Section 1
WARNING: THE CARBONATOR IS AN INTEGRAL PART OF THE UNIT AND IT
SHOULD BE NOTED THAT THE CARBONATION PROCESS INVOLVES
THE USE OF HIGH PRESSURE AND POTENTIALLY NOXIOUS GAS. AS
SUCH SUE CARE MUST BE TAKEN WHEN USING THE EQUIPMENT.
WARNING: CARBON DIOXIDE LEAKS ARE POTENTIALLY FATAL IF
CONCENTRATIONS RISE TO A DANGEROUS LEVEL. IN VIEW OF
THIS THE INSTALLATION SHOULD BE REGULARLY CHECKED FOR
INTEGRITY AND THE GENERAL AREA OF INSTALLATION PROPERLY
VENTILATED AT ALL TIMES.
IT IS RECOMMENDED THAT A CO2 LEAK DETECTOR IS FITTED IN THE
VICINITY OF THE EQUIPMENT.
THE UNIT SHOULD NOT BE INSTALLED IN A ROOM WHERE SHOULD
THE CONTENTS OF THE CO2 BOTTLE BE EVACUATED INTO THE
ROOM, CO2 LEVELS WOULD REACH LETHAL LEVELS.
WELBILT RECOMMEND THAT ONLY 5 OR 7 KG CO2 CYLINDERS BE
USED WITH THE ALBI APPLIANCE.
THE CARBON DIOXIDE CONCENTRATION IN A ROOM AFTER A TIME -
T - CAN BE CALCULATED AS.
C = (Q / N V) [1 - (1 / EN T)] + (C0 - CI) (1 / EN T) + CI (1).
WHERE:
C = CARBON DIOXIDE CONCENTRATION IN THE ROOM (M3/M3)
Q = CARBON DIOXIDE SUPPLIED TO THE ROOM (M3/H
V = VOLUME OF THE ROOM (M3)
E = THE CONSTANT 2.718
N = NUMBER OF AIR SHIFTS PER HOUR (1/H)
T = TIME (HOUR, H)
CI = CARBON DIOXIDE CONCENTRATION IN THE INLET VENTILATION
AIR (M3/M3)
C0 = CARBON DIOXIDE CONCENTRATION IN THE ROOM AT START,
T = 0 (M3/M3)
THE VENTILATION IN THE ROOM WHERE THE UNIT IS INSTALLED
SHOULD NOT ALLOW THE CO2 CONCENTRATION TO EXCEED
5000PPM WORK PLACE 8 HOUR EXPOSURE LIMIT.
BEFORE INSTALLATION A WORK PLACE RISK ASSESSMENT MUST BE
PERFORMED CONSIDERING THE RISK ASSOCIATED WITH THE USE OF
CO2.
