Setting the Unit
The unit must be installed on a 4 inch to 6 inch housekeeping pad to ensure proper condensate drainage.
If anchoring the unit, refer to the dimensional drawings in Appendix F for anchor locations. Two lifting lugs
are provided at the top of the heat exchanger as shown in Figure 2-2. USE THESE TWO LUGS TO LIFT
AND MOVE THE UNIT. Remove the top panel from the unit to provide access to the lifting lugs. Remove
the four (4) lag screws securing the unit to the shipping skid. Lift the unit off the shipping skid and position
it on the 4 inch to 6 inch housekeeping concrete pad (required) in the desired location.

In multiple unit installations, it is important to plan the position of each unit in advance. Sufficient space for
piping connections and future service/maintenance requirements must also be taken into consideration.
All piping must include ample provisions for expansion
.

WATER INLET AND OUTLET PIPING
The locations of the 2" NPT cold water inlet and hot water outlet piping connections are shown in Figure
2-3. Flow rates through the unit are limited to 30 gpm continuous and 40 gpm intermittent.
Shut-off valves and union connections must be installed in the inlet and outlet lines for
maintenance. The use of dielectric unions is recommended.
NOTE:
All piping must be arranged so that it does not interfere with removal of any covers, inhibit
service or maintenance, or prevent access between the unit and walls, or another unit.
