PRODUCT REGISTRATION
CAREFULLY READ THESE INSTRUCTIONS. This manual provides instructions in how to best locate,
operate, and maintain this equipment. It is recommended to keep this manual for any future reference.
The CTRH-4 has a sanitation listing permitting the merchandising of packaged food and beverage
product. The unit must be located in an indoor environment where the ambient must be
maintained less than 75oF/65oRH.
If the equipment will be kept in storage, it is suggested to keep it in its original packing. In case you
need your equipment to be inactive for a long period of time after being used, verify that it has been
unplugged. After cleaning it thoroughly with a damp cloth, lukewarm water and neutral soap and
carefully drying it, cover it with a polyethylene film or similar waterproof material.
The following procedure is recommended for uncrating the unit:
Remove the outer package by carefully cutting the shrink wrap and removing the 4 corner posts
and top lid. Inspect for concealed damage. Immediately file a claim with the freight carrier if there is
damage. Move your unit as close to the final location as possible before removing the wooden skid.
Write down the Serial number of your new unit for future reference. The Serial Number is found on the
data plate located on the back of the unit.

PLACING AND INSTALLING EQUIPMENT
ENVIRONMENTAL CONDITIONS
THIS UNIT CANNOT BE INSTALLED IN ENVIRONMENTS WITH EXPLOSIVE GASES. THE
EQUIPMENT IS DESIGNED ONLY FOR INDOOR OPERATION.
The unit must be located in an indoor environment where the ambient is maintained less than
75oF/65%RH.
For the correct performance of the refrigerating system, it is very
important to leave at least 10 cm (4”) of free space both at the
sides and back to allow proper air circulation.
The location of the cooler must be kept away from sources of
heat and humidity including direct sunlight, toasters, ovens,
coffee warmers, other appliances condenser air discharge,
infrared heaters, or other heat generating appliances. Keep the
unit away from external doors.
The unit should be leveled prior to operation.
Leveling Legs

The power cord of this appliance is equipped with a 3-prong (grounding) plug which mates with a
standard 3-prong (grounding) NEMA 5-13R type wall outlet to minimize the possibility of electric
shock hazard from this appliance.
The use of extension cords is not permitted and will void the warranty.
Before connecting your equipment, check that the electrical data on the data plate match your
electrical output.
IMPORTANT NOTICE: PLUG THE EQUIPMENT INDEPENDENTLY TO A LOAD CENTER WITH AN
APPROPRIATE CIRCUIT BREAKER ACCORDING TO THE NAMEPLATE AMPS.
The shelves and holders have been fixed to the inside floor of the unit to prevent their loss during
transportation.
Insert the shelf brackets in the pilaster notches making sure they are at the same level such that the
shelves remain horizontal.
IMPORTANT: The products on each shelf must leave three to five centimeters of free clearance
between them and the next shelf in order to allow proper air circulation.
The CTRH-4 is not intended to be a pull down refrigerator and as such the product must be loaded
at their intended merchandising temperature.
Before loading products, allow the equipment to operate empty for at least two hours.

PREVENTION

- Do not block the lower ventilation grille with the packages about to be loaded.
- Do not over hang the shelf.
- Do not press the product against the rear wall
- Never exceed the shelf weight limits.
ELECTRONIC TEMPERATURE CONTROL
The unit is provided with an electronic temperature control that controls the operation of the unit
based on the temperature of the air entering the evaporator at the front of the unit.
In order to achieve the desired product temperature, the electronic control is factory adjusted to turn
off the refrigeration system at 28ºF and start it at 39ºF.
When you plug the unit in, the control display will illuminate. However, there is a start-up delay of 2
minutes before the compressor(s) are energized. This delay avoids the possibility that during a pow-
er failure the compressors are forced to restart before the refrigerant pressures are equalized.
The control has been factory-adjusted with a defrosting cycle scheduled to last 6 minutes every hour
to ensure that the evaporator performs without any ice build-up.
None of the factory-programmed electronic control parameters can be modified unless an access
code is entered (only your distributor’s technical personnel have that code).

The CTRH-4 unit has a single hermetic compressor.
The CTRH-4 condenser must be inspected every 6 months as part of a routine preventative
maintenance schedule. Clean the condenser coil if necessary.
In the event it is believed that the unit has had a “freeze up” condition due to operation of the unit in
high temperature or humidity conditions the evaporator can be thawed by emptying the cabinet of
product and removing power until the coil is clear.
The lamp can be turned off with the switch located at the left side of the upper section, near the lamp.
When the equipment operates, condensed water from the environment is collected on the
evaporator. During each off-cycle, the water drains to the evaporator tray located at the bottom of
the unit where it is evaporated using the heat from the refrigeration system.

CAUTION
SHELF SPECIFICATIONS
MAINTENANCE GUIDELINES
www.ojedausa.com |8
The equipment has been exclusively designed to maintain the proper temperature of packaged fresh
food and beverages. Because the unit is not designed to cool the product down quickly, the product
must be loaded at its appropriate temperature.
- Do not remove grilles or panels that require using tools to be accessed
- Do not keep the unit running unloaded. UNPLUG IT when you are not planning to use it.
Using any electrical or electronic equipment entails the compliance with some fundamental rules.
- Do not touch the unit with wet hands or feet.
- Do not install the equipment outdoors.
- Do not remove or ignore safety devices.
- Do not leave objects on top of the unit.
- Do not climb on top of the unit.
- Never use direct or indirect water jets on the unit.
- Do not allow the electronic control to be adjusted by customers or unqualified personnel. For
any adjustment you must contact your distributor.
- Verify that the hot air stream from the condenser towards the back of the unit is not directed
to other refrigeration units, which would compromise their operation.
- Under no circumstance should you block the front grille of the unit.
THE MANUFACTURER DOES NOT ASSUME ANY RESPONSIBILITY ARISING FROM DAMAGES
CAUSED BY IMPROPER, INCORRECT, OR ERRONEOUS USE.
It is important to instruct the user on the operation of the equipment according to this instruction
manual, and to make sure that said manual is within reach of any operator that might use the unit.
The shelves have been designed to withstand the rigors of normal use and loading capacity not to
exceed 40 pounds per square foot evenly distributed weight per shelf:
This load limits must not be exceeded to prevent potential damage to the shelf and/or injury to users.
Regularly and carefully cleaning the equipment prevents deterioration and product alteration.
CLEANING THE UNIT
Clean every week with only a damp piece of cloth and neutral soap each external and internal sur-
face, and dry them with a clean soft cloth.

MAINTENANCE GUIDELINES CONT’D
www.ojedausa.com |9
Never use flammable or abrasive products. The unit must never be cleaned with water jets.
IMPORTANT: During maintenance and cleaning operations, make sure that good visibility conditions
exist in the working area, using other light sources in case it is needed. Be very careful when
working with moving and/or high-temperature parts.
CLEANING THE CONDENSER COIL
IMPORTANT WARRANTY INFORMATION:
Condensers accumulate dirt and require regular cleaning. Dirty condensers result in compressor
failure, product loss, and lost sales; which are not covered by warranty
If you keep the condenser(s) clean you will minimize your service expense and lower your electrical
costs. The following is a step-by-step guideline for the cleaning of the condenser(s):
1. Disconnect power to the unit.
2. Take off front lower grill assembly by removing the two (2) screws in the top corners.
3. Clean off accumulated dirt from the condenser coil(s) using a vacuum and/or a damp rag.
4. Replace the grill assembly.
5. Connect power to the unit and verify that when required the condensing unit(s) are running.
If you cannot remove the dirt adequately, please call your refrigeration service company.
