H-3630A
Water Retention Apparatus

Introduction
This apparatus consists of eight main components:
1. A perforated brass dish
2. A brass funnel
3. A glass stopcock
4. A glass flask
5. A vacuum dial gauge
6. A vacuum regulator
7. An aspirator pump
8. A wood stand
9. Filter paper, medium speed
Note: The use of Mercury fluid is no longer necessary with this instrument,
since the dial gauge and regulator replace the manometer and relief column
of the previous models.
Specifications
Dial Gauge
Accuracy: +/-1.5% of Span, mid half
Range: 0 -70 mm Hg Vac
Case Size: 2.5"
Vacuum Safety: 120% of Span
Vacuum Regulator
Range: Regulates 0 to 20" Hg
Flow Condition: up to 70 Liters per minute
Wetted Metal Parts: Copper Alloy; Brass
The H-3630A meets specifications for the following tests:
ASTM C91, ASTM C207, ASTM C110, ASTM E149
To verify operation a known testing cement, e.g., Portland S with silica sand
should be used to compare the unit to established readings.
Unpacking
Your unit was thoroughly inspected before it was shipped and should be ready to
operate as soon as you have completed the set-up procedure. Notify Humboldt Mfg.
Co. or your local agent and file a claim with any carriers involved if you find any damage
to the apparatus.
Setup
Place the stand on a stable surface in close proximity to the vacuum source which can
be the water connected aspirator pump or a mechanical vacuum pump. Attach a
vacuum hose (user supplied) between the pump and the water retention apparatus
regulator the hose should be capable of withstanding the full vacuum to be applied
by the pump.
Orient the gauge and regulator to your preferred viewing angle by loosening the
rubber-lined, tube clamp located between the gauge and regulator. Rotate the
flow line(s), to accommodate, then retighten.

Adjustment Procedure:
IMPORTANT: Turn the vacuum regulator adjustment knob clockwise until it is fully
closed, then apply sufficient vacuum from your source pump to conduct a test. The
regulator can withstand full vacuum, but the output must always be below the dial
gage safe limit of 85mm Hg max, To adjust the vacuum to 51mm close the glass
stopcock above the flask and back out the regulator adjustment knob by turning it
counterclockwise and observing the dial gage. When you have reached the 51 mm
band on the gage proceed to use the gasket seal, perforated dish and the correct
wetted filter paper, and then open the stopcock valve applying vacuum to the funnel.
Check for leaks by observing gasket and tubing seals and using a leak testing fluid if
necessary. An adjustment in the regulator setting may done at this time to achieve
the 51mm level under full flow conditions.
Maintenance
Sealing connections and surfaces should not allow foreign material to enter the gage,
regulator or pump. Pipe joint compound is recommended in place of Teflon tape.
To facilitate easy re-assembly apply a light film of fluid compound to joints and fittings.
