Clean with DeoxIT® Gold GN5 or replace as appropri-
ate.
CAUTION: Some of the electrical connectors have
thin precious metal plating. DO NOT scrape corro-
sion from contacts with a hard sharp object. DO
NOT use abrasives, petroleum distillates, silicone
based cleaners, erasers, combust able chemicals,
or any other harsh cleaners. Hollis recommends the
use of DeoxIT Gold® GN5 for cleaning the electrical
contacts of the BATTERY CABLE ASSEMBLY (8)
and BULKHEAD CONNECTOR (7).
NOTE: It is not necessary to remove the PRES-
SURE RELIEF VALVE (13) during regular service.
It may simply be rinsed with water. It is designed
to relieve internal pressure, due to failure of other
components. If it is bubbling, refer to the Trouble-
shooting sections for the Oxygen Solenoid and
Routing Board for the most probable cause. Un-
less removing it to replace due to bad corrosion
or an actual failure, skip step 8.
9. Turning counter clockwise with a driver and 12 mm
socket, remove the
PRESSURE RELIEF VALVE (13)
(FIG. 5).
Discard it.
NOTE: The OVER-PRESSURE PLUG (2) at the bot-
tom of the HOUSING (1) is not a wear item. DO
NOT replace unless over-pressure has occurred,
blowing it out of its port.
