5. The first port on the left includes two pieces of 18-2 that should be connected to each
slave
module in both evaporators at #1 and #2 terminals. These connections will shut down
the system if there is
ever a high water condition in either evaporator. They are connected
parallel to each safety float. Also
in the first port there is a piece of 18-6 that is color coded per
our standard operating instructions to be affixed
to the VH620 Keyboard Display, the temp
sensor, and the humidity sensor (see Page 6 in “Power
To the Evaporator”). Second port
from the left is power, 14-2 with ground, 115V. Lastly the third and
fourth outlets hold each 14-6
jumper cable, that is also color-coded. These run to each evaporator slave
module inside of
each stainless steel enclosure.
6. Make sure that the unit is covered tightly with each cover.

7. From left to right. The first two terminals should be connector to the 18-2 leads from
port one in the master control module. Terminals 3, 4/5 (one white lead), 7,8.9 and 10 will be
connected to each color coded lead from the 14-6 cable that you run from the Master Control
Module.
Replace the cover firmly.

8. Wrap the TXV and refrigeration solenoid with ESP Heat block (#HB34) or comparable
product.
Braze the refrigerant solenoid to the liquid line. Remove the txv bulb and braze in the
suction line to the line exiting the
condenser. Re-attach the bulb when cool.
