Advantages of DXair Technology
Quiet Operation
• Least amount of refrigerant per ton
All panels are insulated with ½" thick, 1.5 lb./cu. ft.
dual-density fiberglass insulation for both thermal
insulation and noise reduction. Noise reduction is a critical
consideration of the unit’s design. For vibration isolation,
all compressors are mounted on rubber grommets.
Compressor rubber isolators are necessary in preventing
vibration transmission from the compressor to the unit
cabinet and duct work. Vertical cabinets have an insulated
divider panel between the blower compartment and the
compressor section to minimize the transmission of
compressor noise, and to permit operational service testing
without air bypass.
• Field cleanable evaporator coils

FEATURES, FUNCTIONS AND
BENEFITS
Cabinet
The EC Model cabinetry is constructed using heavy-gauge,
G-60 galvanized steel. This type of steel provides superior
corrosion protection for units installed indoors.
All interior surfaces are lined with ½" thick, 1.5 lb./cu.ft.
dual-density, fiberglass insulation for thermal insulation
and acoustical attenuation. This insulation is noncombustible, non-hydroscopic and does not support
fungal growth. The unit insulation also meets NFPA 90A
and 90B for fire protection, UL 181 for erosion, and is
certified to meet the GreenGuard™ Indoor Air Quality
Standard for Low Emitting Products.
Protection against corrosion is a feature in the Large EC
Model. A stainless steel drain pan will last the lifetime of
the unit and resist corrosion and cracking that may occur
with painted steel, galvanized steel or plastic materials.
Filter Racks and Options
Two-sided filter racks accommodating a 1" filter are
standard on all EC units. A two-sided 2" filter rack is
optional to accommodate a nominal 1" or a 2" thick filter.
Four sided filter racks are available as an option and
minimize unfiltered air from entering the unit. Filter doors
allow for easy routine maintenance and changing of the air
filter. A 1" return duct collar is integral to the filter rack
eliminating the need for field mounted duct collars. Units
are shipped with a standard MERV-5 1" construction filter.
8
Blower and Motor
All fan assemblies are belt-driven double width, double
inlet (DWDI), forward curved, and precisely balanced to
ensure smooth operation. The blower housing and fan
wheels are designed for quiet, low velocity operation,
which helps keep high frequency fan wheel noise to a
minimum. The fan motors are 1725 or 3450 RPM, 56
frame sealed ball bearing type, permanently lubricated and
have thermal overload protection.
Evaporator Coil and DuoGuard™ (Option)
Air handling sections come standard with a copper tube
aluminum fin evaporator coil. Available as an option is the
DuoGuard™ evaporator coil protection system.
DuoGuard™ Protection® - Tin Electro-Plated Copper
Tubing with High-Tech Polymer Coated Aluminum Fins will
aid in protecting the evaporator coil from most forms of
corrosive elements in the airstream. The tin plating
provides a best-in-class protection of the copper tubing
from formicary corrosion while the fin coating provides
protection against salt spray and other corrosive elements.
DuoGuard™ protected coils are able to exceed 1000 hours
salt spray per ASTM standard B-117.
Refrigerant Circuit
EC Models are designed using the optimum combination
of compressor and field cleanable coils to provide peak
performance.
Heavy-duty compressors are used in all units. Scroll or
reciprocating compressors offer optimum performance for
each unit size.

Variable Frequency
Drive (Optional)
Refrigerant to water heat exchangers are coaxial tube-intube type providing a robust construction, ensuring years of
trouble free operation. Coaxial coils are selected and
designed for peak performance, offering the best
combination of low water pressure drop and maximum heat
transfer in both the cooling and heating modes. Standard
coaxial coils have a copper interior water tube and a steel
outer shell. Optional cupro-nickel coils are available for
applications where the water is of lower quality.
Scroll and
Reciprocating Compressors
High and low pressure switches are factory installed in the
refrigerant circuit, protecting the unit against high pressure
conditions or loss of refrigerant charge.
Schrader service valves are standard on the high and low
pressure lines of all units, allowing connection of gauges
for service diagnostics and to evacuate, reclaim or recharge
refrigerant into the system. Optional Schrader valves are
available with the connection to field installed water
regulating valves.
Air coils are state of the art, employing lanced fin and rifled
tubing for maximum heat transfer. Large face areas result
in lower face velocity reducing sound while ensuring high
latent heat removal for maximum dehumidification in the
cooling mode.
Thermal Expansion Valves come standard on the EC and
are designed to vary the flow of refrigerant depending on
the load. TXV’s provide unit optimization and a more stable
control over a wider range of operating conditions.
EC Model units are rated to withstand 600 PSIG working
refrigerant pressure and 400 PSIG working water pressure.
All EC Model are provided with filter driers to ensure that no

