Location The SPV series units are designed to be installed in an interior closet that is against an outside wall, with rear or side access. The vertical discharge is ducted to one, or several rooms, depending on the application. The exterior of the unit (outdoor grille side) must have no obstructions (ie. trees, bushes, walls, etc.) within 18 inches. Do not install two units adjacent to each other, on an inside corner, as the units will not properly function if they exhaust into each other.

Interior closets must be designed to allow access to the indoor side of the unit, for installation, inspection and service. The closet opening must be at least 24” wide and 84” tall, for size 9 – 24 units, and at least 32” wide and 84” tall for size 25 – 36 units. Three inches (3”) of unobstructed space is required on all sides of the SPV, to allow for adequate air flow. A minimum of 27” (sizes 9 – 24) and a minimum of 35” (sizes 25 – 36) must be provided in front of the interior portion of the unit, to permit removal of the unit, for inspection and service.

Typical Closet Installation

This unit is not meant to provide unattended cooling or life support for persons or animals who are unable to react to the failure of this product. The failure of an unattended air conditioner may result in extreme heat in the conditioned space, causing overheating or death of persons or animals.

Wall Sleeve Installation

The Wall Sleeve installs in the exterior wall framing. Please refer to the Dimensions listed above.

Wall Sleeve Installation

1. Install the wall sleeve into the opening (see above rough-in dimensions) 2. The front edge of the wall sleeve should protrude 1/4“ from the finished surface of the outside wall. 3. Align the sleeve with the wall and adjust the 2 ea. wall sleeve legs, so the bottom pan is angled 1/2

bubble toward the outside of the building. 4. Fasten the sleeve to the wall studs in 3 locations on each side. See drawing above for approximate

locations for fastening. Note: It is recommended that fasteners with seal washers are used, to minimize the possibility of water leakage into the wall.

5. Connect 3/4” nipple to the bottom of the wall sleeve, and connect the condensate trap. 6. Place a bead of silicone sealant or other high grade non-hardening sealing compound approved for

exterior use, to seal the gap between the wall sleeve and both the inside and outside wall surfaces. Sealant should also be applied around the heads of the fasteners used to secure the sleeve.

Damage due to water leakage will occur if the primary and secondary drain lines are obstructed or clogged. Therefore, it is necessary to perform periodic maintenance to ensure that drains remain open.

exterior architectural grille. (bolts and washers included with grille) (figure 2) 3. Remove top metal plate on the base of the wall sleeve. (figure 3)

Please remove the top sheet metal plate on the base of the Wall Sleeve. Failure to do so will result in condensate leaking into the interior of the building.

Unit must be installed with an approved wall sleeve and grille, for safe operation. Improper installation could result in property damage, personal injury or death.

13

Unit Installation 1. Ensure that the supply air ductwork is properly sized, and free of debris, prior to connecting to the unit. 2. Remove packaging from the SPV-HP unit. 3. Remove the rear service access panel and inspect the blower to ensure that is turns freely. 4. Pull electrical disconnect and check all electrical connections. 5. Check power supply and confirm that the nameplate voltage, amperage and fuse size is proper for the

application. 6. Place a 18” x 24” x 1” filter (9SPV -24SPV) or 26” x 28” x 1” filter (25SPV -36SPV). 7. Disconnect the Fresh Air Fan Kit, from the terminal block, if not needed. 8. Ensure that the wall sleeve is installed properly, by using a t-square. 9. Install condensate drain (see page 11 for detail). 10. Remove the cardboard guard from the wall sleeve. 11. Attach the Architectural Louver to the Wall Sleeve, from the inside, using supplied bolts. 12. Inspect the rubber seal, installed in the interior of the wall sleeve, to ensure that is properly sealed and

aligned. Use a non-hardening sealer to ensure that there are no gaps between the seal and the wall sleeve.

13. Once the seal is inspected, and any gaps are sealed, lift the unit into the base of the sleeve and slide the unit forward, so that the equipment is completely sealed inside the enclosure.

14. Check that the unit is seated completely on all four sides, against the seals in the wall sleeve. Seal any openings that may still exist.

