Introduction

FORM TPM3-EG1 (518)

The TempMaster® OmniElite™ Single Package Units –
designed to meet the demands of the market for today and
tomorrow.

Better Economy...

Lower total cost of ownership

• TempMaster provides a standard product offering that meets the latest ASHRAE

90.1 energy efciency requirements.

• Unique compressor staging provides quick response to cooling needs and provides
multiple steps of capacity for high part load efciency.

• Fully modulating gas heat and greater steps of capacity control offer superior off­design performance while maintaining optimum occupant comfort.

• Accurate ventilation control ensures that no more than the proper amount of ventila­tion air is utilized. This avoids the energy cost of conditioning excess outside air and

simultaneously monitors all other unit functions for maximized energy efciency.

• Flexible design congurations simplify the design process and allows the TempMas-
ter OmniElite to be applied to virtually any building application.

• Accessibility through double-wall access doors, spacious compartments and sup-

portive oors improves serviceability.

LD07431

The single package unit user interface uses micro­processor logic to optimize operation of the Temp­Master OmniElite single package unit.

Better Ecology...

Indoor air quality (IAQ) features for the indoor environment

• A double-sloped stainless steel drain pan with a single drain con­nection ensures that all condensate is voided from the drain pan. It
is also visible and accessible for periodic inspection and cleaning re-

quired by the ASHRAE 62 IAQ standard.

• Double-wall construction of the roof, oor, doors, and walls pre­vents insulation bers from entering the conditioned air. The inner liner

also facilitates periodic cleaning of the unit to prevent harmful build-up
of bacteria or contaminants.

• The single package unit control center uses microprocessor
logic to analyze and optimize ventilation decisions and perform de-

mand ventilation, airow compensation, and airow measurement to
maintain the air quality at a healthy level.

Features and Benefits (Cont'd)

Modulating Powered Exhaust with a VFD – This option consists of a VFD to modulate the
speed of the exhaust fan to control the flow of exhaust air. The VFD control logic is based
on the building static pressure setpoint within the single package unit controller. The static
pressure transducer is provided in the return plenum of the single package unit, and 5/16­inch or 1/4-inch plastic tubing and static pressure sensor must be supplied by others and
installed in a representative location in the building.

Powered Return Fan with Exhaust – This option uses single width, single inlet (SWSI)
plenum fan(s) to control building pressure. The fan motors are driven by a VFD to maintain
a constant return plenum pressure. An exhaust hood with a modulating control damper
is used to maintain building pressure via the building static pressure. The static pressure
transducer is provided in the return plenum of the single package unit, and 5/16-inch or
1/4-inch plastic tubing and static pressure sensor must be supplied by others and installed
in a representative location in the building. The powered return fan is also available with­out the exhaust capabilities. For units with no exhaust capabilities, the HVAC system must
provide alternate means of controlling building pressure.

SUPPLY FAN OPTIONS

Double Width, Double Inlet (DWDI) Airfoil Supply Fan – The standard airfoil blade sup-

ply fan is available on all models for higher static conditions. This offers higher efficiency
and lower sound in certain applications.

Fan Skid Isolation – The entire supply fan assembly is isolated from the unit base with
either 1-inch (standard) or 2-inch deflection springs with seismic restraints.

Supply and Exhaust Fan Motors – Premium efficiency open drip-proof (ODP) and pre­mium efficiency total enclosed fan-cooled (TEFC) motors are available all meeting the
Energy Policy Act of 1992 (EPACT).

Supply Fan VFD and Manual Bypass – For VAV applications, VFDs are provided to
modulate air flow. Optional manual bypass can also be provided to allow full airflow in the
event of a VFD failure.

Direct Drive Plenum (DDP) Fan – A direct drive plenum (DDP) supply fan provides out­standing reliability and efficiency, eliminating the possibility of conditioned air supply inter­ruption due to a broken belt and the pollution of conditioned air with belt dust. The supply

fan can be optionally equipped with a piezo ring to precisely measure the amount of air

delivered to the conditioned space. The speed of the supply fan is controlled by a VFD.

EVAPORATOR SECTION

Double Sloped Stainless Steel Drain Pan – The TempMaster OmniElite’s stainless steel

drain pan is factory-mounted and installed on every unit. A condensate drain trap is need­ed and must be provided and installed in the field by others.

FORM TPM3-EG1 (518)

Double-Wall Construction – Double-wall construction is the standard construction of the
TempMaster OmniElite and incorporates powder coated pre-fabricated outer panels and
corner post for maximum exterior surface protection.

