RECEIVING YOUR NEW MODEL
Congratulations on your purchase of Continental Refrigerator
superior foodservice equipment! When your shipment arrives,
thoroughly examine the packaging for any punctures, dents, or
signs of rough handling. It is in your best interest to partially
remove or open the shipping container in order to examine
the contents for any missing accessories or concealed damage which may have occurred during shipment. If the cabinet
is damaged, it must be noted on the carrier’s delivery slip or
bill of lading and Freight Claim must be filed with the shipping company. FREIGHT DAMAGE IS NOT COVERED UNDER
WARRANTY.
UNCRATING YOUR NEW MODEL
The protective packaging should remain on your cabinet to
avoid dents or scratches while transporting it to the actual setup location. All shelving, accessories and legs or casters are
carefully packaged and secured inside your cabinet to prevent
damage. All doors are locked and the keys are conveniently
attached to the door handle. After moving your unit to its final
location, split the outer plastic wrap vertically, along one of
the corners of the cabinet. Remove the plastic and the protective corner guards and any accessories or boxes on the skid.
Dispose of all packaging materials properly.
GENERAL INFORMATION AND
IMPORTANT OPERATING FACTS
This manual has been compiled to aid in the installation, operation and maintenance of your new equipment. Please take the
time to read it and familiarize yourself with your equipment and
its operation, to enjoy optimum performance.
Continental Refrigerator offers a variety of accessories for your
model (see “Optional Accessories” section towards the back of
this manual or contact your dealer for more information).
SERIAL DATA TAG
A serialized data tag is permanently attached to the inside righthand wall of your unit. (see Figure 1). In addition to identifying
the specific product, this label provides important information
regarding electrical requirements and refrigeration charge, as
well as agency listings and factory contacts.
FIGURE 1: Data Tag
Four (4) bolts secure the cabinet to the wooden skid. The bolts
are located at each end on the underside of the skid. In order to
remove these bolts, tilt the cabinet backwards and place wooden blocks at each end in order to hold it in its tilted position.
Using a ¾” socket or open end wrench, remove the bolts and
carefully slide the cabinet off of the skid. If caster support plates
are to be installed, save the bolts and washers (see “Mounting
Caster Support Plates” under “Optional Accessories”). After
skid removal, the cabinet should never be moved without dollies
or rollers to avoid damage to the cabinet bottom or floor.
IMPORTANT NOTE: Do not under any circumstances, lay
your new model on its front or sides. For a brief period
of time, you may lay the cabinet on its back, but only
when it’s properly blocked so as not to crush the back
or end panels and also to allow provision for your hands,
in order to set it in its upright position without damaging
the cabinet. Do not plug in and operate model for at
least three (3) hours after cabinet is set upright from
being on its back as this can damage the compressor.
IMPORTANT NOTE: The model and serial number should
be noted on the front cover of this manual, in the spaces
provided. If parts or service are ever needed for your unit,
this information will be required to verify warranty status
and to properly identify any parts that may be needed.

All cabinets must be given sufficient time to reach normal
operating temperature before placing any food inside cabinet
or pans (if equipped). For refrigerators, approximately 1 hour
of operation is required to lower the cabinet and pan temperature to 40°F (4°C). Freezers require approximately 2 hours of
operation to lower the cabinet temperature to 0°F (-18°C) (see
“Operation” section for further information).
Prior to factory shipping, all products are performance-run
tested for a minimum of 12 hours providing a highly sophisticated temperature recording exclusive to each individual
cabinet. This recording is supplied within this manual packet. A
final evaluation, including analysis of cabinet performance, leak
check, vibration, noise level and visual examination is made by
a qualified quality control team to assure a superior product.
The carrier signs to this effect when they accept the product for
shipping. To insure the maximum in safety and sanitation, all
models are listed under the applicable standards of Underwriters
Laboratories and the National Sanitation Foundation.
MODEL COMPONENTS
FIGURE 2: Standard Reach-In Refrigerator or Freezer
Standard Reach-In refrigerators and freezers have an internal
evaporator coil located behind the fan panel on the inside ceiling of the refrigerated compartment (see Figure 2). Designer
Line Reach-In, as well as all Pass-Thru, Roll-In and Roll-Thru
refrigerators and freezers have an insulated housing located on
top of the cabinet, that contains the evaporator coil, out of the
refrigerated storage area (see Figure 2A & 2B).
