IMPORTANT:
Opening the flowmeter will void the Flow
Calibration value assigned to your unit. However, you may
need to take the flowmeter apart for periodic cleaning or to
remove an obstruction.
See Illustration below for flowmeter
reassembly instructions.
TO REMOVE THE FLOWMETER:
Loosen two ½” bolts securing unit (shutoff valve end) to
tool bar. Loosen union between flowmeter and shutoff
valve. Slide shutoff valve away from flowmeter and unscrew
flowmeter from heat exchanger.
To disassemble the flowmeter:
Remove retainer clip from one end and slide out internals.
See Illustration below. Be careful not to bend turbine shaft.
Clean and inspect parts.
Assemble in reverse order.

WARNING
TO PREVENT SERIOUS INJURY, DO THE FOLLOWING:
1.
ALWAYS
WEAR
gloves, goggles, and other
necessary equipment when handling NH3
apparatus.
2.
DO NOT cross thread. Use anti-seize lead base
thread compound.
3.
THOROUGHLY
BLEED
hoses before disconnecting
NH3 apparatus.
4.
COMPLETELY
EVACUATE
NH3 apparatus before
servicing.
After assembly, shaking flowmeter end-to-end should
produce a “rattling” sound (shaft end play). Blowing into
the meter from either end should cause the turbine to spin
freely. If the turbine only spins from one direction, install the
flowmeter so that liquid flows that direction.
If turbine does not spin freely, flowmeter may require repair.
Turbines and bearing replacement kits are available.
Before reconnecting the union, loosen all six 3/8” carriage
bolts at bottom of mounting bracket uprights. Tighten union
then re-tighten 3/8” carriage bolts. This ensures that unit sits
flat on tool bar and does not “teeter” on center bracket.
Start with original calibration number and follow procedure
in manual for verifying flowmeter accuracy.
