INSTALLATION AND ACCESSORY PARTS

Installation and Accessory Parts

Unpacking Your Freezer

1.Remove all packaging material; this includes the foam base and all adhesive

tape holding the freezer accessories inside and outside.

2.Inspect and remove any remains of packing, tape or printed materials before

powering on the freezer.

Adjusting Your Freezer

1.Your freezer is designed for freestanding installation only. It should not be

recessed or built-in.

2.Place the freezer on a floor strong enough to support it fully loaded.

3.When moving the freezer, never tilt it more than a 45-degree angle. This could

damage the compressor and the sealed system.

4.If the freezer is tilted let it stand in an upright position for at least 24 hours prior

to plugging. This is to allow the refrigerant to settle.

·Proper Air Circulation

l To assure your freezer works at the maximum efficiency it was designed for,

you should install it in a location where there is proper air circulation,

l Plumbing and electrical connections.
l The following are recommended clearances around the freezer:

Sides…………..2”(50mm)
Top. ……………2”(50mm)
Back…………..2”(50mm)

INSTALLATION AND ACCESSORY PARTS

Installation and Accessory Parts

l Do not over fill freezer for proper internal air circulation.

Electrical Requirement

l Make sure there is a suitable power Outlet (220V) with proper grounding to power the

freezer.

l Avoid the use of three plug adapters or cutting off the third grounding in order to

accommodate a two-plug outlet, this is a dangerous practice since it provides no effective
grounding for the freezer and may result in shock hazard.

Install Limitations

l Do not install your freezer in any location not properly insulated or heated e.g. garage etc,

your freezer was not designed to operate in temperature settings below 32· Fahrenheit.

l Select a suitable location for the freezer on a hard even surfaces away from direct sunlight

or heat source e.g. radiators, baseboard heaters, cooking appliances etc, Any floor
unevenness should be corrected.

Installing Casters(delete?)

Your freezer can be equipped with casters for easy moving. We recommend
installing casters before using the freezer. Install following these easy steps:

1.Remove the food basket from the freezer.

2.Slowly tilt the freezer on its side.

3.Tap one caster into the bottom of the freezer. Fasten the caster into place

with screws provided.

4.Install the other three casters in the same manner.

5.Return the freezer to its upright position and replace the food basket.

Note: It is important to wait for 24 hours after installation before plugging in
the unit to allow the refrigerant to stabilize.

Once the freezer is in its proper place, plug it in an electrical outlet having 220
volts.
Set the temperature, on the temperature contrail knob.”1”being the warmest and
“7”being the coldest. Initially set the temperature on”4”. Place food inside the
freezer (green light will come on indicating that the freezer is in operation). After
using the freezer for 24 hours set the freezer to your desired setting.
In case you unplug your freezer or experience an electrical outage, allow 5
Minutes before plugging it back in.
(Note: If the freezer has been placed in a horizontal or tilted position for any
period of time wait 24 hours before plugging the unit in.)
Adjustable temperature dial:
Your freezer will automatically maintain the temperature level you select. The
temperature level you select. The temperature control dial has 7 settings plus
OFF.”1I”is the warmest,”7”is the coldest. Turning the dial to OFF stops cooling the
freezer. Set the dial to “4and allow 24 hours to pass before adjusting the
temperature to your needs.

Food Storage Basket

Your Freezer has 1 removable basket. It allows you to store food more accessibly
or you can remove it if not needed.

Defrosting and Draining The Freezer

·Defrost whenever the frost becomes 1/4” thick. Never use a sharp or

metallic instrument to remove the frost as it may damage the cooling
coils.(A punctured coil will void the warranty)

·Turn the temperature control to OFF position and unplug the unit. For

draining, place a tray beneath the outer drain plug. Pull out the drain dial
and rotate it so that the arrow points down ward. This will let the water flow
out into the tray.