UNIT PROTECTION MODULE (UPM)
Each EC Model is built in the factory with a Unit Protection
Module (UPM) that controls the unit operation and monitors
the safety controls that protect the unit. The UPM interfaces
with the thermostat or human-machine interface (HMI).
The main purpose of the UPM is to protect the compressor
by monitoring the different states of switches and sensors.
This module provides time delays and protects the unit
against freezing of the water-to-refrigerant and air-torefrigerant heat exchangers as well as condensate overflow.
This level of protection helps provide the peace of mind that
comes with offering DXair products to the customer.
UPM Control Board Features
• Condensate Overflow Protection — The UPM controller
continuously monitors the drain pan for high condensate
water level, and if this exceeds normal operating levels, the
compressor operation is interrupted to protect against drain
pan overflow.
• Anti-Short Cycle Timer — 5 minute delay on break timer to
prevent compressor short cycling.
• Random Start — Each controller has a unique random start
delay ranging from 270 to 300 seconds after power is applied to
the board. This will prevent the simultaneous start of multiple
units after a power outage.
• Low Pressure Bypass Timer — The low pressure switch is
bypassed for 120 seconds after a call for compressor operation
to prevent nuisance low pressure lockouts during cold
start-up.
• Brownout/Surge/Power Interruption Protection—
Prevents compressor operation should the voltage drop below
10% of unit rated value. The unit will restart once the voltage
is within tolerance and the random start has timed out.
• Malfunction (Alarm) Output — The controller has a set of
contacts for remote fault indication. This can be either a
10
UPM Control Board
steady output or can be set to pulse with the fault code.
Two connections are available; one to provide a 24 volt
output, the other to provide a dry contact.
• Test Service Mode — A dip switch setting is provided to
reduce all time delay settings to 10 seconds maximum
during troubleshooting for verification of unit operation.
• LED Fault Indication (2-Stage) — Two LED indicators are
provided as follows:
• Green: Power LED indicates 18-30 VAC present at
the board.
• Red: Fault indicator with blink codes identifying the
particular fault. This information is available via the
malfunction (alarm) output contacts.
1 Blink - High Pressure
2 Blinks - Low Pressure
3 Blinks - High Pressure (2-stage)
4 Blinks - Low Pressure (2-stage)
5 Blinks - Low Fluid Temperature
6 Blinks - Condensate Overflow
7 Blinks - Brownout condition
• Intelligent Reset—If a fault condition is initiated, the
5 minute delay on break time period is initiated and
the unit will restart after this delay expires. The UPM is
configurable for either 2 or 4 fault occurrences before
going into a hard lockout. The selection is made
through a DIP switch setting on the board. If the fault
condition still exists or reoccurs twice or four times
within one hour, the unit will go into a hard lockout
and requires a manual lockout reset. A condensate
overflow fault will, however, put the unit into a hard
lockout immediately.
• Lockout Reset—A hard lockout can be reset by turning the
unit thermostat off and then back on or by shutting off unit
power at the circuit breaker. The method of reset is selectable
by the dip switch on the board.

