4.3 Location and Clearance
Install the dryer on a level pad. Ensure the dryer is
level by grouting or shimming as necessary. Holes are
provided in the dryer base members for floor anchors.
Securely anchor the dryer frame to the floor. Allow 24
inches clearance on all sides of the dryer for servicing.
Provide adequate clearance for separator element and
afterfilter element replacement. Provide protection for
the dryer if it is installed where heavy vehicles or similar
portable equipment is likely to cause damage.
4.4 Piping and Connections
All external piping must be supplied by the user unless
otherwise specified. Refer to the General Arrangement
Drawings in the back of the manual for connection sizes.
Inlet and outlet isolation valves and a vent valve are rec-
ommended so the dryer can be isolated and depressur-
ized for servicing. The connections and pipe fittings must
be rated for or exceed the maximum operating pressure
given on the dryer nameplate and must be in accordance
with industry-wide codes. Be sure all piping is supported.
Do not allow the weight of any piping to bear on the dryer
or filters. Piping should be the same size as or larger
than the dryer connection. Piping smaller than the dryer
connections will cause high pressure drop and reduce
drying capacity.
Consult the factory for piping details if required.
Dryer bypass piping may be installed to allow uninter-
rupted airflow during servicing. If the downstream appli-
cation cannot tolerate unprocessed air for short periods,
install a dryer system in the bypass line.
CAUTION — Do not hydrostatically test the piping
with the dryer in the system. The desiccant will be
damaged if saturated with water.

4.5.2 Automatic Condensate Drains
An automatic electric demand drain discharges condensate
removed by the separator. A second, timer drain, is
provided as back-up. Condensate should be piped to an
open, vented floor drain or sump. See Table 2 for expected
water flow from separator drain.
NOTE:
Discharge is at system pressure. Drain line should
be anchored.
