Dayton Operating Instructions and Parts Manual <br />Models 4HZ32G thru 4HZ59G, 5DVN6 thru 5DVN9, <br />5DVP0 thru 5DVP9, 5DVR0 thru 5DVR4, <br />6KWH7 thru 6KWH9, 6KWJ0 thru 6KWJ3 <br />Installation (Continued) <br />7. Sealant or caulking should be <br />applied in the groove formed by <br />the mounting plate and the wall <br />to prevent moisture leakage into <br />the building. Run electrical cable <br />from within building, through <br />the damper clearance hole and <br />ventilator conduit chase to the <br />motor compartment. <br />8. Re -attach ventilator to the mounting <br />plate. The unit should be aligned <br />with the breather tube pointing <br />straight down. <br />9. Guide conduit tube through the <br />hole in the motor support pan. <br />Horizontal support channels should <br />slide over the mounting angle clips <br />on the mounting plate until the <br />holes in the windband and clips <br />are aligned. Replace fasteners and <br />tighten. <br />10. Mount and wire safety disconnect <br />switch under ventilator cover and <br />wire motor per connection wiring <br />diagram on motor. Wire control <br />switches at ground level. Refer to <br />Electrical Connection, Figure 7. <br />11. Replace motor cover. <br />UL 762 COMMERCIAL KITCHEN <br />1. Install per NFPA 96 requirements for <br />restaurant exhaust appliarkes. <br />2. Use optional grease collector box, <br />hinge kit, external junction box. <br />A WARNING Do not use a damper <br />any kitchen exhaust <br />application. <br />3. Duct size must be equal to or larger <br />than inlet opening. Some local codes <br />require a continuous weld between <br />duct and inlet. keep motor cooling <br />tube clear. <br />Figure 5 — Kitchen Roof -Mount <br />Figure 6 — Kitchen Wall -Mount <br />ELECTRICAL CONNECTION <br />NOTE: Refer to motor nameplate for <br />wiring procedures. Refer to switch <br />manufacturer for installation and <br />wiring procedures. <br />NOTE: Exhaust fans used in kitchen <br />ventilation applications must have <br />external wiring. <br />NOTE: Motor and disconnect must be <br />classified as hazardous for 6KWJ2 and <br />6KW13 fans to be suitable for use in <br />hazardous environments. Installation <br />must be performed by a qualified <br />personnel with suitable motor and <br />disconnect for application. <br />1. Motor and fan must be securely <br />grounded (bare metal) to a suitable <br />electric ground, such as a grounded <br />water pipe or ground wire system. <br />NOTE: Refer to Figure 7 for connection <br />wiring diagram. <br />Figura 7 — Typical Wiring Diagram <br />Operation <br />1: Before starting up or operating, <br />- check all fasteners for tightness. In <br />particular, check set screws in wheel <br />hub (and sheaves, if applicable). <br />While in the OFF position, or before <br />connecting the ventilator to power, <br />turn the fan wheel by hand to be <br />sure it is not striking the orifice or <br />any obstacle. <br />2. Start the ventilator up and shut it <br />off immediately to check rotation of <br />the wheel with directional arrow in <br />the motor compartment. Ventilator <br />wheel should rotate clockwise <br />when viewed from the top. <br />3. When the ventilator is started, <br />observe the operation and check for <br />any unusual noises. Keep inlets and <br />approaches to ventilator clean and <br />free from obstruction, <br />4. With the system in full operation <br />and all duct work attached, measure <br />current input to the motor and <br />compare with the nameplate <br />rating to determine if the motor <br />is operating under safe load <br />conditions. <br />5. Variable speed models include a <br />motor mounted potentiometer. <br />A dial is mounted on the case of <br />the motor to adjust the speed. To <br />adjust the speed <br />of the motor, use a <br />screwdriver to turn <br />the potentiometer. <br />Figure 8 —Variable speed Adjustment <br />