All warmers have an insulated housing located on top of the
unit, that contains a blower fan to circulate warm air inside the
cabinet (see Figure 2C). On most models, the high-wattage,
finned electric heating elements are located inside the cabinet,
at the bottom of the interior side walls. On single-section Roll-In
and Roll-Thru models, the heating elements are located in the
housing on top of the unit, to optimize space for carts inside
the cabinet.

Before moving the cabinet to its final point of installation, measure all doorways or passages to assure clearance. If additional
clearance is needed, you can remove the cabinet doors and grill
(see “Door Removal and Adjustment” and “Grill Removal”).
VENTILATION
The final location site of your air cooled refrigerator or freezer
must provide a large quantity of cool, clean air. All refrigeration
systems operate most efficiently and trouble-free with cool,
dry air circulation. Avoid locations near heat and moisture
generating equipment including ovens, cooking ranges, fryers,
dishwashers, steam kettles, etc., or in direct sunlight (where
temperatures can exceed 100°F). Do not select a location in an
unheated room or area where temperatures may drop below
55°F. Air supply to the condensing unit is equally important.
Restricting the air places an excessive heat load on the condensing unit and adversely affects its operation.
INSTALLATION AND LOCATION
For optimum performance, all models should be installed on
casters or legs (see “Installing Casters” or Installing Legs”)
with a minimum 12” above the grill and 3” on each side and
back of cabinet (see Figure 3). This spacing will provide sufficient room for proper air circulation and clearance to access
components for cleaning and maintenance. If any of the these
conditions can not be met, the installer should provide special
venting or air ducts.
IMPORTANT NOTE: To assure maximum operating efficiency, your new cabinet should be located where an
unrestricted air supply can circulate above and behind the
cabinet. Do not at any time obstruct the grill area in the
front of the cabinet in any way, and never place or store
anything on top of the cabinet machine compartment.
These rules are essential for maximum cooling capacity
and long life of refrigeration parts.

INSTALLING CASTERS AND LEVELING
If your new unit is supplied with swivel casters, they will be
packed in the accessory box that came with your cabinet.
Casters should be installed only when the cabinet is close to
its final installation site. To install casters on your new model,
place wooden blocks along the back, at each end. Tilt the cabinet back, using the wood blocks to help hold the cabinet in its
tilted position. Locate the large threaded holes on the bottom
of the cabinet and screw the threaded caster studs into the
mounting holes, closest to the front of the unit. Repeat this
procedure by tilting the cabinet in the opposite direction and
installing the remaining casters. Make sure the casters are
tightened extremely well (see Figure 4 & 4A). If the casters are
not installed tightly, the cabinet will be unstable and may sway
or rock, which can damage the cabinet.
If the height of a caster needs to be raised, shims must be
installed under the casters which need leveling. Extra large
washers, available at most hardware or furniture stores, can
be used to shim casters, or contact the factory for caster
shims. For maximum stability under extreme conditions, caster
plate assemblies are available from the factory (see “Optional
Accessories” section of this manual).
FLOOR LOADS
The floor at the final location site must be level, free of vibration
and strong enough to support the total combined weights of
your new model plus the maximum product load which might
be placed into it. Keep in mind that all the weight is concentrated
at the caster or leg locations. To estimate the possible product
weight, assume that each cubic foot of storage space weighs
approximately 35 pounds. Multiply 35 pounds by the amount of
cubic feet in the cabinet to obtain the product load weight.
For example, a 20 cubic foot refrigerator can hold approximately
700 pounds of product (35 x 20). Assuming the cabinet itself
weighs 300 pounds, the total combined weight of cabinet and
product is approximately 1000 pounds. Therefore, the floor in
this example must be able to support up to 1000 pounds.
Do not attempt to level casters by unscrewing them
from the cabinet and leaving them loose, as this will
cause damage to the cabinet and leg hole threads,
voiding all warranties.

INSTALLING LEGS AND LEVELING
If your new unit is supplied with adjustable legs, they will be
packed in the accessory carton in the cabinet. Your cabinet will
have either four (4) or (6) threaded mounting holes on the bottom of the cabinet (see Figure 5). In order to install the legs,
carefully tip the cabinet back, adding four (4) 2” wood blocks
underneath, and simply screw the threaded leg studs into the
case bottom front leg holes. Repeat this procedure by tilting
the cabinet in the opposite direction and install the remaining
legs. Make sure the legs are tightened extremely well or the
entire model will sway or rock with each opening or closing of
the doors, possibly causing damage to the case bottom. This
procedure should be performed close to the final installation
site and allow access to the rear of the cabinet.
