WILLIAMS MODULAR COLDROOM

Operating Instructions

Please read these Operating Instructions before using your Coldroom.

1. Old Coldrooms

Please ensure any old/redundant refrigeration is disposed of safely and legally. We would recommend that doors are
removed prior to disposal to ensure safety.

2. Unpacking

This is to be carried out by the installer, who will remove all interior and exterior packaging and accessories.

3. Installation

The intended site for the coldroom should be level to facilitate accurate erection and to ensure correct operation of self­closing doors and proper drainage of condensate from the evaporator. If a freezer room is to be installed the provision
needs to be made for a 90mm floor.

An appropriate assessment should be undertaken by the user to avoid risk of slips, trips and other potential Health &
Safety risks. Consideration should be given to non-slip floor coverings or mats. These can be provided by Williams
Refrigeration.

4. Mains Connection

Your modular ‘made-to-measure’ coldroom will have been properly connected to the mains electrical supply during
assembly and installation. All necessary electrical components will be supplied. If you ever decide to relocate the
coldroom, consults a qualified electrician.

5. Locking Facility

On models with locking facility it is recommended that the key be removed from the lock during normal working use and
stored in a safe place. It is possible for the key to be damaged or knocked if left in the lock. This could result in having a
new lock fitted.

Removing the key from the lock will also prevent the possibility of accidental locking while the door is open. This will
prevent the door closing properly and cause the interior temperature to rise, this may results in loss of food if left in that
condition.

6. Door Release Mechanism

All users should familiarise themselves with how to use the internal door release before operating the room. Try the
release whilst the door is in the open position.

Regular checks and maintenance of the release is essential to ensure it is working co rrectly and prevent accidents.
Before entering the room, ensure that someone knows you are in there and how long you plan to be in there.
If you become trapped inside:

 DO NOT PANIC an emergency internal release device is fitted to this Williams room.
 Located on the door, at handle level, positioned to the left of the right hand side. (opposite the door hinge).
 Push the round (luminous) handle firmly in and the door will open, even if locked.
 IF THE DOOR FAILS TO OPEN, then there may be an obstruction to the release. Twist and rotate the release handle

and then push it very firmly in to the door. Repeat as necessary. Use the full weight of your body to aid you.

 Be cautious of items, which may have fallen and obstructed the door opening outside of the room.
 In the unlikely event that you are still unable to exit the room, activate the internal person trapped alarm switch, if

fitted.

7. Ventilation

It is essential to ensure that the room in which the equipment is installed is adequately ventilated. The condensing unit
and fans generate considerable amounts of heat and if operated in unventilated spaces, especially in warm weather, will
quickly cause the ambient temperature to rise to excessive temperatures. This can cause motor and compressor
overheating and possible damage to windings. At the very least such installation will cause the coldroom to use an
excessive amount of electricity and have an impact on its performance.

Operating Instructions

8. Thermometer

The controller measures in either Centigrade or Fahrenheit for the thermometer display. The thermometer should be
checked daily to ensure that the equipment is maintaining the correct temperature.

9. Controller

LED

Display

After you switch the room on the controller will diplay [---]. This is the self test phase.
A permanent indication on display OFF indicates the room is on standby. The only buttons that can be operated in this

state is the light switch ([UP] button) and the standby switch, which turns the room on/off standby ([DOWN] button).
During normal operation the display shows the room temperature or, if the controller is performing defrost the controller

will display DEF, the indication will remain until the defrost has finished.
An anomaly is reported on the display through the flashing of an abbreviation indicating its cause:

 HI / LO, High or low alarm temperature in the room.
 DO, Door open alarm.
 CHI, High condenser temperature.
 CLN, Periodic condenser cleaning.
 E1, Failure of probe T1.
 E2, Failure of probe T2.

By pressing button [INFO] you enter the information menu. In this menu you can start a manual defrost by scrolling to
[DF] holding the [INFO] button whilst pressing the [UP] arrow button. Also you can display the T1, T2, T3 temperature
probes just by scrolling through the options.

To exit this menu, press the [SET] button or after 30 seconds of no button activation the controller will automatically exit.
To operate the light switch, press the [UP] button.

10. General Produce Models

These models are designed to operate at +1°C/+4°C (34°F/39°F). Defrost is automatic. The temperature can be adjusted
via the electronic controller.

11. Fresh Meat Models with Electric Defrost

These models are designed to operate at –2°C/+2°C (28°F/36°F). The temperature can be adjusted if necessary by
setting the electronic controller.

12. Frozen Food Storage Models

These models are designed to operate at -18°C/-22°C (0°F/-8°F). The temperature can be adjusted by setting the
thermostat via electronic controller.

All equipment is factory set, condition on site will be different to the test conditions and it may be necessary to
perform certain adjustments to the parameters to obtain a perfect temperature cycle.