Factory Shrink-Wrap – All TempMaster OmniElite single package units are shipped from
the factory with factory-fresh shrink-wrap packaging. No longer does the contractor need
to worry about dirt and debris clogging up condenser coils or moisture leaking into the air
handler on the units way to the job site or rigging yard.

Copper Fins – For more extreme climates that aggressively can attack aluminum, copper
tube evaporator coils with copper fins are available. (This is not recommended for units in
areas where they may be exposed to acid rain or environments where ammonia is present.)

CONDENSER FEATURES AND OPTIONS

Scroll Compressors – Reliable, efficient, trouble-free operation is the true measure of

a single package unit’s value. That’s why TempMaster OmniElite single package units
use established scroll compressor technology to deliver dependable, economical perfor­mance in a wide range of applications. With the TempMaster OmniElite single package
units, you get the latest generation of compressor enhancements added to the scroll’s
inherent strengths. The simplicity of a hermetic scroll compressor allows the use of fewer
moving parts to minimize breakdown.

Compressor Circuiting – The TempMaster OmniElite is designed so that only two scroll
compressors are in tandem within one refrigeration circuit. This means more reliable com-

pressors, and less equipment down time. With multiple circuits, if a compressor should

ever fail on one circuit, the other circuit/s will remain operational to work to maintain oc­cupied loads. The TempMaster OmniElite system has three circuits in a unit.

Compressor Staging - The TempMaster OmniElite refrigeration system is equipped with
a unique staging algorithm. On first call for cooling the system calculates the amount of

cooling capacity needed by the space and automatically brings on enough cooling capac­ity to meet this calculated need. Comfort cooling is provided quickly without the lag inher­ent to staging on additional compressors to meet a high demand. Additionally, due to a
three independent circuit design with two compressors on each circuit, the TempMaster
OmniElite can provide superior granularity in terms of staging, which translates to best in
class part load efficiency or IEER.

Condenser Fan Motors – The condenser fan motors used on the TempMaster OmniElite
unit are totally enclosed air over (TEAO) to provide maximum durability through any sea­son.

Replaceable Core Liquid Line Driers – Liquid line driers are standard on the TempMas-
ter OmniElite single package unit.

Post-Coated Condenser Coil Fins – Technicoat coil-coating process used on condenser
coils for seashore and other corrosive applications (with the exception of strong alkalis,
oxidizers, wet bromide, chlorine, and fluorine in concentrations greater than 100 ppm).

Compressor Sound Blankets – Optional compressor acoustic sound blankets are avail­able for sound sensitive applications.

for use with wood nailer (by others). Roof curb supports the entire perimeter of the unit.

Partial Perimeter Roof Curbs – This option includes a knock-down 14-inch high roof
curb for use with wood nailer (by others). Roof curb supports the air handling section with
a separate support under the condenser end.

CABINET FEATURES AND OPTIONS

Double-Wall Access Doors - Full-sized access doors provide easy access into the unit

for routine maintenance and inspection. Solid wall liners encase insulation and prevent
damage and erosion into the airstream.

Diffuser Section – An optional diffuser section is available downstream of the supply
fan in the extended discharge plenum cabinet option. The diffuser section distributes the
airflow from the fan evenly across the downstream filter bank to optimize filter life and
effectiveness. The diffuser design is optimized to provide uniform flow at minimal airside
pressure loss.

Downstream Final Filter Rack – A 90–95% efficient MERV 14, 12-inch rigid filter rack
and filters shall be provided downstream of the supply fan and diffuser segment for hospi­tal applications. A magnahelic pressure gauge is included and visible from the outside of
the unit for servicing and code compliance.

Blank Section – A blank section shall be provided downstream of the supply fan and dif­fuser section.

ACCESSORIES

Filter Switch – An optional dirty filter alarm can be provided that will provide an alarm

when the filters require cleaning.

Magnahelic Filter Pressure Gauge – On units equipped with downstream filtration, a

magnahelic filter gauge is included and visible on the exterior of the unit. The filter gauge
measures the air pressure drop for through the rigid filter bank to indicate when replace-

ment is required.

Application Data

GENERAL

The TempMaster® OmniElite™ air conditioning units are designed for outdoor installation.
When selecting a site for installation, be guided by the following conditions:

• Unit must be installed on a level surface.

• For the outdoor location of the unit, select a place having a minimum sun exposure

and an adequate supply of fresh air for the condenser.

• Also avoid locations beneath windows or between structures.

• Optional condenser coil protection should be used for seashore locations or other harsh
environments.

• The unit should be installed on a roof that is structurally strong enough to support the

weight of the unit with a minimum of deection. It is recommended that the unit(s) be

installed not more than 15 feet from a main support beam to provide proper structural
support and to minimize the transmission of sound and vibration. Ideally, the center
of gravity should be located over a structural support or building column.

