WATER TEMPERATURE AND AIR FLOW RATES

Following are installation guidelines:

  • Disconnect power at main panel.

  • Make certain all wiring is in accordance with all local codes.   

 

  • Ensure units are properly grounded.

  •  Heater voltage rating should be the same as supply load. 

1. The heater should be located a minimum of 4 inches off a fi nished fl oor, although, to dramatically reduce the lint and dust intake, mount up to 10 inches off the  

 

  fl oor. However, too high of placement on a wall may change the visual appearance of the product. King further recommends placement of 4 inches from any side    

  wall longer than 18 inches, and 8 inches below a ceiling or shelf that protrudes more than 6 inches. Screws or nails can be used to secure the can to the studs.    

  The wall can should take up the room of a standard 2 x 4 stud cavity. If deeper than a 2 x 4 stud wall make sure the can reveals itself outside the fi nished wall 

  by ¾". Make sure the “Up” sticker is clearly observed in the can and on the grill. 

2. Feed the power to the center of the can, with a maximum of 15 Amp circuit protection. Provide a ½" strain relief and follow all local and national electrical  

 

  codes for wire sizing and proper connection. Aluminum wire will require special connectors and preparation to the connections for a safe connection. 

3. Feed both the water lines to the upper left corner of the can. Offset 5/8" threaded copper pipe fi ttings are provided for easy hook up, in or out of the box.

4. Complete piping and bleed air out of coil for 5 minutes with system pump operating at maximum fl ow rate.

5. Copper coils are manufactured to be used with potable water and pressures up to 125 psi. Copper tubing used in the coil is Alloy 122 made to ASTM-B-75 

 specifi cations. This is the same Coper used in homes for drinking water.

6. Connect the electrical power to the motor leads selecting the speed required for the application. The white wire is the common lead, black is high speed and red is   

  low speed. Use only two leads, white and black for high speed or white and red for low speed. Connect the green groundwire to the bare groundwire.

7.  A proper thermostat per heater should be used to maintain and provide the best comfort and energy effi ciency from your King heaters. King requires the use of    

  King models HW120, HWP120, and one timer thermostat per system, the HWPT120, as they were specifi cally designed for use with the heater. King thermostat    

  models HB and HBP are also approved for use.

8. Test fan coil for motor operation and check for leaks at pipe connections.

9. Place grille on, using the 2 screws provided. Do not over tighten.
