Oakite No. 32 is an acid. Be sure that the acid is slowly added to the water. DO NOT PUT
WATER INTO THE ACID - this will cause spattering and excessive heat.
Wear rubber gloves and wash the solution from the skin immediately if accidental contact
occurs. Do not allow the solution to splash onto concrete.
Always turn OFF the unit circuit breakers (CB-1 & CB-2) and disconnect main power supply
before working on moving parts.
Installation requires wiring to the main unit circuit breaker, CB1. Make sure the power to the
unit is off and power plug disconnected before beginning installation.
Charge water-cooled condenser or receiver according to nameplate specifications to ensure
optimal unit performance.
Do not remove wire harnesses from controller modules unless you are grounded to the unit
frame with a static safe wrist strap.
Unplug all controller module wire harness connectors before performing arc welding on any
part of the container.
Do not attempt to use an ML2i PC card in an ML3 equipped unit. The PC cards are physically
different and will result in damage to the controller.
Pre-trip inspection should not be performed with critical temperature cargoes in the container.
When Pre-Trip key is pressed, economy, dehumidification and bulb mode will be deactivated.
At the completion of Pre-Trip activity, economy, dehumidification and bulb mode must be reac-
tivated.
When condenser water flow is below 11 lpm (3 gpm) or when water-cooled operation is not in
use, the CFS switch MUST be set to position "1" or the unit will not operate properly.
