Q17: What is the "maximum current draw"* from the ZIMMER
and under what
conditions does this occur?
A17: The maximum current occurs at the maximum capacity, the lowest temperature, and the
lowest voltage. The maximum power output occurs at the same conditions, except additionally
at the highest voltage. Please see electrical table in Appendix.
* Maximum current draw is defined as anything after the first five seconds preceding a
cold start.
Q18: Can the ZIMMER be used with DC voltage?
A18: Yes, the ZIMMER can be used with both AC and DC voltage. All respective Electrical
specifications such as breaker type and sizing remain the same.
Q19: What is the outer shell material, and is it “hot to the touch”?
A19: The outer shell material is made from anodized aluminum. Under normal operating
conditions, the shell should be safe to touch. However, in idle conditions and depending on
your installation, it may be too hot to touch. Depending on your installation, you may want to
consider mounting in a way to reduce risk of touching the vaporizer on idle.
Q20: Are common spare parts the same as the first- generation ZIMMER?
A20: The ZIMMER requires very few spare parts. Of those required, some are common
between ZIMMER revisions however some are not. Most notably, the inlet valve is different
between ZIMMER families and are ordered under separate part numbers.
Q21: Why do I require special circuit breakers for ZIMMER vaporizers?
A21: Because of the high initial current of the ZIMMER, Type D or TYPE J breakers are
required. Please see electrical specifications in the Appendix.
Q22: Can multiple ZIMMER vaporizers be installed together? If so, do they require
balancing orifices?
A22: Multiple ZIMMER vaporizers can be installed in parallel. Due to the self-balancing
nature of the ZIMMER, no balancing orifices are required. Additionally, you can parallel install
ZIMMER vaporizers of different sizes, again without the need for balancing orifices.
Q23: Can first generation and second-generation ZIMMER vaporizers be used
together? If so, do they require balancing orifices?
A23: First and second-generation ZIMMER vaporizers can be installed together in parallel,
again without the need for balancing orifices. Note: The system start-up time is based upon
the first-generation ZIMMER.
Q24: Can a propane version of the ZIMMER be converted to an LPG model?
A24: Yes, with replacement of the inlet valve. If using the wrong valve, you may experience
capacity de-rate or passing liquid. Contact the factory for the correct inlet valve for your
application.
Q25: What is the start-up time for the ZIMMER?
A25: The ZIMMER is ready to flow LPG within one minute.
