Supply header gravity drain

The AHU solenoids are actuated to provide back pressure relief and allow the system to drain. In order to drain the system from the high point located at the Adiabatic media spray bar down to the low point of the supply drain, complete the following steps:

1.Close all of the site AHU supply header isolation valves to the HP POD 240e NA.

2.Remove the installed plug from the supply header drain line and attach the water hose from the drain line to a site drain, if possible.

3.Place the ECS system of the HP POD 240e NA in Winterization mode:

a.On the ECS panel in IT section A, select the lock icon and type 'hpinvent'.

b.Press the Enter button.

c.Select the configure button from the Top View or AD detail screens.

d.Select the Winterize button.

e.The media spray solenoid valves of the Adiabatic units open.

4.If the supply system contains a relief or vent valve, open or pin the valve open to maximize drain capabilities.

5.Open the supply header isolation ball valve by rotating the handle 90º counter-clockwise to align the handle parallel to the ball valve.

The Adiabatic supply header is now draining.

6.When water stops flowing from the supply header, close the drain line ball valve by rotating the handle 90º clockwise to align the handle perpendicular to the ball valve.

7.If the time limit on ECS system Winterization mode has not elapsed, manually turn off the Winterization mode to close the media spray solenoid valves:

a.On the ECS panel in IT section A, select the lock icon and type 'hpinvent'.

b.Press the Enter button.

c.Select the configure button from the Top View or AD detail screens.

d.Select the Winterize off button.

e.The media spray solenoid valves of the Adiabatic units close.

8.Close the relief or vent valve that was opened during step 4, if applicable.

IMPORTANT: Both Aisle A and Aisle B of the Adiabatic units must be drained to complete the Winterization process of the HP POD 240e NA.

Continue preparing the Adiabatic units for winter by completing the Adiabatic unit by unit blowdown (on page 77).
