Pre-Installation
Models: HC-9 thru HC-24 with DCCP Control
The Heavy Commercial steam generator (HC-9 thru HC-24)
comes from the factory assembled, carefully wired, and tested.
Please read all instructions before installing or servicing.
IMPORTANT:
1. All Plumbing and Electrical work must conform to
local and national codes.
2. All power must be OFF to the steam generator when
installing or servicing the unit.
3. Do not use or install unauthorized components,
accessories or products on the generator or its'
piping.
III. Pre-Installation:
The following general information should be used in conjunc-
tion with your architect, designer and contractor in providing a
suitable and safe steam room environment for the steam
bathers.
IMPORTANT:
Refer to the specification plate affixed to
the cabinet of the steam bath generator.
A) Insure that the model steam generator unit purchased is
sized adequately for your steam room.
B) Be sure to have the proper electrical supply. Determine
proper size of wire, voltage, amperage, and phase for the
steam generator based on the specification plate attached
to the generator and the chart in the back of this manual.
C) Provide an inline fuse/circuit breaker as required sized in
accordance with specification chart. Do not install a GFI
Ground Fault Interrupter to this equipment.
D) Select a location to install the generator to allow sufficient
room (See Access Area Requirements) for access to the
unit in the event service is required. Select a clean dry
indoor location protected from freezing. Do not store
flammable materials such as gasoline, thinners, paints,
etc. in the same area as the steam generator. Do not
store corrosive materials such as chlorine near the steam
generator.
E) Location of the steam generator should be placed where
the ambient temperature range is: 40ºF to 104ºF.
E) For safe low temperature draining (blow down) of the
steam generator it may be necessary to drain into an
ASME blow down tank. If required additional space for the
tank will be necessary. Consult with your architect or
licensed plumber. The blow down process can potentially
dump boiling water down the drain and damage the
drainage system.
F) The steam generator should be located as close as
possible to the steam room. If the steam generator is
more than ten feet from the steam head, insulate the
steam pipe with appropriate pipe insulation rated for a
minimum of 250ºF.
G) The serial number plate should be visible when installed.
H) The steam room must be completely sealed on all sides,
top and bottom. Floor, walls, and ceiling should be
completely covered with waterproof material such as tile.
Floor and bench materials must be slip resistant (see
Safety Guidelines).
I) Provide a floor drain inside the steam room for condensate
run-off and steam room cleaning.
J) Only water tight lighting fixtures approved for the applica-
tion should be used.
