SAFETY GUIDELINES

Operator must be properly trained prior to operating the HPU.

HPU power switch must be in "Off" position when connecting or disconnecting hoses to the aircraft.

Bypass valve must be in the "Open" position when starting or stopping the HPU.

Electrical power must be disconnected from the HPU and the bypass valve must be in the "Open" position before
servicing the HPU. (Reference Technical Manual for details on servicing the HPU.)
2.7
GENERAL COMMENT
The HPU is intended to be operated by personnel trained in the proper use in conjunction with the aircraft maintenance
manual.
The HPU must be used in accordance with the Technical and Operator Manuals and the intended aircraft.
3.0 PREPARATION PRIOR TO FIRST USE
3.1 GENERAL
Prior to operating the HPU, the user should become familiar with this Operator Manual.
3.2
SERVICING RESERVOIR
Fill the reservoir with the correct fluid (see label next to reservoir fill for correct type of fluid) until fluid level is above the
minimum fluid level mark but below the maximum fluid level. See
Figure 5.3.1 Front Panel Controls for reservoir fill location.
3.3
CONNECTING ELECTRICAL LEADS
Electrical Shock! Never touch electrical wires or components while electrical power is attached. Only qualified
electricians should connect the electrical leads.
Install plug onto the electrical cord. If motor rotation is not correct, change any two of the three leads at the plug.
Reference 11.0 Electrical Power and Protection Requirements for power requirements and fuse sizes . (See 5.4
Start up Procedures before starting HPU.)
WARNING!
Balanced three phase voltage must be available to prevent overheating and damage to the motor.
Voltage unbalanced between phases occurs when the voltages differ from one another.
Some reasons for imbalance are:
1. Unequal loading of each phase
2. Poor connections in the supply
3. Single phase condition caused by blown fuses or bad connections
If these conditions occur in the incoming power system, a protective devise, such as a voltage monitor,
should be installed on the machine to prevent motor damage.
4.0 TRAINING
4.1 TRAINING REQUIREMENTS
The employer of the operator is responsible for providing a training program sufficient for the safe operation of the HPU.
4.2 TRAINING PROGRAM
The employer provided operator training program should cover safety procedures concerning use of the HPU in and around
the intended aircraft at the intended aircraft servicing location.
4.3 OPERATOR TRAINING
The operator training should provide the required training for safe operation of the HPU.
NOTE: Maintenance and Trouble Shooting are to be performed by a skilled and trained technician.
