INTRODUCTION
This document contains general installation instructions for the 40UV,UH unit ventilators. Refer to the 40UV,UH Unit Ven­tilators with Product Integrated Controls (PIC) Installation, Start-Up and Service instructions manual for specific PIC control instructions. Refer to the unit wiring diagram or to specific manufacturer literature for any other type of factory­mounted controls.
See submittal drawings for unit configurations, dimensions, clearances, and pipe connections. Refer to unit wiring label for all electrical connections; follow NEC (National Electrical Code) and local codes.
PREINSTALLATION
Unpack and Inspect Units —
from all units. Check the shipment against shipping order. If shipment is damaged or incomplete, file claim with transporta­tion company and advise Carrier immediately.
Remove shipping wraps
Protect Units From Damage — To maintain war-
ranty, protect units against adverse weather, theft, vandalism, and debris on jobsite. Do not allow foreign material to fall into drain pan. Prevent dust and debris from being deposited on motor and fan wheels.
If the equipment is stored for any length of time before in­stallation, it should remain in its shipping container in a clean, dry, and climate controlled area.
Prepare Jobsite for Unit Installation — To save
time and to reduce the possibility of costly errors, set up a com­plete sample installation in a typical room at jobsite. Check all critical dimensions such as pipe, wire, and duct connection requirements. Refer to job drawings and product dimension drawings as required. Instruct all trades in their part of the installation.
Identify and Prepare Units
1. Be sure power requirements match available power source. Refer to the unit nameplate and wiring diagram.
2. Remove front (40UV) or bottom (40UH) access panels from the unit. Retain the panels for reinstallation later.
3. Rotate the fan shaft by hand to ensure that fans are unrestricted and can rotate freely. Check for shipping damage and fan obstructions.

INSTALLATION
Units must be installed level and plumb. Failure to do so may result in excessive vibration and/or premature failure.
Placing Vertical Units in Position
1. Select the unit location; ensure that service clearance is provided. Allow enough grille clearance to maintain un-restricted airflow. See submittal drawings and Fig. 1 and 2 for dimensions.
2. Make sure wall behind unit is smooth and plumb; if necessary, install furring strips on walls with irregular surfaces or mullions. Furring strips must be positioned behind mounting holes in unit. Fasteners, furring strips, and other seals (if required) must be field supplied.
3. Remove all wall and floor moldings from behind the unit.
4. Move unit into position. Unit must be snug against wall and furring strips.
5. Adjust unit leveling legs so unit is level. Unit must be level for proper operation and condensate drainage.
6. Using field-supplied fasteners, reach into unit and attach unit to the wall using the back panel.
7. Protect the unit from jobsite debris. Do not allow foreign material to fall into drain pan. Prevent dust and debris from being deposited on motor or fan.

Make Piping Connections — Access to piping is
available through the access panels at the front, top, or end of the vertical unit (horizontal access from bottom or side). Route piping through the pipe tunnel or the unit’s back panel or floor panel. Metal blank-off panels must be trimmed to complete piping installation. All piping connections must be performed by qualified personnel in accordance with local and national codes.
DRAIN CONNECTIONS — Condensate drain connections are located on each end of the drain pan near the bottom of the unit. Condensate drain line must be galvanized pipe, PVC or similar plastic pipe. Install drain line in accordance with all applicable codes. Insulate the drain line to prevent sweating. See Fig. 6 for typical drain trap construction.
Units with cooling coils require traps to prevent air from entering the condensate fitting and preventing proper drainage. Drain must flow downhill from the unit a minimum of per ft. Drain must be free and clear at all times.

