Duct Connections All air ducts should be installed in accordance with the standards of the National Fire Protection Association for the installation of Air Conditioning and Ventilating System other than Residence Type (NFPA 90A), and
Ducts should be designed as a function of the fan orientation. Duct turns and transitions must be made carefully to minimize air friction losses. Avoid sharp turns and use splitters or turning vanes when elbows are necessary. Make turns in the same direction of rotation as the fan. Discharge ductwork should run in a straight line, unchanged in size or direction, for at least a distance of 1-1/ 2-fan diameters (see Appendix C for fan diameter). Refer to Figure 9 and Figure 10 for typical ductwork installation.

Piping Condensate Drain Connection On cooling coil section(s) the drain pan should always be connected directly to a trap to ensure proper drainage of condensate. Caution: Failure to provide adequate condensate piping may result in water damage to the equipment or building. lmportant: The applicable "rule of thumb" for amount of condensate may as high as 6 lbs/hr/ton for units serving
areas with high latent heat. Male-threaded, BSPT 1 1/2" condensate drain connection is provided on one side of the coil section. The main drain lines and trap must be the same size as the drain connection. Pitch the connection line horizontal or downward toward an open drain and install a plugged tee to facilitate cleaning. Condensate lines should not be connected to a closed drain. This is to avoid the possibility of drawing sewer gasses into the unit.
Figure 11 Drain Trap for Draw-Thru Units
Drain traps must be primed. lf they are not, the trap is essentially non-existent and the drain pan will likely overflow. Make sure the drain pan connection openings are unobstructed. Trap the drain line as shown in Figure 11 for section with negative static pressure. When more than one section has a drain pan, trap each section individually. Do not connect all drains to a common drain line with only one trap. Use the following drain connection recommendations.

AV - Automatic or manual air vent MV - Magnetic valve GV - Gate valve
Coil Piping and Connection General Coil Piping Recommendation Refer to Figure 12 for typical cooling and heating coil piping. Proper installation, piping and trapping is necessary to assure satisfactory heating/cooling coil operation and to prevent operational damage. Water inlet and outlet connections protrude through the coil section side panel. Follow standard piping practices when piping to the coil. Note the following:
1. Support all piping independently of the coils. 2. Provide swing joints or flexible fittings in all connections that are adjacent heating coils in order to absorb thermal expansion and contraction strains. 3. When attaching piping to the coil header, make the connection only tight enough to prevent leaks, the maximum recommended torque is 200ft-lbs. 4. Teflon tape or teflon piping compound should not be used because of its high lubricity, teflon 16
makes it easier to tighten the pipe to the header joint past the point where an effective seal is created, thus damage to the coil could result. 5. "White Zinc" compound is recommended, instead. Caution: Use "Back-up Wrench" when attaching piping to coils with copper headers. Do not use brass fitttings or brass pipe connectors. Brass distorts easily and causes connection leaks.

Start-Up Procedures After completing all items under â€œpreparationâ€? the unit may be started. The following checks and adjustments should be made during initial start-up: 1. Bump-start unit and observe the fan wheel for proper rotation. As indicated by indicated by rotation arrow located on fan housing. 2. Measure the motor voltage and amperage on all phases to ensure proper operation The readings should fall within the range given on the motor nameplate. Never overload the motor. 3. Maximum allowable voltage imbalance is two percent. Voltage imbalance can cause motor overheating and failure. Voltage unbalance is calculated as follows: (L avg -L1)+(L avg-L2 )+(L avg-L3) x100 = %unbalance
2 x L avg L avg = Average line voltage of lines L1, L2 and L3 L1 = Line 1 voltage L2 = Line 2 voltage L3 = Line 3 voltage

Pay particular attention to any vibration, noise or overheating of the fan bearings and motor (bearings may run warm during break in) Note: During break in period, bearing temperature may be 1500F and 1600F. For normal running, bearing temperature is 900F to 1000F. Excessive Vibration-must be corrected to prevent bearing and shaft damage. The trouble shooting section details the common causes for vibration. Determining fan FPM - can be determine by using a strobe-type tachometer, or revolution counter.

readjust to the maximum value.
To measure belt tension, use a belt tensioner as shown in Figure 18. Determine actual deflection by depressing one belt with the belt tensioner and measuring the deflection relative to the other belts or to belt line. Adjust the belt tension to the correct force (Newton) and tighten all setscrews to the proper torques. Figure 17 Belt Tension Measurement
Fan Belt Tension/Alignment Note: Fan belt tension should be checked at least twice during the first day of operation, since there is a rapid decrease in tension until belts are run in. Proper belt tensioning is required to ensure maximum bearing and drive component life and is based on fan brake horsepower requirement.
Belt Tension Measurement Check the belt tension as follows: Measure the span length of the drive (in mm). With a belt tensioner at the center of the span. apply a force K (perpendicular to the span) large enough to deflect the belt 15mm per 1 meter of span. Refer to figure 17. DEFLECTION = SPAN X 15/1000mm The deflection force for the belt should be within the minimum and maximum force shown in the Table A. When the tension drops to the minimum value, 23
