The Profile series fan convectors are designed for installation in a forced hot water (hydronic) heating system.
They may also be used with conventional gas, oil, electric or solar powered water heaters.

IMPORTANT: BEFORE INSTALLING ANY HEATING TERMINAL UNIT TO A DOMESTIC WATER
HEATER, CONSULT YOUR LOCAL PLUMBING CODES.

When installing fan convectors, an accurate heat loss calculation of the space is required. Match unit selection with
BTUH output at system water temperature and flow rate. See the capacity chart below for output at various water
temperatures and flow rates.

1. Capacities for the PSU10, 15, 23 are based on 2 gpm. Correction factors for: .5 gpm = .80; 1.5 gpm = .96; 2.5
gpm = 1.07; 3.0 gpm = 1.12 and 5 gpm = 1.23.

2. Capacities for the PSU30 and PSU40 are based on 3 gpm. Correction factors for: 1.0 gpm = .85; 5 gpm = 1.18.

Note: AllSmith’s fan convectors include a low limit aquastat which shuts off power to the fan when water tem-
perature falls to 90ºF. Power is restored when water temperature rises to 110ºF.

U n i t I n s p ec t io n
Before starting the installation, carefully remove the fan convector from its box. Inspect for any damage that may
have been caused in handling.

Locating t h ef a n co n vec t o r
Profile series fan convectors are designed to give high BTUH capacities from a small cabinet. They should be
installed as near to the area of greatest heat loss as possible. The removable skirt enables mounting flush to the
floor or above the baseboard. Ensure adequate space to remove the cover for service and installation. Access to
piping and electrical connections are through the back OR bottom of the unit.

P r e p a r i n g t h e site
Take off the outer cover by first removing the screws located on each side, then gently lifting the casing upward
and away from the chassis. Determine the exact location of the unit and place the chassis against the wall. Mark
the locations of the piping and electrical cutouts.

Note: The piping and electrical connections may be made through the back OR bottom of the un it.

Set the chassis aside and prepare piping and electrical accordingly. To remove the bottom skirt, turn the chassis
over and take out screws located in the underside.

Installing t h ef a n co n vec t o r
Profile fan convectors are equipped with the E-Z hanger mounting strip to make installation simpler. Make a
straight level line on the wall per the diagram below. Center the E-Z hanger strip on the line and secure with the
screws provided.

Note: Make sure that the E-Z hanger strip is level. Mount the chassis by engaging the slots in the rear onto the E-
Z hanger strip. Screw the bottom of the unit into the wall through the holes provided.

Make sure the fan convector is level and secure to the wall.

Water supply and return connections are 1/2” copper tube for the PSU10, 15, 23 and 3/4” for the PSU30 and 40.
The water supply is fed at the bottom connection and the return is the top connection (with the built-in bleeder air
vent). Check to see that both soldered connectionsare leak free.

Note: Isolation valvesare recommended on both supply and return piping to allow for service and balancing if
n ecess a r y .

After filling the fan convector with water, it will be necessary to remove the air from it. A built in bleeder air vent is
located on the return pipe at the top left of the unit. This vent may be operated with a screwdriver. Be careful as
some water may be bled along with air. Since air accumulates at the high points of a system, it may be necessary to
repeat this step after initial operation.

See diagrams for recommended piping diagrams.

E lec t r ic a l C o nn ec t io n s
ALL ELECTRICAL CONNECTIONS MUST COMPLY WITH LOCAL OR NATIONAL R E G U L A T I O NS.
IF IN DOUBT, CONSULT A QUALIFIED ELE C T R I C I AN.

Smith’s Profile fan convectors are UL approved.
Remove the electrical junction box cover through the screw provided. There are two knockouts in the back and side
of the junction box. Select the most convenient and bring wiring through it. Supply conductors should be 14 AWG
and protected by a 15 AMP over current protector. Connect line input to black lead, neutral to white lead and
ground to pillar marked G inside the junction box. Refer to diagram below for complete wiring instructions.

O p e r a t io n
Before replacing the outer cover, ensure that the fan convector is operating properly. Activate the system thermostat
and place speed switch in position I. Because of the low limit aquastat, it may be several minutes before the fan
comes on. When it does come on, make sure that the switch is operational by moving to Off then II. Best results are
obtained by leaving the switch in position I and reserving II for quick heat up or extreme conditions. If the unit is
not operating, see the troubleshooting tips at the end of the manual.

U n i t m a i n t e n a n ce
The Profile series fan convectors are designed for years of trouble free operation with very little maintenance. It is
recommended however, that the unit be vacuumed occasionally through the front grille. This is especially important
in areas with lots of dust, pet hair and dirt.

If servicing is required beyond this, contact the installing contractor or

If the fan convector does not operate:

Verify that supply voltage is 120 VAC, all wires are connected and fan switch is in Min or Max position.
Verify that hot water is going to and through the unit at 130ºF or above. Both supply and return pipes should be
hot. An air bound coil will prevent the fan from operating. Bleed air from the coil if necessary.
By pass the low limit aquastat using a jumper wire. If the fan now runs, replace the aquastat.
If the fan does not run while the aquastat is jumped, replace the motor assembly.