To assure your cabinet is level, all legs are equipped with bullettype leveling bolts. These bolts can be turned by hand or by
wrench, clockwise or counterclockwise to level the cabinet.
FIGURE 5: Leg Installation
MOUNTING AND LEVELING
Roll-In and Roll-Thru Models
Roll-In and Roll-Thru models are designed to be mounted
directly on the floor without legs or casters (see Figure 6).
IMPORTANT: The floor where any roll-in or roll-thru unit
is to be located must be level and flat. If it is not, it must
be made level prior to attempting to install the cabinet.
THIS IS CRITICAL FOR ROLL-THRU MODELS.
After removing your Roll-In or Roll-Thru from the skid, you may
carefully slide it into position. To avoid damaging or racking
your cabinet, carefully push on the lower half of the case end.
Once the cabinet is positioned in its final location, check that it
is level and plumb in all directions. Using a carpenter’s level, at
least 3’ long, check the floor of the cabinet horizontally in each
direction. Also use the level to check the exterior sides and back
of the cabinet vertically. Using a carpenters square, check each
corner of the door openings, to insure they are at 90° angles. If
necessary, insert shims under the cabinet to make adjustments.
Recheck with the level and square, and carefully push on the
sides of the cabinet to make sure it is stable. The base of the
cabinet should be sealed to the floor around its entire perimeter
with NSF approved sealant, to meet sanitation requirements.
Your Roll-In and Roll-Thru model comes with one cart ramp
per door opening (see Figure 6). To install the ramp(s), simply
open the cabinet door and position the ramp with the wide edge
towards the front of the cabinet floor. Set the ramp so the slots
along the wide edge sit over the screws along the front of the
cabinet floor and push down to engage. If the door wiper rubs
along the ramp, to the extreme where the door will not selfclose, you will need to adjust the door (see “Door Removal
and Adjustment” section) and/or level the cabinet as explained
above.

result in the loss of all food stored in the cabinet.
Defrost water will fail to drain properly and will 4.
overflow the evaporator coil drain pan and into the
cabinet of both refrigerator and freezer models.
CONDENSATE REMOVAL
Interior Coil Models
No floor drains or plumbing connections are required since all
models use an automatic condensate water evaporating system. Standard Reach-In models feature an evaporator housing,
located on the inside ceiling of the refrigerated storage area
(see Figure 2) and an electric condensate vaporizer pan with a
mounting bracket packed in the accessory carton.
To install the vaporizer, remove the pan, power cord, cord clamp
and screw from the carton (see Figure 7). Connect the cord
to the vaporizer as shown. Route the cord around the outside
of the pan and through the clamp as illustrated. Secure the
cord and clip to the pan by fastening the mounting screw into
the threaded hole on the side of the vaporizer. Remove the (2)
mounting screws from the back of the cabinet. Position the
bracket as shown and place the vaporizer in the bracket, making
sure the power cord is routed as illustrated. Attach the bracket
to the cabinet with the screws. Using a sharp knife or scissors,
cut the drain tube so the end is about 2” below the bottom of the
cabinet. Place the end of the drain tube in the pan, making sure
the tube is not blocked, kinked, or sitting on the bottom of the
vaporizer pan. Check that the water level switch is operating correctly by lightly pressing down on the top of the vaporizer, at the
end where the cord is attached. You will hear a “click” as pressure is applied and another “click” when pressure is removed. If
you do not hear the switch “click”, ensure the vaporizer is seated
in the bracket correctly and the cord is routed correctly and
secured in the clamp. Plug the power cord into the receptacle
labeled “VAPORIZER” on top of the cabinet.
IMPORTANT: It is extremely important that the water
level switch operates correctly, that the vaporizer is
plugged into the correct receptacle labeled “VAPORIZER”
and the compressor is securely plugged into the receptacle labeled “CONDENSING UNIT”. Improper installation
may cause your cabinet and/or vaporizer to not operate
correctly. This can result in water overflowing the pan and
onto the floor.

Top Mount Coil Housing Models
Designer Line Reach-Ins, as well as all Pass-Thrus, Roll-Ins and
Roll-Thrus feature an insulated evaporator housing, located on
the top of the cabinet, out of the food zone (see Figure 2A &
2B). These models utilize a unique self-contained hot air evaporating system to automatically eliminate condensate water.
