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 1/2” 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.

II NH3 Specific Flowmeter Assembly (FM-1500 N)
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.
NOTE: Start with original calibration number and follow
procedure in manual for verifying flowmeter accuracy.
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.
