FOUR STEPS TO FRESH, COOL AIR DURING THE COOLING SEASON:
LIFTING
FIGURE 1.
Lift modules only with lugs located at the base of
each module. Do not use a forklift.
To off load each of the system’s modules, lift only
with the lugs located at the base of each module
(
FIGURE 1
). Do NOT lift with a forklift. Spreader bars
must be used to hoist sections to avoid damaging
the enclosure (
FIGURE 2
).

STEP 1
Hot, humid outside air is drawn into the
Ascendant system passing through pre-filters
before entering conditioning components.
Hot, humid outside air is drawn into the Ascendant
system passing through pre-filters before entering
conditioning components.
STEP 2
Outside air is cooled and dehumidified before
entering the Active Desiccant wheel.
Outside air is heated to desired temperature to
lower the relative humidity of the air before entering
the Active Desiccant wheel.
STEP 3
The moisture in the air is adsorbed by the
desiccant producing dry air. A modulating damper
allows a portion of the supply air to bypass the
wheel.
The adsorbed moisture is desorbed by heated
air regenerating the wheel’s ability to remove
moisture.
STEP 4
(OPTIONAL) Supply air can be cooled using
post-cooling coils and further filtered with high
efficiency or HEPA filters.
Warm, humidified regeneration air is exhausted
from system.
Chokers need to be adjustable so that the unit is
level when it is picked up and, more importantly,
set down. Setting the unit down on one corner could
cause the unit to rack. Lever chain pullers are useful
for this purpose.
RECEIVING
1)
A packing list is supplied with each shipped
system (See
FIGURE 3
). The list should be
compared with arriving shipments to ensure that
all modules and equipment have been delivered
in good condition. Visible damage should be
noted on the trucker’s bill of lading when
receiving the unit.
2)
Prior to leaving the plant, each system has been
tested. You will find the quality assurance label
on the inside of the electric box cover.
3)
If the modules are to be stored for more than
three days prior to installation, a visual
inspection of all equipment is necessary. Report
missing or damaged equipment to FläktGroup
SEMCO immediately. Freight claims are difficult
to justify long after delivery has been completed.
(If the modules are to be stored, see
4)
Modules accumulate dust, dirt and corrosive
matter (like salt) during shipment to the
installation, site on open trailers, and are

An envelope with the packing list and other
pertinent information is found inside the electrical box.
