19XR (PIC II) Hermetic Centrifugal Liquid Chillers 50 Hz - Carrier

3.4 - Install machine supports
Typical applications of these units are in refrigeration
systems, and they do not require earthquake resistance.
Earthquake resistance has not been verified.
3.4.1 - Install standard isolation
Figs. 12 and 13 show the position of support plates and shear
flex pads which together form the standard machine support
system.
3.4.2 - Installation of a levelling accessory (if necessary)
Where a floor surface is irregular or uneven, it may prove
necessary to use accessory spring isolators (supplied by Carrier
for field installation) and levelling pads (see Figs. 13 and 15).
Place the unit levelly, using the spring isolator jacking screws.
Use a level at least 600 mm long.

In order to provide adequate, long-lasting support for the unit,
it is essential to choose the right grout and to apply it properly.
Carrier advise using an epoxy-type, pre-mixed, non-shrinking
grout only. Follow the manufacturer’s instructions for applying
the grout.
Check the unit layout plans to determine the required
grout thickness.
Apply wax to the jacking screws to facilitate subsequent
removal from the grout.
The grout must be applied up to the top of the base of the
spring isolator, and there must be no gap in the grout
below the spring isolators.
Allow the grout to dry and set in accordance with the
manufacturer’s instructions before starting up the unit.
Remove the jacking screws from the soleplates once the
grout has set.
