature, check that the temperature on the
unit is within the desired range. If necessary, readjust the temperature control valve.
See the Submittal documents and the temperature control valve component manual,
included with the unit, for the exact location of the valve and detailed adjusting
procedures.
10) After the unit has reached operating temperature, re-inspect all joints for signs of
leakage. In addition, check all gauges and controls to verify that the energy source
pressures are within design specification.
11) The unit is now ready for normal operation. Proceed to Section 3.7 for setting the
temperature and other initial startup parameters using the controller.
