MAINTENANCE 4
CAUTION
To prevent ignition of hazardous atmospheres,
1. Any repairs internal to the flameproof enclosure must be made
by the manufacturer.
2. Keep flameproof enclosure tight, torque to 40.6 Nm (30 ft. lbs.)
while in service and disconnect power before installing or
removing vaporizer from service.
GENERAL
The ZIMMER vaporizer is designed for long-term trouble-free
operation. Because of the nature of its use, and the severe duty it
receives, it is important to provide scheduled maintenance. The
maintenance schedule, type, and frequency provided in this manual
is the minimum maintenance required for proper operation of the
vaporizer. Ambient conditions surrounding the vaporizer installation
and LPG quality may require a more frequent maintenance
schedule. A list of REPLACEMENT PARTS is in Section 6 of this
manual.
Initial Installation & Operation Inspections:
Required 30-60 days after initial installation
Inspect strainer and remove accumulated debris. Note: if debris
accumulation is heavy check every 3 - 6 months.
and connections
Check junction/terminal box electrical connections. Inspect
electrical connections for loose conductors and any indication of
and drip legs
Check all drip legs and vaporizer for heavy ends and oil build-up. If
present, first ensure there are no sources of ignition within 25 feet (8
meters), then drain heavy ends. NOTE: In areas where LPG quality
is poor it may be necessary for the drip legs and the heat exchanger
to be checked for heavy ends more frequently (monthly or bi-
monthly depending on LPG quality). Once it is verified that no
significant quantity of heavy ends is accumulating during vaporizer
operation, this maintenance can be performed on an annual basis.
