PREPARING THE DEVICE FOR STARTUP

The unit must be properly installed and located in accordance with the installation instructions before it is used.
3.1. Installation requirements

• Always use a dedicated circuit with the amperage stated on the unit.
• Do not overload the circuit.
• Do not use extension cords.
• Never use adapters.
• Never plug in more than one unit per electric circuit.
• If in doubt, call an electrician.
  IGLOO will not warranty any equipment that is connected to an extension cord or adapter plug.
  The equipment may be turned on after confirmation of the fire protection efficiency with results of measures performed according to binding regulations!

3.2. Unit location

• Remove cardboard angles and protective foil.

• Place the unit on an even and hard base. Then level the unit with the leveling legs. (Figure 5) For units with casters, use wheel brakes to immobilize the unit during operation. (Figure 6)
  

• To ensure proper operation the unit must be leveled from front to back and left to right with the leveling legs.

• The unit may malfunction if improperly leveled.

• Be sure there is sufficient ventilation around the entire unit

• Select a location away from heat and moisture-generating equipment.

• Avoid installation in high ambient or humid location.

• Humidity may cause rust, and condensation around the glass or stainless and decrease the efficiency of the unit.

3.3. Connection and start-up

• The first cleaning of the equipment should be provided right after unpacking, and before turning it on. The unit should be cleaned with water at a temperature not exceeding 40°C with a neutral detergent. For washing and cleaning the equipment, it is prohibited to use products containing chlorine and sodium varieties, which destroy the protective layer and components of the equipment! Any residue of adhesives or silicone on metal elements should be removed only with extraction naphtha (not applicable to items made of plastic!). Do not use other organic solvents.
  When cleaning the unit, do not use a water jet. The unit should be cleaned with a moist cloth.

• Check whether the water outflow ball valve is closed. (Figure 1/8)

• Fill the bain-marie tank with the proper amount of clean water.

• Place cross-bars under containers on the bain-marie tank. (Figure 2)

• Place empty containers in the chamber according to (Figure 3)

• Place the plug of the connecting cable directly in the plug-in socket. (it is forbidden to connect the device by means of extension cords or dividers!)

• Turn on the main switch (Figure 7/1), which activates the electric heaters of the bain-marie tank.

• Set the desired temperature on the thermostat control panel. (Figure 7/6)

• After obtaining the desired water temperature, put hot grocery products in containers.

• Turn on the lighting switch. (Figure 7/2; 3)

UNIT START-UP

The temperature of the heated display space may vary. It depends on numerous factors, such as the amount and temperature of products placed in the device and the temperature of the surroundings. The equipment should be placed in a dry and well-ventilated place.

Remarks and indications

•  Before placing hot products in the display case, an empty display case should operate until the desired working temperature shall be obtained.
• Do not block any ventilation holes, as this could hinder the front glass hot air inlet. (Figure 1/5)
• Do not place cold products in the unit.

4.1 Water level in bain-marie tank
Before connecting the water bain-marie it is essential to check the closure of the ball valve located below the display case body (Figure 1/8) and fill the tank with the proper amount of clean water. We pour the water directly into the bain-marie tank (ex. With rubber hose) to avoid flooding the electric part!
The optimal level of poured water should fall slightly above level (2) (Figure 8). The level of poured should not be too high, as this can prolong the water heating time. Apart from the above, the water may not reach the proper, high temperature, and heaters may work continuously, which will cause greater power consumption and quicker wear and tear of the heaters.
To ensure minimal electric energy consumption, it is essential to:

• Add water of the highest possible temperature in order to shorten the actuation time.
• When the unit is operating, please cover the bain-marie tank with containers in order to decrease water evaporation and shorten the water heating time.

Bain-marie is equipped with an SPW-4 water level regulator used to control and manage tank water levels. This regulator is equipped with sound and light signaling (Figure 7/4, 5) illustrating bain-marie operating conditions.
Green diode — signals low water level, the heating function is still active — pour the water into the tank, until the diode will be off.
Red diode — signals a very low water level in the tank, the heating function is still active (until sound signaling will be activated) — it is absolutely necessary to pour the water until the red diode, and then the green diode will be off.
When the bain-marie tank is properly filled with water, control panel diodes should not be illuminated at alt

2. Optimum fluid level sensor (green diode shall illuminate when fluid falls below this level)
3. Minimum fluid level sensor (red diode is illuminated)
4. Water temperature sensor
5. Tank water outlet hole

4.2. Temperature regulation
Bain-marie is equipped with a mechanical temperature regulator. The temperature sensor is located in the bain-marie tank (Figure 8/4). We set the desired water temperature in the tank (Figure 7/6) with the help of regulating the knob by turning it and setting in the proper position. Turning the knob clockwise increases the set temperature, and turning it in the opposite direction causes the decrease in temperature. Turning the knob left; until it reaches the final position turns off the heaters, despite the fact that the power supply is activated.
4.3. Lamp system
The lamp system includes ceramic infrared radiators and bulbs aimed to operate in high temperatures. Infrared radiators are used for additional, superficial dish heating. They use the phenomenon of temperature radiation, aiming in absorbing and changing the radiation energy falling on heated dishes into heat. Radiated waves fall through air without any difficulties and do not emit heat until they reach the heated surface. Bulbs and infrared radiators may be turned on/ turned off independently with switches placed on the control panel (Figure 7/2;3).

MAINTENANCE

• Do not use steel wool, abrasive cleaners, bleach or cleaners containing chlorine or sodium to clean the unit.
• Do not use a pressure washer or water jet to clean the unit.
• The first cleaning of the unit should be done right after unpacking and before turning it on.
• The unit should be cleaned with warm water and mild soap.

5.1 Cleaning and maintenance
It is recommended to make a break in the exploitation of the device once a week in order to clean its interior. Remove the dirty water from the tank by opening the water outflow ball valve placed below the body of the unit (Figure 1/8).

• All maintenance services need to be performed after disconnecting the equipment from the power supply!
• Protect electric installation against any damage or water spillage.
• Do not use water stream to clean the equipment, only a moist cloth.
• Do not use any sharp objects to remove din!
• Devices with wheels can’t be used on uneven surfaces!
• When cleaning inside of the device do not leave the front glass panel lifted in the aluminum profile, this may cause damage to the glass and is not covered by a warranty. Please remove the glass with profile during the cleaning process. (Figure 10)
