INSTALLATION INSTRUCTIONS

1. Before installation, check whether the connections used match the maximum pressure
of the filter.
2. Shut off air pressure from air system. Install the filter vertically with the bowl down
in the air line. Ensure that the filter is installed with inlet/outlet air flow in the proper
direction of arrow on the unit. The filter should be installed upstream of regulator(s),
lubricator(s), and cycling valve(s) in the air line, and should be as close as possible to
the device being serviced when used as a main line filter and/or as a final filter.
3. Connect pipes to the inlet and outlet ports using pipe thread sealant tape on male
threads only. When screwing pipes together, prevent ingress of shavings and sealant
to the interior of the unit. Contaminations in the unit may cause it to fail.
4. Make sure that all connections to the filter are tight and secure.
5. Push bowl, or bowl with guard, into the filter body and turn fully clockwise before
pressurizing.
6. The filter must be installed in such a way that no mechanical force or tension occurs.
OPERATING INSTRUCTIONS (See Figure 2)
1. Let the filter run with air supply on. Ensure that the pressure to the air inlet of the filter
from air line does not exceed the maximum pressure specified in the instructions.
2. The filter is equipped with a manual drain. Turn manual drain valve to drain
accumulated liquids inside the bowl. Take care to drain the liquids from the bowl
whenever necessary and always keep the liquids below the baffle.
3. The filter element should be replaced when the pressure drop across the element
exceeds 15 psi. When an excessive pressure drop across a saturated but
uncontaminated element occurs, it may indicate that the tool being operated exceeds
the maximum flow rate (CFM) of the filter (See Specifications). Refer to the
maximum flow rate of your filter and make sure that the required CFM of the tool is
within the maximum flow rate of your filter for best tool operation.

MAINTENANCE
Maintenance Steps
1 disassembly (See figure 2)
• Filter can be disassembled without removal from air line.
• Shut OFF inlet pressure. Reduce pressure in inlet and outlet lines to zero.
• Remove bowl. Push into body and turn counterclockwise.
• Disassemble in general accordance with the parts illustrated in Figure 2. Do not
remove the drain unless replacement is necessary. Remove and replace only if
drain malfunctions or is being replaced with optional automatic drain (4ZK14A).
2 cleaning(See figure 2)
• Clean polycarbonate bowl with warm water only. Clean other parts with warm
water and soap.
• Rinse and dry parts. Blow out internal passages in body with clean, dry
compressed air. Blow air through filter element from inside to outside to remove
surface contaminants.
• Inspect parts. Replace those found to be damaged. Replace plastic bowl with a
metal bowl if plastic bowl shows signs of cracking or cloudiness.
3 assembly (See figure 2)
• Lubricate o-rings, the portion of the manual drain body that contacts the bowl,
and the hole in the manual drain body that accommodates the stem of drain
valve with o-ring grease.
• Assemble filter as shown on Figure 2.
• Torque items listed in Torque Table.
• Push bowl, or bowl with guard, into body and turn fully clockwise.