Operating Instructions

13. Defrost Operation

When defrost is in progress, the defrost indicator on the control panel will become illuminated.
On fresh meat and freezer coldrooms, every 6 hours the machine will go through an automatic defrost cycle, which lasts

for a maximum of 20 minutes. The refrigeration system is turned off whilst the electric defrost system is switched on. This
defrosts the evaporator coil. This operation raises the temperature of the coldroom slightly for a short period but does not
affect the stored product.

On GP coldrooms, when the machine goes into defrost the refrigeration system is turned of and the coldroom is allowed
to naturally defrost (off-cycle defrost).

14. Hi-Lo Alarm

The modular coldroom controller features a built in audio/visual Hi-Lo alarm. If the temperature within the room exceeds
the factory set alarm temperature for 45 minutes or more the control will emit an alarm signal through the display and the
buzzer. The alarm can be cancelled by pressing the [INFO] button.

15. Probe Fail Safe Feature

The Coldroom controllers feature a special fail-safe condition. In the event of a temperature probe failure the compressor
will not continue in normal sequence.

Instead the compressor will switch to a five minute cycle, which it cycles on for five minutes then off for five minutes . The
normal compressor cycle will be restored upon the repair of the probe fault. This feature is designed to avoid the
compressor overheating and preserve the temperature of the food within the cabinet.

16. Cleaning

For health safety and hygiene, as well as keeping the equipment in good condition, described below are some guidelines
on how to maintain your Williams Modular product.

Exterior: Normal day-to-day cleaning should be carried out with a soft cloth and soapy water. Never use abrasive
materials or cleaners.

Interior: Clean up all spillages immediately. Where prolonged door openings arise, ensure condensation is wiped off the
door and strip curtains are fitted. Clean interior and any shelving regularly in accordance with your cleaning schedule.
Always use a ‘food safe’ cleaning solution.

Check that the inner door release operates properly. This should be undertaken in the door open position. Gently rotate
side to side the release handle to ensure there are no obstructions. Person Trapped Alarms and lights should be regularly
checked for proper operation.

For efficient operation, do not overload the compartment or restrict airflow. Do not block air chute with shelving or product.
Ensure shelves are loaded safely. Do not obstruct the doorway or switches. Do not attempt to undertake maintenance on
the internal evaporator, fan unit or remote guards. This work should only taken by a qualified engineer.

17. Routine Maintenance

A competent, qualified person should carry out all maintenance. We recommend that you undertake regular preventative
maintenance using a qualified service provider in order to get the best from your equipment. The door inner release
should be checked for operation and lubricated as necessary.

18. Condenser Cleaning

Disconnect the coldroom from the electrical supply by unplugging.

The controller has a condenser clean alarm that is factory set, this alarm will sound every time the condenser needs
cleaning. The condenser, which is part of the refrigeration unit, is sited on the roof of the modular coldroom and requires
cleaning approximately four times per year. On rooms that are supplied with remote condenser units, the coil is located in
the condensing unit box. If your room has been supplied with refrigeration equipment by someone other than Williams,
the location may be different an you should consult your installation contractor and confirm its location. To clean the

5

WILLIAMS MODULAR COLDROOM

Operating Instructions

condenser, disconnect the mains supply, brush the fins vertically with a stiff brush, taking care not to damage the fins or
push dirt further and vacuum away. Remember to reconnect mains supply once finished.

Warning: Condenser blocking is the most common cause of equipment overload and failure – make sure that the
condenser coil is kept free of dust and dirt and regularly checked.

If there are further grease deposits remaining on the condenser call your Service Provider to carry out a full service.

NOTE: Non-compliance may invalidate your Warranty.

19. Cleaning / Replacing the Gasket

Door gaskets should be checked and cleaned regularly and replaced if damaged. To clean the gasket, wipe with warm
soapy water and a soft cloth, ensuring it is completely dry before closing the door. DO NOT use a sharp knife to clean or
scrape the gasket. Damaged gaskets do not seal correctly and can increase the amount of electricity consumed,
seriously affecting the efficiency and performance of the coldroom.

Damaged gaskets are easily replaced. To fit a new gasket – simply pull out the old gasket and
push the new gasket into the channel (gasket retainer) at the centre and work along the gasket
pushing the channel, continue in the same way on the other three sides, pushing the corners in
last.

20. Panel Joints

Inspect the panel joints when cleaning for any loss of mastic sealer or gaps appearing. Use warm soapy water to clean
along the panel joints with a soft cloth. Do not use stiff brushes as they may cause damage to the sealant. Replace any
missing sealant with silicon sealer (available from kitchen suppliers and DIY stores).

23. Breakdown

A competent qualified engineer must carry out breakdown repair.
In the event of a breakdown, please check the thermostat setting and fuse before calling the service engineer.

If the light on the coldroom is not working isolate the supply and change the bulb, if this does not cure the problem
change the fuse located on the exterior at the bottom of the control panel. If problem consists call an engineer.

When calling the engineer, please advise him of the model and serial number of the machine. These details are on the
identification plate inside the coldroom and should also be noted on the back cover of this booklet. Please ensure all
redundant parts are disposed of safely and legally.
