IMPORTANT SAFETY NOTE:

THE HEAT IN FRONT OF THE EVAPORATOR WHEN THE DOOR IS OPEN IS INTENSE. ALWAYS WEAR GLOVES, SAFETY GLASSES AND HEAT RESISTANT CLOTHING WHEN FIRING THE EVAPORATOR.


TROUBLESHOOTING GUIDE

Can’t keep a constant liquid level in the pans:

• Usemoredefoamer.(careful,tomuchdefoamercouldaltersyrupflavor).

• Thesiliconepartinthefloatboxarmisworneddownormisplaced.

• Thefloatboxarmneedstoberealigned.

• Thereisaleakinthefloat,it’sfillingwithsap.Repairorreplacethefloat.

• Thesaptankistoohigh,thereistoomuchpressureonthefloatbox.Movethetankorinstallapressurecontrolfloatbox.

Sap turns to syrup in the 1st syrup pan:

• Itcanhappenwhenyoustarttheevaporator.Draw-offenoughsyruptogetittothefrontanddistributewhatwasdrawn-offinthefluepan.Thiswillgetthemovementforwardgoing.

The heat in the chimney is too hot; the base stack turned red or the evaporator doesn’t boil much:

MAINTENANCE

Pan cleaning

1. Fillthepans(evenwiththeseparation)withpermeateorcleanwater.

3. Drainandrinsethoroughlyallthepanswithwater.Makesurethereisnotraceofacidleftinthepans.

4. Fillthepansagainandaddsodiumbicarbonatetoneutralizeanyacidresidue.Leavefor15minutes.Drainandrinsewithwateronelasttime.

5. Never use abrasive products, metal brushes, steel wool or any products with chlorine ormuriaticacid.