SUCTION LINE
Insulate drain lines to prevent condensate. Care must be taken to avoid interference with control panel on left side drain.
WATER SUPPLY/RETURN CONNECTIONS — Install pip­ing in accordance with all applicable codes. All piping must be supported separately from coils.
Water supply must be connected so that entering water is on leaving-air side of coil. See the connection labels on the unit to locate the inlet. Coils must be adequately vented to prevent air binding. Be sure valves are in proper operating position and are easily accessible for adjustment.
If coil and valve package connections will be made with a solder joint, care should be taken to ensure that components in the valve package are not subjected to high temperatures which may damage seals or other materials. Many 2-position electric control valves are provided with a manual operating lever. This lever should be in the OPEN position during all soldering operations.
If coil connection is made with a union, the coil side of the union must be prevented from turning (it must be backed up) during tightening. Do not overtighten! Overtightening will dis-
tort (egg shape) the union seal surface and destroy the union.
NOTE: A freezestat is factory-installed when a hot water/steam coil is installed.
STEAM CONNECTIONS — On units with steam heating coils, the maximum steam pressure applied to the unit should never exceed 10 psig (operating pressure 6 psig).
DIRECT EXPANSION REFRIGERANT PIPING — Use the condensing unit manufacturer’s recommended line sizes and requirements. Perform leak test using nitrogen. Evacuate and charge per recommended heating, ventilation, and air condi­tioning (HVAC) procedures and all applicable codes. Insulate suction line after leak test up to the coil section end plate for correct operation and to eliminate sweating. Use refrigerant­grade copper lines only. The unit is NOT to be applied as a heat pump.
See Fig. 7 for refrigerant piping connections with recom­mended locations for the thermostatic expansion valve (TXV) and sensing bulb.
HYDRONIC COIL PIPING — When all joints are complete, perform hydrostatic test for leaks. Vent all coils at this time. Check interior unit piping for signs of leakage from shipping damage or mishandling. If leaks are found, notify a Carrier representative before initiating any repairs. Release trapped air from system (refer to Make Final Preparations section).
LIQUID LINE
NOTE: Follow TXV manufacturer’s instructions.
Fig. 7 — Typical TXV (Thermostatic Expansion
Valve) Installation
All water coils must be protected from freezing after initial filling with water. Even if system is drained, unit coils may still have enough remaining water to cause damage when exposed to temperatures below freezing.
Following the hydrostatic test, insulate all piping up to the
coil section end plate to prevent sweating.
To ensure compliance with building codes, restore the struc­ture’s original fire resistance rating by sealing all holes with material carrying the same fire rating as the structure.
Make Electrical Connections — Refer to unit serial
plate for required supply voltage, fan and heater amperage and required circuit ampacities. Refer to unit wiring diagram for unit and field wiring. See Tables 2-4 for electrical data.
All input power wiring connections are accessed through the electrical panel on front right-hand side of the unit. Use the openings that are for the piping connections. See the dimen­sional drawings Fig. 1-5 for electrical box connections.
The fan motor should never be controlled by any wiring or device other than the factory-supplied switch or thermostat/ switch combination unless prior factory authorization is ob­tained. Fan motor may be temporarily wired for use during construction only with prior factory approval and only in strict accordance with the instructions issued at that time.
All electrical connections should be made by qualified per­sonnel and be in accordance with governing codes and ordinanc­es. Any modification of unit wiring without factory authorization will invalidate all factory warranties and nullify any agency list­ings. See Fig. 8A and 8B for typical wiring connections for basic unit without CCN (Carrier Comfort Network®) controls.
Actuators (Field-Supplied) — Field-supplied actuators
must be mounted on1/2in. diameter damper shafts.

Units provided with outside air must utilize the low-
temperature safety switch to prevent coil freeze-up.
Insulate all ductwork as required. Use flexible connections to minimize duct-to-unit alignment problems and noise trans­mission where specified.
Install ductwork, grilles, and plenums so that they do not re­strict access to filter.
Cut openings for supply and return air grilles, thermostats, and switch plates where specified on job drawings. Be careful not to cut wires, piping, or structural supports. Use a steel ther­mostat shield ring to protect drywall from thermostat wiring where applicable.
Prevent dust and debris from settling in unit. If wall finish or color is to be applied by spraying, cover all openings to prevent spray from entering unit.

