INSTRUCTIONS FOR INSTALLING ELECTRICAL RECEPTACLE
FOR 43/44-UDGF FREEZERS
Important: Installation must be completed by a certified electrician and must be in accordance to the
applicable national and local electrical codes and regulations.
WARNING: DO NOT INSTALL THESE FREEZERS ON THREE-PHASE POWER SUPPLY
Parts supplied in this kit:
- Receptacle, NEMA L14-20R; qty: 1
- Receptacle cover; qty: 1
- Receptacle screws, 7/8” long; qty: 2
- Receptacle cover screw, 1/2" long; qty: 2
43-UDGF and 44-UDGF freezers require 115/208-230VAC/60Hz, single phase, 4 wire (2X hot legs, 1X neutral,
and 1X ground), electrical circuit with NEMA L14-20R receptacle. Additionally, this freezer must be installed on a
dedicated circuit protected with a 20AMP, 2-pole breaker. No other electrical loads are allowed on the same
circuit. NEMA L14-20R receptacle is shown in Figure 1.
Figure 1: NEMA L14-20R Receptacle
If such receptacle already exists at the freezer installation location, proceed to Circumstance 1: Existing Receptacle
Inspection. If it does not exist, proceed to Circumstance 2: New Circuit and Receptacle Installation.
Circumstance 1: Existing Receptacle Inspection
Set your voltmeter to VAC scale and measure the voltage between the two hot legs “A” and “B” (see Figure 1) on
the receptacle. The measured voltage should be in the range of 208VAC to 240VAC.
Next, measure the voltage between each hot leg and the neutral slot. The measured voltage should be in the range
115VAC to 120VAC. If the measured voltages are within the above mentioned specifications and there is no other
electrical load on the same circuit, then check the size and type of the circuit protector – it must be a 20AMP, 2pole breaker. If all above mentioned is correct, the installation is proper and it is safe to plug in the freezer into the
existing receptacle. There is no need to install this kit, and the kit can be discarded. If the measured voltages or the
circuit protector are outside of the specified ranges, proceed with the standard electrical troubleshooting procedures
(check wire sizes, circuit panel and breakers, other loads on the same circuit, etc.)

Circumstance 2: New Circuit and Receptacle Installation
Install a new electrical circuit by installing four electrical wires from the freezer installation location to the nearest
available breaker panel. Select appropriate wire size for a 20AMP circuit at 250VAC in accordance to the
applicable national and local electrical codes and regulations. Install a standard electrical receptacle box (not
supplied in this kit), then connect the receptacle terminals from this kit to the four wires as follows (see Figure 2):
- The two hot leg wires connect to the two brass screws, which are also marked as X and Y.
- The neutral wire connects to the white screw, which is also marked as W.
- The grounding wire connects to the green screw, which is also marked as G.
Then, install the receptacle cover supplied in this kit.
Figure 2: Receptacle terminals and markings
At the electrical panel end, connect the four wires to the spare breakers slots and install a 20AMP, 2-pole breaker
for circuit protection.
Energize the circuit and using your voltmeter check that following voltages are available at the receptacle:
- The voltage between the two hot legs “A” and “B” (see Figure 1) should be in the range of 208VAC to
240VAC
- The voltage between each of the two hot legs and the neutral slot should be 115VAC to 120VAC.
If the measured voltages are within the above mentioned specifications, the installation is proper and it is safe to
plug in the freezer.
