NOTICE

THIS PRODUCT CONTAINS ELECTRONIC COMPONENTS WHICH REQUIRE A DEFINITE

GROUND. PROVISIONS ARE MADE FOR CONNECTION OF THE GROUND. A DEDI-

CATED GROUND FROM THE MAIN POWER SUPPLY OR AN EARTH GROUND MUST

BE PROVIDED.

NTRODUCTION

This booklet contains the installation and operating instructions

for your modular blower cabinet. All warnings and precautions

within this booklet must be observed. Improper installation can

result in problems ranging from noisy operation to property or

equipment damages, dangerous conditions that could result in

injury or personal property damage and that are not covered by

the warranty. Read this booklet and any instructions packaged

with accessories prior to installation. Give this booklet to the user

and explain its provisions. The user should retain this booklet for

future reference.

NOTE: Upon start up in communicating mode the circuit board

may display an “Ec” error. This is an indication that the dip switches

on the control board need to be configured in accordance with

the Electric Heating Airflow Table in this manual. Configuring the

dip switches and resetting power to the unit will clear the error

code.

ELECTROSTATIC DISCHARGE (ESD) PRECAUTIONS

NOTE: Discharge body’s static electricity before touching unit. An

electrostatic discharge can adversely affect electrical components.

Use the following precautions during modular blower installation

and servicing to protect the integrated control module from dam-

age. By putting the modular blower, the control, and the person

at the same electrostatic potential, these steps will help avoid ex-

posing the integrated control module to electrostatic discharge.

This procedure is applicable to both installed and uninstalled (un-

grounded) blowers.

1. Disconnect all power to the blower. Do not touch the

integrated control module or any wire connected to the

control prior to discharging your body’s electrostatic charge

to ground.

2. Firmly touch a clean, unpainted, metal surface of the

modular blower near the control. Any tools held in a

person’s hand during grounding will be discharged.

3. Service integrated control module or connecting wiring

following the discharge process in step 2. Use caution not

to recharge your body with static electricity; (i.e., do not

move or shuffle your feet, do not touch ungrounded

objects, etc.). If you come in contact with an ungrounded

object, repeat step 2 before touching control or wires.

4. Discharge your body to ground before removing a new

control from its container. Follow steps 1 through 3 if

installing the control on a blower. Return any old or new

controls to their containers before touching any

ungrounded object.

CHECKING PRODUCT RECEIVED Upon receiving the unit, inspect it for damage from shipment. Claims for damage, either shipping or concealed, should be filed immediately with the shipping company. Check the unit model number, specifications, electrical characteristics and accessories to determine if they are correct. In the event an incorrect unit is shipped, it must be returned to the supplier and must NOT be installed. The manufacturer assumes no responsibility for installation of incorrectly shipped units.
PAGE 3
GENERAL INFORMATION The MBVC Blower Cabinets are used in combination with a cased evaporator coil. This combination of blower and coil functions as the indoor part of a split air-conditioning system, and may be matched with a remote condensing or heat pump unit. The blower cabinet can also function as an electric furnace when used with an electric heater. NOTE: The electric heating elements for electric furnace installation are not shipped with the cabinet and are field-installed.
PAGE 4
COUNTERFLOW INSTALLATION For counterflow installations, the evaporator coil cabinet must sit on top of the blower cabinet (Figure 3). NOTE: All panels should be in place when installing the unit. NOTE: Supply ductwork for counterflow applications, must be Class I. However, if combustible ductwork is used, sheet metal protection is required. Support Figure 4 - Attic Installation 4. Attach return and supply ductwork. Seal connections. 5.
PAGE 5
ELECTRICAL CONNECTIONS WARNING Consult the local power company and local codes before installing this unit. All wiring must be in accordance with the National Electrical Code as well as all local codes. Knockouts have been provided on side and top of the cabinet for the installation of the electrical conduit. If the knockouts on the cabinet sides are used for electrical conduit, an adapter ring must be used in order to meet UL1995 safety requirements.
PAGE 6
AUXILIARY ALARM SWITCH The control is equipped with two Auxiliary Alarm terminals labeled CAS which can be utilized with communicating mode setups (typically used for condensate switch wiring but could be used with compatible C02 sensors or fire alarms). 1 2 Legacy mode use In a legacy system (Non-communicating), this feature is not operational. Any auxiliary alarm switch must be used to interrupt the Y1 signal either to the indoor or outdoor unit.

• Profile C ramps up to 82% of the full cooling demand airflow and operates there for approximately 7 1/2 minutes. The motor then steps up to the full demand airflow. Profile C also has a one (1) minute 100% OFF delay.

AIR HANDLER AIR HANDLER HOMEOWNER’S ROUTINE MAINTENANCE RECOMMENDATIONS We strongly recommend a bi-annual maintenance checkup be performed before the heating and cooling seasons begin by a qualified servicer. An alternate cleaning method is to use one of the products listed in TP-109* to clean the coils. The cleaners listed are the only agents deemed safe and approved for use to clean round tube aluminum coils. TP-109 is also available on the web site in Partner Link > Service Toolkit.
