Setting Sequence; Manifold Pack With Mecs Or Pams Staging (No Reticulation System); Manifold Pack Without Mecs Or Pams Staging (Reticulation System) - Rinnai MP2200 Operation & Installation Manual

Wall mounting or floor mounting is possible. If you are wall mounting the Manifold Pack then drill holes in the wall in
the desired location and mount the frame to the wall using suitable fixings. If you wish to floor mount the Manifold
Pack then you will require an appropriate DDBASE if the unit has been pre-supplied on a factory made skid base
you are not required to do anything. A DDBASE requires some minor assembly using the brackets and fixings
provided.
Manifold Packs used in buildings without a reticulation system will have a staging system either a Manifold Electronic
Control System (MECs) or Pressure Activated Manifold System (PAMs). MECs is a sophisticated electronic control
system that is supplied pre-wired except for joining the modules together. Refer to the separate MECs installation
booklet supplied for full details on how to connect each heater control. PAMs is a mechanical staging system
using a pressure sensitive valve installed on the cold supply riser to each heater except the first one. PAMs has
a maximum capacity of 6 heaters and needs to be setup on installation to operate correctly. Each valve needs to
have the pressure sensitive plunger set dependant on how many heaters are present.

MANIFOLD PACK WITH MECS OR PAMS STAGING (NO RETICULATION SYSTEM)

•
Turn on power to each heater via the GPO's
•
Open one or more outlets to generate water flow through the heaters. The outlet temperature should appear
in the maintenance monitor window on each heater. This is factory preset at 75° but can be adjusted if
required, refer to relevant temperature settings for heaters. This indicates the units are operational.
•
Not all Rinnai heaters will fire up as its flow rate dependent. To verify all heaters are operational either open
more outlets or, if this is not practical, close the cold water valve underneath the currently operating heaters
to restrict the flow. Other heaters should then fire up.
•
Clean all filters on completion
