GREYSTONE TLGLF24X01 Glass Low Limit Thermostat Instruction Manual
Glass Low Limit Thermostat
TLGL Series - Installation Instructions
INTRODUCTION
The low limit glass thermostat incorporates
a
precision thermistor
temperature sensor and provides a Form C relay output (NO/NC) with an
adjustable setpoint. The sensor is encapsulated in a 31.75mm L x 9.525mm W
x 9.525mm H (1.25" x 0.375" x 0.375") Aluminum probe. Standard wire length
is 1.5 m (5'). All probes are constructed to provide excellent heat transfer, fast
response and are potted to resist moisture penetration.
BEFORE INSTALLATION
Read these instructions carefully before installing and commissioning
the temperature sensor. Failure to follow these instructions may result in
product damage. Do not use in an explosive or hazardous environment,
with combustible or flammable gases, as a safety or emergency stop
device or in any other application where failure of the product could
result in personal injury. Do not exceed the device ratings.
MOUNTING
The glass thermostat installs directly onto any window where the enclosure can be mounted nearby. Select a suitable location on an exterior
window where both the probe and the enclosure can be mounted. On one side of the probe apply epoxy compound and press firmly against
the glass. See Figure 1. Use whatever means available (electrical tape will do) to secure the probe to the window while the epoxy sets.
Unroll the sensing cable probe, being careful not to kink the wire. Secure the enclosure to the wall with two #10 x 25 mm (1”) self tapping screws
(not provided). Tighten screws until the enclosure is tight against the wall and ensure that there is no movement of the enclosure as shown in
Figure 1.
The enclosure has a hinged cover with a latch. Open the cover by pulling slightly on the latch on the right side of the enclosure, at the same time
pulling on the cover, as illustrated in Figure 2.
Figure 1
A 1/2" NPT threaded connection hole is provided in the bottom of the enclosure. Screw
the EMT connector or cable gland connector in until tight. See Figure 3. It is recommended
that weatherproof conduit or cable gland fittings be used. An optional 1/2" NPT to M16
thread adapter and cable gland fitting is available.
Make wire connections as per the“Wiring”illustrations on Page 2.
Swing door closed until securely latched. For added security, two screws are provided
that may be installed in the integrated screw tabs. See Figure 4.
