Installation/Startup Information

These instructions must be read and understood com-

pletely before attempting installation.

Installation or repairs made by unqualified persons can result in hazards to you and others. Installation MUST conform with local building codes or, in the absence of local codes, with the

the National Electrical Code NFPA 70/ANSI C1-1999 or current edition and Canadian Electrical Code Part 1 CSA C.22.1.

The information contained in this manual is intended for use by a qualified service technician

familiar with safety procedures and equipped with the proper tools and test instruments.

Failure to carefully read and follow all instruc- tions in this manual can result in equipment malfunction, property damage, personal injury

and/or death.

After uncrating unit, inspect thoroughly for hidden damage.

If damage is found, notify the transportation company im- mediately and file a concealed damage claim.

Improper installation, adjustment, alteration, service or maintenance can void the warranty. The weight of the condensing unit requires caution and proper handling procedures when lifting or moving to avoid personal injury. Use care to avoid contact with sharp or pointed edges.

Safety Precautions

1. Always wear safety eye wear and work gloves when installing equipment.

2. Never assume electrical power isdisconnected. Check with meter and disconnect.

3. Keep hands out of fan areas when power is connected to equipment.

4. Refrigerant causes frost-bite burns.

5. Refrigerant is toxic when burned.

R410-A systems operate at higher pressures than

standard R-22 systems. Do not use R-22 service equipment or components on Enviromax equipment.

NOTE TO INSTALLING DEALER: The Owners Instruc-

tions and Warranty are to be given to the owner or promi- nently displayed near the indoor Furnace/Air Handler Unit.

I Split System Condensers R410-A Installation Instructions I

Locating The Outdoor Unit:

Check local codes covering zoning, noise, platforms. If practical, avoid locating next to fresh air intakes, vent or

bedroom windows. Noise may carry into the openings and

disturb people inside.

Placement of the unit should be in a well drained area or unit must be supported high enough so runoffwill not enter

the unit.

Do not locate where heat, lint or exhaust fumes will be dis- charged on unit (as from dryer vents).

Clearances:

Nominal operating clearances, where practical, are 48 inches (120 cm) above unit for discharge air and 18 inches (40cm) around coil for intake air onthree sides. Clearance

on one side (normally between unit and structure) may be

reduced to 6inches (15cm). Nominal clearances are based

from a solid parallel object, wall, roof overhang, etc.

Do Not install under roof overhangs without guttering. A minimum vertical clearance of 48" is required to overhang.

The clearance may be reduced from a single object with a small surface area, such as the end of a wall, outside cor-

ner of a wall, fence section or a post, etc. As a general rule

the width ofthe object should equal the minimum clearance from the unit. For example, a 4 inch (10cm) fence post could be 4 inches (10cm) from the unit.

Rooftop installations are acceptable providing the roof will

support the unit and provisions are made for water drain- age and the noise or vibration through the structure.

NOTE: Roof mounted units exposed to winds above 5 mph may require wind baffles. Consult the factory for

additional information.

Do not install the unit ina recessed or confined area where

recirculation of discharge air may occur.

Inside corner locations on single story structures require evaluation. Large overhanging soffits may cause air recir- culation in a corner area even though recommended clear- ances are maintained. As a guide locate the unit far enough out so that half of the discharge grille is out from under the

soffit.

Two or more units may be spaced with 18 inches (45cm) between units.

A service clearance of 24 inches (60cm) is desirable from control box end or side. Control box and corner panel be-

low it can be loosened and moved out to the side to facili- tate servicing. Internal components can be accessed

through control box corner or top only.

Unit Support:

The unit must be level, and supported above grade by

beams, platform ora pad. Platform or pad can be of open or solid construction but should be of permanent materials such as concrete, bricks, blocks, steel or pressure treated timbers approved for ground contact. Refer to Unit Clear- ances to help determine size of supports etc. Soil condi- tions should be considered so the platform or pad does not shift or settle excessively and leave the unit only partially supported.

NOTE: Unit must be level to within 2 deg. (+or- 3/8 in./

ft) per compressor manufacturer specifications.

CAUTION

Inadequate support could cause excessive vibration

and noise or binding and stress on refrigerant lines re- suiting in equipment failure.

To minimize vibration or noise transmission, it is recom- mended that supports not be in contact with the building structure. However, slabs on grade constructions with an extended pad are normally acceptable.

A. Ground Level Installation:

If beams or an open platform are used for support it is rec- ommended that the soil be treated or area be graveled to

retard the growth of grasses and weeds.

B. Roof Top Installation:

This type of installation is not recommended on wood frame structures where low noise levels are required.

Supporting structure or platform for the unit must be level. If installation is on a flat roof the unit should be 4 inches

(10cm.) above roof level. Four by four posts placed over a load bearing wall make a suitable mounting platform.

If possible, place the unit over one or more load bearing walls. If there are several units, mount them on platforms that are self-supporting and span load bearing walls. These suggestions are to minimize noise and vibration transmission through the structure. If the structure is a home or apartment, avoid (if practical) locating the unit

over bedrooms or study.

NOTE: When condensing unit is to be installed on a bonded guaranteed roof, a release must be obtained from the building owner to free the installer from all liabilities.
