INTRODUCTION & INSTALLATION

Storage

• Long-term storage requires special attention. Units should be stored on a level, solid surface, preferably indoors.
• If outside storage is necessary, protect the units against moisture and dirt by encasing the cartons in plastic or some similar weatherproof material.

Unpacking

• Place the carton in an upright position and remove staples or use a sharp (knife edge) tool to CAREFULLY cut or scribe the sealing tape on both sides at the top of the carton.
• Open carton flaps. Remove any cardboard and wooden filler pieces, as well as loose components or accessories shipped with the unit.
• Carefully remove the unit from the carton. Inspect the unit for any damage that may have occurred during transit and check for loose, missing, or damaged parts.

Installation

• CAUTION For general ventilating use only, do not use to exhaust hazardous or explosive materials and vapors.
• Remove internal protective shipping trays and fillers. Check for and remove any loose hardware or particles from the inside of the fan housing. Disconnect the motor cord and plug from the internal terminal box and receptacle.
• On installations made before a final ceiling is installed, with access from below, the following procedure applies.
• Assemble adjustable flanges to fan housing with four self-tapping metal screws provided. The adjustable flanges should be located as illustrated in Figure 1.
• PennBarry Ceiling Fans are quiet. They are designed for applications where a low-noise, high-reliability ceiling or cabinet fan is required.
• With air capacities from 30 to 1600 CFM, they’re ideally suited for use in ventilating bathrooms or other low to medium-CFM applications.
• Housings are fabricated of sturdy galvanized steel to ensure durability. Acoustic insulation, in combination with matched motor and wheel assemblies, lowers sound levels and improves air performance.
• Further, motors are mounted on vibration isolators to minimize noise levels. Together, these features ensure years of problem-free, quiet operation.

