2.28 OPERATION IN WET CLIMATE.
The following procedures should be observed when operating CBPS in a wet climate:
a. If heavy rain is expected or if system will be set up for a long period of time, cab crew digs a trench
around outside of ABS between edge of ground cloth and stakes to divert runoff water away from
ABS, except under DCS doorways.
b. Dry all ABS components before repacking.
The following should be observed when operating CBPS under extremely cold conditions (-25F):
Operating ECU in HEAT mode prior to warm-up will shorten the life of main hydraulic
pump and drive belt.
ECU should not be run in HEAT mode until ECV engine has run for at least 15 minutes so
hydraulic oil temperature can warm up.
REPLACE FILTER indicator on rear control panel may light during cold weather operation.
Do not change NBC filter element unless indicator stays on after system has warmed up for
at least 15 minutes.
Ensure side, ceiling, ECV end and ambulatory airlock end insulation panels are securely
installed and all fastener hook and fastener loop tape closures are fastened to minimize heat
loss. Adjust as required.
When operating in internal power mode, 10 kW TQG can be used for supplemental heating.
a. Cab Crew Tasks
