e.
Connect ¼” air line from top row “T” fittings to dryers located directly below
f.
Connect ¼” air line to
90˚fittings located on bottom row of dryers
7.
CAUTION: Slowly pressurize system
8.
Check air line fittings for leaks and repair as necessary
9.
Observe dryer operation for proper function as described above in “Pneumatically Controlled”
Pneumatically Controlled (PC) 40 thru 200 CFM SFD Dryer Systems
Pneumatic Control (PC) manages regeneration
cycles by metering a measured air flow through
pneumatic manifold at approximately 60 second
intervals– no electrical requirements. Example: 120
cfm – 1 cartridge regenerates every 60 seconds as
three cartridges continue to receive wet air.
During operation, a light flow of air from ONE
exhaust port (muffler) is normal as this represents
regeneration cycle of desiccant. The air flow will
switch from one exhaust port (muffler) to the next
one approximately 60 seconds in conjunction with pneumatic manifold cycles.
Dryer cycles produce a momentary burst of air from one SFD exhaust port (muffler). This is normal and
will occur each time SFD cycles.
Mounting
1.
Determine proper location for SFD as described in “General Mounting Instructions” pg. 7
2.
Install wall strut with small slots next to wall and on top.
3.
Mount SFD base assemblies as follows:
a.
40 CFM (2 cartridges) units direct to wall or at point of use
b.
80 cfm (primary and auxiliary unit – 4 cartridges
c.
120 cfm 2 auxiliary units (4 cartridges)
d.
200 cfm 3 auxiliary units (6 cartridges)
4.
Assemble inlet and outlet manifolds to base assemblies making sure to apply an anti-seize
(included with dryer) to threads of each retainer bolt.
REMINDER:
Inlet and outlet ports may be installed on right or left side of dryer to accommodate
hose routing
5.
Connect high-pressure air lines (190 psi/13.1 bar max) to inlet and outlet ports of manifolds
REMINDER
: Use appropriate thread sealant on air line fittings to prevent leaks
6.
80 CFM:
a.
Install black ¼” air line to connect front right side port of SFD primary unit to right front port
of SFD auxiliary unit
b.
Install black ¼” air line from left side of primary unit to left side of auxiliary unit
7.
120 /200 CFM units:
a.
Connect one ¼” air line from primary unit with a 90° fitting located on a dryer’s die cast
aluminum manifold to pilot port of PC control
b.
Install ¼” air lines one to each remaining connectors located at back of PC
