INSTALLATION INSTRUCTIONS:: Elbow Heater |
Detailed Installation Instructions for UltraHeat® Elbow Heaters
Outside temperature must be at least 50°F (10°C) when applying tank, pipe and elbow heaters.
Please read the entire installation instructions before attempting to install the UltraHeat® Elbow Heater.
Caution: UltraHeat® Elbow Heaters can only be installed on rigid/hard plastic pipes.
1. Prepare the Elbow or Pipe Surface.
- Pre-clean the dust, dirt and other foreign matter from the elbow or pipe surface
using soap and water. Rinse with clean water and let the pipe surfaces dry completely.
- Next clean the elbow or pipe surface using isopropyl alcohol
(70% alcohol minimum) and a clean cloth or rag. Allow the elbow or pipe surface to
dry completely. The surface must be clean and dry before proceeding to the next step.
Caution: Do not use any type of solvent to clean the elbow or pipe surfaces.
2. Put the Elbow Heater onto the Elbow or Pipe Surface.
- Peel the release paper off the back side of the elbow heater exposing the
adhesive side of the pipe heater.
- For Elbows: Place the elbow heater onto the elbow surface with the
adhesive side against the elbow. Start by placing the center of elbow heater on the
middle of the outside curve of the elbow so that the ends of the elbow heater are perpendicular
to the flow of water through the elbow. Wrap the end of the elbow heater without the wires
around the elbow so it is on the inside curve of the elbow. Next wrap the end of the elbow
heater with the wires around the elbow so that it overlaps the other end. Firmly press the elbow
heater down so that the entire elbow heater makes contact with the elbow's surface. Be careful
not to stretch the elbow heater beyond its original size.
- For Drain Pipes (3 to +11 inches/7.62 to +27.94 cm): Start by placing the center of the elbow heater
on the bottom of the drain pipe so that the ends of the elbow heater are
perpendicular with the length of the pipe section. Wrap the ends of the elbow heater
up towards the top of the drain pipe, one side at a time, starting with the end without wires.
The ends of the elbow heater will slightly overlap. Firmly press the elbow heater down so that
the entire elbow heater makes contact with the pipe surface. Be careful not to stretch the elbow
heater beyond its original size.
- For Fresh Water Supply Pipes(12''(30.48 cm) or Less): The EH-158 Elbow Heater is the only
UltraHeat® Elbow Heater recommended to protect ½" fresh water supply pipe at lengths of 12"(30.48 cm) or less.
Start by placing the center of EH-158 Elbow Heater on the fresh water supply pipe so that
the long edges of the elbow heater will align with the length of the pipe. Wrap the long
edges of the elbow heater around the fresh water supply pipe, one side at a time. The long edges
of the EH-513 Pipe Heater will slightly overlap. Be careful not to stretch the elbow heater beyond
its original size.
- Press down firmly on all parts of the elbow heater once in place. This will activate
the pressure sensitive adhesive on the UltraHeat® Elbow Heater.
Caution: When properly installed the UltraHeat® Elbow Heater will be very
difficult to remove without destroying it.
3. Electrical Installation.
3a. Select the Appropriate 13.5 VDC Power Source.
- It is recommended that UltraHeat®'s 13.5 VDC Elbow Heaters be powered from
the output fuse panel of an RV's 13.5 VDC power converter. UltraHeat® 13.5 VDC Elbow Heaters should
not be powered directly from a motorized RV's engine battery circuit.
- All 13.5 VDC power circuits for UltraHeat® Heaters should be dedicated
to powering UltraHeat® tank, pipe and elbow heaters only.
- UltraHeat®'s 13.5 VDC Elbow Heaters can be combined on the same power circuit with
UltraHeat® Tank and Pipe Heaters as long as the following conditions are met:
|
- All UltraHeat® heaters must be connected in parallel only. All heater "hot-wire" leads
(colored red) must be connected together with the positive circuit wire. All the heater negative
wire leads (colored white) must be connected together with the circuit ground wire.
- The total current draw of all tank, pipe and elbow heaters to be combined on one
13.5 Volt DC circuit must be less than 15 Amperes.
3b. Install the 13.5 VDC, 15 Ampere fuse or circuit breaker.
- Each 13.5 VDC power circuit for UltraHeat® heaters must use only a 15
Ampere rated fuse or circuit breaker.
- Install a 15 Ampere fuse in an open fuse slot of the 13.5 VDC fuse panel connected
to the output of the 13.5 VDC power converter. If you do not have enough open circuits
in your 13.5 VDC fuse panel for the number of UltraHeat® Heaters you want to install,
please refer to the "Frequently Asked Questions About
Typical UltraHeat® Heater installations" concerning this subject. If appropriate,
install a 15 Ampere in-line fuse or circuit breaker off the direct output of the 13.5 VDC
power converter if a 13.5 VDC fuse panel is not used.
3c. Run Circuit Wire from the Fuse or Circuit Breaker to the 13.5 VDC Power Switch.
- Each 13.5 VDC power circuit must use a minimum of 14 AWG (American Wire Gage) sized
circuit wires in order to comply with National Electrical Code for 15 Ampere rated circuits.
It is acceptable to use a larger gage circuit wire (12 AWG, 10 AWG, etc.) for a 15 Ampere
rated circuit but not a smaller gage wire (16 AWG, etc.).
- Use a female slide connector (packaged with the UltraHeat® Elbow Heater) to
connect the circuit wire from the fuse/circuit breaker to the input side of the 13.5 VDC
power switch (also packaged with the UltraHeat® Elbow Heater).
3d. Run Circuit Wire from 13.5 VDC Power Switch to the UltraHeat®
Elbow Heater Positive Lead.
- Use a female slide connector (packaged with the UltraHeat® Elbow Heater) to
connect the circuit wire to the output side of the 13.5 VDC power switch.
- Use the crimp cap connectors that were packaged with your UltraHeat® 13.5 VDC Elbow
Heater to connect the heater's lead wires to the 13.5 VDC circuit wires. Connect the
positive circuit wire coming from the 13.5 VDC power switch to the red positive lead
wire on the UltraHeat® Elbow Heater.
- If larger connectors are necessary to properly connect multiple heater lead wires to the circuit wires, large crimp cap connectors are recommended (not included with the UltraHeat® Elbow Heater).
3e. Run Circuit Wire from the UltraHeat® Elbow Heater Negative Lead to Ground.
- Connect the circuit wire to be used for the ground side of the circuit using a
crimp cap connector to the UltraHeat® Elbow Heater's white negative lead wire. Run the
circuit wire back to the RV's 13.5 VDC grounding bar which is normally located near the
RV's 13.5 VDC power converter.
- It is also acceptable practice to connect the negative circuit wire directly to the RV's frame
to use as a ground for the UltraHeat® Elbow Heater. It is recommended that a crimp-on eyelet,
a star washer, a bolt and nut or other appropriate hardware be used to attach the negative circuit
wire to the RV's frame. Removing a small amount of the paint on the RV's frame where the ground
connection will be located will help insure a good ground connection.
Caution: Do not allow high voltage on the 13.5 VDC UltraHeat® Elbow Heater power
circuits, this will cause great damage to the elbow heater.
