Users Manual

General

The cross-section drawings of the Gauge found in Figures 5-1, 5-8 and 5-12 will aid in identifying and assembling the appropriate parts, and in determining the order of installation.

If the High Range Piston Assembly is to be used, the 2470 Column adapter is required.

1.If not in place, remove the 2465/2468 P/C from the column, store safely in its P/C container per instructions below.

2.Install the 2470 style column top (P/N 2470-1-143). Tighten the column top firmly by hand while holding the bottom section of the column with the opposite hand. The column adapter should make a pressure tight seal against the Column O-ring

(P/N 54-703-109).

3.The O-Ring should be lightly lubricated with Dupont Krytox Grease (45-351) before installation. All excess lubricant should be wiped off, leaving only a slight film

Conversely the Low or the Mid-range P/C is to be used:

1.Remove the 2470 P/C from the column and store it in the P/C shipping container.

2.Unscrew the 2470 style column top and install the 2465 style Pressure housing adapter (P/N 2465-4-1).

3.Tighten the column top firmly by hand while holding the bottom section of the column with the opposite hand. The column adapter should make a pressure tight seal against the Column O-ring (P/N 54-703-109).

4.The O-Ring should be lightly lubricated with Dupont Krytox Grease (45-351) before installation. All excess lubricant should be wiped off, leaving only a slight film.

Low Range Piston Assembly

Refer to Figures 5-1, and 5-2. If the Low Range Piston Assembly is to be used:

1.Drop the filter (24-580) and filter retainer (2460-4-27) into the base.

2.Drop the lower thrust bearing (2460-4-25) into the recess at the top of the filter retainer. (See Figure 5-2.) The O-ring (54-703-119) rests on top of the filter retainer and seals against the bottom of the cylinder.

3.The O-Ring should be lightly lubricated with Dupont Krytox Grease (45-351) before installation. All excess lubricant should be wiped off, leaving only a slight film

The lower thrust bearing must be in the gauge when the Low Range Piston is being used.
