1.5 Excessive Supply Pressure Caution
Models: DA, DB, DC, DD, DE, DF, DG, DH, DJ, DK, DL, DM
A water supply of 60 PSI (414 kPa) is required to operate these systems at 300
o F (149 o C). Mokon
suggests an optional pressure regulator on Mokon temperature control systems for applications
with high supply water pressure (exceeding 75 PSI/ 517 kPa) to reduce or eliminate the potential
for water hammer. Water hammer in the Mokon temperature control system or the process and
cooling lines can lead to system damage and reduced system life. If a pressure regulator is added
to the Mokon temperature control system, it must be of the design that incorporates a bleed off for
thermal expansion of the fluid.
1.6 Overhead Piping Warning
When overhead piping is connected to a Mokon temperature control system equipped with an open
reservoir or non-pressurized expansion tank there is risk of overflow of the system’s reservoir tank
upon shutdown, this is due to the back flow of fluid volume from the overhead piping system.
To prevent reservoir tank overflow an overhead piping kit should be installed. This kit is available
from Mokon as an option.
1.7 Short Circuit Current Rating Caution
Equipment supplied with a safety door disconnect is design rated for a short circuit current rating
(SCCR) of 5,000 amperes RMS if protected with a class "RK5" fuse and, equipment supplied with a
power cord is design rated for a short circuit current rating (SCCR) of 10,000 amperes RMS if
protected with a class "J" fuse.
1.8 No Flow Warning
It should be noted that if any external valves are installed in the process flow path, they must be
opened before starting the Mokon temperature control system or risk causing serious damage to
the system and the process.
Fluid must be established (flowing) through the Mokon temperature control system in order for the
safety features to work properly and adequately protect the Mokon temperature control system.
The use of valves downstream of the Mokon temperature control system are not recommended as
they could potentially render the system safeties inoperative if closed. This could cause serious
system damage and would void the warranty. To avoid disabling the standard safety features,
please contact Mokon to discuss optional safety features that may be required to adequately
protect the assembly.
1.9 Non-Potable Water System
This system has been designed for use in non-potable water applications only. For applications
requiring potable water use please contact Mokon directly to discuss a product offering.
