Safety

Attention should be paid to the following statements:

NOTE - Notes are intended to clarify the unit installation, operation and maintenance.

CAUTION - Caution statements are given to prevent actions that may result in

equipment damage, property damage, or personal injury.

WARNING - Warning statements are given to prevent actions that could result in

equipment damage, property damage, personal injury or death.

DANGER - Danger statements are given to prevent actions that will result in equipment

damage, property damage, severe personal injury or death.

ELECTRIC SHOCK, FIRE OR EXPLOSION HAZARD

Failure to follow safety warnings exactly could result in dangerous operation, serious injury, death or property damage.

Improper servicing could result in dangerous operation, serious injury, death or property damage.

 Before servicing, disconnect all

electrical power to the unit. More than one disconnect may be provided.

 When servicing controls, label all

wires prior to disconnecting. Reconnect wires correctly.

 Verify proper operation after

servicing. Secure all doors with key-lock or nut and bolt.

Electric shock hazard. Before servicing, disconnect all electrical power to the unit, including remote disconnects, to avoid shock hazard or injury from rotating parts. Follow proper Lockout-Tagout procedures.

FIRE, EXPLOSION OR CARBON MONOXIDE POISONING HAZARD

Failure to replace proper controls could result in fire, explosion or carbon monoxide poisoning. Failure to follow safety warnings exactly could result in serious injury, death or property damage. Do not store or use gasoline or other flammable vapors and liquids in the vicinity of this appliance.

7

VARIABLE FREQUENCY DRIVES

Do not leave VFDs unattended in hand mode or manual bypass. Damage to personnel or equipment can occur if left unattended. When in hand mode or manual bypass mode VFDs will not respond to controls or alarms.

GROUNDING REQUIRED

All field installed wiring must be completed by qualified personnel. Field installed wiring must comply with NEC/CEC, local and state electrical code requirements. Failure to follow code requirements could result in serious injury or death. Provide proper unit ground in accordance with these code requirements.

During installation, testing, servicing and troubleshooting of the equipment it may be necessary to work with live electrical components. Only a qualified licensed electrician or individual properly trained in handling live electrical components shall perform these tasks.

Standard NFPA-70E, an OSHA regulation requiring an Arc Flash Boundary to be field established and marked for identification of where appropriate Personal Protective Equipment (PPE) be worn, should be followed.

UNIT HANDLING

To prevent injury or death lifting equipment capacity shall exceed unit weight by an adequate safety factor. Always test-lift unit not more than 24 inches high to verify proper center of gravity lift point to avoid unit damage, injury or death.

ROTATING COMPONENTS

Unit contains fans with moving parts that can cause serious injury. Do not open door containing fans until the power to the unit has been disconnected and fan wheel has stopped rotating.

Electric motor over-current protection and overload protection may be a function of the Variable Frequency Drive to which the motors are wired. Never defeat the VFD motor overload feature. The overload ampere setting must not exceed 115% of the electric motors FLA rating as shown on the motor nameplate.

Failure to properly drain and vent coils when not in use during freezing temperature may result in coil and equipment damage.

8

Do not clean DX refrigerant coils with hot water or steam. The use of hot water or steam on refrigerant coils will cause high pressure inside the coil tubing and damage to the coil.

WATER PRESSURE

Prior to connection of condensing water supply, verify water pressure is less than maximum pressure shown on unit nameplate. To prevent injury or death due to instantaneous release of high pressure water, relief valves should be field supplied on system water piping.

To prevent damage to the unit, do not use acidic chemical coil cleaners. Do not use alkaline chemical coil cleaners with a pH value greater than

8.5, after mixing, without first using an aluminum corrosion inhibitor in the cleaning solution.

Do not use oxygen, acetylene or air in place of refrigerant and dry nitrogen for leak testing. A violent explosion may result causing injury or death.

Always use a pressure regulator, valves and gauges to control incoming pressures when pressure testing a system. Excessive pressure may cause line ruptures, equipment damage or an explosion which may result in injury or death.

Do not work in a closed area where refrigerant or nitrogen gases may be leaking. A sufficient quantity of vapors may be present and cause injury or death.

Rotation must be checked on all MOTORS AND COMPRESSORS of 3 phase units at startup by a qualified service technician. Scroll compressors are directional and can be damaged if rotated in the wrong direction. Compressor rotation must be checked using suction and discharge gauges. Fan motor rotation should be checked for proper operation. Alterations should only be made at the unit power connection

Do not weld or cut foam panel with plasma cutters or a cutting torch – When burnt the foam produces dangerous fumes.

