Section 4: Bracket Installation Instructions
Type 11 – L Bracket Installation
Step 1: L Brackets can be installed using the thin or wide width of the wall bracket. Job site preference will dictate which installation will work best.
Units should be installed at least 4″ above the floor for proper operation. Measure required distance for bracket installation using the brackets on the back side of the panel radiator as a guide. It is recommended to install the brackets on a stud, if one is not available, wall anchors have been provided.
The brackets are identical, no left or right. The U notches on the top and bottom of the brackets face up (refer to Figure 2 page 2). These notches are where the unit will rest.
Figure 4 – Locking Clip and U clip Installed
Figure 5 – Top Locking Clip Installed
Step 2: Insert white plastic anti-vibration locking clip into notch at the top of the wall bracket until it clicks (see Figure 5). Insert the small square plastic U clip into the bottom notch of the wall bracket until it clicks (see Figure 6). See Figure 4 for proper placement of top and bottom clips.
Step 3: Install the wall brackets using the wall anchors (when a stud is not available) and bolts supplied with the unit.
Step 4: Install the panel radiator onto the installed wall bracket. Align the bottom U clip with the bottom bracket on the unit, while also aligning the top locking clip with the top mounting bracket on the unit. Push the unit down onto the bracket until the unit locks into place on the top mounting clip. LOCKING CLIP MUST LOCK OVER THE TOP OF THE MOUNTING BRACKET TO HOLD THE UNIT SECURELY TO THE WALL (see Figure 7 for reference only, unit not installed on wall).

Figure 7 – Final Assembly for illustration purposes not installed on wall
Types 21, 22 & 33 J Bracket Installation Instructions
Step 1: Wall brackets should be installed on wall joists whenever possible. Mount the brackets on the wall using the bolts and wall anchors provided. The unit should be mounted at least 4″ off the floor. The brackets should be installed 4 ¾” in from the edge of the unit on each side. For units over 70″ a 3rd bracket is required to be installed. The 3rd bracket should be installed in the center of the unit.
Step 2: Set the unit on the brackets. The bracket height adjustments can be made by pushing in the tab on the plastic slide adjuster (see Figure 8). To adjust the depth of the bracket (adjusts from 1 5/16″ to 2 1/8″), loosen the screw at the top of the bracket to slide the hanger forward or back (see Figure 9). Be sure to set the edge of the back panel into one of the notches in the bottom of the bracket to insure the unit is stable (see Figure 11). Tighten the screw at the top of the bracket to secure the unit in place (See Figure 10).

Section 5: Piping
NOTE: OXYGEN PENETRATION IN THE INSTALLATION NEEDS TO BE AVOIDED IN ORDER TO PREVENT INTERNAL CORROSION OF THE RADIATORS. THESE UNITS MUST BE INSTALLED IN CLOSED LOOP INSTALLATIONS. FAILURE TO DO SO WILL VOID THE WARRANTY.
Check that the unit is firmly in place. Piping to the unit can be done using copper or pex pipe.
Choose a piping arrangement that is suitable for the job. If using 3/4″ arrangement, it is highly recommended a 12″ allowance of 1/2″ piping prior to converting to 3/4″. The unit has 6 possible connection points. Two on each side and a bottom connection that can be installed on either the left hand or right hand side as the units are reversible (for all units except the Type 11). Type 11 has right hand connections only. The unit is not reversible. If piping from the bottom, remove the metal covers and the o-rings (see Fig 12). Failure to remove the o-ring will prohibit proper installation of accessories and may cause leaking.
For a bottom piping arrangement, the supply is to the inside of the unit, and the return to the outside (see Fig 13). Should the unit get installed with the incorrect piping arrangement, valves (part # 1016362) are available to reverse the piping with little disruption.
The unit was supplied with 2 blind stops (drain plugs), an air vent, and a thermostatic valve insert and cover.
For bottom piping arrangements, remove the temporary plugs from the left and right hand side lower ports and install the chrome drain plugs. The thermostatic valve and insert must be installed on the same side as the supply and return port located at the bottom of the unit. If piping is on the bottom left hand side, the thermostatic valve and insert must be installed on the top left hand port.
Failure to install correctly will result in noise. Once the insert is installed, a thermostatic head may be installed. If a thermostatic head will not be installed, cover the insert with the white plastic cover supplied with unit. The air vent should be installed on the upper corner opposite the valve insert. See Figure 14 for recommended placement of accessories for bottom piped units.
Once all the connections have been made, the air must be purged from the system. This can be accomplished using the coin air vent that was supplied with the unit.

Thermostatic Valve Settings
The thermostats purchased through Mestek have multiple settings. Refer to the chart below for set points in relation to the number on the valve. The snowflake setting is a low flow / non-freeze setting. This will allow a small amount of water flow to prevent the unit from freezing. If the thermostat is set at 0, no water will flow and the unit will be off. Refer to Figure 16 for the temperature ratings.
