UNIT LOCATION

DANGER

Units must not be installed where they may be exposed to a potentially explosive or flammable atmosphere.

1. Units should not be installed in atmospheres where corrosive fumes or sprays are present.

2. Be sure no obstructions block air intake or air discharge of unit heater.

3. Columns, machinery, partitions, and other obstacles should not interfere with air streams from unit heaters.

4. Unit heaters installed in a building exposed to a prevailing wind should be located to direct a major volume of heated air along the windward wall of the building.

5. Vertical delivery unit heaters should generally be located in the central area of the space to be heated. Place horizontal delivery units along the walls of the same building where heat loss is usually greatest.

6. Arrange horizontal delivery units so they do not blow directly at occupants.

7. When only vertical delivery units are installed, they should be located so exposed walls are blanketed by their air streams.

8. Mounting height is critical for optimum performance. Refer to Mounting Height on page 4 before installation.

CAUTION

1. Do not reuse any electrical component which has been wet. Such component must be replaced.

2. Do not operate the units within steam pressure greater than 10 psig. Steam pressure must be 10 psig. or lower to avoid excessive discharge air temperatures that could cause burns or personal injury.

IMPORTANT

Start-up and adjustment procedures must be performed by a qualified service agency.

INSTALLATION - UNIT MOUNTING / PIPING / ELECTRICAL CONNECTIONS

INSTALLATION Unit Mounting

1. Open front panel and line up end compartment with roughedin piping and position unit at ceiling or wall location. (Hinged cabinet doors may be removed to facilitate unit installation.)

2. Fasten floor or wall mounted unit to wall studs through the four mounting holes in the back of the unit. For ceiling mounted units sizes 002-006, suspend four 1/4" threaded hanger studs from ceiling joists to match mounting holes in back of unit and fasten with lockwashers and hex nuts. (For sizes 008-014, use a 3/8" threaded rod.)

Perma-Lap® Frames

A Perma-Lap® frame (see Figure 11.3 on page 10) provides a finished appearance to a recessed wall or ceiling cabinet unit heater. The installation is easy and assures a perfect fit by neatly framing the heater and covering any irregularities between the heater and the opening in the wall or ceiling. Because the bond between wall or ceiling surfaces and the Perma-Lap® framing is permanent, there is no opportunity for air leakage which can cause wall streaking.

Since the enclosure front panel is never in contact with the wall or ceiling, servicing the heater involves simply removing the heater front panel and leaving the Perma-Lap® and cabinet enclosure permanently fixed in the recess opening.

Perma-Lap® frames allow flexibility in recessing depth. Enclosures may be flush, recessed or partially recessed. Desired unit projection on partially recessed units is accomplished by positioning the unit within the Perma-Lap® frame. The four sided Perma-Lap® frame has a 3/8” projection and a 1 ½” width.

Piping

CAUTION

Failure to wire this unit according to this wiring diagram may result in injury to the installer or user. For deviations, contact the factory.

1. Installation of wiring must conform with local building codes, or in the absence of local codes, with the National Electric Code ANSI/NFPA 70 - Latest Edition. Unit must be electrically grounded in conformance to this code. In Canada, wiring must comply with CSA C22.1, Electrical Code.

2. Electric wiring must be sized to carry the full load amp draw of the motor and any controls that are used with the unit heater. Overcurrent protectors should be sized based on motor current rating shown on the unit serial plate, and applicable national electric code procedures.

All units are provided with an electrical junction box. Make

wiring connections from 115V/60Hz/1Ø building service to control box as shown on wiring diagram furnished with the unit.

Any damage to or failure of Modine units caused by

incorrect wiring of the units is not covered by Modine’s

standard warranty.

3. Location of room thermostat, when supplied, should be in the natural circulating path of room air. Mount thermostat about five feet above floor level where it will not be affected by heat from the unit or other sources of drafts that would prevent it from properly controlling room temperature. See instructions packed with the thermostat.

4. With ceiling mounted units, a multi-speed remote fan switch is supplied as standard. The switch can be recessed into a standard 2 x 4 electrical wall box.

1. Do not reuse any electrical component which has been wet. Such component must be replaced.

1. On standard coil (single row), connections are 3/4" MPT on unit sizes 002 through 006.

On high capacity coil (2 row), connections are 5/8" ID sweat

on unit sizes 002 through 006. On high capacity coil (3 & 4 row), connections are 3/4" NPT on unit sizes 002 through 006.

On unit sizes 008 through 014, either standard or high capacity

coil, connections are 1" NPT. On high capacity coil (3 & 4 row), connections are 1" NPT on unit sizes 008 through 014.

