8.1 APPLICATION AND CHECK ANALYSIS
To achieve the best dryer performance, you should care-
fully check that the design and installation requirements
outlined below are satisfi ed.
Operating pressure of ZEKS Eclipse dryers can range
from 75 -150 PSIG. Air available for your usage will vary
with operating pressure. The maximum allowable working
pressure of the standard Eclipse ZPA Heatless Dryer is
150 PSIG. Consult your ZEKS representative for units re-
quiring a higher operating pressure.
The dryer must never be installed where air and/or ambi-
ent temperature exceeds 120°F or drops below 50°F. Lo-
cate dryer to avoid extremes of heat and cold from ambi-
ent or other conditions. Avoid locating the dryer outside or
where exposed to the elements.
8.2 LOCATING AND MOUNTING
Lift the dryer only by the lifting points indicated by the lift-
ing labels on the dryer.
Bolt the dryer to the foundation using the bolt holes provid-
ed in the base frame. Anchor bolts should project a mini-
mum of 3.5 inches above the foundation. Refer to section
12, General Arrangement Drawings, for details.
8.3 PIPING
Pipe the compressed air lines to the inlet and outlet con-
nections. Locate the prefi lters as close as possible to the
dryer. Ensure the positioning allows for ease of servicing.
Refer to the General Arrangement drawing.
Note that the wet air inlet is at the dryer’s lower manifold,
while the dry air outlet is at the dryer’s upper manifold.
In situations where air supply is required 24 hours a day
(where it is undesirable to interrupt the airfl ow), a three
valve by-pass system is recommended to bypass the
dryer. Use the fewest elbows necessary to keep pressure
drop at a minimum.
Once all piping has been connected, all joints, including
those on the dryer, should be soap bubble tested at line
pressure to ensure no joints have been damaged in transit
and during site placement. All installed piping must be
self-supported.
8.4 FILTRATION
It is important that a prefi lter and an afterfi lter be provided
in your dryer installation.
Coalescing prefi lters, located before the dryer, protect
desiccant beds from contamination by oil, entrained wa-
ter, pipe scale, etc., thereby, extending dryer desiccant life.
Locate prefi lters as close to dryer as possible.
It is recommended that a mechanical separator be in-
stalled immediately preceding the prefi lter to remove bulk
liquid and entrained water.
Particulate afterfi lters, located after the dryer, help elimi-
nate the possibility of desiccant dust carryover into the air
system.
8.5 ELECTRICAL CONNECTION
Make all electrical connections to the dryer as shown on
the wiring diagram. Care must be taken to connect the
proper voltages.
Size fi eld connection knock-out for the conduit fi tting re-
quired by the NEC.
8.0 INSTALLATION AND START-UP
!
NOTICE
The standard dryer is not rated for any gas other than
air.
!
NOTICE
ZEKS recommends the muffl ers be cleaned after initial
start-up to remove any desiccant dust generated during
dryer shipment. After running the dryer for the initial 30 min-
ute period, de-energize/depressurize the dryer and remove
the muffl ers. Disassemble and clean the removable insert
inside the muffl er core. Reinstall the muffl ers prior to oper-
ating dryer.
!
NOTICE
All ZPA dryers must have proper fi ltration. Liquid water
and oil must be removed before compressed air enters
the dryer. Ensure separators, prefi lters and drains are
in good working order. Failure to do so will void war-
ranty.
!
NOTICE
Dryer must be grounded with the full size ground wire
connected to an earth ground.
!
NOTICE
Dryer must be fused according to NEC with the size fuse
listed on the dryer serial nameplate, or on specifi cation
sheet in Technical Manual.
