q Set the range set valve to the Lo Q RPT:

r Remove the reservoir lid (shown removed in

Figure 2):

This kit is a tool to completely fill the E-DWT-H
internal test volume with liquid test fluid, and
minimize residual air in the system.

Assembly

The fill kit is shipped partially assembled. To
complete assembly, connect as shown in Figure 1
by sliding the 3/8" tubing onto the reservoir ports
and 1/4" tubing and secure with the hose clips
included in the kit. The clips can be initially closed
by hand, then tightened using pliers. The tubing
will slide onto the barbed connection tightly
without a hose clip.

Procedure

n Plug the E-DWT-H test ports: Use the provided

DH500 plugs to plug both of the DH500 female
test ports on top of and on the rear of E-DWT-H.

s Thread the brass standoff into the port at the

bottom of the reservoir.

t Open the slide valve by sliding the shuttle up:

Valve operation is UP-OPEN and DOWN-CLOSED
when the kit is in the orientation shown in
Figure 1.

Squeeze the hand pump until vacuum is near

25 inHg. Read the vacuum on the gauge
attached to the hand pump.

Close the slide valve by sliding the shuttle

down.

Fill the reservoir cup halfway with the liquid test

media. Refer to E-DWT-H User’s Manual for
supported test fluids.

Remove the brass standoff from the reservoir

port. Liquid will be drawn into the evacuated
system.
