3-4 I Installation
Rigging
The unit has a structural steel base with casters to facilitate easy movement and position-
ing. Follow proper rigging methods to prevent damage to components. Avoid impact load-
ing caused by sudden jerking when lifting or lowering the unit. Use pads where abrasive
surface contact may occur. Use the frame supporting the unit for positioning it with a
crane or a forklift.
Fluid Distribution Piping
Proper insulation of any cooling fluid system where the supply cooling fluid temperature
is below the dew point is crucial to prevent condensation. In most cases this will apply to
systems where the supply temperature is 55°F {13°C} or colder. The formation of conden-
sation on water piping caused by the state change of the water from gas to liquid adds a
substantial heat load and becomes an additional burden for the cooling system.
The importance of properly sized piping between the cooling system and the temperature
control unit and between the temperature control unit and the process cannot be over-
emphasized. See the ASHRAE Handbook or other suitable design guide for proper pipe
sizing. In general, run full size piping out to the process and then reduce the pipe size
to match the connections on the process equipment. One of the most common causes of
unsatisfactory unit performance is poor piping system design. Avoid long lengths of hoses,
quick disconnect fittings, and manifolds wherever possible as they offer high resistance to
water flow. When manifolds are required, install them as close to the use point as possible.
Provide flow-balancing valves at each machine to assure adequate water distribution in the
entire system. We recommend shut-off valves at each machine to allow for isolation of the
unit.
