CCI Thermal Technologies TF - NEMA 4X Water-Resistant Thermostat - Manual

NEMA 4X RAINTIGHT
THERMOSTAT
Installation and Operating
Instructions
To prevent overheating or fire, use this control as an operating or
regulating thermostat. ALWAYS USE A BACKUP CONTROL OR
ALARM if a control failure could cause the controlled appliance to
overheat or could cause a fire.
Where thermostat is capable of cycling directly between heating and
cooling loads, failure to provide a load transfer switch will result in
thermostat failure.
Do not install, use or operate if product appears damaged, the
enclosure is cracked or broken or if the sensor has been bent,
crimped or is dirty.
WARNING
READ INSTRUCTIONS CAREFULLY BEFORE ATTEMPTING TO
INSTALL, OPERATE OR SERVICE THIS THERMOSTAT. Failure to
observe safety information and comply with instructions could result in
PERSONAL INJURY, DEATH AND/OR PROPERTY DAMAGE.
Retain these instructions for future reference. This product, when
installed, will be part of an engineered system whose specifications and
performance characteristics are not designed or controlled by Sunne
Controls. You must review your application and national and local codes
to assure that your installation will be functional and safe.
WARNING
Even though this thermostat is sealed, water or dust could enter through
improperly sealed wiring. A drip loop should be provided to prevent
water or other liquids from entering the thermostat housing. The cord or
conduit connections to the enclosure must be water and dust tight. The
cover must be tightened securely to compress the gasket and provide a
watertight seal. Use only screws provided. Do not over-tighten.
Maximum sensing element withstand temperature is 35°F (20°C) above
the highest temperature setting. Maximum temperature for the plastic
enclosure is 140°F (60°C).
For use in wet or humid environments or where water tightness is
required, failure to use suitable watertight connections and suitable
drip loop could allow water to enter the enclosure resulting in
thermostat failure.
Use copper wire only. Insulate or wire-nut all unused leads.
Use the grounding provisions provided for connection to the line
ground and equipment ground wire.
CAUTION
OPERATION AND CHECK-OUT
Allow one hour or necessary amount of time for the thermostat and
system to stabilize for normal operation. This thermostat is factory
calibrated and requires no correction on site.
TO CHECK OPERATION OF HEATING SYSTEMS:
• Disconnect power.
• Place the het/cool selector switch, if applicable, in the heat position.
• Adjust the thermostat set point to at least 10°F (5°C) below the
temperature of the controlled space.
• Restore power.
• Slowly adjust the thermostat knob to raise the set point. When the
set point reaches the approximate temperature of the controlled
space, the heating equipment should start.
TO CHECK OPERATION OF COOLING SYSTEMS:
• Disconnect power.
• Place the heat/cool selector switch, if applicable, in the cool position.
• Adjust the thermostat set point to at least 10°F (5°C) above the
temperature of the controlled space.
• Restore power.
• Slowly adjust the thermostat knob to lower the set point. When the
set point reaches the approximate temperature of the controlled
space, the cooling equipment should start.
APPROPRIATE APPLICATION
This thermostat has been tested by CSA and Underwriters Laboratories
Inc. (UL), meets the requirements for NEMA 4X equipment and is
suitable for use under the National Electrical Code (NEC), Article 547-4,
when used with appropriate watertight connectors (not included).
INSTALLATION
To avoid electrical shock or damage to equipment, disconnect all
power before installing or servicing.
To avoid potential fire and/or explosion, do not use in potentially
flammable or explosive atmospheres.
WARNING
Installation must be made by a trained, qualified service person in
accordance with the National Electrical Code (NEC) and all applicable
local codes and ordinances. Installation should meet all applicable
national, state and local codes. Refer to the appropriate wiring diagram
included. Locate the thermostat (Local sensing models) or sensing
bulb (remote sensing models) for optimum temperature sensing of the
controlled space. Thermostat operation will be affected by unusual heat
or cold, such as direct sunlight, near windows or doors or on outside
walls.
All fittings and materials used for the installation should be approved,
suitable and installed properly for the intended application. For water
tightness, the cord seal or conduit hub should be UL listed and be
marked 4X. The conduit hub is to be tightened onto the conduit before
installing in the enclosure.
Where applicable, remove knockout(s) by impacting near the inside
edge of the knockout to be removed. IMPORTANT: Do not impact, dent
or use the sensor for support. This will cause calibration and/or
thermostat failure.
