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

75o

F/55oRH.

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.

Care must be taken to ensure that air drafts around the cooler

are kept to a minimum. A minimum space must be kept

between the cooler and air sources such as air conditioner

supply or return grilles, vent hoods, appliance condenser air

intake and discharge, outside doors, fans, or other air movement

devices (Fig.2).

The following horizontal distance should be considered

minimums unless special precautions are taken to prevent

interruption of the ALPA air curtain:

-5’ from appliance condenser air intake and discharge

-10’ from air conditioner supply or return grilles

-10’ from vent hood

-15’ from open doors

The location of the cooler must be kept away from sources of

heat and humidity including direct sunlight (Fig.3), toasters,

ovens, coffee warmers, other appliances condenser air

discharge, infrared heaters, or other heat generating appliances.

The unit should be leveled prior to operation.

The unit must have casters, 6” legs, or sealed per NSF

guidelines as shown in Figure 4A and 4B.

Figure 2

Figure 3

Figure 4A Figure 4B

The power cord of this appliance is equipped with a 3-prong (grounding) plug which mates with a

standard 3-prong (grounding) wall outlet to minimize the possibility of electric shock hazard from this

appliance.

ALPA units require a dedicated outlet with the type of receptacle as shown in the chart.

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

The ALPA series of units are 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.

When loading products:

Figure 5 Figure 6

- Do not block the lower ventilation grille with the packages about to be loaded. (Fig. 5)

- Do not block the return vents that ensure a proper refrigerated air circulation. (Fig. 6)

- Do not over hang the shelf.

- Do not press the product against the rear wall

- Never exceed the shelf weight limits. (See Shelf Specifications Pg.8)

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 35ºF and start it at 39.5ºF.

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 ALPA-36 and ALPA-55 have a single hermetic compressor. The ALPA-77, ALPA-99, and ALPA-

120 have two hermetic compressors that start in two steps with a delay of 10 seconds to reduce the

in-rush of current to the unit.

The ALPA units incorporate a “maintenance free” condenser design in the refrigeration system which

reduces the need for the regular cleaning process that fin and tube condensers require. Besides the

savings in preventive maintenance costs, energy expenses will be stable throughout long periods of

time since the condensers will remain “clean and unobstructed”.

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 inspected by removing the floor of the

inside of the unit. In the event the evaporator is frozen, it can be thawed by emptying the cabinet of

product and removing power until the coil is clear.

The condensing unit can be pulled out, sliding it approximately 40 cm (16”) to allow servicing the

condenser motor(s), compressor(s) and electrical components. In order to service the condensing

unit, remove the two screws that hold the lower front grill (one at each side). Remove the screws that

hold the front bracket that clasps the condensing unit and slide it gently out to have access to the

components you want to check.

Once completed, every component must be returned to its original location for proper operation.

The lamp can be turned off with the switch located at the left side of the upper section, near the lamp.

The night curtain should be pulled closed whenever the unit is not required for the active

merchandising of product.

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

Part Number 100330038 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 with the following

not to exceed evenly distributed weight per shelf:

ALPA-36: 27 kg (60 Lbs).

ALPA-55, ALPA-77: 50 kg (110 Lbs).

ALPA-99, ALPA-120: 60 kg (132 Lbs)

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

Part Number 100330038 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.

Part Number 100330038 www.ojedausa.com |10

CLEANING DRAIN LINES (ALPA 55-120)

Over time it is likely that the drain lines will become clogged

which will result in water overflowing the condensate pan and

onto the floor. This is a standard maintenance item and will

not be covered under warranty.

The drain lines can also be accessed by removing the bottom

panel from the inside of the unit. (Fig. 7). Both holes for the

drain lines can be located (Fig. 8).

Obstructions can be removed either by compressed air or

nitrogen, or physically removing the obstruction with a drain

cleaner.

DO NOT USE A CHEMICAL DRAIN CLEANER AS THIS WILL

VOID THE WARRANTY AND POSSIBLY DAMAGE THE UNIT.
