PANEL CHECKS
(Power On – Both System Switches “OFF”)
q
1. Apply 3 phase power and verify its value (See
Fig. 20).
q
2. Apply 115VAC and verify its value on the termi-
nal block in the lower left of the Power Panel.
Make the measurement between terminals 5
and 2 of TB1 (See Fig. 20.). The voltage should
be /- 10%.
q
3. Assure the heaters on each compressor are on.
Allow the compressor heaters to remain on a
minimum of 24 hours before startup. This is im-
portant to assure that no refrigerant is in the com-
pressor oil at start-up!
q
4. Program the dip switches on the microprocessor
board for the desired operating requirements. See
Page 80. OPEN = Left side of switch pushed down.
CLOSED = Right side of switch pushed down.

Verify the selections by pressing the OPTIONS
Key on the control panel. Check them off.
CAUTION: Damage to the chiller could result if
switches are improperly pro-
grammed.
q
5. Program the required twenty-two operating val-
ues into the micro for cut-outs, safeties, etc. and
record them in the chart below. See Page 88.
If Default Values are desired for programming
convenience, press the PROGRAM key, 6140,
and ENTER. This loads default values. Record
these values in the chart below.

q
6. Program the Chilled Liquid Temp/Range and
record:
CR = ________ to _________ °F (°C)
Target = ____________ °F (°C)
Keep in mind that the Target temperature dis-
played by the micro should equal the desired
leaving water temperature.
q
7. Assure that the CLK jumper J18 on the Micro-
processor Board is in the ON position (Top 2
pins).
q
8. Set the Time and Date.
q
9. Program the Daily Schedule start and stop times.
