WhisperGen PPS16 Installation and Commissioning Manual Rev: 080801

Coolant
The primary circuit coolant must contain a corrosion inhibitor because the engine is largely
manufactured from aluminium alloy.
If ethylene glycol is used as the corrosion inhibitor, a minimum of 35% undiluted glycol to 65%
fresh water solution shall be used.
It is essential that the primary coolant is clean and free fro debris. Foreign particles can obstruct
internal coolant passages and damage the WhisperGen. Contaminated circuits should be fitted
with sludge traps, upstream of the WhisperGen.
Potable water only should be used in the primary circuit to cool the WhisperGen. A corrosion
inhibitor must be added.
APPENDIX B: Battery specification
A deep-cycle lead acid or gel battery with a minimum capacity of 200 ampere hours at 12V or
24V shall be used.
The battery cable size shall be a minimum of 35mm
²
.
The maximum run length for the battery cable shall be:
●
4 metres for a 12V system; and
●
8 metres for a 24V system.
If longer battery cables are required they shall be proportionally larger in size. For example, for 8
metre cables for a 12 volt system, the cable size shall be a minimum of 70mm
².
