GE RAK4157, RAK4207, RAK4307 Installation Instructions

IMPORTANT NOTES

This kit is for use with 230/208 Volt GE Zoneline
units only.
This unit must be properly grounded.
The electrical rating marked on the installed Zoneline
and power supply kit must be the same as the supply branch circuit.
problems—consult a qualified electrician.
All wiring, including installation of the receptacle,
must be in accordance with the NEC and local codes, ordinances and regulations.
This power supply kit provides for connection of
1/2trade size electrical conduit and provision for connection to a wiring system in accordance with the National Electrical Code. ANSI/NFPA No. 70-1996 or latest edition.
Use ONLY the wiring size recommended for single
outlet branch circuit.
Proper current protection is the responsibility of
the owner.

FOR 230/208 VOLT DIRECT CONNECT APPLICATIONS ONLY

IMPORTANT: Some local electrical codes and customer requirements require PTAC/PTHP units to be direct connected to building wiring.
These models must be installed using the appropriate GE power supply kit for the branch circuit amperage and the electrical resistance heater wattage desired. See the POWER CONNECTION CHART to confirm the appropriate kit.
POWER CONNECTION CHART
It is the responsibility of the installer to ensure the connection of components is done in accordance with electrical codes.
Direct connection to branch circuit wiring inside the provided junction box must be made by connecting as follows.

3. INSTALL JUNCTION BOX
Install the junction box by engaging the left tabs on the
lower right face of the unit, aligning the screw holes at the top and bottom and driving the two screws until secure. Be sure that all wire leads are inside the box and not pinched between the box and the unit. The green insulated ground wire from the unit MUST be connected to the branch circuit ground wire.
Make all wire connections by using appropriate UL-listed electrical connectors and techniques (black to black, white to white and green to green).
4.
INSTALL JUNCTION BOX COVER
1. Carefully tuck all wires and connections back inside the junction box. Be sure there are no loose connections or stray uninsulated wires exposed.
2. Place the junction box cover in place. Replace the two screws removed earlier and tighten securely.
3. Replace the Zoneline front cabinet.
2. ATTACH CONDUIT
1. Use the round knockout at the bottom of the junction box to attach conduit coming from the branch circuit. Remove the knockout, attach the conduit and bring wires into the junction box. Leave 6of wire free at the end of the conduit to allow connections to be made.
2. If a fuse and fuseholder are to be used, the knockout at the top of the box is for mounting a Buss Fuseholder. Be sure the fuse and fuseholder are of the same rating as the branch circuit. Leadwires at the fuse can be either soldered in place or attached using UL-listed 1/4female (receptacle) crimp connectors.

3. INSTALL JUNCTION BOX
Install the junction box by engaging the tab at the lower
rear, aligning the screw hole at the top and driving the one screw until secure. Be sure that all wire leads are inside the box and not pinched between the box and the unit. The green insulated ground wire from the unit MUST be connected to the branch circuit ground wire.
Make all wire connections by using appropriate UL-listed electrical connectors and techniques (black to black, white to white and green to green).

4. MAKE WIRE LEAD CONNECTIONS INSIDE THE JUNCTION BOX
1. Make all wire connections by using appropriate
UL-listed electrical connectors and techniques.
2. Connect the white and black leads of the Zoneline
power supply kit to the branch circuit Neutral and L1 leads. (The white lead of the power supply kit should be connected to neutral.) Connect the green lead of the power supply kit to the power supply and branch circuit ground.
3. Be sure that all wire leads are inside the junction box
and not pinched between the box and the unit. The green insulated ground wire from the Zoneline MUST be connected to the branch circuit ground wire.
4. Plug the 9-pin connector into the 9-pin receptacle in
the junction box.
5. Replace the junction box cover by replacing the
2 screws removed earlier.
6. Replace the case front panel by replacing the 4 front
screws and the 2 top screws. Replace the filter.
3. ATTACH CONDUIT
Use the round knockout hole at the top of the junction box to install conduit coming from the branch circuit. Install and clamp the conduit through the conduit clamp and bring wire leads into the junction box. Leave 8of wire free from the end of the conduit.
1. REMOVE THE FRONT PANEL
Remove the front case panel by removing the filter, taking out the 4 front screws, the upper 2 screws from the top of the panel and the shipping screws on each side, if present. (Discard the 2 side shipping screws, if present.)
