5 Startup and Operation
5-1 Introduction
The checklist below outlines start-up procedures for Economical Series water
temperature control units. This list assumes that installation information located in this
manual has been read and followed.
5-2 Startup Checklist
; Check the shipping papers against the serial tag to make sure
that system size, type, and voltage is correct for the process
under control.
; Check the transformer primary voltage connections to be sure
they are configured for the electrical power you are using. The
voltage at the main power connection must be within plus or
minus ten percent (±10%) of the voltage listed on the serial tag.
Electrical connections must conform to all applicable codes.
Make sure that a qualified electrician checks all electrical
connections.
; The safety thermostat is preset at the factory to 250ºF or 300ºF
(121ºC or 149ºC), depending on configuration. It trips at 265ºF
or 315ºF (129ºC or 157ºC), depending on configuration.
; The relief valve should be piped to an open, unrestricted drain.
;
TO PROCESS , FROM PROCESS , WATER IN , WATER OUT ,
and MOLD PURGE connections should be complete.
!
CAUTION
Only use components rated at a minimum of
150 psig and 250
°F (1,034.25 kPa/10.34 bars and 121ºC).
; All outer panels must be in place.
; All external process valving should be set for proper operation
of the unit.
; Cooling and/or makeup water between 16 psig and 55 psig
(110.32 kPa/1.1 bars and 379.2 kPa/3.79 bars) must be
available for the unit to operate properly.
