1. INSTRUCTIONS THERMAL AIR FLOW MODEL HOVA BATOR INCUBATOR NOTE It is recommended that you operate the incubator with a small quantity of inexpensive eggs to be assured of your operating procedure and the performance of the incubator before attempting to hatch large quantities of eggs or expensive eggs Keep Reptile eggs away from moving air See Warranty on Page 4 LOCATION The location of the machine is important to successful operation A room temperature from 70 to 80 F is ideal and fresh air without drafts is necessary A well ventilated base ment room is often just right Be sure no direct sunlight strikes the incubator and that it sets level A consistant room temperature within a few degrees is best CAUTION Do not place on fine furniture due to possible water spillage or leakage NOTE An Incubator or Brooder is designed to bring normal room temperature to the desired temperature Room temperture of 60 F or below will reduce the temperature in the incubator Room temperature change of 10 F or more will change temperature in incubator and is more pronounced below a temperature of 70 F SET UP THERMOSTAT STEP 1 BRACKET Unpack the incubator from box itis packed for shipping STEP 2 WAFER amp ADJUSTING SCREW THERMOMETER Next remove the thermometer and brass thermostat wafer Also remove the wingnut and from underneath the liner adjusting screw which is under the brass waf2. 9 Improper ventilation insufficient oxygen 10 Insufficient moisture 11 Too high temperature 12 Too low temperature 13 Probably too high temperature Most frequent causes of poor hatches 14 Temperature too high 15 Too low moisture 16 Improper turning or setting 17 Hatching trays too smooth 18 Low average temperature 19 Poor Ventilation 20 Navel infection in incubator 1 Use young vigorous males 2 Do not hold eggs longer than 14 days Keep at temperatures of 50 55 F in moist atmosphere Gather often 3 a Check accuracy of thermometer Check thermostat heating element current supply Check operating temperature againstinstructions b Do not fumigate at high concentrations during the first 5 days of age 4 See suggestions 2 above and see Note below 5 See suggestions 3 above 6 Turn at least 3 times preferably 5 in 24 hours 7 Check vitamin and mineral content of breeder mash 8 Avoid close inbreeding 9 Increase ventilation of incubator and incubator rooms avoid drafts 10 Increase humidity during incubation wet bulb 820 860 add water to second trough last 3 days wet bulb 90 92 during hatching time See 3 above and see Hatching page 3 See 3 above and see Hatching page 3 See 3 above and see Hatching page 3 See 3 above and see Hatching page 3 See 10 above See 6 above Set eggs large end up Use wire bo