Take-Apart Construction
Where there is a restriction in the available height to the
access of a mechanical space, the EC unit is available in a
take-apart construction. The unit is built so that the
condensing section can be field separated from the air
handling section and both transported separately into the
mechanical space where they would be reassembled. The unit
is built with the refrigerant lines in both sections capped and
with a holding charge of nitrogen in each section. It is the
installer’s responsibility to reassemble the unit and join all
refrigerant lines, evacuate and charge the refrigerant system.
The blower motor, condensate sensor and freeze protection
wires would be wired to the condensing section. The takeapart option is only available on vertical units, allow for an
increase of approximately 3" in the height of the unit.
Energy Management Switch (EMS)
This switch allows you to connect to an energy management
system that can turn the unit off and on. Energy
management systems are commonly used by individual
commercial entities to monitor, measure, and control their
Subject to change without prior notice Revised 07 - 16
The function of the flow proving switch is to prevent or stop
compressor operation should the condenser fluid supply fail.
This will prevent the unit from locking out on a safety
requiring a manual reset to restart. The switch is piped
between the liquid entering and leaving connections. Should
the pressure drop fall below set value, the switch will open
de-energizing the DPS relay, thereby stopping the compressor.
The blower operation will not be affected by this option.
Hot Gas Reheat
Hot gas reheat (HGR) allows the user to control space
temperature and humidity levels within the conditioned
space. Excessive moisture in the space can promote mold
growth leading to damage in the structure or interior
surfaces, as well as reducing the air quality and creating an
unhealthy environment.
Possible causes of excess humidity could be by the unit having
to operate under a widely varying load, an oversized short
cycling unit, a high percentage of unconditioned outside air
being introduced into the space, a high latent load in the
space or any location where humidity infiltration is a problem.
The HGR unit is controlled by wall mounted thermostat
and humidistat device(s) to control temperature and
humidity. By utilizing a humidistat in addition to the
thermostat, we are able to monitor the humidity levels in
the space as well. The HGR option allows cooling and
dehumidification to satisfy both the thermostat and
humidistat while preventing over cooling of the space
while in the dehumidification mode.
Once the thermostat reaches set point temperature and
the humidity is above set point, the unit controller will
energize the reheat valve operating the unit in hot gas
reheat mode, first cooling and dehumidifying, then
reheating the air using hot refrigerant gas before delivering
it to the space. By reheating the air along a constant
sensible heat line, the relative humidity of the leaving air is
reduced. This option offers significant energy savings over
11
EC SERIES POOL DEHUMIDIFIERS
the traditional means of reheating air with electric or hot
water heating coils.
In the reheat mode, the compressor discharge gas is diverted
through the reheat valve to the reheat coil which is located
downstream of the cooling coil. The superheated refrigerant
gas reheats the air leaving the cooling coil. The hot refrigerant
gas then passes though the water to refrigerant coil where it
is condensed to a liquid. From this point the rest of the cooling
cycle is completed. There are two check valves to prevent
refrigerant flow into the reheat coil during standard cooling
cycles. A small copper bleeder line is connected to the outlet
line of the reheat coil and between the expansion valve outlet
and distributor to the air coil. This line is necessary to let any
liquid/oil that may have migrated to the reheat coil during
reheat to escape during standard cooling mode.
Hot Gas Reheat Sequence of Operation –
On/Off Control
The sequence of operation in the cooling
and heating
Caution
mode is the same.
In the reheat mode, on a call from the humidistat, the
reheat relay coil is energized through the “H” circuit. The
cooling relay remains de-energized enabling the reheat
solenoid. The blower relay, reversing valve and compressor
contactor are energized through contacts on the reheat
relay. (Note: The reheat mode always operates in the
cooling mode.) Should the temperature in the space
increase above set point, the compressor terminal Y is
energized, which will de-energize the reheat valve putting
the unit into straight cooling mode. A call for cooling will
always take precedence over hot gas reheat.
Special Considerations
Some applications require special attention to maximize
the performance of the hot gas reheat function.
Indoor Pool Dehumidifying During
Winter Months
It is important to remember that when in the reheat/
dehumidification mode the pool dehumidifier is cooling and
reheating. A secondary means of heating the space during
the dehumidification mode should be provided. The indoor
space temperature must be kept at least 2° F above the pool
water temperature, with normal settings of 80°F to 84°F
pool water temperature, 82°F to 86°F air temperature at
50-60 percent relative humidity. If this is not done the warm
pool water attempts to heat the space and the humidity
levels increase exponentially. The dehumidifier is normally
sized to handle the design latent load moisture removal.
Protective coatings such as Bronze Glow
Coating are highly recommended for all pool
applications, due to the highly corrosive
chemical environment.
Hot Gas Reheat Control Options
There are several ways to control pool dehumidifier with
hot gas reheat. You should choose the means that best
suits your specific application. Please refer to the Hot Gas
Reheat wiring diagrams for typical thermostat wiring. Most
compatible thermostats in conjunction with a humidistat
are acceptable for use.
“O” output for reversing valve energized in
cooling mode is required.
Combination thermostat/humidistat are also available.

must be provided around the unit for service personnel to
perform maintenance or repair.
Units are not designed for outdoor installation. Avoid
locations where the unit may be exposed to freezing
conditions or where the humidity levels could cause
condensation on the unit panels for example when
exposed to outdoor ambient conditions.

