Unit Features & Benefits—MPS-007A thru 020A
Maverick I rooftop units are designed from the ground up with the latest features and benefits required to compete in today’s market. The clean design stands alone in the industry and is a testament to the quality, reliability, ease of installation and serviceability that goes into each unit.
The sheet-metal cabinet ( 2 ) uses nothing less than 18-gauge material for structural components with an underlying coat of G90. To ensure the leak-proof integrity of these units, the design utilizes a one-piece top with a 1/8" drip lip ( 3 ), gasket-protected panels and screws. The Maverick I hail guard ( 4 ) sets the standard for coil protection in the industry. Every unit has an electro deposition baked-on powder coat finish and is tested to withstand a rigorous 1000-hour salt spray test, per ASTM B117.
Anything built to last must start with the right foundation. In this case, the foundation is 14-gauge, commercial-grade, full-perimeter base rails ( 5 ), which integrate fork slots and rig-ging holes to save set-up time on the job site. The base pan is stamped, which forms a 1-1/8" flange around the supply and return opening to prevent water entering the conditioned space ( 6 ). The drainpan ( 7 ) a non-corrosive polymer that resists the growth of harmful bacteria and is sloped for the latest IAQ benefits. The insulation has been placed on the underside of the basepa n, removing areas that would allow for potential moisture accumulation, which can facilitate growth of harmful bacteria. All insulation is secured with both adhesive and
mechanical fasteners, and all edges are hidden. Each unit was tested to U.L. 1995, ANSI 21.47 and ARI 340-370. Each unit bears the U.L. and ARI certification labels located on the unit nameplate ( 8 ). Contractors can rest assured that when a Maverick I unit arrives at the job, it is ready to go with a fac-tory charge and quality checks. Each unit also proudly dis-plays the “Made in the USA” designation.
Access to all major compartments is from the front of the unit, including the filter and electrical compartment, blower compartment, furnace section, and outdoor section. Each panel is permanently embossed with the compartment name (control/filter access, blower access and furnace access).
Electrical and filter compartment access is through a large, toolless, hinged-access panel. On the outside of the panel is the unit nameplate, which contains the model and serial num-ber, electrical data and other important unit information.
The unit charging chart is located on the inside of the electri-cal and filter compartment door. Electrical wiring diagrams are found on the control box cover, which allows contractors to move them to more readable locations. To the right of the control box the model and serial number can be found. Having this information on the inside will assure model identification for the life of theproduct. The produc-tion line quality test assurance label is also placed in this location( 9 ). The two-inch throwaway filters ( 10 ) are easily removed on a tracked system for easy replacement.

Unit Features & Benefits—MPS-007A thru 020A
Inside the control box ( 11 ), each electrical component is clearly identified with a label that matches the component to the wire diagram for ease of trouble shoot-ing. All wiring is numbered on each end of the termination and color-coded to match the wiring diagram. The integrated furnace control, used to control furnace operation, incorporates a flashing LED trouble-shooting device. Flash codes are clearly outlined on the unit wiring diagram. The con-trol transformer on units 7.5 tons and above has a low voltage cir-cuit breaker that trips if a low voltage electrical short occurs. There is a blower contactor and compressor contactor for each compressor.
For added convenience in the field, a factory-installed conve-nience outlet and disconnect( 12 ) are available. Low and High voltage can enter either from the side or through the base. Low-voltage connections are made through the low-voltage terminal strip. For ease of access, the U.L.-required low voltage barrier can be temporarily removed for low-voltage termination and then rein-stalled. The high-voltage connection is terminated at the num-ber 1 compressor contactor. The suggested mounting for a field-installed disconnect is on the exterior side of the electri-cal control box.
To the right of the electrical and filter compartment are the externally mounted gauge ports, which are permanently iden-
tified by embossed wording that clearly identifies the compressor circuit, high pressure connection and low pressure connection ( 13 ). With the gauge ports mounted externally, an accurate diagnostic of system operation can be per-formed quickly and easily without disrupting airflow.
