Check Out
Once the unit is installed, it is advisable to check the
following controls and mechanical operations of the
freezer and to make any necessary adjustments. If
applicable, repeat these checks for the second
freezing cylinder on double head units.
Controls
Place the control switch in the “AUTO” position. The
main refrigeration system will operate (compressor,
beater motor, and the condenser fan). The dial light
and the mix low indicator will be illuminated.
Figure 1
If the freezer is water cooled, the automatic water
valve will begin to open and cold water will flow into the
condenser. This will remove heat from the refrigerant.
As the water flows into the open trap drain, it should be
warm to the touch. Place the control switch in the
“OFF” position.
Beater Rotation
Beater rotation must be clockwise as viewed
looking into the freezing cylinder.
Note: The following
procedures
must
be
performed by an authorized Taylor service
technician.
To correct rotation on a three- phase unit, interchange
any two incoming power supply lines at the freezer
main terminal block only. To correct rotation on a
single- phase unit, exchange leads inside the beater
motor. (Follow the diagram printed on the motor.)
Electrical connections are made directly to the
terminal block provided in the main control box located
behind the service panel.
Refrigerant
In consideration of our environment, Taylor
uses only earth friendly HFC refrigerants. The HFC
refrigerant used in this unit is R404A. This refrigerant
is generally considered non-toxic and non-flammable,
with an Ozone Depleting Potential (ODP) of zero (0).
However, any gas under pressure is potentially
hazardous and must be handled with caution.
NEVER fill any refrigerant cylinder completely with
liquid. Filling the cylinder to approximately 80% will
allow for normal expansion.
Use only R404A refrigerant that conforms to
the AHRI standard 700 specification. The use of any
other refrigerant may expose users and operators to
unexpected safety hazards.
Refrigerant liquid sprayed onto the skin may
cause serious damage to tissue. Keep eyes and skin
protected. If refrigerant burns should occur, flush
immediately with cold water. If burns are severe, apply
ice packs and contact a physician immediately.
Taylor reminds technicians to be cautious of
government laws regarding refrigerant recovery,
recycling, and reclaiming systems. If you have any
questions regarding these laws, please contact the
factory Service Department.
WARNING: R404A refrigerant used in
conjunction with polyolester oils is extremely moisture
absorbent. When opening a refrigeration system, the
maximum time the system is open must not exceed 15
minutes. Cap all open tubing to prevent humid air or
water from being absorbed by the oil.
