CHAPTER 2 INSTALLATION
2.1 INTRODUCTION
This chapter provides instructions for:
• Receiving the heat exchanger and installing it in a suitable location (2.2)
• Piping into the steam and water systems (2.3)
• Installing and connecting the Electronic Control System (2.4)
2.2 RECEIVING, UNPACKING AND INSTALLING
To prepare the heat exchanger for installation:
1. Carefully uncrate the heat exchanger.
2. Set the heat exchanger upright using a block and tackle or hoist attached to the lifting lugs (eye-bolts)
on the top head.
CAUTION
ALWAYS USE THE LIFTING LUGS to lift and/or move the heat exchanger.
3. To simplify in-place maintenance, install the heat exchanger in a location having the following
clearances:
a. Horizontal clearance: At least two (2) feet all-around
b. Headroom: At least six (6) feet measured upward from the top of the upper shell flange.
The dimensions of the AERCO Model DW-heat exchangers are presented in Figures 2-1 through 2-3.
4. Secure the heat exchanger in place, preferably, by attaching it to the floor. If you use piping to secure
the heat exchanger in position, be sure to include ample provision for pipe expansion.
