Blowing Sand and Dust

Sand and dust tend to damage moving parts and accumulate on the refrigeration coils, particularly the

condenser (outside) coil. Clean the coil surfaces regularly with water and remove accumulations of sand

and dust by blowing compressed air over them. Also, avoid opening and closing the container door more

than necessary.

During short periods of high levels of airborne sand or dust, the ADR-300 may be shut down and the RU

covered to reduce the amount of sand and dust drawn into the RU. If this is done, shut down the unit

before covering the RU and carefully monitor the container interior temperature to be sure it remains at

safe levels for the stored cargo.

Heavy Rain

Heavy rain should not adversely affect the operation of the ADR-300. The user should monitor the door

seal to insure that no leakage occurs.

Snow

Accumulations of snow or ice around the condenser air inlet or outlet may reduce the air flow through the

coil and degrade the RU performance. Keep these openings as clear as possible to promote good air

flow.

NOTE

Do not permit more than 12 inches of snow to accumulate on the

container roof.

Accumulations of snow elsewhere on or around the unit should not affect the ADR-300 performance.

Users are advised to keep controls, displays and gauges clear of snow accumulation to make routine

ADR-300 operation and monitoring easier.

Salt / Salt Fog

Salt and marine environments may leave a salt film on the surfaces of the IC and RU. This film can be

highly corrosive and should be removed by washing the system regularly. Wash unit as described in WP

0014 00 whenever a salt film is observed.

EMERGENCY PROCEDURES

General

With two exceptions, the ADR-300 will not normally pose a danger to personnel, resulting in an

emergency situation. The exceptions are:

One or more individuals being locked inside the container, either with the RU running or not. Personnel

trapped inside the container may suffocate due to lack of fresh air or may suffer hypothermia (low body

temperature) if exposed to low interior temperatures.