The blower compartment is to the right of the gauge ports and can be accessed by removing 5/16" washer-head screws. This panel is not hinged to assure a water-tight fit with the unit. To allow easy maintenance of the blower assembly, the entire assembly easily slides out by removing two 3/8" screws from the blower retention bracket. The adjustable motor pulley( 14 ) can easily be adjusted by loosening the bolts on either side of the motor mount. Removing the bolts allows for easy removal of the blower pulley by pushing the blower assembly up to loosen the belt. Once the belt is removed, the motor sheave can be adjusted to the desired number of turns, ranging from 0 to 6 turns open. Where the demands for the job require high static, McQuay has high-static drives available that deliver nominal airflow up to 2" of static. By referring to the airflow performance tables listed in the installation instructions, proper static pressure and CFM requirements can be dialed in. The scroll housing ( 15 ) and blower provide quiet and efficient airflow. The blower sheave

Unit Features & Benefits—MPS-007A thru 020A
is secured by an “H” bushing which firmly secures the pulley to the blower shaft for years of trouble-free opera-tion. The “H” bushing allows for easy removal of the blower pulley from the shaft, as opposed to the use of a set screw, which can score the shaft, creating burrs thatmake blower-pulley removal difficult.
Also inside the blower com-partment are the optional low-ambient control ( 16 ), low-pressure switch ( 17 ), high-pressure switch ( 18 ) and freeze stat refrigerant safety device ( 19 ). The low-ambient control allows for opera-tion of the compressor down to 0 degrees ambient tempera-ture by cycling the outdoor fans on high pressure. The high-pressure switch will shut off the compressors if pressures exceeds, 450 PSIG are detected, this may occur if the outdoor fan motor fails. The low-pressure switch shuts off the com-pressors if low pressure is detected due to loss of charge. The freeze stat protects the compressor if the evaporator coil gets too cold (below freezing) due to low airflow. Each factory-installed option is brazed into the appropriate high or low side and wired appropriately.
Inside the blower compartment the interlaced evaporator can also be viewed. The evaporator uses enhanced fin tech-nology for maximum heat transfer. The cap-tube metering device assures even distribution of refrigerant throughout the evaporator.
Wiring throughout the unit is neatly bundled and routed. Where wire harnesses go through the condenser bulkhead or blower deck, a molded wire harness assembly ( 20 ) provides an air-tight and water-tight seal, and provides strain relief.
Care is also taken to tuck raw edges of insulation behind sheet metal to improve indoor air quality. The furnace compartment
contains the latest furnace technology on the market. The draft inducers ( 21 ) draw the flame from the in-shot burners( 22 ) into the aluminized tubular heat exchanger ( 23 ) for clean, efficient gas heat. Stainless steel heat exchangers can be factory installed for those applications that have high fresh-air requirements, or applications in corrosive environ-ments. Each furnace on units 7.5 tons and above is equipped with a two-stage gas valve ( 24 ), which provides two stages of gas heat input. The first stage operates at 50% of the second stage (full fire). 81% steady state efficiency is maintained on both first and second stage by staging the multiple inducers to
optimize the combustion airflow and maintain a near stoichio-metric burn at each stage.
The direct spark igniter ( 25 ) assures reliable ignition in the most adverse conditions. This is coupled with remote flame sense ( 26 ) to assure that the flame has carried across the entire length of the burner assembly. Gas supply can be routed from the side or up through the base.
Each furnace has the following safety devices to assure con-sistent and reliable operation after ignition: • Pressures switches ( 27 ) to assure adequate combustion
airflow before ignition. • Rollout switches ( 28 ) to assure no obstruction or cracks in
the heat exchanger.• High limit device that protects the furnace from over-tem-
perature problems.

Unit Features & Benefits—MPS-007A thru 020A
The compressor compartment houses the heartbeat of the unit. The scroll compressor ( 29 ) is known for its long life, and for
reliable, quiet, and efficient operation. The suction and discharge lines are designed with shock loops ( 30 ) to absorb the strain and stress that the starting torque, steady state operation, and shut down cycle impose on the refrigerant tub-ing. Each com-pressor and circuit is inde-pendent for built-in redun-dancy, and each circuit is clearly
marked throughout thesystem. Each unit, 7.5 tons and above, has two stages ofefficient cooling operation, first stage is approximately50% of second stage.
The condenser fan motor ( 31 ) can easily be accessed and maintained through the compressor compartment. The polar-ized plug connection allows the motor to be changed quickly and eliminates the need to snake wires through the unit.
The outdoor coil uses the latest enhanced fin design ( 32 ) for the most effective method of heat transfer. The outdoor coil is protected by optional louvered panels, which allow unob-structed airflow while protecting the unit from both Mother Nature and vandalism.