·Remove the drain plug from the inside of the freezer. Defrosting usually

takes a few hours. To defrost faster keep the freezer door open. When done,
push the drain dial in and turn the arrow to the up position. Re-plug the
drain plug inside the freezer compartment. Note: monitor the container
under the drain to avoid overflow.

·Wipe the interior of the freezer and replace the electrical plug in the

electrical outlet.

·Rest the temperature control to the desired setting.

CIRCUIT DIAGRAM

Circuit Diagram

Brief description of principle about FHV5SGWW/7SGWW:

1.The red lamp is the alarm lamp. When the temperature>-15℃,
the lamp will be on.

2.The green lamp is a power indication lamp. When the power
is on, the lamp will be on.

3.Thermostat: When the temperature in the freezer is higher and
reaches the value for starting the machine, the thermostat will be
closed, the compressor will run; When the temperature in the
freezer is lower and reaches the value for closing the machine,
the thermostat will be open, thus the compressor will be stop
running.

MAINTENANCE SERVICE AND TROUBLE SHOOTING

Maintenance Service and Trouble Shooting

12.1 System Trouble shooting

12.1.1 Servicing freezer

(1)Check the whole circuit of freezer, if there are wire connections
came off, any wires broken, or a short circuit.

(2) Check the insulation of the whole freezer. At normal situation,
the resistance is greater than 2 mebohms; if it is less than 2
mebohms, please make a further check of the freezer resistance.
Set the voltmeter to R1 Ohm position, put the two voltmeter leads
pencils into L and N terminals respectively, watch the indication
of odometer. The normal value is several Ohm to tens of ohm. If
the resistance is zero, means that there is a short in the freezer
circuit or there is a short caused by a bad compressor or fan
motor. The reason should be found out and repaired. If the
resistance is too big or infinite, this means that there is broken
circuit, please check and solve it.

After the above checks, the freezer will not have any
electrical problem and you can switch power on for further
completely check.

MAINTENANCE SERVICE AND TROUBLE SHOOTING

Maintenance Service and Trouble Shooting

12.1.2 Reasons of electricity leakage of freezer

(1) Leakage of compressor: mainly because of serious vibration,
the motor coil of compressor contacts with the shell, the coat of
enameled wire will come off some where and connect with shell.
Other reasons may be over voltage, insufficient of voltage,
adverse circumstances (temperature too high, ventilation and
heat radiation to bad) for freezer, thermal protection unit out of
order, etc. They will make the motor coil over temperature,
insulation material loose, insulation is damaged then electricity
will occur.

(2) Leakage of motor connection terminals: the connection
terminals of fully enclosed compressor are made from high
temperature soda glass sintered ceramics, around the terminals
are filled with a high polymer. The terminals and insulation
material must have the same linear expansion coefficient, the for
requirement between terminals and the shell is more than 0.5
million ohm. The reason of terminal leakage is that soda glass is
broken or there are conductive materials such as water, dirt, etc.,
adhered to terminals.

MAINTENANCE SERVICE AND TROUBLE SHOOTING

Maintenance Service and Trouble Shooting

If electricity leakage occurs outside the compressor, please use
tetra chloromethane or alcohol to clean it. If the leakage occurs in
the inner of compressor, it needs to be changed.

(3) Leakage of temperature controller: because of too long a
period of service or too high temperature, or too much dirt, or too
high humidity, there may be electricity leakage. If it has been
defined that there is leakage of temperature controller, please
change.

(4) Leakage of starting relay: during mounting and repairing,
screw of relay lead is easy to contact the shell and leakage will
then occur. If you suspect the relay is bad, check it. If there is
leakage, please make the connections again and leave a piece of
insulation paper under the screw.

(5) Leakage of fan: because of too high humidity of freezer
environment or a bad fan controlling unit, the fan is burned after
long time operation and thus causes leakage. Using voltammeter
to measure the insulation resistance between each respective
connection terminal and the freezer body, if the resistance is too

little, means there is leakage caused by humidity; if the resistance

Is zero, means the fan coil is burned or short-circuited. Please
change the fan.
