2 Model 793 To the Installer
Water Connections
(Water Cooled Units Only)
An adequate cold water supply must be provided
with a hand shut-off valve. On the underside rear of
the base pan, two 3/8” I.P.S. (for single-head units)
or two 1/2” I.P.S. (for double-head units) water
connections for inlet and outlet have been provided
for easy hook-up. 1/2” inside diameter water lines
should be connected to the unit. (Flexible lines are
recommended, if local codes permit.) Depending on
local water conditions, it may be advisable to install
a water strainer to prevent foreign substances from
clogging the automatic water valve. There will be
only one water “in” and one water “out” connection
for both single-head and double-head units. DO
NOT install a hand shut-off valve on the water “out”
line! Water should always flow in this order: first,
through the automatic water valve; second, through
the condenser; and third, through the outlet fitting to
an
open trap drain.
A back flow prevention device is
required on the incoming water connection side.
Please refer to the applicable National, State, and
local codes for determining the proper configuration.
Electrical Connections
In the United States, this unit is intended to be
installed in accordance with the current edition of the
National Electrical Code (NEC), ANSI/NFPA 70
which governs the installation of the unit at the local
governmental level.
The purpose of the NEC code is the practical
safeguarding of persons and property from hazards
arising from the use of electricity. This code contains
provisions considered necessary for safety.
In all other areas of the world, the unit should be
installed in accordance with the existing local codes.
Please contact your local authorities.
Each unit requires one power supply for each data
label on the unit. Check the data label(s) on the unit
for branch circuit overcurrent protection or fuse,
circuit ampacity, and other electrical specifications.
Refer to the wiring diagram provided inside of the
electrical box for proper power connections.
FOLLOW YOUR LOCAL ELECTRICAL CODES!
CAUTION: THIS UNIT MUST BE
PROPERLY GROUNDED! FAILURE TO DO SO
CAN RESULT IN SEVERE PERSONAL INJURY
FROM ELECTRICAL SHOCK!
An equipotential grounding lug is provided with
this unit. Some countries require the grounding lug
be properly attached to the rear of the frame by the
authorized installer. The installation location is
marked by the equipotential bonding symbol (5021
of IEC 60417-1) on both the removable panel and
the unit's frame.
S
Stationary appliances which are not
equipped with a power cord and a plug or
another device to disconnect the appliance
from the power source must have an all-pole
disconnecting device with a contact gap of
at least 3 mm installed in the external
installation.
S
Appliances that are permanently connected
to fixed wiring and for which leakage
currents may exceed 10 mA, particularly
when disconnected or not used for long
periods, or during initial installation, shall
have protective devices such as a GFI, to
protect against the leakage of current,
installed by the authorized personnel to the
local codes.
S
Supply cords used with this unit shall be
oil-resistant, sheathed flexible cable not
lighter than ordinary polychloroprene or
other equivalent synthetic
elastomer-sheathed cord (Code designation
60245 IEC 57) installed with the proper cord
anchorage to relieve conductors from strain,
including twisting, at the terminals and
protect the insulation of the conductors from
abrasion.
If the supply cord is damaged, it must be
replaced by an authorized Taylor service
technician in order to avoid a hazard.