Each unit is designed for both downflow and horizontal applications ( 33 ) for job configura-tion flexibility. The return air compartment can also contain an economizer ( 34 ). Two economizer models are avail-able, one for downflow appli-cations, and one for horizon-tal applications. Each unit is pre-wired for the economizer to allow quick plug-in instal-lation. The economizer is also available as a factory-installed option. The economizer, which provides free cooling when outdoor condi-tions are suitable and
also provides fresh air to meet local requirements, comes standard with single enthalpy controls. The controls can be upgraded to dual enthalpy easily in the field. The direct drive actuator combined with gear drive dampers has eliminated the need for linkage adjustment in the field. The economizer control has a minimum position setpoint, an outdoor-air set-point, a mix-air setpoint, and a CO2 setpoint. Barometric relief is standard on all economizers. The power exhaust is housed in the barometric relief opening and is easily slipped in with a plug-in assembly. Power Exhaust is easily field-installed ( 36 ).
The McQuay roofcurb ( 35 ) is made for toolless assembly at the jobsite by hinge pin connec-tion on the adjacent curb sides which makes the assembly process quickand easy.

Selection Procedure Example
To select an MPS Cooling and Heating unit to meet a job requirement, follow this procedure, with example, using data supplied in this specification sheet.1. DETERMINE COOLING AND HEATING REQUIREMENTS
AND SPECIFIC OPERATING CONDITIONS FROM PLANS AND SPECS.Example: Total cooling capacity—106,000 BTUH [31.26 kW]Sensible cooling capacity—82,000 BTUH [24.03 kW]Heating capacity—150,000 BTUH [43.96 kW]*Condenser Entering Air—95°F [35°C] DB*Evaporator Mixed Air Entering— 65°F [18°C] WB; 78°F [26°C] DB*Indoor Air Flow (vertical)—3600 CFM [1699 L/s]*External Static Pressure—.40 in. WG
2. SELECT UNIT TO MEET COOLING REQUIREMENTS.Since total cooling is within the range of a nominal 10 ton [35.2 kW] unit, enter cooling performance table at 95°F [35°C] DB condenser inlet air. Interpolate between 63°F [2°C] and 67°F [19°C] to determine total and sensible capacity and power input for 65°F [18°C] WB evap inlet air at 4000 CFM [1888 L/s] indoor air flow (table basis):Total Capacity = 119,500 BTUH [35.02 kW]Sensible Capacity = 101,200 BTUH [29.66 kW]Power Input (Compressor and Cond. Fans) = 11,650 wattsUse formula [1.10 x CFM x (1 – DR) x (dbE – 80)] in note to determine sensible capacity at 80°F [26.7°C] DB evap- o-rator entering air:Sensible Capacity = 94,230 BTUH [27.62 kW]
3. CORRECT CAPACITIES OF STEP 2 FORACTUAL AIR FLOW.Select factors from airflow correction table at 3600 CFM [1699 L/s] and apply to data obtained in step 2 to obtain gross capacity:Total Capacity, 119,500 x .98 = 117,110 BTUH [34.32 kW]Sensible Capacity, 94,230 x .95 = 89,519 BTUH [26.24 kW]Power Input 11,650 x .99 = 11,534 WattsThese are Gross Capacities, not corrected for blower motor heat or power.
4. DETERMINE BLOWER SPEED AND WATTS TO MEET SYSTEM DESIGN.Enter Indoor Blower performance table at 3600 CFM [1699 L/s]. Total ESP (external static pressure) per the spec of .40 in. includes the system duct and grilles. Add from the table “Component Air Resistance,” .076 for wet coil, .13 for vertical air flow, for a total selection static pressure of .606 (.6) inches of water, and determine:
RPM = 796WATTS = 1,650DRIVE = L (standard 2 H.P. motor)
5. CALCULATE INDOOR BLOWER BTUH HEAT EFFECT FROM MOTOR WATTS, STEP 4.
BTUH = 1,650 x 3.412 = 5,630
6. CALCULATE NET COOLING CAPACITIES, EQUAL TO GROSS CAPACITY, STEP 3, MINUS INDOOR BLOWER MOTOR HEAT.
Net Total Capacity = 117,110 – 5,630 =111,480 BTUH [32.67 kW]
Net Sensible Capacity = 89,519 – 5,630 =83,889 BTUH [24.59 kW]
7. CALCULATE UNIT INPUT AND JOB EER.Total Power Input = 11,534 (step 3) + 1,650
(step 4) = 13,184 Watts
EER = Net Total BTUH [kW] (step 6) = 111,480 = 8.46 Power Input, Watts (above) 13,184
8. SELECT UNIT HEATING CAPACITY.From Physical Data Table read that gas heating output (input rating x efficiency) is:
Heating Capacity = 182,300 BTUH [53.43 kW]
*NOTE: These operating conditions are typical of a commercial applica-tion in a 95°F/79°F [35°C/26°C] design area with indoor design of 76°F [24°C] DB and 50% RH and 10% ventilation air, with the unit roof mounted and centered on the zone it conditions by ducts.
