Important Safety Information

Throughout this manual, notices appear to bring your attention to situations which could result in death, serious injury, or damage to the unit.

WARNING Indicates a hazardous situation which could result in death or

serious injury.

CAUTION Indicates a situation which could result in damage to the unit.

IMPORTANT Indicates important information about the use and care of the

unit.

WARNING

This unit should be destined only to the use for which it has been expressly conceived. Any other use should be considered improper and therefore dangerous. The manufacturer cannot be held responsible for injury or damage resulting from improper, incorrect, and unreasonable use.

To reduce the risk of death, electric shock, serious injury, or re, follow basic precautions including the following:

• Make sure the power switch is in the "OFF" position before making any electrical connections, plugging in, or unplugging the unit to reduce the risk of electric shock.

• Electrical connection must meet national, state, and local electrical code requirements. Failure to meet these code requirements could result in death, electric shock, serious injury, re, or severe damage to equipment.

• This unit requires an independent power supply. See the nameplate for proper voltage and breaker/fuse size. Failure to use a proper breaker or fuse can result in a tripped breaker, blown fuse, or damage to existing wiring. This could lead to heat generation or re.

• THIS UNIT MUST BE GROUNDED. Failure to properly ground this unit could result in death or serious injury. Corded Units: Corded units are equipped with a 3-prong grounding plug to reduce the risk of potential shock hazards. It must be plugged into a properly grounded, independent 3-prong wall outlet. If the outlet is a 2-prong outlet, it is your personal responsibility to have a qualied electrician replace it with a properly grounded, independent 3-prong wall outlet. Do not remove the ground prong from the power cord and do not use an adapter plug.

• Do not use an extension cord.

• Do not use a unit with a damaged power cord. The power cord should not be altered, jerked, bundled, weighed down, pinched, or tangled. Such actions could result in electric shock or re. To unplug the unit, be sure to pull the plug, not the cord, and do not jerk the cord.

• To reduce the risk of electric shock, do not touch the plug or power switch with damp hands.

• This unit should be disassembled or repaired only by qualied service personnel to reduce the risk of electric shock, injury, or re.

• Do not make any alterations to the unit. Alterations could result in electric shock, injury, re, or damage to the unit.

I. Installation Instructions

WARNING

1. This unit must be installed in accordance with all applicable national, state, and local regulations.

2. Unit is heavy. Use care when lifting or positioning. Work in pairs when needed to prevent injury or damage. Do not tilt the unit more than 45°.

A. Location

WARNING

This unit is not intended for outdoor use. Normal operating ambient temperature should be within 45°F to 100°F (7°C to 38°C). Operation of the unit, for extended periods, outside of this normal temperature range may affect unit performance.

For best operating results:

• The unit should not be located next to ovens, grills, or other high heat producing equipment.

• The location should provide a rm and level foundation for the unit.

• The unit should not be located in a corrosive environment.

• The unit should be a minimum of 4" (11 cm) from side walls. More clearance may be necessary depending on the door combination of the unit.

• A minimum of 10" (25 cm) overhead clearance should be provided for proper ventilation.

B. Checks Before Installation

WARNING

Refer to the nameplate for electrical specications. The nameplate is located on the right side wall of the cabinet interior. For more electrical connection details, see "I.D. Electrical Connection." We reserve the right to make specication and design changes without prior notice.

• Visually inspect the exterior of the shipping package and immediately report any damage to the carrier. Upon opening the package, any concealed damage should also be immediately reported to the carrier.

• Remove the shipping carton, tape, and packing material. Also remove the protective plastic lm from both the exterior panels and the interior door panel. If the unit is exposed to the sun or to heat, remove the lm after the unit cools.

• Remove all accessory containers before discarding the packing materials. Dispose of all packing materials in a proper and environmentally responsible manner.

• Check for missing or damaged accessories.

C. Setup

1. Remove the Unit from the Pallet

1) Move as close to the nal location as possible.

2) Remove the 2 bolts securing the unit to the pallet, then remove the unit from the pallet. Block the unit securely at a height of 8" (20 cm) off the oor. Do not lay the unit down.

3) Attach the adjustable legs or casters to the bottom of the unit. Locking casters should be attached to the front of the unit.

2. Optional Overow Pan Installation (if applicable)

Optional overow pan kits are available for the unlikely event that water cannot evaporate from the condensate pan at a high enough rate.

a) Reach-In Optional Overow Pan (HS-3521)

3. RFH1-SSB-HS Lower Condensate Pan Installation

The lower condensate pan collects condensate water from the evaporators of both the refrigerator and freezer. When the lower condensate pan is full, the oat switch activates the condensate pump. Condensate water is pumped into the upper condensate pan for evaporation.

WARNING

Verify that power to the unit is disconnected before installing the lower condensate pan.

1) Remove the nylon tie securing the oat switch assembly to the rear cover. Pull the oat switch assembly down below the rear cover. See Fig. 3.

2) Rotate the oat switch assembly 180° degrees. Using 1 of the screws provided, attach the oat switch assembly to the condensate pan. See Fig. 4.

3) Using the remaining 2 screws provided, mount the lower condensate pan to the rear of the unit. See Fig. 5. CAUTION! Conrm that the vinyl hose is even with the bottom of the oat switch before attaching the condensate pan to the unit.

4) Plug the unit in.
