Rittling PR1 Installation Operation & Maintenance

Installation Instructions:

1. Radiators are boxed together in as few crates as
possible. A box of brackets is included as a separate
piece, and it is marked to denote brackets. Inside the
crates, each panel is wrapped
in foam sheeting. Saving this
foam to re-wrap the panel
once it is wall mounted will
protect it from construction
site damage.
2. Each radiator is tagged with
a label that indicates the
project name, model type,
color, connection code, bracket type & quantity and
tag number. Locate each radiator as required.
3. Carefully place each radiator face down on a smooth
level surface (i.e. floor or table). Distribute the brackets
for each radiator. The tag on the radiator indicates the
quantity of brackets. Mount the brackets securely on
wall studs or solid backing with two lag bolts, spacing
them as evenly as possible at 2' to 4' apart, with a
bracket at least 12" from each end of the panel. Allow
a minimum of 3" below each panel radiator to facilitate
cleaning and to assure proper output. For baseboard
models, 1" above the floor is permissible with little
loss of heat output.

RITTLING RADIATORS
Horizontal Units
Installation, Operation & Maintenance
Radiators with Fins on back side of panel (PRF &
PR3F): With the radiator face down, attach each PR
CLIP to the fins at the stud location. With the radiator
still face down, thread the leveling bolts (5/16"
carriage bolts) into the
bottom threaded positions
with a crescent wrench.
Once the bolts have cleared
the paint away, they should
turn easily by hand. Hang
the panel (installed on wall
in step 3) onto the brackets
to determine if the leveling
bolts are properly adjusted.
Check that the panel is
level.
Radiators without Fins on back side of panel (PR,
PR2 & PR2F): With the radiator face down, thread
the leveling bolts (5/16" carriage bolts) into the bottom
threaded positions with a crescent wrench. Once the
bolts have cleared the paint away, they should turn
easily by hand. Hang the panel onto the brackets
(installed on wall in step 3) to determine if the leveling
bolts are properly adjusted. Check that the panel is
level.
Remove the radiator from the wall and thread the
supply and return fittings into the connections on the
radiator. The sealing tape or pipe dope used is the
installer's choice – make sure the connections are leak
tight. One quarter of a turn past hand tight is usually
sufficient. Each radiator needs to be fitted with a 1/8"
air vent prior to startup.
