7.3 - Flow control
Evaporator ow switch and chilled water pump interlock
IMPORTANT: On 30XW-V/30XWHV units, the unit water ow
switch must be energised. Failure to follow this instruction
will void the Carrier guarantee.
The water ow switch is installed on the evaporator water inlet
and adjusted by the control, based on unit size and application. If
adjustment is necessary, it must be carried out by qualied
personnel trained by Carrier Service.
7.4 - Evaporator and condenser water box bolt
tightening
The evaporator (and condenser) are of the shell and tube type
with removable water boxes to facilitate cleaning. Re-tightening
or tightening must be done in accordance with the illustration in
the example below.

Sequence 3: 9 10 11 12
Sequence 4: 13 14 15 16
NOTE: Before this operation we recommend draining the
circuit and disconnecting the pipes to be sure that the bolts
are correctly and uniformly tightened.
