Carrier 16JB - Manual (Page 9)

The integral shipping skids, or base rails, are
normally left on the machine. However, the base
rails may be removed, if desired, but not until the
machine is in final position. When isolation pads
are used, they should be located under the corners
of the machine, atop soleplates with 1/2-in. min­
imum thickness (see Fig. 10). The soleplate ensures
machine contact on the floor only at the corners
when base rails are left on. Shims may be inserted
under the soleplates for leveling the machine.
Grouting is optional.

Explosionproof Machines — 16JB standard absorp­
tion machines can be factory equipped with
explosionproof
electric motors and controls
suitable for Class 1, Group D hazardous locations
specified by the National Electrical Code. Modi­
fications to the standard control system are
described in the controls application publications.
Outdoor Installation — Outdoor installation of the
16JB absorption machine creates a number of
special problems which must be resolved. Such
applications should be considered only when the
customer
has qualified operating personnel,
familiar with the maintenance of mechanical equip­
ment located outdoors. Standard machines require
protection
from weather. A simple, heated
structure is preferred. If this is not possible,
protection from the weather must be provided by
machine modifications.
WEATHERPROOFING -- Pneumatic control sys­
tems are recommended for outdoor installations.
Controls can be factory furnished to meet NEMA
No. 4 Waterproofing Specifications.
FREEZE PROTECTION — When the machine area
may be subjected to temperatures below 40 F and
if the machine is to be shut down for an extended
time during these low-temperature periods, all
water circuits and tube bundles should be drained,
then filled with ethylene glycol. Table 5 lists
storage volumes of 16JB header and tube bundles.
This data can be used when calculating the
quantity of ethylene glycol needed to provide
adequate freeze protection.
