The WATERWORKS Steam Generator can be hung on a wall or set on it’s base. The best mounting location
will satisfy all or most of the following conditions:
1. The steam line should slope to allow condensation to drain into the steam room.
2. The steam line should be less than 20 ft (6m) long; 10 ft (3m) is preferred. Steam lines over 20 ft (6m) long should be insulated.
3. The mounting location should minimize the number of bends and elbows in the steam line.
4. The steam line should enter the room 18” (460 mm) above the floor or at least 12” (305 mm)above a tub rim or ledge.
5
. No steam head shall be more than 30 inches (760 mm) above the floor.
6. The steam outlet should be located to avoid potential user contact.
7. The steamers should be installed in a dry, well ventilated area. The space provided should be at least:
7 cu ft (0,2m
3
) for one steamer or 17 cu ft (0,5m
3
)for two steamers or 27 cu ft (0,8m
3
) for three.
Suggested locations are under a vanity or in a closet, attic, crawl space or basement. Note:
The steamer must be in an area protected from freezing
.
8. The slave steamers should be installed within a 25 ft (7,6m) cable length of the primary steamer and the secondary steamer(s) should be within a 25 ft (7,6m)
cable length of the control installation.
Note:
Longer control and slave cables are available; contact Service at 1-800-927-2120, Ext 3 for assistance
. The installation
should provide clearance for service and element removal. See diagram 3.
10. The mounting location should allow for a drain hookup. There should be no more than three 90° bends and 10 ft (3m) of pipe between any steamer’s drain
outlet and its drain valve inlet. See diagram
15
.
11.
Refer to the mounting instructions in WATERWORKS installation instructions document 4211-1661 for details regarding mounting individual steamers.
SECTION 2: SELECT MOUNTING LOCATION (continued)
IMPORTANT
Before deciding on a mounting location,
please read through these installation
instructions completely and take a careful
look at al of the diagrams.
An exhaust fan installed outside the
steam room is strongly recommended
in order to remove excess steam
from the steambath or shower area
It is strongly recommended that no exhaust
fan be installed inside the steam room. Doing
so will result in a loss of heat and steam
through the exhaust fan and port.
Insulate all steam lines and drain lines
within the enclosed space.
Each steamer must be provided with
at least six (6) inches for wiring
access at the control wiring end.
Each steamer must be provided with at least fifte
en
(15) inches clearance at
the pipe end.
There should be at least thirty-six (36) inches
in front of the louvered cover at
each steamer for service access.

WARNING
! Do not put a shut-off valve in the steam line!
The line must be unrestricted from the steamer into the steam room !
To reduce the risk of explosion, do not interconnect steam outlets!
• Do not mount outdoors.
• Protect from freezing.
• Unit must be located so as to allow access for service.
• The steam steamer will not operate properly unless it is mounted level with the arrows pointed up.
• A separate line must be provided or each steam outlet.
• Avoid traps and valleys where water could collect and cause a steam blockage.|
• The hot steam must be insulated against user contact. Install the steam head so as to avoid potential
user contact.
• Do not install the steam head near benches or where condensation will drip on the user or puddle as
this will present a scald hazard.
• The pressure relief valve must be installed in manner that reduces the risk of scalding.
• Do Not drain the pressure valve or steamer into the steam room!
• Draining the pressure relief valve into the steam room may present a scald hazard!
Refer to the following diagrams for some suggested systems (and some not allowable steam pipings).
