Section 1 To the Installer

The following are general installation instructions. For
complete installation details, please see the check out
card.

Installer Safety

In all areas of the world, equipment should be
installed in accordance with existing local codes.
Please contact your local authorities if you have any
questions.

Care should be taken to ensure that all basic safety
practices are followed during the installation and
servicing activities related to the installation and
service of Taylor equipment.

S Only authorized Taylor service personnel

should perform installation and repairs on
the equipment.

S Authorized service personnel should consult

OSHA Standard 29CFRI910.147 or the
applicable code of the local area for the
industry standards on lockout/tagout
procedures before beginning any installation
or repairs.

S Authorized service personnel must ensure

that the proper PPE is available and worn
when required during installation and
service.

S Authorized service personnel must remove

all metal jewelry, rings, and watches before
working on electrical equipment.

The main power supply(s) to the equipment
must be disconnected prior to performing any repairs.
Failure to follow this instruction may result in personal
injury or death from electrical shock or hazardous
moving parts as well as poor performance or damage
to the equipment.

Note:Allrepairsmustbeperformedbyan
authorized Taylor Service Technician.

Site Preparation

Review the area the unit is to be installed in before
uncrating the unit making, sure that all possible
hazards the user or equipment may come into have
been addressed.

For Indoor Use Only: This unit is designed to operate
indoors, under normal ambient temperatures of
70_-75_F(21_-24_C). This unit has successfully
performed in high ambient temperatures of
104_(40_C) at reduced capacities.

This unit must NOT be installed in an area

where a water jet or hose can be used. NEVER use a
water jet or hose to rinse or clean the unit. Failure to
follow this instruction may result in electrocution.

Uncrate the unit and inspect it for damage. Report any
damage to your Taylor Distributor.

This unit must be installed on a level surface
to avoid the hazard of tipping. Extreme care should be
taken in moving this equipment for any reason. Two or
more persons are required to safely move this unit.
Failure to comply may result in personal injury or
equipment damage.

The Model 20 comes equipped with four casters; two
are locking. To install the casters, tip the unit back to
expose the front caster pads. (Note: The front of the
unit contains the control switch.) Install both locking
casters. Block and lock both front casters. Tip the unit
forward and install the two remaining casters.

This unit has many sharp edges that can

cause severe injuries.

Model 20

This piece of equipment is made in the USA and has
USA sizes of hardware. All metric conversions are
approximate and vary in size.

Air Cooled Units

DO NOT obstruct air intake and discharge openings:

Always allow a minimum of 3” (76 mm) clearance
around all sides of the unit for adequate air flow across
the condenser. Failure to allow adequate clearance
can reduce the equipment’s performance and cause
permanent damage to the compressor.

Do not allow the drape cloth to cover the side panel
louvers. This may limit air flow to the condenser.

CAUTION: To protect the life of the
compressor, continuous “No Load” operation of
the unit should NOT exceed two hours. (“No Load”

operation of the unit means running the unit with just
the heat transfer medium in place.)

Electrical Connections

Each machine requires one power supply. The Model
20 is supplied with a cord and grounding type plug. The
wall outlet must be rated 15A minimum and properly
grounded.

In the United States, this equipment is intended to be
installed in accordance with the National Electrical
Code (NEC), ANSI/NFPA 70--1987. 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. Compliance therewith and
proper maintenance will result in an installation
essentially free from hazard!

In all other areas of the world, equipment should be
installed in accordance with the existing local codes.
Please contact your local authorities.

FOLLOW YOUR LOCAL ELECTRICAL CODES!

CAUTION: THIS EQUIPMENT MUST BE
PROPERLY GROUNDED! FAILURE TO DO SO
CAN RESULT IN SEVERE PERSONAL INJURY
FROM ELECTRICAL SHOCK!

CAUTION: Always disconnect the power

supply before servicing this equipment. Failure to

comply may result in electric shock or damage to the
equipment.

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 3mm 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.

This unit is provided with an equipotential
grounding lug that is to 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 equipments frame.

Refrigerant

In consideration of our environment, Taylor
proudly 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.

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.
