Table 3: Defrosting flowchart
If plugged in, use Button F4 to turn System Switch OFF. Unplug from AC power.
Unload all temperature-sensitive products.
Warm the Cold Plates; choose method below based on ambient temperature.
Ambient Temperature Above 40°F
Open all doors to the refrigerated
compartment.
Position a fan to blow warm air over the
Cold Plates.
Warm water (110°F maximum) may be
sprayed on the Cold Plates with a garden
hose or similar equipment.
Do not pressure-wash.
Do not use steam cleaning.
Do not spray water directly at interior lights
or other electrical equipment.
Ambient Temperature Below 40°F
Consider moving the truck to a heated garage to use
“Above 40°F” method.
If the truck type is compatible with a loading dock, a
warm loading dock could allow use of “Above 40°F”
method. (Only open the rear door)
If Defrosting must be done below 40°F
Place a portable electric heater in the refrigerated
compartment or direct a portable ducted heater into
the refrigerated compartment. Keep the doors shut as
much as possible.
Any heater must be thermostatically limited to 100°F
maximum.
Heater must be protected from (or unaffected by)
dripping water from Cold Plates and melt water
pooling on the floor.
Do not use a fuel-burning heater which vents
combustion gases into the refrigerated compartment.
Frost accumulation is much less during the cold
season, so defrosting should be needed much less
frequently than during summer.
When Cold Plates are defrosted, wash floor and shelving (if equipped). Any wet cleaning or sanitizing
should be done at this time.
Dry the refrigerated compartment and Cold Plates with a fan.
After defrosting, the solution in the Cold Plates will likely be completely thawed. See Section 3.3 for
Pre-Cooling the Cold Plates to make the truck ready for refrigerated use.
Consider if the system is due for a routine Cold Plate Check. See Maintenance Schedule (Table 5) and
Section 5.3
