drawers to bear the weight of the unit when lowering.
3) Remove the protective plastic lm from the exterior and interior, including the rail cover.
If the unit has been exposed to the sun or to heat, remove the lm after the unit cools.
2. Install the Rail Condensate Pan
Slide the rail condensate pan into place on the
brackets under the front of the unit. See Fig. 1. Make
sure the pan contacts the rear stops.

3. Check the Refrigeration Circuit
1)Visuallycheckthattherefrigerantlinesdonotrubortouchotherlinesorsurfacesand
that the condenser fan blade and rail fan blades turn freely.
2) Check that the compressor is snug on all mounting pads.
4. Position the Unit and Lock the Front Casters

2) Insert the rail cover's rear pins into the rear slots on both brackets, then use the rail
cover's front pins and the notches on the brackets to place the rail cover in the open
position. You can use either set of notches. The hollow side of the rail cover should face
down. See Fig. 4.
WARNING
When the rail cover is open, make sure the rear pins on both sides of the rail
cover are securely in the rear slots and the front pins are resting securely in the
notches. Otherwise, the rail cover could close suddenly and cause injury.
3) Place rail dividers (sold separately) and empty pans (sold separately) on the rail. On
the HPR100A(-D), place the divider included with the unit as shown in Fig. 5. When
operating the rail, the entire rail must be covered by rail dividers and pans. Otherwise,
the rail will not cool properly.Usepanswithadepthofupto6"(15cm).Donotuse
damaged rail dividers or pans.
6. Prepare the Rail

D. Electrical Connection
WARNING
1. 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.
2. 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.
3. THIS UNIT MUST BE GROUNDED: This unit is equipped with a 3-prong
grounding plug to reduce the risk of potential shock hazards. It must be
plugged into a properly grounded, independent 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. Failure to follow these instructions may result in death, electric shock, or
re.
4. Do not use an extension cord.
5.Makesurethepowerswitchisinthe"OFF"positionbeforeplugginginor
unplugging the unit to reduce the risk of electric shock. The power switch is
located behind the front panel.SeeFig.8in"I.E.AccessingtheControls."
6. 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.
7. To reduce the risk of electric shock, do not touch the plug or power switch with
damp hands.