When steam cleaning coils, be sure areas on both sides of the coil are clear personnel.

9

Some chemical coil cleaning compounds are caustic or toxic. Use these substances only in accordance with the manufacturer’s usage instructions. Failure to follow instructions may result in equipment damage, injury or death.

Door compartments containing hazardous voltage or rotating parts are equipped with door latches to allow locks. Door latch are shipped with nut and bolts requiring tooled access. If you do not replace the shipping hardware with a pad lock always re-install the nut & bolt after closing the door.

Check the shipping section weights on the Bill of Lading to be sure they can be lifted safely. Rigging should be adjusted so that all sections are lifted level.

Do not enter or reach into a fan cabinet while the fan is still turning.

Never attempt to open an access door or remove a panel while the unit is running. Pressure in the unit can cause excessive force against the panel.

Never pressurize equipment over 8”

w.c – Equipment and property damage, personal injury or loss of life could result.

Ensure that sufficient dampers will be open to provide air path before fan is allowed to run.

Risk of injury from hot parts – Disconnect all power, close all isolation valves and allow equipment to cool before servicing equipment with hot water and steam heating coils. Hot water will circulated even after the power is off.

PVC (Polyvinyl Chloride) and CPVC (Chlorinated Polyvinyl Chloride) are vulnerable to attack by certain chemicals. Polyolester (POE) oils used with R-410A and other refrigerants, even in trace amounts, in a PVC or CPVC piping system will result in stress cracking of the piping and fittings and complete piping system failure.

10

HOT PARTS

Disconnect all power, close all isolation valves and allow equipment to cool before servicing equipment to prevent serious injury. Equipment may have multiple power supplies. Electric resistance heating elements and hot water or steam heating coils may have automatic starts. Hot water will circulate even after power is off.

1. Startup and service must be performed

by a Factory Trained Service Technician.

2. The unit is for indoor or outdoor use.

See General Information section and unit specifications for more unit information.

3. Every unit has a unique equipment

nameplate with electrical, operational, and unit clearance specifications. Always refer to the unit nameplate for specific ratings unique to the model you have purchased.

4. READ THE ENTIRE INSTALLATION,

OPERATION AND MAINTENANCE MANUAL. OTHER IMPORTANT SAFETY PRECAUTIONS ARE PROVIDED THROUGHOUT THIS MANUAL.

1. Assure that freight carrier is in

compliance with Bill of Lading instructions.

2. Inspect delivery before signing Bill of

Lading.

If damage is found or items are missing:

1. Note on Bill of Lading immediately.

2. Call carrier immediately to file a freight

claim and to schedule an inspection.

3. Photograph damage if possible.

4. Do not move or discard damaged freight

packaging materials

5. After losses have been acknowledged by

the freight carrier, contact factory for a repair or replacement part quote.

37

If the optional shrink wrap is selected it should be left on units until placed inside the building. Unprotected units could develop corrosion if left exposed to the environment.

6. With permission of freight carrier, order

parts and/or make repairs.

7. Stay in contact with freight carrier to

ensure payment of your claim.

Nameplate should be checked to ensure the correct model sizes and voltages have been received to match the job requirements.

If repairs must be made to damaged goods, then the factory should be notified before any repair action is taken in order to protect the warranty. Certain equipment alteration, repair, and manipulation of equipment

without the manufacturer’s consent may

void the product warranty. Contact the AAON Warranty Department for assistance with handling damaged goods, repairs, and freight claims: (918) 382-6196.

Note: Upon receipt check shipment for items that ship loose such as filters, thermostats and remote sensors. Consult order and shipment documentation to identify potential loose-shipped items. Loose-shipped items may have been placed inside unit cabinet for security. Installers and owners should secure all doors with locks or nuts and bolts to prevent unauthorized access.

Figure 2 - Lockable Handle

38

The warranty card must be completed in full and returned to AAON not more than 3 months after unit is delivered.

Storage

Indoor units are not designed for outdoor use or storage. Equipment should be protected from environmental conditions such as rain, snow, humidity, extreme temperatures and corrosive chemicals.

If installation will not occur immediately following delivery, then store the equipment in a dry protected area away from construction traffic, and in the proper orientation with all internal packaging in place. Secure all loose-shipped items.

Installation

AAON equipment has been designed for quick and easy installation.

