INSTALLATION

Unpacking

SUPERCHANGER units (with optional shroud) are bolted

to and shipped assembled on a skid. Other optional items, if

supplied, are packed separately. All items should be checked

against packing lists.

SHOULD ANY PARTS BE MISSING OR DAMAGED,

IMMEDIATELY NOTIFY:

Tranter, Inc.

P.O. Box 2289

Wichita Falls, TX 76307

940-723-7125

Recommended Procedures

All frame models are provided with special lifting eyeholes for

transportation and installation by crane. Rigidly set all models on

the ﬂoor by means of foundation bolts. The following installation

tips are also recommended:

1. Level the unit.

2. Locate the unit in an area that is not congested with piping

and other equipment. For units with nozzles on the movable

frame, refer to Figures 39 and 40 on page 29.

3. Provide three feet of working area around the unit.

4. The piping system must allow for thermal expansion. This

can be accomplished inherently within the piping layout or

by ﬂexible connections.

5. Debris can cause damage to the gaskets. The gasket areas

must be free from sand, gravel, pieces of iron, etc. before the

unit is closed.

6. Lubricate the tie bolts.

7. Tighten all tie rod nuts. Tighten the unit to plate pack

dimension per assembly drawings prior to making any

assembly connections.

8. Uniformly tighten the plate pack. (See tightening instructions

following.)

9. Flush connecting piping of all debris prior to “hook-up” with

the heat exchanger.

10. Correctly center gaskets inserted between pipe ﬂanges.

11. Do not apply valve and piping loads to the nozzles. Use

pipe supports.

12. Install shutoff valves at all nozzle locations.

13. Place vent valves for draining at the highest possible point.

14. Provide pumps sending liquid into the SUPERCHANGER

with throttling valves.

15. Install a safety relief valve if the maximum pressure output

of the pump is greater than that of the heat exchanger.

16. When a pressure control valve is installed, place it at the

inlet of the heat exchanger, even if a pressure control switch

is provided.

CAUTION: Do not expose plate and frame heat

exchangers to continuous vibration and/or high

frequency cyclic on/off operation since damage

from fatigue may occur. Do not use metering and

pulsating type pumps. If the SUPERCHANGER

unit is used in cyclic operation, the equipment

should be tightened to the minimum dimension

(see Table 3) to prevent fretting failure. Contact the

factory for assistance.
