Installation

DANGER

Installation must comply with all applicable fire and health codes in your jurisdiction.

DANGER

Use appropriate safety equipment during installation and servicing.

Warning

Do not damage the refrigeration circuit when installing, maintaining or servicing the unit.

Location

Warning

This equipment must be positioned so that the plug is accessible unless other means for disconnection from the power supply (e.g., circuit breaker or disconnect switch) is provided.

Warning

Adequate means must be provided to limit the movement of this appliance without depending on or transmitting stress to the electrical conduit or gas lines.

The location selected for the equipment must meet the following criteria. If any of these criteria are not met, select another location.

• Units are intended for indoor use only.

• Unit is designed to maintain 36°F - 40°F at 80°F ambient room temperature (2°C - 4°C at 27°C) in 55% or lower relative humidity.

• The location MUST be level, stable and capable of supporting the weight of the equipment.

• The location MUST be free from and clear of combustible materials.

• Equipment MUST be level both front to back and side to side.

• Position the equipment so it will not tip or slide.

• Proper air supply for ventilation is REQUIRED AND CRITICAL for safe and efficient operation. Refer to Clearance Requirements chart on page 7.

• Do not obstruct the flow of ventilation air. Make sure the air vents of the equipment are not blocked.

• Do not install the equipment directly over a drain. Steam rising up out of the drain will adversely affect operation, air circulation, and damage electrical / electronic components.

Weight of Equipment

Warning

To avoid instability the installation area must be capable of supporting the combined weight of the equipment and product. Additionally the equipment must be level side to side and front to back.

Electrical Service

DANGER

Check all wiring connections, including factory terminals, before operation. Connections can become loose during shipment and installation.

Warning

This appliance must be grounded and all field wiring must conform to all applicable local and national codes. Refer to rating plate for proper voltage. It is the responsibility of the end user to provide the disconnect means to satisfy the authority having jurisdiction.

VOLTAGE

All electrical work, including wire routing and grounding, must conform to local, state and national electrical codes.

The following precautions must be observed:

• The equipment must be grounded.

• A separate fuse/circuit breaker must be provided for each unit.

• Check all green ground screws, cables and wire connections to verify they are tight before start-up.

FUSE/CIRCUIT BREAKER

A separate fuse/circuit breaker must be provided for each unit.

GROUND FAULT CIRCUIT INTERRUPTER

Ground Fault Circuit Interrupter (GFCI/GFI) protection is a system that shuts down the electric circuit (opens it) when it senses an unexpected loss of power, presumably to ground. Manitowoc does not recommend the use of GFCI/GFI circuit protection to energize our equipment. If code requires the use of a GFCI/GFI then you must follow the local code. The circuit must be dedicated, sized properly and there must be a panel GFCI/GFI breaker. We do not recommend the use of GFCI/GFI outlets to energize our equipment as they are known for more intermittent nuisance trips than panel breakers.
