Low Profile Forced Draft Towers, Coolers and Condensers

Method of Shipment

LP/LR forced draft units are shipped fully assembled. Miscellaneous items, such as sealer, self-tapping screws and any other re-

quired materials, are packaged and placed inside the pan for shipment.

NOTE: All hoods and attenuation packages are factory inspected prior to shipment to verify proper t for rigging. Please take extra

care to handle and rig unit section per the instructions of this manual to avoid possible distortion and poor casing alignment. It is

advisable to check each section upon receipt and during each lift to ensure that the factory alignment has not been altered. Should

the eld inspection indicate the section alignment (“square”) has been altered, please contact the factory or your local EVAPCO

representative for additional instructions to obtain proper section t.

Storage

Do not place tarps or other coverings over the top of the units if the units are to be stored before installation. Excessive heat can

build up if the units are covered causing possible damage to the PVC eliminators. For extended storage beyond six months rotate

the fans and fan motor shaft(s) monthly. Also, the fan shaft bearings should be purged and regreased prior to start-up.

General

For extended lifts, or where hazards may exist, it is recommended that safety slings and spreaders be employed for safety. Refer to

the extended lift information in this bulletin.

International Building Code Provisions

The International Building Code (IBC) is a comprehensive set of regulations addressing the structural design and installation

requirements for building systems- including HVAC and industrial refrigeration equipment. As of June 2008, all 50 states plus

Washington D.C. have adopted the International Building Code. The code provisions require that evaporative cooling equipment

and all other components permanently installed on a structure must meet the same seismic design criteria as the building.

The LPT Series Cooling Towers, LR Series Coolers and Condensers are IBC 2012 compliant up to 1g with standard construction

and up to 5.12g with additional structural modications.

All items attached to the EVAPCO LPT Cooling Tower, Evapco LR Closed Circuit Cooler or LR Evaporative Condenser must be

independently reviewed and isolated to meet applicable wind and seismic loads. This includes piping, ductwork, conduit, and

electrical connections. These items must be exibly attached to the Evapco unit so as not to transmit additional loads to the

equipment as a result of seismic or wind forces.

Structural Steel Support

Two structural “I” beams running the length of the unit are required for supporting the unit. These beams should be located

underneath the outer anges of the unit as shown in Figure 1. See Table 1 for Steel Support Dimensions. Table 1 lists units

according to the nominal plan area of their heat transfer section. Overall dimensions will be different.

Mounting holes, 3/4” (19 mm) in diameter, are located in the bottom ange for bolting to the structural steel. Refer to the recommended

structural steel support drawing and certied print for exact bolt hole location. Bolt the bottom section to the steel support before

rigging any hoods or attenuation.

Beams should be sized in accordance with accepted structural practices. Maximum deection of the beam under the unit should

be 1/360 of the unit length, not to exceed 1/2” (13 mm). Deection may be calculated by using 55% of the operating weight as a

uniform load on each beam (see certied print for operating weight).

Low Profile Forced Draft Towers, Coolers and Condensers

The supporting “I” beams should be level to within 1/8” (3 mm) in 6’ (2 m) before setting the unit. Do not level the unit by shimming

between the bottom ange and the beams as this will not provide proper longitudinal support.

NOTE: Consult IBC 2012 for required steel support layout and structural design.

Rigging the Main Unit

Lifting devices are located on the sides of the unit near the bottom as shown in Figure 2a. It is recommended that units be lifted

using a boom oriented along the length of the unit with the cables straddling the unit at the lift points (Figure 2a). An alternative

method is to lift the unit with a single hook, lashing the cables to the lift points on the unit directly (Figure 2b). Spreader bars are

necessary in both cases to prevent damage to the sides of the unit.

When a boom is used, the distance “A” between the lift points on the boom should be set equal to the distance between the lift points

on the unit and the crane hook must be located a minimum distance “H1” above the top of the unit as shown in Figure 2a.

When no boom is used, the crane hook must be a minimum distance “H2” above the lifting points on the unit as shown in Figure 2b.

Extended Lifts

The recommended method for extended lifts is to use slings under the unit (Figures 3a and 3b). Safety slings, spreaders and skids

should be removed before nal positioning of the unit.

NOTE: Always use safety slings for extended lifts or where any safety hazard exists.

Applying Sealer Tape

If the unit was shipped with optional discharge attenuation or discharge hoods sealer tape must be applied prior installation of

the section. Once the unit has been set on the supporting steel and bolted in place, wipe the top anges to remove any dirt or

moisture. Place sealer tape over the mounting hole centerline on the side anges. Apply two strips of sealer tape, one partially

overlapping the other, on the end anges.

The sealer tape should overlap on the corners as shown in Figure 4. Do not splice the sealer tape along the end anges and

preferably not on the side anges if it can be avoided. Always remove the paper backing from the sealer tape.

Rigging and Assembling Discharge and Intake Accessories

Intake sound attenuators and discharge hoods/discharge attenuators are not assembled to the main unit when shipped and must

be separately rigged and assembled in the eld. Four accessories fall into this group - discharge hood (may be straight or tapered),

discharge attenuation, fan-end sound attenuator and fan side attenuators. These are shown mounted in Figure 5 and construction

details are referenced to Figures 7, 9 and 11 respectively.

Final Assembly and Start-up Details

Shipping Materials - Remove any wood chocks, spare parts, or miscellaneous items that have been placed inside the unit for

shipping purposes. Clean all debris from the basin.

Pump Discharge Line - Connect the riser pipe from the pump discharge on the pan-fan section to the riser pipe on the coil section

using the exible connection and hose clamps provided.

Bleed-off Line - A bleed-off line and valve are installed on the unit when shipped with a pump. On units shipped without a pump

(remote sump applications) make sure a bleed-off line and valve are properly sized and installed on the discharge side of the pump

and connected to a convenient drain. In either case, the bleed-off valve should be fully open.

Strainer - Check the strainer in the basin to ensure that it is in its proper location over the pump suction as shown in Figures 12a

and 12b.

Screens - Protective air inlet screens are provided across the front of the fan section of all models. Screens or panels are provided

on the bottom of the fan section.

Float Valve Adjustment - The oat valve is pre-set at the factory, however adjustment should be checked after rigging. The

oat valve should be adjusted so that the center of the oat is 1” (1-2 cm) below the center of the overow connections when

the valve is in the fully closed position. Raise or lower the oat by using the wing nuts on the vertical threaded rod. Do not

adjust the horizontal rod. During normal operation, the water level will drop 3” to 4” (8-10 cm) below the overow in condensers

and coolers; and to approximately 5” to 6”( 12-15 cm) below the overow in cooling towers.

See Table 5 for normal operating level for the LR and LP style units.

Fan Rotation - Bump start and check the fans for proper rotation. Directional arrows are placed on the outside of centrifugal fan

housings or on the inside of axial fan cylinders.

Pump Rotation - Bump start and check the pump for proper rotation. Directional arrows are found on the pump impeller housing.
