Ⅲ. Installation

1 Carriage

2 Before Installation

1) Packing

- For exported machines, first remove nails from the

wooden container and take out slats and boards. Please

recycle packaging materials in accordance with your

country’s regulations.

- Please confirm that the roaster, cyclone, manual, and

toolkit have been included.

2) How to carry

- Weight: approximately 430kg ( 950 lbs)

- Use a forklift to transport over level ground

1) Check point

1)-1 Electricity

This machine is manufactured to utilize a standard Korean wall socket.

Please install regarding your country’s voltage requirements.

1)-2 Gas Pressure

Install according to the requirements of your gas system. It is necessary to install a separate safety

device for preventing gas leaks in addition to the built-in safety device. Please see specifications for

gas pressure requirements.

1)-3 Exhaust Condition

Place your coffee roaster in a place where you can install the exhaust pipe. Please note that shorter

exhaust distances make for ideal air-flow conditions. 6

3. Installation

* When installing an afterburner: Do not install it near a fire source! Duct made of heat-

resistant material is required.

1) Duct Work (Exhaust facility)

Combustion occurs in this equipment and it should be installed in a dry place with good ventilation as

close as possible to a wall so that a shorter exhaust pipe can be used. And it is also recommended that

the exhaust pipe used is exclusively for roasters to consistently maintain quality. Caution should be

used in the case where the duct is connected to the central exhaust system as it may negatively affect

the exhaust flow and inlet temperature during roasting due to the change in the exhaust impedance.

1)-1 Drilling holes in the wall

Exhaust pipe is Ø150mm ( Ø200mm in case afterburner is installed)

Cooling pipe is Ø100mm

(Location of the center of the holes: 2000mm above the floor, and 2300mm in case afterburner is

installed)

In case they are required to drill in the wall or glass, contact a specialist after checking the material.

1)-2 The construction cost of external exhaust pipe work is not included in the equipment price and it is

required to install it separately at your own expense.

In this equipment, the exhaust pipe is made of stainless steel. Heat-resistant and corrosion-resistant

material should be used for safely.

It is recommended to install the equipment using an exhaust pipe with a length shorter than 4m, if

possible, and when an exhaust pipe is longer than 10m an additional blower needs to be used.

Otherwise, there may be an exhaust problem during roasting due to improper airflow. Please contact a

specialist for the duct construction.

2) Gas supply

This information is for your gas facilities companies.

2)-1 In case of Natural gas, it is recommended to secure a shared gas pressure of equipment of more

than the minimum 2kpa /0.290psi considering gas consumption.

2)-2 Things to be prepared before the equipment is delivered: please have the gas line(s) set up near

where you would like to install the roaster.

2)-3 Gas consumption by equipment

Coffee Roaster: Natural gas: Max. 21,000kcal / LPG: Max. 1.8kg

Afterburner: Natural gas: Max. 30,000kcal / LPG: Max. 2.8kg

2)-4 Securing sharing gas pressure of equipment

It negatively affects the quality of the roasting due to low heat when gas pressure is not sufficiently

provided.

a. Natural gas: Gas pressure should be more than 2kpa /0.290psi

b. LPG : Gas pressure more than 2.8kpa / 0.406psi

2)-5 Gas pipe specification: 15A or higher

2)-6 Caution when installing a fuse cock: Be sure to check gas consumption beforehand

2)-7 Be sure to install a gas leak alarm system.

2)-8 Install a pressure gauge in the front end of the equipment to check if normal pressurized-gas is

supplied.

2)-9 Check the standard specification of gas pipe as pressure may vary depending on the size and

length of a gas pipe. The shorter the gas pipe, the better.

2)-10 How to build a gas pipe when installing the afterburner together with the roaster:

Build separate pipelines at the main pipe to supply gas constantly during roasting without affecting

firepower.

In case of the simultaneous connection at one pipeline, the amount of gas supplied to the roaster will

be rapidly reduced when operating the afterburner, which results in lack of firepower causing which

affects the roast. It is recommended to use separate pipelines if possible.

3) Power supply

Be sure that the total power consumption of all peripheral devices does not exceed 80% of the amount

of power to be supplied.

We recommend that you raise voltage in the event there that this condition is not met.
