N.B. Cut off power supply at circuit breaker/fuse before proceeding with installation.

Please note that each air handler is factory inspected before shipping in order to ensure that every component is operating efciently.

The SCV series air handler is available in several models of various capacities (from 400 to 2200 CFM). Since they are multi-positions units, all

models adapt easily to many applications and are suitable for horizontal, upow and downow operations as shown in Fig. 5. In all cases, the

air inlet can be connected on the left, right, bottom or back side of the unit. The discharge is always connected on the top side of the air handler.

When installed in vertical downow position (top side facing down), use only a ‘‘L’’ or ‘‘T’’ shaped plenum, without openings or registers directly

below the unit.

AIR HANDLER INSTALLATION

LOCATION

You must install the air handler on a dry and solid base or in a suspended ceiling. The area must be free of ammable liquids or vapors and

combustible materials. If you choose to suspend the unit, you must assemble the four (4) ‘’L’’ brackets (M-SCV39Z0) into the matching corner

slots as shown in the gure below. You must indicate to the air handler’s user the location of the switches and disconnects. He must be able to

quickly identify them in case of an emergency. Moreover, the air handler should be located, as centrally as possible, in the area to ventilate, in

order to optimize air distribution in all rooms.

CLEARANCE

The air handler is approved for ‘‘zero inch’’ clearance. It means that you can install it directly against a wall. Ducts for models of 1400 CFM and

less can also be installed with a zero inch clearance (0 inch). However, ducts for model of 2200 CFM and more must have a 1-inch clearance for

the rst 36 inches of duct. Beyond 37 inches, this clearance can be reduced to 0 inch. If you have any questions concerning clearances, please

refer to the codes effective in your region

Since it is necessary to open the door in the front to perform the air handler maintenance inspection, you must leave at least a 24-inch clearance

in front of this door.

DUCTS

Ducts must be designed to deliver airows to the specied external static pressure. You should insulate the ducts crossing non-heated areas.

Moreover, use exible return and supply connectors in order to avoid vibrations as much as possible. To make your air handler even quieter, follow

these instructions:

1. Cover the vertical return and supply ducts with soundproong material

2. Install at most one or two elbows between registers and the return and supply connectors

3. Install exible hangers to suspend the ducts

4. Install bafes in elbows with a small radius of curvature

OPTIONAL ACCESSORIES

The air handler is equipped with all devices required for the addition of an air-conditioner or heat pump (except the heat-cool thermostat). The

refrigerant and drainage pipes must be installed either in the air handler’s supply or return duct and should not prevent you from removing the

front door of the air handler. You can also install a thermostat with an outdoor sensor or a two stage thermostat to control your air handler. For this

type of installation, refer to the instructions supplied with the thermostat as well as the air handler’s wiring diagram.

N.B. Please note that if one of these accessories is installed, you must refer to the appropriate guide.

Note that this product must be connected by a qualied electrician according to the electrical and building codes effective

in your region.

This air handler must be connected to a 120 or 240/208 volt power source, depending on the model. For 240V power supply, either copper or

aluminum wires can be used, except for 2200 CFM models where only copper wires can be used. If you want to energize the air handler at 208

VAC, you must modify a connection on the transformer’s terminal block: replace the wire connected to L2/N by the wire not connected (isolated).

Refer to the local and national electrical codes to know which wire size, fuses and circuit breakers are required.

You can also connect a 24 VAC humidier directly to the 24 VAC power supply of the air handler, e.g. on R and C terminals of the terminal block.

NO CONTROL

When the air handler is used with no controller (model # SCV-P-xx0x), the power cable must be wired through one of the two Ø7/8’’ KOE (electrical

knock outs), located on either side (right and left) of the air handler, and connected to the appropriate wires in the junction box, as shown in Fig.

7. We suggest the operator add an external switch or relay to control the air handler unit:

LOW VOLTAGE CONTROL

When the air handler is used with low voltage control (model # SCV-P-xx4x), the power cable must be wired through one of the two Ø 7/8’’ KOE

(electrical knock outs), located on either side (right and left) of the air handler, and connected to the appropriate terminal blocks in the junction

box, as shown in Fig. 8. The low voltage control gives the installer the possibility to control the air handler unit with a low voltage contact, e.g. a

24V thermostat. In this case, the installer must use a different knock-out than the one used with the power cable (high voltage) and must connect

the external low voltage wires to the appropriate terminal blocks in the junction box, as shown in Fig. 8.

WITH LOCAL CONTROL BOX

When the air handler is used with a local controller (model # SCV-x-xx1x), the installer can connect the unit by passing through a knock-out

Ø7/8’’, located on either side (left and right) of the air handler cabinet, and connect to the terminal block as shown in Fig. 9. When the air handler

is properly connected, the installer can connect the controller to the thermostat by passing through a different electrical knock-out Ø7/8’’ than the
