Introduction
Type HF couplings are designed for horizontal operation. Refer
to the Factory for coupling operation other than horizontal or
for limited end float requirements.
Maximize P
erformance and Life
The performance and life of couplings depend largely upon
how you install and maintain them. Before installing couplings,
make certain that foundations of equipment to be connected
meet manufacturers’ requirements. Check for soft foot. The
use of stainless steel shims is recommended. Measuring
misalignment and positioning equipment within alignment
tolerances is simplified with an alignment computer. These
calculations can also be done graphically or mathematically.
It is recommended that final alignment be checked using either
an alignment computer or graphical analysis. Both methods
allow the incorporation of “cold offsets”, which will
compensate for shaft position changes due to thermal growth.
WARNING:
Lockout power source and remove external loads
from the drive before servicing unit or accessories.
WARNING:
When opening the drain plug, filler plug or orifice
seal plug of a warm or hot fluid coupling, place a rag over the
plug and loosen the plug slowly to relieve any internal
pressure.
WARNING:
Consult applicable local and national safety codes
for proper guarding of rotating members. Guard must not
restrict free flow of air, but the portion of the guard in line with
fusible plugs must be solid construction.
CAUTION:
DO NOT PAINT fluid coupling. Painting will
reduce fluid coupling thermal heat dissipation characteristics.
CAUTION:
DO NOT spray water on a hot fluid coupling, as
this may result in crackin gof aluminum components.
