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.