Location/Clearances

Unit should be installed on a flat, level and rigid surface which is capable of supporting the weight of the unit, including water in the coils. It is important that the unit be installed level for drain pan and coil drainage.

The unit should be located so that there is sufficient clearance for accessing doors and panels. A minimum clearance of one unit width is recommended on one side for coil removal.

Check the shipping section weights on the Bill of Lading to be sure they can be lifted safely. Rigging should be adjusted so that all sections are lifted level.

Rigging

The unit should be lifted using all marked lifting points. Spreader bars should be used to prevent damage to the unit. They should be at least 12 inches wider than the unit to prevent damage. Be sure that the protruding coil connections are not interfering with the straps.

to prevent excess lateral force on the lifting points.

All shipping covers should be left in place until ductwork is ready to be connected or shipping sections are ready to be joined.

Figure 3 - Unit Lifting Example

Only two lifting points on each side of the unit should be connected to one spreader bar, and the straps, chains or cables connected to a single spreader bar should be the same length. The angle of each strap should be a minimum of 60° from horizontal

Figure 4 - Unit Lifting Side View

Module Location

Module location is identified by a three digit number which is labeled on the access side of the base rail. The last two digits in the location number are an incremental number for the position.

The numbering begins at the return air side of the unit. Module 101 will always be the bottom module at the return air end of the unit.

39

The unit tag number will also be displayed on each module, so that each module can be reattached to the correct unit.

Figure 5 - Module Location Example

Module Assembly

The following tools are suggested for equipment assembly:

• Power drill with 5/16” socket

• Come-along (2)

• ½” wrench and socket

• Crowbar

• Phillips-head screwdriver

40

1. Move the section chosen to be installed first, to the correct position. It is recommended to start with the heaviest section. If that is not possible then the first section may need to be secured to prevent it from moving when additional sections of the unit are installed.

The modules can be moved by rolling them on pipes. The pipes should be spaced a maximum of one foot apart. See the following figure.

41

Figure 6 - Moving Module with Pipes

2. Remove module shipping covers. Check to make sure neoprene gasket is installed on downstream edge of each section. If any neoprene gasket is damaged or missing it should be repaired with 3/8” thick lowdurometer neoprene.

Figure 8 - Module Connection

4. Pull the two sections together using a come-along attached to the lifting points on the base rail.

Figure 7 - Neoprene Gasket

3. Correctly orient the second section and move it close to the first, while aligning the two sections. The split unit lifting lugs should be removed once there is no longer a need to lift the section.

Figure 9 - Module Connection Example

As the sections come together make sure the integrated splice on the unit walls and roof correctly overlap the walls and roof of the adjoining module.

Bolts

Lifting Lug

The following figure displays a top view of the correctly overlapping module sections with integrated splice.

Figure 10 - Top View of Module

Connection

A crow-bar or similar tool can be used through the lifting holes to line up the two sections.

Figure 12 - Aligning the Top of a Unit

5. Secure the two sections together with bolts in the holes surrounding the lifting hole in the base rail.

Be sure to replace the lifting lugs on either side of the two base rails before bolting together.

Figure 11 - Aligning Two Modules

The top of the two sections can be aligned by using a come-along diagonally across the top of the unit.

42

Figure 13 - Lifting Lugs and Bolts

6. Pull the top of the two sections together using a come-along attached to the lug points in the top-corner rail.

Figure 14 - Come-Along Putting Together

43

7. Pull sections together until exterior skins meet.

Figure 15 - Pulling Sections Together

8. After ensuring that the dimensions are correct, fasten sections together with selftapping screws (#10 HEX HEAD) on top angle.

9. Attach integrated splice on walls and roof to adjoining section with self-tapping screws (#10 HEX HEAD)

Figure 17 - Attaching Splice

10. Attach corner rail cover with provided .5” #10 flat head screws.

Figure 16 - Fastening Sections Together

Figure 18 - Attaching Corner Rail Cover

Removing modules that are too small could result in injury and damage to equipment as the module could tip over. All sections should have a minimum length at least equal to the exterior unit height.

Vibration spring isolators MUST BE adjusted from the shipping position prior to unit start up.

11. Attach the base splice on inside of unit using self-tapping screws (#10 HEX HEAD)

Figure 19 - Attaching Base Splice

Splice should have 1/8” thick neoprene

preinstalled on one side.

