NEMA 4X RAINTIGHT

THERMOSTAT

Installation and Operating

Instructions

To prevent overheating or re, 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 re.

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 specications 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 re and/or explosion, do not use in potentially

ammable or explosive atmospheres.

WARNING

Installation must be made by a trained, qualied 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 ttings 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.