Horizontal Unit Installation
Large horizontal units are supplied with angle or box
section supports for suspension. Field supplied hanging
rods, spring or rubber isolators should be used to isolate
the unit from the building structure to prevent vibration
transmission to the building. Units should be located
directly below a structural member so that it is securely
anchored.
A horizontal unit should be positioned to allow for removal
of the filters and access panels. Allow at least 24"
clearance on each side of the unit for service and 36" in
front of the unit for maintenance access. The filter needs to
be slid out and sufficient space must be provided to allow
this.
Do not install the unit above any piping or electrical
raceways. The unit should be able to be removed to the
floor without major rearrangement of other mechanical or
ceiling components.

Ductwork and
Sound Attenuation Considerations
Lining the first five feet of
supply duct reduces noise
Turns attenuate
blower noise
Take-offs should be at least
five feet away from the
plenum
Figure 9 Supply Air Ducting
Sound is becoming an increasingly important factor in all HVAC
installations. The EC Model has been designed to minimize
sound, but sound acoustical design plays an important part of the
sound level in the space.
Most of the problems associated with HVAC generated
sound can be avoided by paying close attention to duct
design and equipment placement.
A discharge flange is provided on all horizontal unit models
for fastening of ductwork. We recommend using a flexible
collar between the discharge flange and the duct
transformation to reduce vibration transmission from the
cabinet and to simplify disconnection of the unit from the
ceiling ductwork.

Figure 10 Return Air Ducting
Return air to the unit could be either free return or ducted.
The filter rack is provided with a 1" flange should a ducted
return be used. We recommend using a flexible collar
14
between the return flange and the duct transformation to
reduce vibration transmission from the cabinet and to simplify
disconnection of the unit from the ductwork.
Sound is transmitted down the ductwork and it is important to
avoid direct line of sight between the unit and the space, both on
the return or supply side. To accomplish this, design the duct runs
with two 90° turns.
As a general recommendation, duct interiors should have an
acoustic / thermal lining of least 1/2" thick over the entire duct run
or a minimum of the first 5 feet of the supply trunk. DXair
recommends fiber-free insulation for ducts and internally within
the unit (as an option).
Line the last five diameters of duct before each outlet with a
one-inch thick sound blanket. Line elbows and transition pieces,
as well as a short distance upstream and downstream of the
fittings.
Elbows, tees and dampers can create turbulence or distortion in
the airflow. Using aerodynamic fittings will help in reducing this
effect. Place a straight length of duct, 5 to 10 times the duct
width, before the next fitting to smooth out airflow.
Diffusers that are located in the bottom of a trunk duct can also
produce noise.
Balancing dampers should be located several duct widths
upstream from an air outlet.
Ductwork should be mounted and supported using isolation
devices that absorb vibration.
Applications such as a hotel that uses single duct discharges
are susceptible to noise. These applications typically have low
static pressures and short duct lengths. In these applications
the discharge duct must be fully lined and have a square elbow
without turning vanes. A velocity not exceeding 500 to 600
fpm is recommended. Return air for these applications should
enter through a sidewall grille and route up the stud space to a
ceiling plenum.
For horizontal systems mounted in the ceiling plenum, an
insulated return plenum is sometimes placed at the return air
opening to further attenuate line-of-sight sound transmission
through return openings. A secondary drain pan is required under
all above grade installations.

PIPING
Condensate Drain Piping
Condensate piping can be made of steel, copper or PVC
pipe. In most cases, PVC pipe eliminates the need to wrap
insulation around the pipe to prevent sweating.
All EC Models provide a standard FPT condensate drain
connection installed in the unit (reference install manual for
exact diameter based on capacity of unit). The condensate
piping must be trapped at the unit and pitched away from
the unit not less than ¼" per foot. A vent is required after
the trap so that the condensate will drain away from the
unit. The vent can also act as a cleanout if the trap becomes
clogged. The condensate drain should not be directly piped
to a drain/waste/vent stack. See local codes for the correct
application of condensate piping to drains.
OPERATING LIMITS
EC Models are capable of operating over a wide range of
conditions.
• Maximum and minimum fluid conditions are at unit
rated flow rate.

• Maximum and minimum operating limits may not
be combined. If one value is at either maximum or
minimum, the other two should be at normal
operating range.
EQUIPMENT SELECTION
To ensure that you get the optimal performance from
your DXair dehumidifier. it is important that they be
selected accurately to match your design conditions
and criteria.
Prior to making equipment selections the zone
conditions need to be determined.