Module Disassembly

1. Remove base splice from inside of the unit and remove the top corner rail cover (see Assembly Steps 10 and 11).

2. Remove screws from the integrated splice on walls and roof (see Assembly Step 9).

3. Remove 3 end screws from top angle on both sides of the unit (see Assembly Step 8).

4. Remove bolts connecting the two sections at the base rail. If the sections are to be lifted the lifting lugs must be re-attached to each section (see Assembly Steps 3 and 5).

44

5. Pull one section straight back from the other until all parts have cleared the other section.

Note: When re-assembling sections be sure that all gaskets are in place. It is the contractor’s responsibility to seal all fieldsplit sections.

Spring Isolator Adjustment

AAON M3 Series air handling units are equipped with spring isolators in all blower sections for vibration attenuation.

Prior to unit shipment the isolators are set in the lock down position and the blower section deck is resting on a wood base to protect the unit during transit.

Figure 20 - Blower Spring Isolator

Once the unit is set into place it is important that all of the isolators are adjusted out of the shipping position and the shipping material is discarded before the unit is put into operation.

45

Electric shock hazard. Before attempting to perform any installation, service, or maintenance, shut off all electrical power to the unit at the disconnect switches. Unit may have multiple power supplies. Failure to disconnect power could result in dangerous operation, serious injury, death, or property damage.

The isolators can be adjusted by first loosening the locking bolt located on top of the frame. The adjustment bolt located just below the frame is used to set the spring into the operating position. After the isolator is set for operation the locking bolt must be tightened against the frame.

Adjust the isolators so that the blower frame is in contact with the gasket on all four sides of the bulkhead. The blower frame should be parallel with the base of the unit.

Figure 21 - Spring Isolator Adjustment

Blower Wheels

AAON units are equipped with a backward curved blower wheels that is set to deliver

the air volume specified according to unit size and/or job requirements.

Air Adjustment

In the event that reduced air volume is required, an air volume band can be installed within the blower wheel to reduce the amount of air delivery. If the unit is factory equipped with the air band but additional air delivery is needed, the band can be removed from the wheel.

The air band is sized according to the air delivery specifications and can be ordered from the factory for field installation.

The related photos of the wheel are provided for practical guidelines only in order to identify the air band location in the wheel. Actual field installation of the air band into the wheel will require access into and through the blower wheel venturi.

The band is made of aluminum, sized and equipped with easy bend tabs that are to be inserted into pre-punched slots provided on the wheel. Once the band has been inserted into the slots, it MUST BE secured by bending the tabs over from the back side of the wheel and also MUST BE secured from the inside by connecting the ends together with a pop-rivet in the holes provided on the ends of the band. If the band is to be field installed, a hand held pop-rivet tool is recommended for connecting the band ends together. Caution must be taken to assure that the band is tightly installed and no damage, denting, or alteration to the wheel or blades occurs during the installation.

Condensate drains that are not properly trapped could cause drain pans to overflow possibly resulting in water damage to building.

Condensate Drains

The primary condensate drains must be trapped for proper operation. Draw-through cooling coils will have a negative static pressure in the drain pan area. This will cause an un-trapped drain to back up due to

46

Figure 22 - Supply Fan Banding

air being pulled up through the condensate drain piping. Blow-through coils will have a positive static pressure in the drain pan. The condensate piping on these drain pans must be trapped to prevent pressure loss through the drain.

Condensate drain trapping and piping should conform to all applicable governing codes.

Note: The drain pan connection is a 1.5” MPT fitting.

Figure 23 - Draw-Through Drain Trap

The X dimension on the draw-through trap should be at least equal to the absolute value of the negative static pressure in the drain pan plus one inch. To calculate the static pressure at the drain pan add the pressure drops of all components upstream of the drain pan, including the cooling coil, and add the return duct static pressure. Include the dirt allowance pressure drop for the filters to account for the worst-case scenario.

The height from top of the bottom bend of the trap to the bottom of the leaving pipe must be at least equal to one half of the X dimension. This ensures that enough water is stored in the trap to prevent losing the drain seal during unit startup

Note: The absolute value of the fan inlet pressure will always be greater than or equal to the absolute value of the static pressure in the drain pan on draw-through units, so the fan inlet pressure is a safe value to use for the drain pan static pressure.

Table 1 - Draw-Through Drain Trap

Dimensions

Draw-Through P-Trap Example

Figure 24 – Draw-Through Drain Pan Connection Locations

The unit shown above is a draw-through unit

with a mixing box, 12” cartridge filters with

2” pleated pre-filters, hot water preheat

coils, chilled water cooling coils, and hot water reheat coils. The static pressure in the drain pan area is found by finding the largest negative static pressure entering the unit, and then subtracting any pressure drops between that point and the drain pan.

