Hard Wire Installation
For personal safety and equipment reliability, only a qualied
technician should perform the following procedure.
Note The technician is responsible for installing circuit protection for
incoming power. Before wiring consult the nameplate on the rear of the
chiller. Ensure installation is in accordance with the National Electrical Code
and any other applicable country and local codes.
For ThermoFlex900 through 10000 chillers
Remove the six screws securing the electrical box cover to the chiller.•

Requirements
Ensure that all shipping plugs are removed before installation.
Never connect the process uid lines to your facility water supply or
any pressurized liquid source.
To prevent damage to the chiller's plate exchanger, centrifugal pumps
require a 4.0 gpm (15.1 lpm) minimum ow rate.
P 1 and P 2 pumps are capable of producing 185 psig. Ensure your
plumbing is rated to withstand this pressure at your operating
temperature. An external pressure relief valve is available, see Section 5.
Note Ensure your plumbing installation develops a back pressure to the
