prolonged shutdoWn
If the chiller is to be shut down for an extended period of
time (for example, over the winter season), the following
paragraphs outline the procedure to be followed.
1. Test all system joints for refrigerant leaks with a
leak detector. If any leaks are found, they should be
repaired before allowing the system to stand for a
long period of time.
During long idle periods, the tightness of the system
should be checked periodically.
2. If freezing temperatures are encountered while the
system is idle, carefully drain the cooling water from
the cooling tower, condenser, condenser pump, and
the chilled water system-chilled water pump and
coils.
Open the drains on the evaporator and condenser liq-
uid heads to assure complete drainage. (If a Variable
Speed Drive, drain its cooling system. If Solid State
Starter equipped drain liquid from starter cooling
loop.)
3. If freezing temperatures are encountered for peri-
ods longer than a few days, the refrigerant should
be recovered to containers to prevent leakage from
O-ring joints.
4. On the
SETUP
Screen, disable the clock. This con-
serves the battery.
5. Open the main disconnect switches to the compres-
sor motor, condenser water pump and the chilled
water pump. Open the 115 volt circuit to the Control
Center.