48

In the case below the outside air static pressure is -0.75” due to duct loss between the unit and the outside air intake. The return air static pressure is -1.5” due to the building pressure and duct loss between the space and the unit. In this case the -1.5” would be used.

The static pressures of all the components between the return air opening and the drain pan need to be subtracted from the external

49

static pressure at the return air opening. These values are listed on the Unit Rating Sheet which can be obtained from the AAON sales representative.

Figure 25 - Example Draw-Through AAONEcat32 Rating Sheet

The following components should be added:

RA Opening 0.28”

12” Cartridge Filter 0.35” Pleated Cartridge Filter 0.30”

Cooling Coil 0.45” Preheat Coil 0.09” Dirt Allowance 0.35”

These values should be added to the

absolute value of 1.5” to get a total of 3.32”

static pressure. Note that the heating coil which is downstream of the drain pan and the discharge opening static pressures are not used in the calculation.

In this case the ‘X’ dimension of the drawthrough p-trap should be at least 4.32”, which is the absolute value of the calculated static pressure in the drain pan plus one inch. The lower part of the p-trap should be half that value, or 2.16”.

The total height of the p-trap would be 6.48” measured from the bottom of the drain pan connection to the top of the bottom bend, so one diameter of the pipe needs to be added to find the required clearance for the drain.

If the outside diameter of the pipe is 1.5” the

total clearance required would be 7.98”. If

the unit has a 6” base rail, accommodations must be made for an additional 2” of drain

pipe to extend below the base rail.

Blow-Through Coils

Figure 26 - Blow-Through Drain Trap

The Y dimension of blow-through traps should be at least equal to the value of the positive pressure in the drain pan plus one inch. This ensures that there will be enough water stored in the trap to counter the static pressure in the drain pan. To find the pressure subtract any pressure drops between the drain pan and the supply blower from the blower discharge pressure. The worst-case scenario for blow-thru coils is the minimum pressure drop, so do not include dirt allowance pressure drops for filters.

The bottom of the leaving pipe should be at least one half inch lower than the bottom of the drain pan connection. This ensures proper drainage when the unit is not running.

Note: It may be necessary to fill the trap manually, or the trap can be filled automatically by operating the unit until enough condensate collects to fill the trap. The trap will then be filled when the unit is turned off.

In this case the supply external static

pressure is 3”. The only components

between the drain pan and the supply-air ductwork are the discharge opening and the heating coil. To find the static pressure in

the drain pan, subtract .08” and .15” from

52

the 3” supply air external static pressure.

This gives a positive pressure in the drain pan of 2.77”. These values are listed on the Unit Rating Sheet which can be obtained from the AAON sales representative.

53

Figure 28 - Example Blow-Through AAONEcat32 Rating Sheet

All drains must be trapped individually before they are connected to a common line.

All condensate drain connections must be used. Drain pans are sloped toward connections.

The ‘Y’ dimension on the blow-through ptrap should be at least 3.77”, or one inch plus the calculated static pressure in the drain pan. The total p-trap height will need

to be 3.77” plus at least .5” and then one

pipe diameter. If the outside diameter of the p-trap pipe is 1.5” then the total height of the trap would be 5.77”. A unit with the 6” base rail would have sufficient height to properly trap this example unit without additional accommodations.

Base Drains

Base drains must be either capped or trapped using the same methods as condensate drains. If a base drain is to be trapped and then piped, the trap must be manually filled before unit operation and periodically afterwards as the water evaporates.

External Control Panel Note: The external control panel is heavy.

Installation is a multi-person job.

The optional external control panel may be shipped loose from the factory. If it is shipped loose, it is secured for shipping in the supply fan module.

To install the external control panel use the following procedure:

1. Remove the external control panel from the shipping position in the supply fan module.

2. Install the external control panel by placing it on the preinstalled mounting bracket on the exterior of the supply fan module.

3. While one or two people hold the external control panel in place on top of the mounting bracket, another person should secure it to the wall of the unit with selftapping #10 screws through the side angles and top angles.

4. Push conduit and wiring from inside the blower cabinet into the external control panel and connect wiring according to the provided wiring diagram.

5. Seal the hole in the foam wall by caulking around the entire perimeter of the conduit on both the inside and the outside of the unit. Use an industrial grade silicone sealant or a duct seal compound.

6. For outdoor units, the top and sides of the external control panel assembly must be sealed against the side of the unit. Apply silicone or polyurethane caulking to the seam along the top and both sides.

