OPTIONAL DECORATIVE TAMPERPROOF

ENCLOSURE (LOUVERED & WIRE GRILLE)

General

A louvered tamperproof enclosure is available for chiller

for the prime purpose of deterring unauthorized access

to components of the chiller.
Kits 475-04262-002 is the decorative/tamperproof en-

closure which consists of louvered sheet metal panels

along with mounting hardware. This kit has a further

purpose of presenting a pleasing appearance to the

chiller when it is located in a highly visible area. Two

kits must be installed to complete the installation.

Installation

1. Refer to Fig. 46 and the associated parts list. Before

starting installation, all of the items should be identi-

fied by comparing with Fig. 47.

2. All holes for mounting kit parts are provided in both

the chiller frame and the added supports; therefore,

it should be unnecessary to drill holes.

3. Install the louvered panels using the proper hardware

and supports. Refer to Fig. 47 and the Parts List for

placement of the panels and the proper hardware

required. Discard existing grilles to attach the lou-

vered panels where necessary.

4. Notch grilles to suit water connection and wiring har-

nesses as needed.

5. If the High Ambient Sunshield Kit or Disconnect Op-

tion is installed, field adaption will be required where

parts of the kits interfere. Touch up exposed metal

parts to prevent rust.