No floor drains or plumbing connections are required and the
system is completely self-contained, so no further assembly
or maintenance is required. In some adverse conditions such
as high ambient temperature, high humidity, extremely heavy
usage, frequent loading for prolonged periods of time, or heavy
pan loading, the amount of condensate water generated could
overflow the pan. If this occurs, the plastic drain tube from the
cabinet can be diverted directly to a floor drain, bypassing the
condensate pan. Alternatively, an optional electric condensate
vaporizer may be purchased as an accessory. An electric condensate vaporizer is also supplied with all remote reach-in and
pass-thru models. To install the optional condensate vaporizer,
follow the steps for “Interior Coil Models” in the previous
section. Remote roll-in and roll-thru models are supplied with
an electric heater in the condensate pan on top of the cabinet,
which must be connected to a power supply by the installer.
DOOR REMOVAL AND ADJUSTMENT
During installation, it may become necessary to remove the
cabinet doors to facilitate passage through narrow doorways or
hallways. To remove a door, carefully pry off all hinge covers
using a sharp tool or knife (see Figure 8A). Swing the door to
the open-door position (90°) and carefully lift the door upward,
so the hinge pin (attached to the door) clears the hinge body
(mounted to the cabinet). If it is necessary to remove the hinge
bodies from the cabinet face, use caution when loosening the
top hinge bodies, as they cover the light switch plunger. To reinstall the door, reverse the above procedure. (For glass doors,
see “Optional Accessories”).
All doors are aligned at the factory, however vibration during
transit may cause doors to shift and adjustment may be necessary. If the door(s) require realignment, carefully pry off all hinge
covers (see Figure 8A) using a sharp putty knife or flat-blade
screwdriver. Loosen the screws securing the hinge bodies to the
face of the cabinet and slide the door into alignment. Hold the
door firmly in place and tighten all screws securely.
If the door gasket(s) do not seal properly to the cabinet face
and there are gaps between the gasket and the face on the hinge
edge, adjust the door by removing the hinge covers (see Figure
8A) and loosening the adjustment screws securing the hinge pin
to the door. Push the face of the door towards the face of the
cabinet, so the gasket firmly contacts the cabinet. If the door is
pressed too tight against the cabinet, the gasket will pinch along
the hinge side and the door will not close and seal properly. Hold
the door firmly in place and tighten all screws securely. Open
and close the door several times to check that the gasket seals
properly all the way around the door. Re-adjust if necessary and
make sure all screws are tight. Replace all hinge covers.

REMOVAL AND REPLACEMENT
OF HINGE MECHANISM
Before attempting any work on your refrigerator or freezer, it is
strongly recommended that all contents be removed and stored
in a walk-in or other refrigerated space. Disconnect power by
unplugging the cabinet, or switching off circuit breaker. The
following tools are needed to remove the hinge: straight-blade
screwdriver and philips screwdriver with large (#3) tip.
To remove a hinge, open the door approximately 90° and lift
it off the hinge bodies. Remove the hinge pin and adjustment
plate from the door (see Figure 8A) by loosening the adjustment
screws. Remove the hinge body from the face of the cabinet by
loosening the (3) flat-head machine screws. To remove the lock
keeper from the cabinet, remove the 2 screws on the inside edge
of the keeper (see Figure 8A) and slide it off the base. If the
white, nylon cam needs to be removed from the hinge body, a
straight blade screwdriver may be used to carefully pry the cam
out of the body. Be careful not to damage the cam, as the nylon
material is soft. Reverse the cam by rotating it 180° and pressing
it firmly back in place.
RE-HINGING DOORS (Reach-Ins)
Single section, solid long door models are rehingeable in the
field, without the need to modify the cabinet. A scraper or
flat-blade screwdriver, a philips screwdriver and wire crimpers
will be needed. Before attempting to rehinge your unit, unload
all contents and store in walk-in or other refrigerated space.
Disconnect power to the cabinet.

OPERATIONS MANUAL
Open the door approximately 90° and lift it off the hinges.