Cabinets shall have separate holes and knockouts for
entrance of line voltage and low voltage control wiring.
Supply and return liquid connections shall be copper FPT
fittings and shall be securely mounted flush to the cabinet
allowing for connection to a flexible hose without the use
of a back-up wrench. Liquid connections which protrude
through the cabinet shall not be allowed.
Condensate overflow protection shall be provided as
standard for horizontal and vertical package units.
Fan and Motor Assembly
The fan(s) shall be belt driven DWDI forward curved type
with dynamically balanced wheel(s). The fan motor(s) shall
be 1725 or 3450 RPM 56 frame sealed ball bearing type.
The motor(s) shall be permanently lubricated and have
thermal overload protection.
The fan and motor assembly must be capable of
overcoming the external static pressures as shown on the
schedule. External static pressure rating of the unit shall be
based on a wet coil. Ratings based on a dry coil shall NOT
be acceptable.
Refrigerant Circuit
Units shall use R-410A refrigerant. Units that use R-22
refrigerant shall not be allowed.
All units shall have a factory sealed and fully charged
refrigerant circuit with the following components:
A. Hermetic compressor: Hermetic reciprocating, or scroll
compressors shall be specifically designed for R-410A
refrigerant and shall be internally sprung (if
reciprocating), externally isolated and with thermal
overload protection.

B. Refrigerant metering thermal expansion valves.
Electrical
C. Finned tube refrigerant to air heat exchanger.
Refrigerant to air heat exchangers shall utilize
enhanced aluminum fins and rifled copper tube
construction rated to withstand 600 PSIG refrigerant
working pressure. All air coils shall have non-ferrous
aluminum end plates.
A control box shall be located within the unit and shall
contain a transformer, controls for the compressor,
reversing valve and fan motor operation and shall have a
terminal block for low voltage field wiring connections.
The transformer shall be rated for a minimum 100VA. All
units shall be name-plated for use with time delay fuses or
HACR circuit breakers. Unit controls shall be 24 volts.
D. DuoGuard™ Coil Protection System – A corrosion
protection option for refrigerant to air heat exchangers
that features tin plating of the copper tubing and
coating of the aluminum fins with a protective film.
The tin plating shall provide best in class protection of
the copper tubing from formicary corrosion while the
fin coating provides protection against salt spray and
other corrosive elements. DuoGuard™ protected coils
will exceed 1000 hours salt spray per ASTM standard
B-117.
E. Coaxial (tube in tube) refrigerant to liquid heat
exchanger. Refrigerant to liquid heat exchangers shall
be of copper inner water tube and steel outer
refrigerant tube design rated to withstand 600 PSIG
working refrigerant pressure and 400 PSIG working
liquid pressure.
F. Cupro-nickel water coil (option) – The refrigerant to
liquid heat exchanger shall be of cupro-nickel inner
liquid tube construction.
G. Safety controls including both a high pressure and low
pressure switch shall be provided on both circuits.
Temperature sensors shall not replace these safety
switches. See the controls section of this specification
for additional information.
H. Access fittings shall be factory installed on high and
low pressure refrigerant lines to facilitate field service.
I.
Activation of any safety device shall prevent
compressor operation via a lockout circuit, in the
affected circuit. The lockout circuit shall be reset at the
thermostat or at the contractor supplied disconnect
switch. Units which may be reset at the disconnect
switch only shall not be acceptable. A condensate
alarm on package units shall prevent both compressors
from operating.
J. Service valves on split system condensing sections
must incorporate a Schrader service port to facilitate
field service.

12. Automatic intelligent reset. Unit shall automatically
reset after a safety shut down and restart the unit after
the anti-short cycle timer and random start timer
expire. Should a fault re-occur within 60 minutes after
reset, then a permanent lockout will occur. Reset
attempts shall be selectable for either 2 or 4 tries.
Condensate overflow shall put the unit into a hard
lockout on the first fault.
13. Ability to defeat time delays for servicing.
14. A light emitting diode (LED) to indicate safety alarms
shall be provided for each circuit. The LED shall
annunciate the following alarms: high refrigerant
pressure, low refrigerant pressure, low liquid
temperature, a high level of condensate in the drain
pan, or brown out/surge/ power interruption. The LED
will display each fault condition as soon as the fault
occurs. If a permanent lockout occurs, then the fault
LED will display the type of fault until the unit is reset.
15. 1.ETL listed, and RFI, ESD, and transient protected.
Options
A. Extra quiet construction: Optional compressor blankets
shall be provided on units, for additional sound
attenuation.
B. Hot Gas Reheat: Vertical or horizontal package units as
noted on the schedule shall be equipped with optional
Hot Gas Reheat (HGRH). HGRH shall be either on/off
control as noted in the specifications.
On/Off HGRH shall be controlled by a humidistat
connected to the unit H terminal and shall start the unit in
the reheat mode should the humidity be above setpoint
once the thermostat control is satisfied.

