QUANTUM DI HEATER OPERATION / MAINTENANCE MANUAL
Recommendation: Either insulate the hot DI water process line or
place a Hot Surface hazard warning (example shown below) on the
tubing every 20 feet. Conform to local codes while evaluating hot
water line routing.
Caution
Hot Surface
Do not touch. Can cause
skin burns upon contact.
Disconnect and lockout
power and allow surface to
cool before servicing.
Connect the “Over Pressure Relief Drain” to an open drain line with
no more than 30’ of ¾” tubing. Do not connect restrictive fittings or
valves in line with the drain. If an overpressure condition occurs in
the heater, a burst fitting will relieve pressure in the heater. The fitting
must be replaced (see Section 7.1.g).
Attach cabinet drain line to bottom of cabinet. If a cabinet drain line is
not installed, the system will be difficult to drain should repairs be
needed.
CAUTION:
Depending on installation and routing of water supply
lines, a trip hazard may be created. It is the responsibility of the facility
installation personnel to eliminate or minimize any and all trip hazards or
identify such hazards with visual warning signs.
Lockout
and
Tagout
facility power connection switch or equivalent
before installing system.
Open the front door by rotating the electrical disconnect handle to the
OFF position and then rotate the door handle. This will allow access
to the electrical connections.
Route the wires from the electrical source (480 VAC, 415VAC, 380
VAC, or 208 VAC 3-phase) into and through the conduit opening on
the top of the enclosure. To secure an electrical conduit fitting,
remove lifting eyebolts located on top of the system and raise the
vented top panel. The conduit nut may then be secured. Reassemble
the vented top panel to the enclosure.
