STORAGE & MAINTENANCE INSTRUCTIONS
WARNING
RISK OF UNIT BURSTING.
DO NOT STORE / OPERATE
UNIT IN A FREEZING
ENVIRONMENT!
WINTERIZING:
1. For storage and transportation purposes in subfreezing ambient temperatures, it
will be necessary to winterize this unit. This unit must be protected to the lowest
incurred temperature for the following reasons:
a. If any part of the pumping system becomes frozen; excessive pressure may
build up in the unit which could cause the unit to burst resulting in possible
serious injury to the operator or bystanders.
b. The pumping system in this unit may be permanently damaged if frozen.
FREEZE DAMAGE IS NOT COVERED BY WARRANTY.
If you must store your unit in an area where the temperature may fall below
32°F,
you can protect your unit by following the procedure outlined below.
1. Gather the following items:
a. Two 5 gallon containers.
b. One gallon of antifreeze. (Use an environmentally safe antifreeze.)
c. Water supply.
d. Three foot hose, 1/2-3/4 I.D. with a 3/4 inch male garden hose fitting.
2. Procedure:
a. To start winterizing, unit must be run according to the "Start-up Cold Water
Operation" listed on page 18.
b. After running, shut off the unit and water supply.
c. Relieve system pressure by pointing the trigger gun in a safe direction and
squeezing the trigger until water flow ceases to exit the Dual Lance Assy.
d. Lock the trigger gun in the OFF position and adjust the Dual Lance to the low
pressure mode.
NOTE: Proper winterizing is based on the recommended manufacturer's instructions
listed on the "Protection Chart" shown on the back label of most antifreeze
containers.
e. Remove lid from float tank.
f Start the unit and squeeze the trigger gun until the float tank is almost
empty.
g. Stop the unit.
h. Mix antifreeze and water in a container that can be used for pouring the solution
into the float tank.
i. Start the unit. Point the trigger gun into the empty container. Trigger the
gun until the antifreeze begins to exit the trigger gun. Continue cycling the
trigger gun several times until all the antifreeze mixture is siphoned from the
container.
j. Stop the unit.
k. Disconnect the hose and trigger gun from the unit and drain any excess
antifreeze back into the 5 gallon container.
l. Drain hose, trigger gun and dual lance assembly and store with the unit in a
safe non-freezing area.
m. Store antifreeze solution for next use or dispose of according to state EPA
laws.
3. OPTIONAL PROCEDURE:
a. Shut the unit and water supply off.
b. Relieve system pressure by pointing the trigger gun in a safe direction and
squeezing the trigger until water flow ceases to exit the nozzle.
c. Disconnect and drain the hose, trigger gun and dual lance assembly.
d. Remove the coil drain plug from the heat exchanger inlet.
e. Start the unit and allow it to run until all the water exits the unit. Once the water
has stopped flowing from the unit, turn off.
NOTE: When using this procedure, use caution as ice chips can form from drops of water
which could cause the unit to burst if starting before completely thawed.