2. Supply and return lines should be adequately sized to handle heating requirements under maximum load.

3. Attach air vent fitting at the high point of the piping in the unit on hot water systems.

4. Install piping to provide for expansion and contraction normally encountered with temperature changes.

Electrical Connections

WARNING

1. Disconnect power supply before making wiring connections to prevent electrical shock and equipment damage.

INSTALLATION - MOUNTING HEIGHT / OPERATION

Mounting Height

Height at which cabinet unit heaters are installed is critical. Maximum mounting heights for all units are listed in the tables below. The data in tables are based on operating conditions of 2 lbs. steam or 220°F entering water with 60°F entering air. When operating conditions are other than those above, refer to chart for mounting height correction factor. To obtain the maximum mounting height at actual operating conditions, multiply the appropriate factor from chart by the mounting height in Tables. The mounting heights must be followed closely to assure maximum comfort.

Strong opposing drafts, large obstructions in the air stream of the unit, and higher than normal discharge air temperatures (resulting from high steam pressures) can prevent the heated air discharged by the cabinet unit from reaching the floor.

Under unfavorable conditions such as these, allowances must be made to assure maintenance of desired comfort.

Automatic Control Operations

Install one of the following operating systems for continuous automatic control.

Intermittent Fan Operation — Hot Coil

A room thermostat starts and stops the fan motor. An aquastat is sometimes strapped to the return piping to prevent fan operation when heat is not being supplied to the unit heater.

Continuous Fan Operation — Intermittent Hot/Cold Coil

A room thermostat controls a valve which opens to allow steam or hot water to supply the unit and closes to shut off the supply when the thermostat is satisfied.

MAINTENANCE / SERVICE

All heating equipment should be serviced before each heating season to assure proper operations. The following items may be required to have more frequent service scheduled based on the environment in which the unit is installed, and the frequency of the equipment operation.

Motors

A. Cleaning

Remove grease and dirt on motor during each inspection or lubrication. Open frame motors should be blown clean every heating season, or whenever coils are cleaned, whichever is sooner.

B. Lubrication

1. Lubricate motor according to manufacturer’s instructions

located on the motor.

2. When no motor oiling instructions are on the motor, oil the motor every two thousand hours of operation with SAE20 non-detergent motor oil for units in normal applications. Adjust oiling according to usage and atmosphere.

3. Some motors do not have oil fittings. These motors are lubricated for long life and do not require further lubrication.

4. Check motor shaft for excessive end play every 3 to 5 years.

C. Overload Protection

A change in line voltage higher or lower than motor nameplate rating may cause overheating and serious motor damage. Check plant voltage conditions. A separate manual starter with thermal overload protection device is recommended for those units that do not have motors with built-in overload protection.

Coils

A. Cleaning

Clean coil at least once a year; more often under unfavorable conditions. Unless coil is kept reasonably free of dirt, lint and grease, its original heating capacity will be reduced — possibly to a serious degree, and motor damage may result.

Two commonly used cleaning methods are:

1. Loosen dirt by brushing fins with a soft brush on side where

air enters coil and then turn on fan to blow dirt from unit.

2. Use high pressure air hose to loosen dirt by blowing from

side where air leaves coil (side adjacent to louvers on blowthrough units; side adjacent to fan on draw-through units).

Coils subjected to corrosive fumes should be checked and cleaned frequently.

Do not use any commercial solvent that could deteriate the coil and do not use any liquid or steam sprays that could damage electrical components.

Good filter maintenance will minimize the frequency of coil cleaning.

B. Internal Corrosion Safeguards

1. Provide controlled water treatment — don’t use excess of

boiler compounds. Contact your boiler compound supplier for proper usage or the services of a water treatment laboratory.

2. Periodic internal flushing of the coils is recommended in areas where water supply is suspected of causing scale. Use an alkaline-chelant solution and introduce it at the main pump of the hydronic system. Flush thoroughly.

WARNING

Using inorganic or mineral acids, such as muriatic (hydrochloric) acid, even though inhibited, may lead to severe damage including corrosion and leakage.

3. De-aerate boiler feed-water (particularly if large amount of new water is used).

4. Insure rapid continuous and adequate condensate drainage by properly sized and installed traps and piping. Check traps for sticking. Clean strainers ahead of traps. (When traps

don’t work, condensate accumulates in unit heater coil;

water hammer results.)

5. Adequately vent each unit.

6. Use low pressure steam when possible.

Casings

A. Cleaning

1. Periodic cleaning of casings is recommended to remove dirt,

grease and corrosive substances that may injure finish. Rusted or corroded spots should be cleaned and repainted.

2. Clean air filters every three months or sooner depending on

dust conditions.

B. General Inspection

Tighten fan guard and motor bracket. Check fan for proper clearance, free rotation and firm connection to shaft.

When servicing is complete, tag unit to indicate date of inspection, lubrication and cleaning.

SERVICE

If a qualified service person cannot solve the problem, consult your local plumbing/electrical contractor or local Modine representative.

When servicing, repairing or replacing parts on these units always give the complete Model Number and Serial Number from the unit identification plate.

Replacement Parts

When requesting parts please contact your local representative. Please have full model and serial number available.