UNIT LOCATION
SOUND
DO NOT STORE pool equipment and/or pool chemicals in
the mechanical space designed for the DXair
Dehumidification System. Failure to follow these
instructions may void your warranty as chemicals are highly
corrosive and destructive to any HVAC system.
Sound is becoming an increasingly important factor in all
HVAC Installations. Most of the problems associated with
HVAC generated noise can be avoided by paying close
attention to the equipment placement in properly designed
mechanical space and the duct work/air delivery system.
Any mechanical device will, at some point in time, require
servicing and repair. With this in mind, sufficient mechanical
space must be designed and sufficient clearances around
each horizontal and vertical unit must be provided. 30-36”
clearance is required around the unit and access panels. This
equipment is not recommended to be located or installed in
the pool room above an open pool, closets, crawl spaces
without the proper access, “trap” door type accessible
spaces. The proper space must be allocated to install the
system, clearances required, peripheral installation,
ductwork and bypass installation. Failure to provide the
appropriate space may void your warranty.
Proper clearances for installation of peripherals and space
must be allowed for the proper duct work installation.
Choking down ductwork in this mechanical space will have
negative air flow effects for your pool room. Sufficient space
must be provided for filter replacement and access to the
compressors. Units should be set on a piece of rubber,
neoprene or other vibration absorbing material at least 1/3½” thick. The pad should extend ¾” over the entire base of
the unit. Avoid direct line of sight to the unit. Install a sound
baffle over any door that has a return air grille.
Horizontal units are typically suspended above the ceiling
by four (field supplied) 3/8” threaded rods fastened to the
unit by factory supplier hanger bracket kits. This kit
includes rubber isolators to help prevent transmission of
vibration and noise to the building structure. Units should
be located directly below a structural member, so that it is
securely anchored. A horizontal unit always requires the
proper clearances (18” clearance on either side of the unit
for service and 36” in the front of the unit for maintenance
access). The filter needs to be slid out and sufficient space
must be provided to allow this.
Do not install any unit above any piping or electrical
raceways. This unit must be able to be removed at any time
without major re-arrangement of other mechanical or
ceiling components.

NEGATIVE PRESSURE
A negative pressure fan must be installed in the pool room
to prevent moisture migration. This is mandatory for all
indoor pool room environments.
DUCT AIR DELIVERY SYSTEM
DXair requires a very high standard of duct systems for our
equipment. All specifications for the air delivery system
must be met and all ASHRAE and ACCA Manuals
pertaining to properly sized duct work must be followed.
Air delivery is critical to these structures. A continuous loop
of duct is recommended at a .20 static on supply and a .07
on one high return air. All diffusers should be double
deflection and moving air 6-12” from all glass or surfaces
that are prone to condensation. Diffusers are not designed
“blowing down”, “blowing over” a pool area, they must
be deflected at surfaces that can reach Dew Point
Temperature. Diffusers are not built into the walls between
windows blowing across an open pool.
We do not recommend blowing air across an open pool ;
this serves to increase the evaporation of pool water and
create a chill effect on the patrons. Blowing air across an
open pool does not resolve chloramine issues; this is a
water quality issue that must be addressed by those proper
balancing of pool water at all times; it is not a HVAC issue.
Square throats and restrictions in the air delivery system
must be minimized. If square throats are used, the proper
elbows/radius and turning vanes are required. The more
restrictive air flow in a duct system, the less likely this system
will control the environment properly and may place
additional stress due to lack of air flow on the system itself.
No fiberboard duct or flex duct should be used in these
systems unless approved in writing by DXair Engineering.
All skylights must be addressed with air flow. If ducting
cannot reach these areas, ceiling fans blowing up must be
installed between the skylights to move air into them and
prevent condensation.
