HEAT PUMP INSTALLATION

HEAT PUMP INSTALLATION

Locating the Heat pump

Select a solid, level position, preferably on a concrete slab, slightly above the grade level, and parallel to the home. DO NOT PLACE

UNIT UNDER THE HOME.

The hot condenser air must be discharged up and away from the home, and if possible, in a direction with the prevailing wind.

Do not place the unit in a confi ned space.

If practical, place the heat pump and its ducts in an area where they will be shaded from the afternoon sun, when the heat load is greatest.

If possible, select a site for the unit that is as close as possible to the proposed return grille location.

The length of the supply and return ducts should be kept to a minimum with no sharp radius bends.

Unpacking the Unit

It is recommended that the unit be unpacked at the installation site to minimize damage due to handling.

UNIT UNDER THE HOME. CAUTION:

Do not tip the unit on its side. Oil may enter the compressor cylinders and cause starting trouble. If unit has been set on its side, restore to upright position and do not run for several hours.Then run unit for a few seconds. Do this three or four times with five minutes between runs.

1.Remove the bands from around the unit.

2.Unfold the top and bottom cap fl anges.

3.Carefully remove the top cap and tube.

Minimum Clearances

Minimum clearances MUST be maintained from adjacent structures to provide room for proper servicing and air circulation. See Figure 2. DO NOT install unit in a confined or recessed area that will allow discharge air from the unit to re-circulate into the condenser air inlet, through the coil.

Duct Requirements

The supply duct system, including the number and type of registers, will have much more effect on the performance of an air conditioning system then any other factor. The duct must be sufficiently large to conduct an adequate amount of air to each register.

CONDENSATE DRAINAGE

A 3/4” condensate fi tting extends out of the side of the unit (Figure 3). The drain trap, shipped in the electrical compartment, must be installed to prevent water from collecting inside the unit.

1.Thread the elbow provided with the unit into the drain connection until hand tight.

2.Connect the condensate tubing onto the fitting, forming a trap near the drain connection.

3.Route the condensate tube from the trap to a suitable drain. NOTE: For proper drainage, make sure the trap is level to the ground and tubing outlet is below trap level.