Receiving and Handling

• PennBarry fans are carefully inspected before leaving the factory. When the unit is received, inspect the carton for any signs of tampering. Inspect the unit for any damage that may have occurred during transit and check for loose, missing, or damaged parts.
• Mishandled units can void the warranty provisions. PennBarry is not responsible for damages incurred during shipment.
• Avoid severe jarring and/or dropping. Handle units with care to prevent damage to components or special finishes.
• Note: Standard Zephyrs are set up for RA (right angle discharge). For TD (top discharge) or TDA (Inline), see conversion instructions
• Note: On model Z6S / H, when using a variable speed controller, wire to the high (h) setting only.
• Using appropriate hardware (i.e. wood screws or sheet metal screws, depending on joist construction), secure the adjustable flanges to each joist. Attach a properly sized duct-to-duct sleeve mounted on the fan housing.
• Run this duct system to an appropriate wall or roof cap. The discharge side must be guarded unless it is connected to the duct.
• Normally, power is brought up from within the building through conduit lines and located at the terminal box. Before wiring is attempted, always lock out the primary and secondary power source. Utilizing the pre-punched hole found at the terminal box on the fan housing, insert a 3/8” electrical connector. All wiring furnished should be in strict accordance with the National Electrical Code and local, state, and federal standards. Complete the installation by cutting a 9 1/2” by 12 1/2” ceiling opening for the Z3, Z5 and Z6; 11 7/8” by 13 3/4” for the Z8 and Z81; 14 1/2” by 18” for the Z10; and 14 1/2” by 23 3/4” for Z101, Z102, Z12 and Z121 ceiling fan.
• Installation of ceiling fans in suspended ceiling systems requires a minimum of 10 gauge solid wire for hanging or suspending the ceiling fan. Four wires per unit should be connected to the pre-punched holes of the adjustable mounting flanges (after the flanges have been mounted to the fan housing as outlined above).
• Note: For the Z12 and Z121, 1/4” threaded rods or perforated steel strips should be used per fan as illustrated in Figure 4.
• If installation is to be made with the ceiling in place, access must be from above. The following procedure should be used for installing the Zephyr ceiling fans. Assemble the adjustable flanges to the fan housing as illustrated in Figures 2 or 2A. Position adjustable flanges so the unit is flush with the top side of the ceiling surface. Tighten the adjustable flanges and secure them with the appropriate hardware (wood screws or sheet metal screws, depending on framing construction). Use the housing as a template, punch or drill a small hole through the ceiling at each corner of the housing, and cut an opening in the ceiling, using these holes as a guide. Install the duct and electrical service under the instructions listed in the previous section.
• In installations where the ceiling is already installed and there is no access from above, the following procedure should be followed. Before cutting the ceiling opening, determine the exact location of framing or support members. Cut holes in the ceiling using care not to exceed the dimensions of the ceiling grille. Note: The ceiling hole should be cut so that one edge of the hole is in line with the inside face of the joist. The hole must be large enough to permit passage of the fan housing into the ceiling space. Care should be taken not to exceed the ceiling grill dimensions when cutting.
• Remove the blower assembly from the housing. For single blower units, remove two #10 sheet metal screws near the blower; slide the power pack to the left to release it from the housing. (For double blower units, remove one 1/4” bolt).
• Electrical service should now be brought up to the fan location. This should be done under the instructions listed in the previous section.
• To secure housing in ceiling space, raise the housing into place with one edge of the housing against joist “A” (see Figure 3). Determine if it is necessary to build out from joist “B” so that the housing can be secured from both sides. If building out is necessary, an appropriate piece(s) of wood should be utilized. These wood spacers should be nailed to joist “B” to increase the thickness of the joist at the point where the fan will be installed. The fan housing should fit snugly between joist “A” and joist “B” (or the built-out section of joist “B”). If spacers are required for joist “B”, they should be sized according to the dimension of the fan housing. Using care to avoid damage to the housing, secure the housing to the joists by nailing through the pre-punched holes found at the top and bottom of the housing sides.
• These pre-punched holes would normally be utilized as a point of attachment for the adjustable flanges; however, these flanges will not be necessary with this type of installation.
• Before the nails are driven snug, care should be taken to ensure that the housing is 1/4” above the ceiling level. Nails should now be secured. Care should be taken to ensure that the nail head is large enough to prevent slipping through the pre-punched holes.
• A washer can be used to increase the bearing surface. Re-attach the blower assembly to the housing. Lock out primary and secondary power sources and secure electrical lines to the terminal box. This should be done under the procedure outlined
• For all of the installation situations described above, the egg crate ceiling grill should be installed as a final step. This is done by first assembling the two torsion springs to the grill. Use the torsion springs and grill buttons from the hardware kit provided.
• Insert the grille buttons into the ceiling grill as shown in Figure 5a through the slot in the grill buttons. The grill is now ready for assembly to the housing. Lift the grill into position below the housing.
• Insert the two torsion springs into the keyhole slots located in the center of the housing as shown in Figure 5B. Push the grill towards the housing

Electrical Connections

Before attempting any repair or installation work, be certain that all power to the motor and electrical accessories is turned off and locked in the off position.

1. Connect motor per nameplate to correct power supply.
2. Install all wiring, protection, and grounding under the national electrical code and local requirements.
3. Follow all local electrical and safety codes, as well as the National Electrical Code (NEC) and the Occupational Safety and Health Act (OSHA).
4. To prevent motor failure when a speed controller is used, the unit must be started at high speed before turning to low speed.

• CAUTION For low speed, insulate black lead as shown in Figure 7.
• For high speed, insulate red lead and connect black to black with a wire nut.
• Note: On Model Z6S / H, when using a variable speed control, wire to the high (H) setting only.
• Make all of the necessary connections by using two wire nuts. A separate ground wire must be connected to the grounding screw. Reinstall the cover of the junction box.

