HIDEAVECTOR3
315 OSER AVENUE, HAUPPAUGE, NEW YORK 11788
GENERAL DESCRIPTION
HIDEAVECTOR3 heaters are for use with forced hot water residential heating systems and consist of a serpentine
copper tube, aluminum finned heating element, with an electric motor and blower of unique cross flow design. Their
purpose is to deliver a comfortable stream of warmed air, at or near floor level, and their construction is extremely
compact so minimum space is required for installation. This unit is primarily used in horizonal floor installation, for
example: under a kitchen counter cabinet, or bathroom sink enclosure. Although it is also available for verticle mounting,
fully recessed in the wall studs, with the air discharged upward through a flush mounted, louvered front panel. All
types have heating elements with 1/2" nominal (5/8 O.D.) copper tube connections, and 115V. electric blower motor,
interwired with a 120° F (49° C) reverse acting aquastat that prevents operation until hot water is circulating. These units
are NOT intended to be used on one or two pipe steam systems. See bottom of page 7. For gravity fed systems, it is
recommended that a separate circulator pump be installed for the kick space heater.
INSTALLING HIDEAVECTOR (FLOOR MOUNT)
1. Select a location under the bottom shelf of a cabinet that meets the minimum dimensions shown in Fig. 1.
2. CUT AN ACCESS PANEL THROUGH THE BOTTOM OF THE CABINET AT THIS LOCATION, LARGE ENOUGH
FOR INSTALLATION AND SERVICE. IT IS RECOMMENDED THAT THIS ACCESS PANEL BE CONSTRUCTED SO
ANNUAL CLEANING OF THE BLOWER FAN AND COIL FINS CAN BE EASILY ACCESSIBLE.
3. At this location, center and cut an opening in the toe-space riser 4'' high x 11'' long (HAV-48-3) (See figure 1)
or 4'' high x 18'' long (HAV-88-3) (See figure 2).
4. Set the HIDEAVECTOR3 in the space at finished floor level and check piping and wiring locations. The air outlet
should be facing but not extending beyond the toe-space riser at the opening. The air outlet should also be located at
the bottom portion of the 4'' toe-space riser (See figure 1) at finished floor level. Make sure the switch is accessible
through the grille opening. The front of the unit should fit flush to the inside of the toe space riser.
6. If using the "Easy Connect" Flexible Hose Connection Kit, see those installation instructions.
7. Next, prepare the heating element for pipe connections (this procedure will also pertain to floor and wall models).
Remove the screws from the electric conn. box. Unsnap (pull) the thermostat clamp from the return copper U-bend.
Holding down the top cover, remove the 4 element cover screws. Carefully remove this top cover noting the position of
the element and the neoprene side pad. Lift out the element for soldering and fittings. Both ends are sized to accept
1/2'' solder fittings. (Note required fittings for one pipe and two pipe systems on page 6).
8. Replace the heating element in the bottom cover in the proper position. Place the neoprene side pad in position and
replace the top cover using the 4 screws. Tighten enough to keep the element in place between the covers. DO NOT
OVER-TIGHTEN!
9. Place the HIDEAVECTOR3 under the cabinet and connect the piping and wiring. Make sure unit & outlet are free
of any dirt or debris prior to start up. Turn on the system, purge of air, check blower operation and check for any
possible leaks in the piping (run for 2 hrs. minimum). It should then be screwed to the floor through the four resilient
mounting feet (2-inside electrical box and 2 external). Do not over-tighten screws. Secure top of electrical box.

A shaded pole motor is used to drive the Hideavector3 blower on 115 -120 V. 60 hz. Since current drain
is very small, wiring codes for short circuit protection only will apply. The motor is connected in series with a
normally open aquastat in contact with the heating element. Therefore, the blower runs only when unit is suffi-
ciently hot and the switch is in the "min" or "max" position (not "off"). A ground screw is supplied with all units.
Electrical connections are to be made to all units following the diagrams below. Choose the diagram that
best suits your application.
Since the blower runs on all Hideavector3 models only when the system circulator pumps hot water
through the unit, simply connect it to the 115 V line. The blower then starts after a short warm-up, and stops a
few minutes after the circulator shuts off (see diagram #1).
Adding a line voltage type room thermostat will permit the setting of a maximum room temperature (see
diagram #2). This 'T' stat will only operate the fan/coil unit. If the circuit or system circulator is not running, the
fan/coil unit will not operate.
All electrical connections must conform to local and national codes.
Connection through a circulator or zone auxiliary switch may also be used to permit instant shutdown of the
blower as the circulator stops (see diagram #3).

Embassy Hideavector3 Heaters should be connected only to circulating hot water systems where at
least 1 gpm water flow is expected. They are essentially small unit heaters, and will work on one or two pipe
systems, or in a series loop where pressure and temperature drop can be tolerated (see capacity charts and
piping diagrams). These units are not designed for use with steam systems. See bottom paragraph on page 7.
These units are not recommended to be used with a gravity flow system.
6.
Piping Charts
System Considerations
Maintenance & Service
Properly installed, the Embassy Hideavector3 heater should require very little attention. Since the heating
element is carefully constructed and tested, and of non-ferrous materials, it should never require service. The
cross-flow blower has been thoroughly engineered, with ball bearings for 10,000 hrs. bearing life expectancy.
As with any electrical rotating device, a yearly inspection and cleaning is recommended. Wherever
there is air movement, there will be some accumulation of dust and lint. In this case it will collect on the rotor
blades and air passage of the unit. Regular cleaning with a vacuum cleaner tool is advised, with frequency de-
termined by prevailing conditions. Always make sure that the air grille is not blocked by foreign objects
or materials.
NOTE: In an up feed system, unit is located above hot water supply line. In a down feed
system, unit is located below hot water supply line.
For One Pipe System Down Feed, two directional flow tees should be used. They should be spaced
12 to 18 inches apart. The directional arrow on the directional flow 'T' at the return side should point
towards the supply directional flow 'T'.
If directional flow (mono-flo) tee's are not available, an adjustable screw operated flow control or cir-
cuit setter can be placed between the two standard tee's in a one pipe system.
For consistent response of the reverse acting thermostat, and effective outlet air temperature,
the average water temperature should not be below 140° F (60° C). Blower motor shuts off at
120° F (49° C) and will not operate until water temperature reaches 140° F (60° C).
If utilizing water temperature below 140° F (60° C), the blower will not operate with the self contained aqua-
stat. An optional low temperature aquastat, 120° to 105° F (49° to 41° C) is available.

On a typical forced hot water system, connect return to inlet side of circulator and supply upstream of
remotely operated valve. Unit may also be connected to mains of an existing loop system of sufficient capacity.
Operation will be influenced by the system circulator and associated controls.
Installation of a pump and line voltage thermostat will provide the unit with its own “zone” control.
With the addition of a circulator pump, hot water storage tanks may be used (where codes permit) as a supply
source if proper precautions are taken, and if realitively low water temperatures can be tolerated. Be sure tank
can supply additional load of the Hideavector3 and 140° F water. Supply is taken from top of tank, and returns
at the cold water inlet with a check valve. Do not return to bottom drain tapping.
Operation from steam boiler water is entirely possible as long as supply and return connection is installed
below level of water line on a steam boiler. This installation requires an optional circulator pump and line
voltage thermostat. Check local building codes.
