INSTALLATION INSTRUCTIONS:: Pipe Heater |
Detailed Installation Instructions for UltraHeat® Pipe 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® Pipe Heaters.
Caution: UltraHeat® Pipe Heaters can only be installed on rigid/hard plastic pipes.
1. Prepare the Pipe Surface.
- Select the location on the bottom of the drain pipe or fresh water
supply pipe where the pipe heater is to be put.
- For Drain Pipes: Locate the UltraHeat® Pipe Heater or combination of
UltraHeat® Pipe Heaters that will cover the majority of the exposed drain pipe
and leave no more than 2" to 3" (5.08-7.62 cm) spaces between pipe heaters or on the ends of the
drain pipe section to be protected.
- For Fresh Water Supply Pipes: To protect a section of ½" (1.27 cm) fresh water
supply pipe, use one (1) PH-513 Pipe Heater per 12" (30.48 cm) of pipe below the floor of your RV.
Locate the first PH-513 Pipe Heater near the fresh water tank and leave at most a ½" (1.27 cm) space,
then place the second PH-513 Pipe Heater, then repeat as necessary. To enhance the level of freeze
protection, it is recommended that foam insulation be placed over the UltraHeat®
pipe heaters.
- Pre-clean the dust, dirt and other foreign matter from the drain pipe or
fresh water supply pipe surface using soap and water. Rinse with clean water and
let the pipe surfaces dry completely.
- Next clean the drain pipe or fresh water supply pipe surface using isopropyl alcohol
(70% alcohol minimum) and a clean cloth or rag. Allow the pipe surfaces to
dry completely. The pipe surfaces must be clean and dry before proceeding to the next step.
Caution: Do not use any type of solvent to clean the pipe surfaces.
2. Put the Pipe Heater onto the Pipe Surface.
- Peel the release paper off the back side of the pipe heater exposing the
adhesive side of the pipe heater.
- For Drain Pipes: Place the pipe heater onto the bottom pipe surface with
the adhesive side against the pipe. Start by placing the center of pipe heater
on the bottom of the pipe so that the long edges of the pipe heater will align
with the length of the drain pipe. Wrap the long edges of the pipe heater up
towards the top of the drain pipe. Firmly press the pipe heater down so that
the entire pipe heater makes contact with the pipe surface. Be careful not to
stretch the pipe heater beyond its original size. Do not spiral wrap UltraHeat®
Pipe Heaters on drain pipes, the heating element should be on the bottom of the
drain pipe so that heat rises into the drain pipe from the bottom.
- For Single Fresh Water Supply Pipes: Start by placing the center of
PH-513 Pipe Heater on the fresh water supply pipe so that the long edges of the
pipe heater will align with the length of the pipe. Wrap the long edges of the
PH-513 Pipe Heater around the fresh water supply pipe, one side at a time. The
long edges of the PH-513 Pipe Heater will slightly overlap. Firmly press the pipe
heater down so that the entire pipe heater makes contact with the pipe surface.
Be careful not to stretch the pipe heater beyond its original size.
Caution: Do not spiral wrap the PH-513 Pipe Heater on a single fresh water supply pipe.
- For Double Fresh Water Supply Pipes: Double fresh water supply
pipes are any two fresh water supply pipes that run parallel to each other so they
are touching. Spiral wrap the PH-513 Pipe Heater around the outside of both fresh
water supply pipes so they are bound together. Be careful not to stretch the pipe
heater beyond its original size.
- Press down firmly on all parts of the pipe heater once in place. This will
activate the pressure sensitive adhesive on the UltraHeat® Pipe Heater.
Caution: When properly installed the UltraHeat® Pipe 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 Pipe Heaters be powered from
the output fuse panel of an RV's 13.5 VDC power converter. UltraHeat® 13.5 VDC Pipe
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 Pipe Heaters can be combined on the same power circuit
with UltraHeat® Tank and Elbow 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® Pipe 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® Pipe Heater.)
3d. Run Circuit Wire from 13.5 VDC Power Switch to the UltraHeat® Pipe Heater Positive Lead.
- Use a female slide connector (packaged separate from the UltraHeat® Pipe 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
Pipe 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® Pipe 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® Pipe Heater).
3e. Run Circuit Wire from the UltraHeat® Pipe 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® Pipe 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® Pipe 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® Pipe
Heater power circuits, this will cause great damage to the pipe heater.
