Dwyer Mark II Manometers come in a variety of ranges. Make

sure the fluid being used is for the correct manometer.

Mark II #25, 27, MM-80 and M-700 Pa use red gage fluid

(specific gravity 0.826).

Mark II #26, 28 and MM180 use blue gage fluid (specific gravity

1.9).

If additional fluid is required, call, fax or email the Dwyer office

listed at bottom of page.

INSTALLATION

Position manometer on a vertical surface. Drill two 1/8˝ or 9/64˝

holes on a vertical line 3-15/16˝ apart. Loosely mount

manometer with self-tapping screws provided. Adjust gage until

level bubble is centered in level vial, then secure the manometer

tightly.

For portable use, order optional A-612 Portable Stand.

FILLING

Turn the zero set knob counterclockwise until it stops, then turn

clockwise 3 full turns. This puts zero in approximately the middle

of the travel adjustment in either direction. Remove the fill plug

and fill with gage fluid until fluid reaches zero on scale. Minor

adjustments can be made to adjust zero by adjusting zero knob.

Replace fill plug. If gage is overfilled, remove excess by inserting

pipe cleaner through the fill port to blot up excess fluid.

MAINTENANCE

Check fluid level regularly and adjust zero with zero adjust knob.

Be sure tubing connections are disconnected and gage is open

to atmosphere before adjusting zero.

Clean with mild soap and water. Avoid any cleaning fluids which

may result in damaging the gage.

ACCESSORIES

Each Mark II manometer includes two tubing connectors for 1/8˝

pipe or sheet metal ducts, two mounting screws, 1 oz. bottle of

indicating fluid, red and green pointer flags, 8´ of double column

tubing and instructions.
