The optional evaporative cooling module for packaged indirect-fired system Model Series RGBL, RPBL, SSCBL, PGBL, blower cabinet Model RBL, and direct-fired makeup air Models ADF/ADFH 700/1200 is factory assembled but requires field

installation. Evaporative cooling module Option AS3 includes 6” rigid cellulose media; Option AS4 includes 12" rigid cellulose media; Option AS5 includes 6" rigid glass fiber media; and Option AS8 includes 12" rigid glass fiber media. The

base parts for supporting the evaporative cooling module and the transition duct for connecting it to the unit are shipped with the module for field assembly and installation. If optional moisture elimination pads, a drain and fill kit, and/or a water hammer arrestor are to be included in the installation, they also require field installation.

Indoor Installation Note: The evaporative cooling module cannot be suspended;

it must be placed on a platform. If the installation is not conducive to providing a platform for the optional evaporative cooling module to attach directly to the cabinet, install a compatible Reznor ® Model REC evaporative cooling module which also must be mounted but requires a field-fabricated transition duct and can be located further away. All evaporative cooling modules require outside air.

o If the evaporative cooling module is being installed indoors (Model SSCBL,

PGBL, or ADF/ADFH 700/1200), outside makeup air must be provided.

o If optional shipped-separate equipment will be included (Drain and Fill Kit,

Freeze Protection Kit, Moisture Elimination Pads, and/or Water Hammer Arrestor), check to be sure that these parts are available for installation.

o Make certain the roof or platform is capable of handling the additional load of

a cooling module with a full reservoir.

Weights of Evaporative Cooling Module - With Wet Media & Full Reservoir

Module with 6" rigid cellulose media (Opt AS3) ............... 379 lbs (172 kg)

Module with 12" rigid cellulose media (Opt AS4) ............ 431 lbs (195 kg)

Module with 6" rigid glass fiber media (Opt AS5) ............. 420 lbs (191 kg)

Module with 12" rigid glass fiber media (Opt AS8) ........... 514 lbs (233 kg)

o Make certain the surface is level and free of debris where cooling module will

o Do not mount directly on soft tar roofs where the legs could sink and tilt the

cooler. Provide a weather-resistant, solid wood or metal base under the cooling module support base.

o Make certain that there will be adequate clearance between the bottom of the

reservoir and the roof or platform to allow for drain and overflow pipe connections.

4. Base and Transition Duct Installation Instructions

FIGURE 1- Assembled Base for Evaporative Cooling Module

Adjustable Leg Height

16” (406mm) Maximum 9” (229mm) Minimum

Attach the evaporative cooling module after the makeup air unit is in its permanent

location. Do not install the evaporative cooling module and connecting duct while the blowers are in operation. Steps 2-11 are illustrated on FIGURE 2, page 3.

Steps 12-20 are illustrated in FIGURE 4, page 4. FOLLOW EACH STEP IN ORDER.

STEP 1:

1) Be sure all preparations have been made. Review Preparation Checklist, pages

1 and 2.

Assembling Base, FIGURE 1 & STEPS 2-5, FIGURE 2:

2) Using four bolts and nuts per leg, fasten the two leg halves (ITEM 4) together. See FIGURE 2, Step #2. The top flange of the assembled legs should be level

with the bottom of the system cabinet. Adjust legs to proper height and tighten bolts securely. Assemble all four legs.

3) Approximately two feet (610mm) from the air inlet side of the cabinet, posi-

tion the four assembled legs in a rectangular pattern corresponding to the size of the cooler. Depending on the type of surface, it may be necessary to set the legs on a weather-resistant, solid wood or metal base. Check again to be sure that the top of the legs are level with the bottom of the makeup air system cabinet.

4) Place rail sides (ITEM 3) on the inside of the top flanges of the leg assemblies.

Using the bolts and nuts provided, bolt the side rail to the top three holes located on the legs just below the top flange. Repeat on the remaining three legs. Tighten nuts securely.

5) Place the rail ends (ITEM 2) on the inside of the top flange of the leg assem-

blies. Bolt the end rail to the top three holes located on the legs just below the top flange. Repeat on the remaining three legs. Tighten nuts securely.

6) Carefully lift the evaporative cooling module (ITEM 1) from both ends and place it on the

completed base assembly. Be certain that the cooling module is level and all base assembly bolts are secure.

7) Attach front top cover (ITEM 5) to cooling module, as shown in STEP #7 using 13 of the

# 10 x 1/2" long sheetmetal screws. There will be three screws per side and seven screws across the top.

8) Attach transition duct sides (ITEM 7) to duct top (ITEM 6) using eight, #10 x 1/2" long sheetmetal screws. As shown in STEP #8, there will be four screws per side.

9) Fasten the duct bottom (ITEM 8) to the transition duct sub-assembly begun above by following STEP #9, using eight of the #10 x 1/2" long sheetmetal screws

provided. Again, there will be four per side.

10)If the packaged heating system is a “BL” 500, 600, 700 or 1050 size, the duct

extensions (ITEM 9) must also be installed on the transition duct. If the packaged

heater is a “BL” 400, 800, or 1200 size, an RBL, or an ADF/ADFH, skip STEP

11 and continue with STEP 12.

11)There are two sizes of the duct extensions. One is used to fit the “BL” 500 or 600

size heaters; one fits the 700 and 1050 size heaters. To fasten the duct extension (ITEM 9) to the transition duct assembly, use 14 #10 x 1/2" long metal screws as

shown in STEP #11. Five screws will be used on each side of the extension and

one up through the bottom of the extension.

Assembling Transition Duct (cont’d)

Attaching Transition Duct and Cooling Module to System Cabinet (FIGURE 4, STEPS 12-

21):

FIGURE 3 Assembled Transition Duct

12)Following Step #12A, remove the screws from along the top rear lip of the blower cabinet panel. Slip the transition duct flange underneath the cabinet top edge and loosely insert two screws through the top edge, through the transition duct flange, and into the cabinet end panel. Follow STEP #12B.

13)If the transition duct has duct extensions (FIGURE 2, ITEM 9), insert the duct extension

mounting flanges into the slots on the cabinet end panel.

14)With the transition duct attached to the cabinet, carefully tilt the transition duct upward

enough to clear the cooler reservoir pan and slide the evaporative cooling module underneath the catch pad mounting trough. Squeeze the cooling module and transition duct assembly into the system cabinet until a tight fit is obtained.

15)Following STEP #15, line up the holes in the cooling module corner leg with the holes in

the transition duct sides. Using five #10 x 1/2" long sheetmetal screws per side, fasten the transition duct sides to the cooling moduler.

16)Following STEP #16, fasten the transition duct top lip to the front top cover of the

cooling module with seven of the #10 x 1/2" long sheetmetal screws provided.

17)With the cooling module and transition duct properly positioned on the blower cabinet, tighten the two screws loosely inserted in STEP 12B. Insert and tighten screws in the

remaining holes along top edge of cabinet.

NOTE: When attaching the transition duct to the cabinet (STEP 18 or 19), you may find it easier with the media pads removed. See FIGURES 5 and 7 and the corresponding