Make Final Preparations
1. Turn power off (lock out and tag electrical disconnect).
2. Install thermostats and perform any other final wiring as applicable.
3. Clean dirt, dust, and other construction debris from unit interior. Be sure to check fan wheel and housing.
4. Rotate fan wheel by hand to be sure it is free and does not rub on housing.
5. Be sure drain line is clear and is properly and securely positioned. Pour water into drain to check operation.
6. Vent all air from unit coil and related piping. If air vent is manual, release air from system by turning air vent screw
1
/2turns counterclockwise with screwdriver. When
1 steady stream of water begins to escape, close valve. If air vent is automatic, trapped air will be vented automatical­ly. Vent releases air slowly, usually dripping water into drain pan in the process.
Make sure all service valves are open and that motorized control valves, if supplied, are set for automatic operation.
7. Check all control valves in the system for proper opera­tion in accordance with valve manufacturer’s instructions.
8. For units with factory-installed balancing valves, adjust as follows:
a. Butterfly valves — Turn valve gate by inserting
screwdriverintoslotinvalvetopandrotatingupto 90 degrees. Valve is fully open when slot is parallel with valve body. When slot is perpendicular to body, flow through valve is at minimum. Valve does not seal against flow.
b. Ball valves with lever handles — Valve gate action
is similar to butterfly valves above except that when handle is perpendicular to valve body, there is no flow through valve. Ball valves may be used as shutoff valves.
9. Install filter in frame at front of coil. If field-supplied filters are used, be sure size is correct. See Table 1 for filter data.
10. Ensure all panels and filters are installed before checking fan operation. Turn on unit power. Check fan and motor operation.
.
IMPORTANT: Do not start up or operate unit without filter and panels installed. Be sure filter and unit interior are clean.
START-UP
Start-up procedures vary depending on time of year (sum­mer or winter) and building characteristics (new building/old building, occupied/unoccupied, etc.).
Start-up in the Cooling mode requires proper care to avoid condensation problems. Condensation forms on surfaces that are colder than the dew point of the surrounding air. If a unit is started and is piped with low-temperature chilled water in a hot, humid atmosphere, condensation will form on many parts of the unit. In order to avoid excessive condensation, higher temperature water should initially be used (approximately 65 to 70 F). Also, the building should be as completely closed as possible. Close the unit’s outside-air dampers. Bathroom and kitchen exhaust fans should be off.
As the building temperature drops, the chilled water temper­ature can be gradually reduced until it reaches 50 F. At this point the outside-air damper can be opened to take in minimum outside air. When the chilled water temperature is reduced to its design point, the exhaust fans can be turned on.

