NOTICE

NTRODUCTION

This booklet contains the installation and operating instruc-

tions for your modular blower cabinet. All warnings and pre-

cautions within this booklet must be observed. Improper in-

stallation can result in unsatisfactory operation or dangerous

conditions and void 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 config-

ured in accordance with the Electric Heating Airflow Table

on page 7 of 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 instal-

lation and servicing to protect the integrated control module

from damage. By putting the modular blower, the control,

and the person at the same electrostatic potential, these steps

will help avoid exposing the integrated control module to elec-

trostatic discharge. This procedure is applicable to both in-

stalled and uninstalled (ungrounded) 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.

BLOWER CABINET INSTALLATION INSTRUCTIONS

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.

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.

MBVC BLOWER CABINET INSTALLATION INSTRUCTIONS THIS PRODUCT CONTAINS ELECTRONIC COMPONENTS WHICH REQUIRE A DEFINITE GROUND. PROVISIONS ARE MADE FOR CONNECTION OF THE GROUND. A DEDICATED GROUND FROM THE MAIN POWER SUPPLY OR AN EARTH GROUND MUST BE PROVIDED. NOTICE IF AN “EC” ERROR IS ENCOUNTERED ON STARTUP, VERIFY THAT THE ELECTRIC HEATER DIP SWITCHES HAVE BEEN SET TO THE APPROPRIATE HEATER SIZE. DELIVERY AND SEE PAGES 7 AND 8 FOR THE HEATER KIT AIRFLOW DIP SWITCH SETTINGS.
PAGE 2
Systems should be properly sized by heat gain and loss calculations made according to methods of the Air Conditioning Contractors Association (ACCA) or equivalent. It is the contractor’s responsibility to ensure the system has adequate capacity to heat or cool the conditioned space. WARNING HIGH VOLTAGE! DISCONNECT ALL POWER BEFORE SERVICING . MULTIPLE POWER SOURCES MAY BE PRESENT . FAILURE TO DO SO MAY CAUSE PROPERTY DAMAGE , PERSONAL INJURY OR DEATH .
PAGE 3
Secure the coil and blower together with the two connector plates and screws supplied in the blower bag assembly. Use one connector plate and six screws on each side of the unit. If accessory electric heat is to be added, install now per the instructions shipped with the heater kit. UPFLOW INSTALLATION Air Flow For upflow installations, the blower cabinet must sit on top of the coil cabinet (Figure 2). NOTE: All panels should be in place before installing the cabinet. 1.

determine proper wire size. The unit MUST be properly grounded. A ground lug is provided in the unit. Rods Check all factory connections before connecting electrical power to unit to ensure none were loosened or disconnected during shipping and handling. WARNING HIGH VOLTAGE! Support TO PREVENT PERSONAL INJURY OR DEATH DUE TO ELECTRICAL SHOCK, DISCONNECT THE ELECTRICAL Access Panel POWER BEFORE ELECTRICALLY CONNECTING THE UNIT. Figure 5 - Hanging Installation 2.

24 VOLT THERMOSTAT WIRING NOTE: Wire routing must not interfere with the circulator blower operation or routine maintenance. 1 The modular blower’s integrated control module provides terminals for “Y1” and “Y2” and “W1” and “W2” thermostat connections. This allows the modular blower to support the systems shown in the table below. Refer to the following figures for typical connections to the integrated control module. Thermostat wiring entrance holes are located in the top of the blower.
PAGE 6
The cooling system manufacturer’s instructions must be checked for required air flow. Any electronic air cleaners or other devices may require a specific airflow; consult installation instructions of those devices for requirements. 3. Knowing the modular blower model, locate the high stage cooling air flow charts in the Specification Sheet applicable to your model. Look up the cooling air flow determined in step 2 and find the required cooling speed and adjustment setting.

FAULT RECALL TROUBLESHOOTING The integrated control module is equipped with a momentary push-button switch that can be used to display the last six faults on the 7 segment LED display. The control must be in Standby Mode (no thermostat inputs) to use the feature. Depress the push-button for approximately two seconds and less than five seconds. The LED display will then display the six most recent faults beginning with the most recent fault and decrementing to the least recent fault.
PAGE 10
System Air Conditioner + Air Handler Heat Pump + Air Handler Typical 18 AWG thermostat wire may be used to wire the system components. However, communications reliability may be improved by using a high quality, shielded, twisted pair cable for the data transmission lines. In either case, 100 feet is the maximum length of wire between indoor unit and outdoor unit, or between indoor unit and thermostat.

MODULAR BLOWER ADVANCED FEATURES MENU CONFIGURATION Submenu Item Electric Heat Size (HTR KW) Indication (for Display Only; not User Modifiable) Displays the size in kW of the selected electric heaters. Motor HP (1/2, 3/4, or 1 MTR HP) Displays the modular blower indoor blower motor horsepower. Heat ON Delay (HT ON) Displays the electric heat indoor blower ON delay. Heat OFF Delay (HT OFF) Displays the electric heat indoor blower OFF delay.

• DIAGNOSTICS Accessing the modular blower’s diagnostics menu provides ready access to the last six faults detected by the modular blower. Faults are stored most recent to least recent. Any consecutively repeated fault is stored a maximum of three times. Example: A clogged return air filter causes the modular blower’s motor to repeatedly enter a limiting condition. The control will only store this fault the first three consecutive times the fault occurs.