Maintenance

• CAUTION To reduce the risk of injury, disconnect from the power supply before servicing.
• The blower wheel, housing, and grille should be cleaned of dust and grease if required. Power should be disconnected before cleaning the internal parts of the ceiling fan.
• Remove the grill. Use a vacuum cleaner with the appropriate attachments and vacuum dust from the grill. Wash the grill with a warm, soapy solution of water. Allow the grill to air dry thoroughly before reinstalling.
• To clean the blower wheel(s) and housing, unplug the blower from the integral terminal box. Remove the blower assembly from the housing. For single blower units, remove two #10 sheet metal screws near the blower discharge and slide to the left.
• For double-blower units, remove one 1/4” bolt next to the motor. Vacuum blower wheel, if necessary, the wheel can be washed. Use extreme caution – do not allow water to enter the motor. Wipe the blower wheel dry with an absorbent cloth. Before replacing the blower/motor assembly, wipe out the interior of the housing. Replace the blower/motor assembly and secure it with self-tapping screws. Plug in blower motor into the terminal box.
• Note: All motors are checked before shipment; however, if motor defects should develop, prompt service can be obtained from the nearest authorized service station of the motor manufacturer while under warranty. Exchange, repair, or replacement will be provided on a no-charge basis if the motor is defective within the warranty period. The PennBarry representative in your area will provide the name and address of an authorized service station if requested. Do not return defective motors to Pennbarry.
• WARNING: The motor guarantee is void unless overload protection is provided in the motor wiring circuit.

Hidden Danger

• In addition to the normal dangers of rotating machinery, fans present an additional hazard in their ability to suck in not only air but loose materials as well. Solid objects can pass through the fan and be discharged by the impeller as potentially dangerous projectiles.
• Intake to duct work should, whenever possible, be screened to prevent the accidental entrance of solid objects. Access doors or grills to a duct system should never be opened with the fan running.
• When a fan is being started for the first time, a complete inspection of the duct work and interior of the fan should be made (with the power locked off) to make certain there is no foreign material that can be sucked into or blown through the ductwork.

Fan Guards

• All fans have moving parts that require guarding in the same way as other moving machinery. In areas that are accessible only to experienced personnel, a standard industrial-type guard may be adequate.
• This type of guard will prevent the entry of thrown or dropped objects with a minimum restriction of airflow.
• Where the fan is accessible to untrained personnel or the general public, maximum safety guards should be used, even at the cost of some loss of performance.
• CAUTION To reduce the risk of injury of a person, install the fan at least 7 feet above the floor if no guard is installed.
• Roof-mounted equipment will require guards when access is possible, for example, by climbing children.
• Centrifugal fans may be connected directly to duct work which will prevent contact with the internal moving parts, but when the inlet or outlet is exposed, a suitable guard should be installed.
• Do not install it in the cooking or shower stall area.
• CAUTION Units are designed to handle clean air only. Avoid installation in corrosive and dusty environments.
• WARNING To reduce the risk of fire, electric shock, or injury to persons, observe the following.
• A. Use this unit only in the manner intended by the manufacturer. If you have questions, contact the manufacturer.
• B. Before servicing or cleaning the unit, switch the power OFF at the service panel and lock the service panel to prevent power from being switched ON accidentally.
• When the service disconnecting means cannot be locked, securely fasten a prominent warning device, such as a tag, to the service panel.
• CAUTION To reduce the risk of fire, electric shock, or injury to persons, observe the following.
• A. Installation work and electrical wiring must be done by a qualified person(s) under all applicable codes and standards, including fire-rated construction.
• B. Sufficient air is needed for proper combustion and exhausting of gases through the flue (chimney) of fuel-burning equipment to prevent back-drafting. Follow the heating equipment manufacturer’s guidelines and safety standards such as those published by the National Fire Protection Association (NFPA), The American Society for Heating, Refrigeration and Air Conditioning Engineers (ASHRAE), and local code authorities.
• C. When cutting or drilling into a wall or ceiling, do not damage electrical wiring and other hidden utilities.
• D. Ducted fans must always be vented to the outdoors.
