3. LOCATION

1) Cut the shipping band and remove the carton.
CartonIMPORTANTThis refrigerator/freezer is not intended foroutdoor use. Normal operating ambient
temperature should be within 5°C to 32°C.
Carton (Base)For best operating results:

Shipping Band

Fig. 42) Position the unit in a selected site..

* The refrigerator/freezer should not be locatednext to ovens, grills or other high heat producing
equipment.

3) Clean the interior with a soft cloth soaked in coldor warm water containing the proper amount of
neutral cleaner and wrung dry.

* The location should provide a firm foundation for
the equipment.

[Caster models]
4) Level t he r efrigerator/freezer i n both t he l eft-to right and the front-to-rear directions. To adjust theheight o f the unit, i nsert the spacers (accessory)
into the caster joints. Usue the spanner (accessory)
to loosen or tighten the casters .After making theunit level,tighten the casters securely .Lock the
stoppers of the front casters.

* Avoid a site where dripping is not allowed.
E s p e c i a l l y, a s i d e - b y - s i d e o r b a c k - t o - b a c kinstallation (possibly with other manufacturer’s unit)
may cause condensation between the two units,
resulting in dripping onto the floor.
* Do not expose the unit to direct sunlight or higher
temperatures.
* Allow at least 50 cm clearance between thefront panel air inlet/outlet and the wall or otherequipment for proper air circulation. The front of
the unit should have enough space for smoothadjustment of the cabinet temperature. If theambient temperature can exceed 38°C, allow atleast 10 cm clearance from the wall at the side of
the machine compartment to prevent overloading
and damaging the refrigeration circuit.

6. ELECTRICAL CONNECTIONSCAUTION
The height of the adjustable legs must be within
9 - 12 cm (or 15 - 18 cm for some models).
If extended too much, the legs may become
weak or the adjusters can come off, causing
unexpected injuries.

IMPORTANTThis refrigerator/freezer is provided with nopower switch or earth leakage circuit breaker,
but with overcurrent protection (fuse) only.
Install a switch rated at least 10A on the main
power supply.

5. SHELF, SHELF CLIP AND SHELF HOLDER* This refrigerator/freezer must be plugged into
the separated power receptacle which is readilya c c e s s i b l e a n d h a s e n o u g h c a p a c i t y. T h emaximum allowable voltage variation should notexceed ± 10 percent of the nameplate rating. See
the nameplate.

* The shelf is adjustable in 2.5 cm increments. Adjust
the shelf clips according to the height of stored
items.
* To attach the shelf clip, insert the upper tab into
an adjust hole in the shelf post to hook the shelfclip, and push the lower tab into another adjusthole until it locks in place. To detach the shelf clip,
reverse the above procedure.

* If the supply cord is damaged, it must be replacedby the manufacturer, its service agent or similarly

two shelf holders each to the left and right frames
and one to the center frame as shown below.

4. This refrigerator/freezer is designed only
for temporary storage of foods. Use for any
other purposes (e.g. storage of chemicals
or medical supplies such as vaccine andserum) could cause deterioration of stored
items.
5. Do not throw anything onto the shelves orload more than 60 kg on each of them. They
may fall off and cause injury.
6. Do not store bottles or cans near the air
outlet. They may freeze up and break,causing a risk of injury.

the adjustable range. The actual cabinet
temperature depends on the ambient
temperature and other conditions.

10. Do not block the air inlet/outlet with foods.
11. Do not pack the cabinet with foods. Allowsome space between them to ensure good
air flow.

The cabinet temperature is factory-adjusted to
1°C for the refrigerator and -20°C for the freezer. If
necessary, readjust the temperature as follows.

12. Do not put in warm or hot foods. Let themcool first, or they will raise the cabinet
temperature and could deteriorate otherfoods in the cabinet or overload therefrigerator/freezer.

5. SHUT DOWN

The compressor stops when the cabinet temperaturereaches down to the set temperature, and starts
when the cabinet temperature rises to the set
temperature + 4°C. Accordingly, the average cabinet
temperature will be around the set temperature +2°C.

1) Before shutting down the unit, move the stored
foods into another refrigerator/freezer.
2) Unplug the unit or disconnect the main power
supply.

ENGLISH
1. INTERIOR, EXTERIOR, SHELF

2. AIR FILTER* Clean the interior and exterior at least once a week
for sanitary use.

Plastic mesh air filters remove dirt or dust from theair, and keep the condenser from getting clogged.
If the filters get clogged, the refrigerator/freezer’s
performance will be reduced.
Check the filter at least twice a month. When clogged
or when the temperature controller shows “cH”, usewarm water and a neutral cleaner to wash the filter.
Do not operate the unit with the air filter removed, orthe condenser will get clogged, resulting in failure.

* Clean off the interior and exterior with a soft cloth
soaked in cold or warm water containing the properamount of neutral cleaner and wrung dry. Do not
use a water jet to clean the machine compartment.
* Chemical agents other than neutral cleaner mightcause damage to the interior and exterior surfaces.

1)Remove the screw under the front panel and open
the front panel.

* Any remaining detergent will damage metal orplastic surfaces. Use a soft cloth dampened withwarm water to wipe it off.

2) Remove the air filter from the condenser.

* Do not use the following items. They could damage
painted or plastic surfaces:

3) Wash the air filter carefully with cold or warm
water containing the proper amount of neutral
cleaner. Rinse and dry the air filter thoroughly.

Polishing powder, alcohol, thinner, benzine, acidic
or alkaline detergent, hot water, petroleum, soap
powder, metal scourer or brush, etc.
Especially detergent to clean grease on ventilator
or microwave.

4) To refit the air filter, put the two tabs into the heatexchanger line or fins in the condenser, and tightly
attach the air filter over the condenser.

Note: Some solutions other than the above may
also damage painted or plastic surfaces.
Immediately stop using such solutions if
they cause any problems.

3. BEFORE CALLING A SERVICE AGENTIMPORTANT
1. If the screen on the operation panel indicatesan error code or something seems wrong
with the unit, check for possible causes
according to the following instructions. If the
problem still exists, immediately contact anauthorized Hoshizaki service company.

* The door gasket and its contact surface getsoiled easily. Clean every surface of these parts
thoroughly. Remnants of food will accelerate aging.
* Use a cloth to wipe off any water staying inside thecabinet.

2. When contacting a service company, let themknow the model name, serial number, date of
installation (see warranty card) and state of
the trouble.
3. Do not attempt to repair the unit yourself.
