General
These heaters are designed for indoor chain mounting or
cart mounting. Not for recess installation. Elements may be
installed prior to mounting unit.
DO NOT USE IN OUTDOOR LOCATIONS
Mounting Limitation– (Suspension Mount) Observe all
minimum dimensions from ceiling, walls, floor and com-
bustible material.
Maintain minimum clearances of:
– 24” (610mm) to vertical wall surfaces
– 24” (610mm) to ceiling
– 72” (1829mm) to floor
When heater is mounted the minimum distance to the wall,
do not angle the heater toward the wall.
Installation of Quartz
Tube Elements
1. Remove terminal cover at each end of fixture
and wire guard to gain access to terminal blocks.
2. Remove element from wrapping.
NOTE: Do not handle quartz element with bare
hands, or with gloves or rags that may have grease
on them.
3. Remove #10 hex nut, lockwasher and flat washer from
terminal stud. Insert element ring terminal to terminal
stud on top of cup washer (brass). Replace flat washer,
lockwasher and hex nut. Tighten nut. Refer to figure 1.
4. Replace terminal covers and wire guard .
Chain Mounting (Indoor Only)
1. Attach “S” hook to both ends of each chain.
2. Attach chain links to ceiling accordingly, to achieve
desired mounting height.
3. Attach “S” hook to 4 bolts protruding from back of
heater. Secure hooks with washer and nut as shown in
Figure 2.
4. Plug heater power supply cord into 120 volt 3 wire out-
let for Model RR22012. Plug heater power supply cord
into 240 volt 3 wire outlet for Model RR35724. The
power cord is equipped with a 3 wire grounded plug
and must be inserted into a matching receptacle. (see
warnings 1,2,3,&4)
5. Place both ON-OFF switches in ON position for maxi-
mum wattage. For reduced wattage, turn one ON-OFF
switch to the OFF position
.
Cart Mounting
NOTE: UL Listing does not cover cart mounting of
heater.
1. Mount the upper cross bar to the cart at approximately
42” from the floor. Attach one clamping bracket to the
cross bar by inserting the “T-hinge” into the slot on the
cross bar and rotating the clamping bracket 90º.
Secure the bracket using the bolt, washer and nut pro-
vided. See Figure 3. Check that the cross bar is cen-
tered on the cart and install the second clamping
bracket to the other side such that the cross bar is
level.
2. Locate the lower cross bar about 9” below the top cross
bar for the two element heater (allow 16” for the four
element heater). Clamp it to the cart using the same
procedure as in step 1 above. Just hand tighten the
nuts to the mounting bolts such that the cross bar is
loose enough for aligning adjustments in step 4 below.
3. Mount the heater to the upper cross bar using two of
the four bolts on the heater housing. The heater must
be mounted and operated horizontally to ensure proper
operation of the infrared elements. Operating the
heater with the elements vertical will cause premature
failure of the elements.
4. Mount the heater to the lower cross bar by using the
remaining two bolts mounted on the heater housing. It
may be necessary to reposition the lower cross bar to
align the holes.
5. Tighten the two lower clamping brackets fully and
check that all fasteners are tight.
Mounting Limitation-(Cart Mount) Observe all minimum
dimensions from ceiling, walls, floor and combustible mate-
rial.
