This is the additional information provided by my friend Adebisi  Adekunle.
 
1.1 Harvesting Rules - follow the rules below to harvest honey  successfully.
EQUIPMENT
1. Have all equipment ready! Harvest hive with top bars to replace bars  
removed for harvest, smoker, containers, knife etc.
 
Containers: Use only aluminium, tin, galvanised iron or plastic
Do not use: copper, iron, steel or zinc, they dissolve into the honey and  
may affect colour and flavour and might reach toxic levels.
Use a damp cloth over the t bars/ frames to control the bees and smoke  bees
 
WHEN TO HARVEST
2. Harvest according to the conditions of the colony and the time of  season.
Weather - pick a cooler day when temp is between 15C and 25C. Temp of   less 
than 25 C makes uncapping easier.
Choose time of day to help preserve the comb - early morning or evening  when 
weather hot (flowering season)
Strong colonies, you can harvest earlier
Harvesting can start 3 - 4 weeks after the start of a good honey  flow.
 
DO NOT
Do not smoke too heavily as it will contaminate the honey. Do not burn  
anyhting chemically treated, as chemiclas will be included in the smoke.
Do not harvest combs from brood area or combs containing brood
Do not harvest uncapped honey called green or unripe honey. It will  ferment. 
If honeycomb uncapped/wet, contains too much water. Must dry out or  honey 
will ferment.
Dry out by leaving honey supers/t bars in arm rooms at 30 - 35 C and  
circulating warm air theough them or dry out by placing in a Langstroth super  and 
blowing air through the entrance.
 
WHAT TO HARVEST
3 KTBH  Grade the combs as you remove t bars from the hive.
At the hive separate good combs to be further processed as first grade  
beeswax
 
or Before extracting separate/grade combs > light (good) dark  (old)
Separate combs containing uncapped honey ie wet green or unprimed honey,  
empty t bars/ comb at the edges of the nest or on the ends of the hive.