Anytime a foam insulated part has a hole or cutout in it, the exposed foam must be sealed from the air stream.

All high voltage electrical connections should be checked for tightness prior to unit startup. Loose connections can cause overheating and component failure.

The foam insulation releases dangerous fumes when it is burnt. Do not cut a foam part with a cutting torch or plasma cutter. Do not weld to a foam filled part.

Figure 29 - External Control Panel

Electrical

All external wiring must comply with the National Electric Code (NEC) and any additional local codes. It is the responsibility of the installer to conform to all necessary codes. All internal wiring complies with UL 1995

Note: All voltages should be within 10% of unit and component nameplate voltages.

Check the unit data plate to make sure it agrees with the power supply. For units that contain factory wiring, connect power supply to the unit according to the provided wiring diagram.

All wiring should be done in conduit on the exterior of the unit. Control wiring should

not be run in the same conduit as power wiring. Protect the branch circuit in accordance with code requirements.

The unit must be electrically grounded in accordance with the National Electric Code, ANSI / NFPA No. 70. In Canada use current C.S.A. Standard C22.1, Canadian Electric Code Part 1.

For field wired units, refer to the motor connection diagram on the inside of the motor terminal box for wiring instructions. Check the electrical characteristics of the motor to make sure they correspond to the supply voltage and the conductor size used.

Foam Insulated Panel Cutting

Note: The location for field cut electrical entry is marked on the unit. Field cut openings must be a minimum of 6 inches away from all components and wiring to prevent damage due to drilling or cutting.

To pass wires through the wall or roof of the unit, a hole should be cut and conduit passed

Care should be taken to ensure that the dampers do not fail to a position where all are closed while the fan is still running. This can result in damage to the unit.

through it. Use the following procedure to cut a round hole in a foam panel.

1. Locate the placement of the hole. Be sure that the conduit will not interfere with the operation of any component or prevent access of any door or removable panel.

2. Drill a pilot hole all the way through the foam wall or roof.

3. Using a hole saw cut the hole through the metal on both sides of the foam part.

4. With a knife cut the foam out of the hole.

5. After the conduit or pipe is installed in the hole caulk the entire perimeter of the hole on both sides with an industrial grade silicone sealant or a duct seal compound.

If a larger cut-out is needed for additional duct connections not provided by the factory, or for any other reason, it is very important that the foam be completely sealed. Insulation covers should be fabricated from sheet metal to cover the foam at the cut. The edges and corners that are not covered should then be sealed using silicone caulking or a duct seal compound.

If a reciprocating saw is used to make the cut-out take care that the metal skins of the foam part do not separate from the foam, this would result in reduced structural integrity of the part.

Dampers and Actuators

56

AAON damper blades are connected with interlocking gears. A coupling is attached to one of the gears for connection to the actuator.

Factory provided actuators have a spring return. The recommended configuration is that the return air actuator should return to an open position and the exhaust and outside air should return to a closed position.

It is recommended that field provided actuators also be spring return with the same configuration listed above.

The factory provided actuators use a 24V power supply and are either on/off or modulating using a 2-10 VDC signal.

Figure 30 - Dampers

57

PVC (Polyvinyl Chloride) and CPVC (Chlorinated Polyvinyl Chloride) are vulnerable to attack by certain chemicals. Polyolester (POE) oils used with R-410A and other refrigerants, even in trace amounts, in a PVC or CPVC piping system will result in stress cracking of the piping and fittings and complete piping system failure.

All piping design and installation should be performed by qualified professionals. All applicable codes and industry standards should be adhered to.

Figure 31 - Dampers and Actuator

Note: If one damper bank is to be

independently controlled by two actuators, the two gears that join the separate portions will need to be cut so that they do not engage each other.

Figure 32 - Independently Controlled

Dampers

Duct System

Remove duct shipping covers immediately prior to duct connection. A 1 inch tall duct flange is provided around each duct opening.

Piping

The coil connections are copper MPT. Use dielectric unions as necessary to prevent galvanic-corrosion.

Always use a backup pipe wrench to prevent excess stress and damage to coil connections. The connecting piping should never be supported by the coil, it should be independently supported. Swing joints or flexible fittings should be used to absorb expansion and contraction due to temperature changes.

An access cover is provided for the chilled water, hot water, and steam coil vent and

Improper installation, adjustment, alteration, service or maintenance can cause property damage, personal injury or loss of life. Startup and service must be done by a Factory Trained Service Technician. A copy of this IOM should be kept with the unit.