• Location of unit(s) should also be away from building ue stacks or exhaust ventila­tors to prevent possible reintroduction of contaminated air through the outside air
intakes.

• Be sure the supporting structures will not obstruct the duct, gas or wiring connec­tions.

• Proper service clearance space of 6 feet around the perimeter of the unit, 8 feet on

one side for coil servicing, and 12 feet to any adjacent units is required to eliminate

cross contamination of exhaust and outside air, and for maintenance tasks such as
coil pull and cleaning. No obstructions should be above the condensing unit section.

LOCATION

Of the many factors that can effect the location of equipment, some of the most important

to consider are structural, acoustical and service clearances. Proper attention should be

made at the design stage to ensure proper structural support. In cases where equipment
is being replaced, be aware of building design to ensure support is adequate for the ap-

plication.

The next most important consideration in applying single package units equipment is that
of sound from the equipment. Special care should be made to keep the single package

unit away from sound sensitive areas such as conference rooms, auditoriums and execu­tive offices and any other room that may have potential for tenant occupancy. Possible
locations could be above hallways, mechanical or utility rooms.

Finally, service clearances should be maintained in single package unit design to ensure
safe access to the unit. Unit clearances are designed so that technicians have enough
space between units, building walls, and edges of building to gain access safely. In cases
where space is limited, please call a local TempMaster representative for additional infor­mation.

TEMPMASTER

FORM TPM3-EG1 (518)

RIGGING

Proper rigging and handling of the equipment is mandatory during unloading and setting

it into position to retain warranty status.

Spreader bars must be used by cranes to prevent damage to the unit casing. All lifting
lugs must be used when lifting the single package unit. Fork lifts will damage the single
package unit and are not recommended.

Care must be taken to keep the unit in the upright position during rigging and to prevent dam­age to the watertight seams in the unit casing. Avoid unnecessary jarring or rough handling.

UNIT PLACEMENT

• Elevated – Elevated roof curbs or dunnage steel can be used to support the unit in

order to raise it to specic heights. When this type of placement is required, be sure
to keep unit access in mind. Cat walks or other forms of unit access may be required

to one or both sides of the unit, depending on your area of the country and the local

codes that are enforced. Please check with local ofcials to ensure the application

conforms to local codes and regulations.

• Ground Level Locations – It is important that the units be installed on a substantial

base that will not settle, causing strain on the refrigerant lines and sheet metal and
resulting in possible leaks. A one-piece concrete slab with footers extended below
the frost line is highly recommended. Additionally, the slab should be isolated from
the main building foundation to prevent noise and vibration transmission to the build­ing structure.

For ground level installations, precautions should be taken to protect the unit from
tampering by, or injury to, unauthorized persons. Erecting a fence around the unit is
common practice.

• Roof curb – TempMaster offers optional roof curbs designed specically for the

TEMPMASTER

TempMaster OmniElite footprint. These curbs come in full perimeter or open con­denser models and are shipped disassembled and require eld assembly and instal­lation. For bottom supply and return openings, the curbs have matching connections
to ease installation. A pipe chase that matches the single package unit pipe chase is
also included in the curb footprint for through-the-curb utility connections.

15

FORM TPM3-EG1 (518)

Application Data (Cont'd)

The curb should be located according to the location recommendations above, and
properly sealed to prevent moisture and air leakage into and out of the duct system.
Flexible collars should be used when connecting the ductwork to prevent unit noise
transmission and vibration into the building.

Ductwork should be supported independently of the unit.

UNIT ORIENTATION

For applications with multiple single package units located in close proximity on the roof,
the orientation of the unit may be important to reduce the potential for re-entrainment of
outside airflow. Regardless of the outside air and exhaust air openings on a unit, all single
package unit applications can permit recirculation of exhaust air to the return, if applied
improperly.

HORIZONTAL APPLICATIONS

The spectrum of applications for single package units in today’s market is continuing to
grow wider by the day. Flexibility in unit design and construction is a must in today’s mar-

ket in order to ensure safe and sound applications of HVAC equipment. The TempMaster

OmniElite has been designed for specific application of horizontal supply and return air­flow taking the guess work out of unit application by building a unit specific to these needs.
If the application calls for horizontal supply and return air, TempMaster can ship it from the
factory as a horizontal unit. This option eliminates the need for field modification of equip­ment saving time and money. The TempMaster OmniElite can support a left discharge on
all units except electric heat and/or right discharge on all cooling only units and hydronic
heat units with an extended cabinet. Return air can be brought through the front or bottom
return air inlet making the unit specific to building needs.

