Storage
Materials list:
1) Two 5 gallon buckets
2) 4-5 foot long garden hose or equivalent (recommend 5/8" to ¾" diameter
with male ¾" Garden hose threads on one end)
Procedure:
1) In a 5 gallon pour at least 2 gallons of environmentally safe antifreeze.
Note: whether using undiluted or pre-diluted antifreeze, follow
manufactures mixing guidelines to ensure proper freeze protection.
2) Elevate bucket so it is higher than the unloader.
3) Connect a 4-5 foot long garden hose or equivalent to inlet connection.
4) To ensure good priming fill hose with water or antifreeze mix before
placing end into 5 gallon bucket of antifreeze.
5) With the nozzle removed, trigger gun off, and with burner off point trigger
gun into a second empty 5 gallon bucket and start the unit.
6)
With unit running, spay into the empty bucket for several seconds
release trigger for 2 seconds. Continue cycling the trigger gun multiple
times until all the antifreeze has be drawn from the supply bucket. Note: if
system was completely flushed you should see antifreeze in the spray
bucket. We recommend lowering the engine rpm to ½ or 1/4 throttle during
this step to help assist in priming.
7) With unit shut off, remove hoses and drain excess antifreeze into spray
bucket.
8) Properly dispose of antifreeze according state EPA laws.