Equipment operation during construction will void all manufacturer’s warranties.

drains. Remove the two bolts by each coil connection. When replacing the cover, take care not to over-tighten the bolts as this could cause the rivet-nut to come loose. Vents and drains are sealed with half inch plugs.

All coils should be piped in a counter-flow arrangement. The water entering connection should be on the air leaving side of the coil.

Figure 33 - Hydronic Coil Connections

58

Operation

Before starting up the equipment, building construction should be complete. Startup personnel should:

• Have a working knowledge of general HVAC and mechanical commissioning procedures and practices.

• Be familiar with unit functions, features, optional unit accessories, and all control sequences.

• Have appropriate literature on hand for consultation.

Startup Checklist

• Check all electrical connections for tightness.

• Inspect all sections. Remove any shipping restraints and check for loose debris.

• Check fan set screws for tightness, turn fan to assure free rotation.

• Ensure electrical supply matches unit nameplate.

• Ensure condensate lines are connected, glued, and sloped towards building drain.

• Manually fill any trapped drains. (Condensate drains will fill automatically)

59

Improper startup procedures could damage unit and possibly void manufacturer’s warranties.

Startup check list must be completed before turning unit power on.

• Check for compliance of all codes and special provisions.

• Attach all access panels, close all doors.

• Ensure that ductwork dampers are open.

Procedures

Install any gauges, voltmeter, and ammeter before startup. If any excess sound or vibration occurs during startup, note and determine the cause, and shut off unit immediately to correct.

1. Turn the unit power on.

2. One at a time turn on all blowers, check for correct rotation. Units with factory wiring have been tested. If motor rotation is not correct, switch position of two legs of power at the power entry. Rotation may need to be corrected for each motor for field wired units. Plenum fans should rotate clockwise as viewed from the air leaving side of the motor.

3. When rotation directions are correct, take blower amp readings and check to make sure they are within the safety factor of the motor.

Figure 34 - Blower Rotation

4. With the blowers off, check the operation of all dampers. Ensure that the dampers are operating such that airflow through the unit will not be shut off while the fan is operating. This could cause severe damage to the unit.

5. Check the operation of all water valves. Simulate calls for cooling and heating, check for the proper response of the valves.

Check the operation of any other optional

equipment per the manufacturer’s

specifications.

Commissioning

The commissioning of an air conditioning system is the process of achieving, verifying, and documenting the performance of that system to meet the operational needs of the building. Adjustments made during the commissioning phase may include air or water balancing, or configuration of controls and operational sequences.

Air Balancing

High performance systems commonly have complex air distribution and fan systems. Unqualified personnel should not attempt to adjust fan operation or air circulation, as all systems have unique operating characteristics. Professional air balance

specialists should be employed to establish actual operating conditions and to configure the air delivery system for optimal performance.

Water Balancing

A hydronic specialist with a complete working knowledge of water systems, controls, and operation must be employed to properly balance the entire system. Unqualified personnel should not attempt to manipulate temperatures, pressures, or flow rates, as all systems have unique operating characteristics and improper balancing can result in undesirable noises and operation.

Controls

M3 Series air handlers can be shipped from the factory with no controls and no wiring, wired to terminal blocks, or with a factory installed WattMaster VCM-X controller. If the unit includes a VCM-X controller, the technical guide will be included with the literature package.

Operate unit according to control

manufacturer’s instructions. Contact sales

representative or controls contractor for information on non-factory controls.

Maintenance

Routine Maintenance

Routine maintenance is required to keep the unit running efficiently and minimize down time. The following maintenance schedule should be used.

One week after start-up:

• Check filters for cleanliness. Replace if necessary.

• Check cycling of fans and valves. Correct unusual cycling.

• Check for correct damper operation.

• Check blower set screws. Tighten if

necessary.

Monthly:

• Check filters for cleanliness. Replace if necessary.

• Check drain pans to ensure proper drainage and clean as necessary.

• Inspect all coils. Clean if dirty or obstructed in any way.

Seasonal:

• Check operation of heating and cooling sequences.

• Check for correct damper operation.

• Check fans for wear. Clean if necessary.

Refer to motor manufacturer IOM for relubrication schedule.

• Winterize coils if necessary.

• Inspect and if necessary clean unit interior.

Yearly:

• Clean coils, drain pan and drain line.

• Check electrical connections for tightness.

• Check piping and valves for correct

operation.

