1.A qualified electrician must install the SMMC-3.

2.If after carefully reading these instructions you still have questions regarding installation operation or maintenance of this product, call the numbers listed for assistance.

3.Prior to installation, check the SMMC-3 Control Panel for possible shipping damage. Do not install a damaged SMMC-3 Control Panel.

4.All heating equipment, controls & associated systems must be installed in compliance with the latest editions of all applicable electrical codes and ordinances.

5.The SMMC-3 has been designed to accept only Nelson moisture and temperature sensor inputs. The risk of fire or electric shock exists if the SMMC- 3 is connected to any device other than a Nelson sensor.

6.Do not connect heating equipment directly to the SMMC-3 Control Panel. The SMMC-3 control relays provide an output to operate external contactors. Each output provides a maximum current output of 1.25A. The risk of fire or electric shock exists if the heating equipment is directly connected to the SMMC-3 Control Panel.

7.These instructions must be saved and made available to owners or users of this product and/or transferred to future owners.

8.Secure the SMMC-3 in an accessible location. The SMMC-3 Control Panel is not suitable for installation environments subject to condensing moisture or those exposed to temperature extremes.

9.Avoid shock or vibration.

INSTALLATION

 

Fig.3 Mounting: mounts to wall via three #10 screws

1. Mount the SMMC-3 securely to the wall with three

 

 

 

#10 screws, mount in an upright position in an indoor

 

 

 

location, in an area that is dry and not subject to

 

 

 

temperature extremes. See Fig. 3 for mounting

 

 

 

details.

 

 

 

 

 

 

2. Four ½” connectors have been installed on the

 

 

 

SMMC-3 Control Panel box to facilitate connection of

 

 

 

electrical conduit for input power supply wiring, and

 

 

 

contactor output wiring.

 

 

 

 

3. Remove the lower front access cover to begin

mounting screw

connecting wiring. On the back of the access cover is

 

locations

a wiring guide label.

 

 

 

 

4. Connection to the SMMC-3 is done through terminal

 

 

 

blocks. Fish the wire being connected through the

 

 

 

adjacent knock-out, and pull out approximately 12” of

 

 

 

wire. The top half of the terminal block is removable

 

 

 

for easy wiring; gently pull up on the top half to

 

 

 

remove. After connecting the wire to the top half

 

 

 

gently set it back into the base while carefully pulling

 

 

 

back excess wire through the knock-out.