Page 25
SERVICE
Lock out and tag all power supplies to equipment and con­trols prior to servicing unit. Follow all safety codes. Failure to do so could result in personal injury.
Preventing Excessive Condensation on Unit —
Excessive condensation can be caused by running chilled water through a unit with the unit fan off. If fan cycling is used, a water flow control valve should be installed to shut off the water when the fan stops.
Other methods of control which avoid condensation prob-
lems are as follows:
1. If condensation is forming on the unit, verify the chilled water valve is closing off tightly. Dirt or debris may pre­vent the valve from closing completely.
2. Continuous fan operation with motorized chilled water valve controlled by a thermostat.
3. Continuous fan operation with thermostat control to switchfanfromhightolowspeed(insteadofoff).
Check Drain — Checkdrainpan,drainline,andtrapat
start of each cooling season. A standard type pipe cleaner for
3
/4-in. ID pipe can be used to be sure pipe is clear of obstruction so that condensate is carried away. Check the drain line at filter cleaning time during the cooling season. Be sure that debris has not fallen into unit through supply air grille.
Fan Motor Bearings — Standard motors are perma-
nent split capacitor, which are equipped with permanently sealed and lubricated bearings. No lubrication is required unless special motors have been supplied or unusual operating conditions exist.
Fan Shaft Ball Bearing — The mid and inboard bear-
ings are permanently sealed and lubricated. No additional maintenance is required. The end bearings must be lubricated at the start of each cooling and heating season. Add 5 to 10 drops of SAE 20 or 30 non-detergent based oil to the bearing.
Clean Fan Wheel — For access to fan assembly, remove
discharge grille (if supplied). If unit is connected to ductwork, remove front (40UV) or bottom (40UH) panel, separate fan shaft from motor at bushing, remove motor, and slide fan assembly from track. Use a stiff brush or vacuum to remove dirt and debris from scroll. Wipe all fan surfaces with a damp cloth. Reassemble as necessary.
Clean or Replace Air Filters — At the start of each
cooling season and after each month of operation (more or less depending on operating conditions), replace throwaway filter or clean permanent filter.
THROWAWAY FILTER — Replace filter with a good quality filter of the correct size. Do not attempt to clean and reuse disposable filters. See Table 1 for filter sizes.
PERMANENT FILTER (FIBER TYPE)
1. Tap on solid surface to dislodge heavy particles.
2. Wash in hot water. If needed, use mild solution of com­mercial solvent such as sal soda or trisodium phosphate.
3. Set filter on end so that water drains out through slots in frame. Allow filter to dry thoroughly.
4. Recharge filter with recharging oil. Three ounces is suffi­cient for a medium size filter. Oil may be applied by insect spray gun. For easier spraying, the oil can be warmed.
If the filter is dipped in the recharging oil, remove it immediately and allow to drain through slots in frame.
5. Replace filter in unit. If another type of filter is used, follow the filter manufactur-
er’s instructions.
ECM Motor Removal and Reinstallation (Fig.9)—
commutated motor (ECM) to drive the indoor fan.
The ECM is a factory programmed motor that is standard
with factory-supplied controls (CCN) and units without factory-supplied controls that are used in high-static applica­tions or high-capacity coils.
The ECM is programmed with an algorithm that maintains
a constant torque, as the static pressure on the system varies. For example, as the filter pressure drop increases due to dirt, the fan will increase speed (rpm) to maintain the cfm.
The ECM is identified by the two electrical receptacles
located on the housing. See Fig. 8A, 8B and 9.
The first receptacle is a 5-row in-line connector that feeds
the motor line voltage. This may be either 115 volts or 230 volts. Units that are wired for 230 volts have a jumper be­tween terminals 1 and 2 on this plug (see wiring diagram).
The second receptacle on the motor is a 16-pin connector
and is used for speed switching. This is a low voltage (24-volt) connection. There is a jumper wire between terminals 1 and 3. This is a 24-volt ground. Voltage is present at all times when the motor is energized.
NOTE: A time delay exists between the time the motor speed is switched and the motor’s reaction. This is designed into the electronics and does not indicate motor problems.
When replacing the motor, note the following:
• Check the part number of the old motor against that of the replacement. There is a tag indicating the eight-digit part number and begins with UVE. This is the program number used for this motor.
• The motor must be installed per the instructions below. It is important to maintain the dimension between the fan compartment bulkhead and the coupling.
IMPORTANT: If a replacement cooling shroud has been supplied, it should be installed and the old one discarded. The motor shroud directs cooling air across the motor to provide proper cooling. Never run the motor without the cooling shroud in place. Ensure the shroud inlet ring does not touch the motor; a gap of
1
/16in. to1/8in. is acceptable.
Ensure the unit is completely assembled when checking the fan speed. Replace all panels, including the filters, before checking the fan for operation. When the internal pressure drops at a normal condition, the loading on the motor will be such that the fan can come up to selected speed.
Failure to ensure unit is completely assembled may
result in reduced life of unit and/or personal injury.
To remove and re-install the motors, proceed as follows;
refer Fig. 9:
1. Remove the wire plugs from the motor.
2. Remove the 2 screws holding the motor shroud to the bulkhead.
3. Slide the shroud off the motor to the right.
4. Loosen the 3 setscrews on the shaft coupling between the motor shaft and the fan shaft.

5. Loosen the motor ‘belly band’ and slide motor out of the ‘belly band’ to the right. It is unnecessary to remove the motor mounting bracket from the bulkhead. Loosen only the ‘belly band’ securing the motor in the mount.
6. Reinstall the motor in the ‘belly band.’
7. Ensure the blower wheels are centered within the fan housings (between the inlet rings) before securing the motor shaft coupling.
The motor electronics will fail prematurely if no air is able to circulate over the motor.
8. Ensure the motor housing is at least 1 in. from the bulkhead so that air will be able to circulate over the motor.
9. For vertical type units, position the motor so that the motor wire plugs are front facing on a horizontal plane. For horizontal type units with ceiling mounts, position the motor so that the motor wire plugs are front facing on a vertical plane.
10. Secure the 3 setscrews on the shaft coupling when the motor is properly positioned and the blower wheels are centered within their housing.
11. Re-secure the motor ‘belly band’ around the motor.
12. Reinstall the motor shroud. It is important that the motor shroud be installed prior to operation of the motor. Ensure the venturi is installed on the motor shroud.
13. Re-secure the two screws holding the motor shroud to the bulkhead.
14. Reinstall the motor wire plugs.