Blower Assembly

The M3 Series air handling unit uses only direct drive fans. The only bearings that will need to be lubricated are the ones contained in the motor. Refer to the motor manufacturer maintenance manual for the correct re-lubrication schedule and lubricant information.

It is important that fans be kept clean to maintain efficiency and reduce stress on the unit. To clean the fans first make sure the power to the unit is turned off. Secure the fan so it cannot free-wheel. Clean dust and debris on the fan. Check set screws for tightness. Rotate the fan by hand and check for noise and roughness. The fan should rotate smoothly.

Coils/Drain Pans

Coils must be kept clean to maintain peak unit efficiency and capacity. Clean filters

When steam cleaning coils, be sure area on both sides of coil is clear of excess personnel.

Take care that the coil is not dropped or knocked over. This could damage the coil fins, or cause a leak in the coil.

will help prevent dirty coils; however, coils should still be cleaned at least annually by an HVAC professional.

The coils should be cleaned using steam, low-pressure water, low-pressure air, or a non-corrosive coil cleaner.

Take care not to damage fins while cleaning. High pressure water can damage fins.

Condensate drain pans should be inspected often and cleaned at least annually to maintain proper drainage and prevent the spread of disease. Cooling coils are raised off the drain pan to facilitate cleaning.

The drain and p-traps should also be checked to prevent clogging. A clogged drain will result in water backing up in the drain pan and potentially damaging the unit and the building.

Winterizing Coils

In some cases it may be necessary to winterize water coils to prevent them from freezing.

First completely drain the coils. There is a

drain located below the ‘water in’

connection and a vent connection located above the ‘water out’ connection. Auxiliary drain piping can also be added to exterior water piping if yearly winterizing is necessary. After the coil is drained, fill with an antifreeze solution using a circulating pump. Then thoroughly drain.

Removing Coils

Coils on the M3 units can be removed from either side of the unit. The coils are independently supported so they can be removed independently from either side of the unit.

To remove a coil, first disconnect the water piping from the coil. Remove the coil access panel on the side from which the coil is to be removed. Remove the screws connecting coil end panel to the coil. Slide the coil straight out onto a support that is at the same level as the coil.

To replace the coil, the above procedure should be reversed. The coil should first be placed on a support that is at the same level as the coil position in the unit. The coil should then be slid straight into the unit.

The upper coil location has angles on both the front and back side of the coil; the lower coil has an angle on the downstream side of the coil and guides on the upstream side. Be sure that the coil is all the way up against the front (downstream) side of the coil, this should center the coil in the opening.

Push the coil all the way in so that the return-bend side of the coil is between 1/8” and 1/4” from the inside wall of the unit. For cooling coils, be sure that the vertical headers are entirely over the drain pan. Screw the coil end panel to the coil using self-tapping sheet metal screws.

Shut off power to unit and wait for fans to stop turning before removing an access panel. To make sure the unit is not pressurized, open door opposite the access panel. Serious injury can result from removing a panel under positive pressure.

To remove an access panel, remove bolts from the perimeter. When replacing a panel, make sure that the neoprene gasket on the panel is not damaged. Do not over-tighten the bolts as this could cause the rivet-nuts to come loose.

Figure 35 - Coil Removal

Doors/Panels

Removable access panels are provided directly across from most access doors. If regular access is required from the panel side of the unit, the doors and panels can be swapped or additional doors can be ordered from the factory. Contact sales representative to order additional parts.

Note: For safety, inside-opening doors are used in positive pressure sections and outside-opening doors are used in negative pressure sections. The opening direction of doors cannot be changed.

62

Figure 36 - Access Door/Panel Removal

Outside Opening Door and Panel

To switch the door and access panel locations remove panel and remove door by removing the screws connecting the hinge to the unit. For inside opening doors, the gap covers around the door opening should also be removed.

63

Figure 37 - Access Door

Install the door on the opposite side of the unit by attaching the hinge to the unit. Be sure that the door is centered in the opening. Rubber gasket needs to be applied on the door jamb of the new door side. The door latch parts will need to be removed and replaced on the new door side.

Filters

Pleated filters install from upstream side of filter rack. Filters are installed in columns. For each column open snap-fasteners and remove first filter. Slide the rest of the filters to the opening and then remove.

Bag and cartridge filters are installed with a type 8 holding frame. Use the provided clips to attach new filters. Be sure to remove prefilter clips from cartridge filters before discarding. Pre-filter clips will need to be attached to replacement cartridge filters.