Remove the hinge pin assemblies from the door (see Figure
8A). Reverse each pin by rotating it 180° and reattaching it to the
door. Remove the hinge bodies and lock keeper(s) from the front
of the cabinet. Remove the white, nylon cam from the hinge
body. (A straight blade screwdriver may be used to carefully
pry the cam out of the body, without damaging it.) Reverse the
cam by rotating it 180° and pressing it firmly back in. Remove
the light switch from the front of the cabinet and pull the switch
out of the hole.
Remove the screws and plug button from the face of the cabinet, on the opposite side hinge locations. The wires for the light
switch will be coiled up in the insulation, behind the plug button.
Carefully pull the wires out and install female connectors for the
light switch. Remove the old light switch from behind the top
hinge and remove the wire connectors.
REACH-INS & ROLL-INS
Cap each lead on the brown lamp cord separately, push the
wires into the insulation and insert the plug button into the hole.
Remove the cover from the control box, on top of the cabinet.
There will be a black lamp cord, with a tag identifying it as the
light switch wire. Install (2) female wire connectors on the black
lamp cord. There will be (2) brown lamp cord leads on the terminal block. Disconnect them and replace with the wires from
the black lamp cord. Cut off the old leads on the brown ripcord
and secure them out of the way, so they will not contact any live
wiring. Check that all wires are properly connected and secured.
Replace the control box cover. Remount the hinges and actuator
button for the switch to the face of the cabinet. Remount lock
keeper and door. Reconnect power to the cabinet.
NOTE: All wiring and connections should only be made by
a qualified electrician.
REMOVING GRILL
To remove the grill, loosen, but do not remove, the (4) mounting
screws located on the back side of the grill at the ends. Simply
lift grill up off of its mounting screws and out. To replace the
grill, line up the grill mounting screws with the keyhole slots
located on the cabinet body, push in and down on the grill.
IMPORTANT NOTE: The wiring to the anti-condensate
switch and the thin copper tubing or cable for the thermometer are provided with leads long enough to allow
the grill to be laid across the top of the cabinet after it
has been removed. Take care not to damage the wires or
copper tubing when handling the grill.
If you need to completely remove the grill from the cabinet,
disconnect the power supply to the cabinet. Remove the wires
on the back of the anti-condensate switch on the grill. Locate the
thermometer sensing bulb and cover, located inside the cabinet.
On Standard Reach-In models, the thermometer bulb cover
is under a small cover channel on the interior top left corner
towards the front of the cabinet. On Designer Line, Pass-Thru,
Roll-In and Roll-Thru models, the thermometer bulb is located
on the interior top, under the air duct. Remove the cover, carefully grasp the bulb and push it back through the cabinet hole.
The thermometer bulb and grill can now be removed from the
cabinet. When reinstalling the thermometer bulb, be sure to
replace the sealant putty around the hole into the insulation.
Reattach the leads for the anti-condensate heater switch and
reconnect the cabinet’s power supply.

Prior to start-up and before placing any product inside of your
new model, the interior of the cabinet should be thoroughly
cleaned. Washing with a mild soap and warm water solution
is recommended for cleaning the aluminum and stainless steel
surfaces of your cabinet. This should be followed by cleaning
with a baking soda solution (three (3) tablespoons of baking
soda to each quart of warm water). Rinse thoroughly with clear
water and dry with a clean, soft cloth.
IMPORTANT NOTE: Never use harsh detergents, cleaners, scouring powders or chemicals when cleaning your
model. Failure to dry the interior surfaces after cleaning
may result in a streaking or staining of the metal.
Complete cleaning procedures and precautions are listed in the
(“Periodic Cleaning Procedure” under “Maintenance”).
START-UP PROCEDURE
ELECTRICAL CONNECTIONS
To insure proper operation, your new model must be connected
to an individual circuit that can supply the full voltage as stated
on the cabinet serial data plate. For correct voltage, power draw,
and wire accommodations, check the data on the serial data plate
located on the inner right wall of your new model. Verify that this
information exactly matches the electrical characteristics at the
installation location. An electrical wiring diagram, located on the
inside compressor compartment rear, next to the electrical console box, should also be consulted during connection. For reference, a copy of each electrical wiring diagram is located towards
the back of this manual (see “Wiring Diagrams” section).
Refrigeration compressors are designed to operate within
+/-10% of the rated voltage indicated on the cabinet serial
plate. Excessively high or low supply power can burnout the
compressor. This can be easily detected and will void the factory warranty. Full voltage at the correct rating, on a separate,
designated circuit, not affected by the operation of other electrical appliances, must be available to the refrigeration unit at all
times. Extension cords should never be used on commercial
equipment, as they can overheat and/or result in low voltage.