15. Connect properly sized electrical service to the terminal disconnect block. 16. Install a factory approved wall controller or approved 24V thermostat, according to manufacturer’s

instructions. Please refer to the SPV-HP wall controller specification book for additional information. 17. Install and connect ductwork into the unit discharge plenum area, to ensure that the connection is leak

free. A flexible duct connector may be used to provide an easier installation and removal of the SPV equipment.

18. Reinstall the rear access panel and disconnect after inspecting the field wiring. 19. Apply power to the SPV unit. 20. Perform System Check.

Unit must be installed by a licensed HVAC contractor.

Unit must not be operated during building construction, due to excessive airborne debris. Units should never be operated without an installed air filter.

Multi Manufacturing assumes no responsibility for equipment installed in violation of any code requirements.

Condensate Drain The condensate drain is incorporated into the bottom of the SPV wall sleeve. The bottom of the SPV wall sleeve includes a 3/4” male pipe thread connection, that penetrates from the bottom of the wall sleeve. A 3/4" female pipe thread adapter must be installed in the field, for condensate. The threads must be sealed with pipe dope / pipe sealant, to ensure that there are no condensate leaks. A minimum 2” trap must be installed in the condensate line, to ensure positive drainage. Prior to unit installation, ensure that the drain is unobstructed and leak free.

A factory installed drain line connects the evaporator drain pan to a vertical pipe connection in the SPV wall sleeve base pan. Condensation from the evaporator is delivered from the SPV unit to a catch tray in the wall sleeve, and if carried through the wall sleeve to a condensate riser through a 3/4” fitting.

The secondary overflow prevents condensate overflow into the closet or living area. In the unlikely event that the primary condensate riser becomes clogged, and water fills the catch tray, water is diverted from the tray through the wall sleeve to the exterior of the building.

Condensate Connection Failure to properly seal the condensate connection may cause a water leak, which could ultimately create a hazardous condition due to mold spores.

16

Sequence of Operation Note: Unit is operated by a wired remote wall thermostat or wall controller, which is connected to an electronic control board in the SPV unit. Type of controller: factory standard wired controller, or 24VAC thermostat. Please refer to the SPV-HP Wired Controller manual for additional information. Compressor and Reversing Valve Control

Active Mode Compressor Reversing Valve State Cooling On De-Energized Heat - Heat Pump（Compressor Heat） On Energized Heat Pump Electric Heat On Energized Heat - Electric Heat only Off De-Energized Dehumidification On De-Energized Fan Only Off De-Energized

Cooling Mode Once the ambient temperature rises past the cooling demand setpoint of the thermostat, and if the compressor is not locked out, the cooling cycle begins. The fan is energized 5 seconds prior to the compressor start up. Once the temperature difference (the setpoint temperature of the indoor thermostat) is less than 2.7° F for 3 minutes, the compressor will be turned off; after 30 a second delay, the fan will be turned off. When the temperature difference (the set temperature of the indoor thermostat) is more than 2.7° F, the compressor will be turned on again. Heating Mode Control Operation There are two heating methods: Heat Pump and Electric Auxiliary Heating. Heat Pump With Electric Heat Operation

1. In an initial call for heating, the evaporator blower motor is energized 15 seconds prior to electric heating elements turning on.

2. The electric heating elements will remain energized for 120 seconds. 3. The electric heating elements will turn off and the compressor will turn on, in the heat pump mode. 4. The heat pump will continue to run, until the thermostat setpoint temperature is met. 5. If the setpoint temperature is not met in 30 minutes of heat pump operation, the compressor will turn off

and the electric heating elements will be energized until the thermostat setpoint temperature is met. 6. The SPV-HP heat pump has an alternate logic programmed in the board. If it is necessary on a replacement

project to supply an SPV-HP unit with similar logic to the unit that is being replaced, the alternate program can be initiated by plugging a jumper plug into the T1 molex plug terminal on the 24V interface board, to the left of the LED display. Skymark and First Co units both cease heat pump operation at 40° F, and rely solely on electric heat below 40° F. When the jumper plug is inserted into the T1 molex plug terminal on the 24V interface board, the SPV-HP will cease heat pump operation at 40° F and will heat solely with electric heat below 40° F. The jumper plug must remain plugged into the T1 molex plug terminal in order for this alternate logic to work properly. (See Figure 4, Figure 5 and Figure 6.)
