REPAIR
Check inlet and outlet connections. This
dryer is designed for air flow in one
direction only. Inlet and outlets are
identified.
Restore a free flow of water. Trap is a
float type. The bowl will normally contain
some water and valves should be free
and clean. Trap should be periodically
checked and cleaned. After initial
installation, the trap should be checked
weekly for dirt, pipe scale, etc. for the 60
days.
Check the valves. Bypass piping should
be installed around the dryer so the dryer
may be isolated for service without
shutting down the air supply. During
dryer operation valves must be set so all
air goes through the dryer.
Blow out the system. Before dryer is first
started all few moisture should be blown
out of the system.
Check actual (scfm) flow through the
dryer. This dryer is designed for a
specified air flow. If air flow into the dryer
exceeds specifications, water removal
capacity may not be sufficient, resulting
in liquid carry-over downstream. Check
the flow of air system.
Check the separator and drip legs ahead
of the dryer. If this dryer is installed at an
individual work station or in one portion
only of the piping system, instead of near
the compressor, there may be an
accumulation of free moisture in the
pipeline ahead of the dryer. If the
moisture is pumped into the dryer
intermittently, water removal capacity
may not be sufficient. A separator or air
line filter with an automatic trap should
be installed ahead of the dryer.
Rated operating temperature is 100°F.
The dryer is designed for inlet air
temperature of 100°F. Temperatures
above 100°F may cause water down
stream and an overloading of the
condensing unit. Increase dryer size or
install an aftercooler.
Clear fins of all obstructions. Clogged
fins in the condenser coil will re4strict air
passage and reduce refrigeration
capacity, causing water down stream.
Fins should be periodically checked and
cleaned. Install ambient air filter.