REACH-INS & ROLL-INS
GFI/GFCI RECEPTACLES
Building codes in some areas may require certain 115 volt
receptacles to be protected by a Ground-Fault Circuit Interrupter
(GFCI or GFI). These devices are not recommended for most
commercial refrigerators and freezers, since nuisance trips can
occur (typically due to moisture) causing temporary loss of
power. This may result in intermittently high storage temperatures and potentially unsafe food product. If you decide to connect your equipment to a GFCI protected receptacle, a properly
sized, commercial grade circuit breaker should be used on a
separate, designated power supply. Alternatively, a qualified
electrician may be able to hard wire your equipment, eliminating the need for a GFCI device. Contact Continental’s Service
Department before making any modifications to your cabinet, to
avoid loss of warranty coverage.
NOTE: GFCI DEVICES ARE NOT RECOMMENDED.
PRODUCT LOSS AND/OR PROBLEMS RESULTING FROM
NUISANCE TRIPS OR CONNECTION TO A DEFECTIVE
OR IMPROPER POWER SUPPLY, ARE NOT COVERED
UNDER WARRANTY. UNAUTHORIZED MODIFICATIONS
TO YOUR EQUIPMENT OR THE POWER CORD CAN
CAUSE AN ELECTRICAL HAZARD AND WILL VOID THE
FACTORY WARRANTY.
115/208-230 VOLT, 60 HZ, 1 PHASE CONNECTION
All 115/208-230 volt models are provided with three (3) supply wires, which exit the electrical box located in the machine
compartment rear, next to the compressor. The cabinet circuitry
is 115 volts and the condensing unit operates on 208-230 volts.
A permanently connected, 3-wire (plus ground) power supply is
required, consisting of (2) hot conductors and (1) neutral wire,
plus (1) ground wire. The supply leads must be connected to
the appropriate leads from the cabinet and the supply ground
wire must be attached to the electrical box with a ground lug
to provide proper grounding of the metal cabinet and chassis.
All wiring and connections should only be made by a qualified
electrician and must conform to all local electrical codes.
SPECIAL VOLTAGE CONNECTIONS
When models are ordered from the factory with special, optional
voltages, connections should be made as required on the electrical wiring diagram provided on the inside compressor compartment rear next to the electrical console box.
START-UP CHECKLIST
After your model has been installed, leveled, cleaned, and electrically connected in accordance with this manual, please take
the time before start-up to observe the following precautions to
assure trouble-free operation:
115 VOLT, 60 HZ, 1 PHASE CONNECTION
All 115 volt models are provided with a factory
installed, UL approved 15-amp power cord and
NEMA 5-15P plug, or a 20-amp cord with a
NEMA 5-20P plug. To insure proper operation,
this equipment must be plugged into a NEMA
compatible, grounded receptacle that can supply the full voltage and amperage stated on the
serial plate (see Figure 1).
IMPORTANT NOTE: A SEPARATE, ISOLATED, PROPERLY
SIZED POWER SUPPLY MUST BE PROVIDED. GFCI
DEVICES AND/OR EXTENSION CORDS SHOULD NOT
BE USED. PRODUCT LOSS, AS WELL AS PROBLEMS
RESULTING FROM NUISANCE TRIPS OR HIGH/LOW
VOLTAGE, ARE NOT COVERED UNDER WARRANTY.
1. Check that all exposed refrigeration lines are free of kinks.
2. Check that the condenser fan and evaporator fans are free
to rotate without any obstructions.
3. Make sure that the cabinet is properly leveled (see
“Leveling” under “Installation and Location” section).
The system should run smoothly and quietly in accordance
with generally accepted commercial standards. If any unusual
noises are heard, turn the unit off immediately and check for any
obstructions of the condenser or evaporator fans. Fan motors,
fan blades, or fan housings can be jarred out of position through
rough handling in transit or during installation.
CAUTION: IF UNIT IS UNPLUGGED OR DISCONNECTED
FOR ANY REASON, ALLOW 5-6 MINUTES BEFORE
TURNING THE UNIT BACK ON TO ALLOW THE SYSTEM
TO EQUALIZE. DISREGARDING THIS PROCEDURE
COULD CAUSE AN OVERLOAD AND PREVENT THE UNIT
FROM OPERATING.