ECONOMIZER

The economizer section is used for ventilation of the conditioned space to maintain indoor

air quality (IAQ), and also to reduce energy consumption by using outside air cooling in lieu

of mechanical cooling. If outside air is appropriate for cooling, but not sufficient for the cool­ing demand, mechanical cooling will stage on as necessary until the cooling load is met.

Dual (comparative or differential) enthalpy operation is the most accurate and efficient
means of economizer operation. The IPU controller monitors the return and outside air
energy content, and selects the lower of the two for operation.

VARIABLE AIR VOLUME (VAV) SUPPLY AIR PRESSURE CONTROL

Traditional single package unit systems use inlet guide vanes (IGVs) for duct static pres­sure control. These control supply duct pressure by modulating dampers (introducing losses

and inefficiencies) on the inlet of the fan, open and closed. TempMaster variable frequency
drives (VFDs) offer superior fan speed control and quieter, energy efficient operation.

FIGURE 3 - TRADITIONAL OVERHEAD VARIABLE AIR VOLUME (VAV) AIR
DELIVERY SYSTEM

For variable air volume (VAV) applications, the TempMaster OmniElite unit uses a VFD
to modulate fan speed and maintain a constant duct static pressure. VFDs offer superior
control over the operation of the unit at part load, and offer the additional benefits of qui­eter and more efficient operation when compared to IGV.

BUILDING PRESSURE CONTROL SYSTEMS

Building pressure control systems are often necessary when economizers are used to
bring in outside air. Without proper building exhaust, the building may become over pres­surized. The pressure control system maintains the proper building pressure by expelling
the appropriate amount of air from the building.

Application Data (Cont'd)

Return fans – For high return static applications, such as buildings with ducted return
systems, a powered return fan may be necessary to maintain building pressure control.
TempMaster offers a powered return fan that is located in the return plenum. This fan
operates coincidentally with the supply fan and draws return air back through the return
ductwork and into a pressurized plenum. A control damper modulates to exhaust air out
of the building and maintain the building pressure. A second control damper modulates
to provide return air from the ductwork to the unit to the single package air mixing section.

The return fan configuration is available in two forms: with and without an exhaust damper.
The option with the exhaust damper provides a means of building exhaust at the unit. In
some applications, the exhaust system is located elsewhere and the single package unit

is not required to provide building exhaust. In these situations, the TempMaster OmniElite

can be offered without the exhaust damper to help reduce installed costs.

Exhaust/relief fans – In this application, a powered exhaust fan may be suitable, how­ever careful consideration of the fan type is necessary. TempMaster offers a centrifugal
powered exhaust fan to perform this function. Some manufacturers use a propeller ex-

haust fan, which cannot handle the static pressure requirements.

For systems with moderate to low return static pressure, an exhaust fan is recommended.
The benefit of the exhaust fan is that it does not run all of the time, and may facilitate com-

pliance with the ASHRAE 90.1 fan motor horsepower requirement.

The exhaust fan operates in parallel with the supply fan. In this arrangement, the supply
fan handles the full static pressure requirements of the system. For normal building pres­sure control, the exhaust fan operates to draw air from the return plenum and exhaust it
out of the building.

The exhaust fan configuration is available in two forms, modulating and non-modulating.
Modulating is the most common and recommended for the majority of applications, while
non-modulating should be used in only certain circumstances.

In the modulating exhaust system, the volume of airflow exhausted from the building is
proportional to the entering volume of outside air. Control is accomplished via either a dis­charge damper or a VFD. TempMaster recommends the use of a VFD to reduce energy
consumption, sound levels and improved reliability due to fewer moving parts.

In the non-modulating exhaust system, the exhaust airflow is constant whenever the ex­haust fan is operating. This type of control should only be used to either assist a smoke

purge system or when a system requires a constant volume of exhaust airflow.

ACOUSTICAL CONSIDERATIONS

The TempMaster OmniElite unit is designed for lower sound levels than competitive units
by using flexible fan connections, fan spring isolators, double-wall construction, multiple
fan options, and lower speed and horsepower fans. For VAV applications, VFDs are used
instead of inlet guide vanes. Additional sound attenuation can be obtained using compres­sor sound blankets when necessary.

Even with these equipment design features, the acoustical characteristics of the entire

installation must never be overlooked. Additional steps for the acoustical characteristics
of a single package unit installation should be addressed during the design phase of a

project to avoid costly alterations after the installation of the equipment. During the design

phase of a project, the designing engineer should consider, at a minimum, the impact of

the equipment location, single package unit installation, building structure, and ductwork.
