Outdoor Equipment; Routine Inspection; Installation; Rating Verification - Toshiba JK 720 Instruction Manual

Basic Installation and Operation Guide
during building construction. An indoor controller that is to be stored outdoors should be securely covered for
protection from weather conditions and dirt. Temporary electrical heating should be installed to prevent
condensation. Approximately 150 watts per enclosure is usually adequate.
NOTE: All loose packing or flammable materials should be removed before energizing space heaters.

Outdoor Equipment

An un-energized controller designed for outdoor installation (e.g. Type 3R) should be kept dry internally by installing
electrical heating or by energizing provided space heaters. All openings, either used or unused, should be covered
or sealed to prevent the entry of rain, vermin, insects, etc.

Routine Inspection

Routine scheduled inspection should be established if storage for an extended period is anticipated. This is to check
for condensation, corrosion, vermin, and adequacy of space heating. Prior to inspection, the equipment should be
carefully examined for evidence of physical damage, corrosion, or other deterioration.
WARNING

INSTALLATION

Rating Verification - Prior To Installation
The maximum fault capability of the power system at the point of installation should be verified and must not exceed
the short-circuit rating of the controller (see RATINGS section). All system accessories, such as surge suppressers,
lightning arresters, etc., should be checked to verify their ratings capacity.
DANGER
Do not exceed the ratings specified on the controller nameplate or system accessories.

Location

Overhead should be checked for plumbing condensation, sprinklers, or similar possible sources of trouble. A clearance
of 1/2 inch should be provided between a wall and the rear of the controller for indoor equipment, when rear access
is not required. If rear access is required in either environment, a minimum of 30 inches should be provided. Consult
local codes in case more space is required.
A minimum of 48 inches working space should be allowed in front of the controller. This minimum should be increased
if necessary to accommodate movement around open enclosure doors to comply with applicable codes.
TOSHIBA
Do not install equipment found to have damage or deterioration that could affect
the unit performance.
