ATECO Site Supervision & Sys tem Cert i f icat ion

An ATECO site supervisor is an important and critical part of the DCA installation. The Supervisor

will assist the on-site contractor that will be responsible for installing the DCA. This assistance

includes training the contractor in the nuances of the installation and thereby ensuring proper

installation. Further, the Supervisor will be available to address any questions that may occur

during installation.

Preparing Materials

Assemble and inspect reel, cable, grounding strap and wire guide. Do not remove the shrink

wrap on the reel.

Layout and Tank Preparation

If an installation drawing with the RES2000 quantity and location is provided by

ATECO, mark the location(s) of where the RES2000 should be placed. If a drawing

is not provided, the RES2000 should be equally spaced from each other (i.e. if 4

RES2000s were purchased for one 100-ft (30m) diameter tank, each RES2000 will

be placed 90apart or roughly 78 1/2-ft (24m) on the circumference of the tank.).

Mark these locations. Ideally, the RES2000 will be placed on the highest possible

location of the tank, the swash plate or fire suppression plate. If the RES2000 can

not be mounted on the swash plate and clearance can not be achieved by mounting

the RES2000 directly on the tank wall, use the Horizontal Bracket (provided).

Note: Ensure that the RES2000 will not interfere with the tank roof when fully filled.

Finally, if any obstacles or interferences are encountered, contact the ATECO site

Supervisor for assistance.

Attaching the RES2000 to the Tank Wall

The RES2000 comes supplied with bolts, nuts and washers for attaching to the tank

wall (or fire suppression plate). For the RES2000 attachment, 49/16 diameterholes need to be field drilled in the tank wall using the RES2000 bracket as a

template. Scrape paint and rust from around the drilled holes to bare metal. Apply

ATECOtra Shield (supplied) to both sides of the hole to prevent rusting.

Using the supplied hardware, secure the RES2000 mount to the tank wall and apply

ATECOtra Shield to the hardware. Next install the RES2000 reel to the supporting

bracket. The RES2000 reel must rotate freely in this supporting bracket.

Mounting Options:

Drawing RES2000 Mount, inserted at the end of this document, comparesthe two ways the RES2000

Assembly can be mounted. This can be used as an aide to assist the customer in

determining which installation option is best suited for your application;

directly to the vertical tank wall orutilizing the supplied Horizontal Rim Angle.

Using the supplied Horizontal Rim Angle:

Figure 2 shows the items used in utilizing the Mounting Bracket (noteall

hardware shown below provided).

Figure 2: Horizontal Mounting Bracket

With the Horizontal Mounting Bracket, the ground attachment point should be as close to the

tank wall as possible; shown in Figure 3. The use of this mounting bracket requires that 2

9/16 diameter holes be field drilled in the rim angle using the Rim Angle Bracket as. The .

connection is shown in Figure 3, below

Grounding and bonding

The ground strap is pre-drilled for connection to the tank roof. The RES2000 will operate properly

on roofs where the ground lug can be installed directly below the RES2000 and within 18 of the

tank wall as shown in Figure 3.The attachment point on the floating roof must align vertically with the center of the braidedcable ground wire, as shown in Figure 4. To ease vertical alignment, the RES2000 should beinstalled when the tank is at its fullest capacity. A plumb bob can be used for best possible

results (cautiona plumb bob should be utilized when the wind is calm).The RES2000 cable should be tensioned such that when the floating roof is at the top (full) position,

a minimum number of pre-tension rotations are applied to the spool. This spring pre-tensionwould need to be adjusted in the field. See the table below to determine the amount of pretension

required:

If the tank is not full, the amount of pretension rotation to be applied should be enough to re-

coil

the cable if fully extended. Once the RES2000 mount or RES2000 mount and Rim Angle

Bracket

are

securely attached to the tank wall, insert the RES2000 reel on the mount and secure. The

following

steps should be implemented:

1. Prior to removing the shrink-wrap from the cable, turn the RES2000 reel back and forth to

make sure that the spring is in its most relaxed state.

2. Rotate the RES2000 reel against the spring's tension 12 times (complete rotations - 12 x

360)

to pretension the system.

3. Without allowing the spring motor to recoil, carefully remove the shrink-wrap (do not use

sharp objects to cut shrink wrap).4. Un-reel the RES2000 cable to the top of the foam dam of the tank.

5. Secure the supplied ground strap to the tank and RES2000 cable.

Finally, coat all mechanical ground connections with lectra Shield (supplied). Follow the

manufacturers' written instructions exactly. If you encounter any problems, contact the

ATECO Site

Supervisor immediately or the Engineering Department in the absence of a Site Supervisor.
