Electric Heat Kit 3. Safety precautions Before installing the unit, make sure you read all the “Safety precautions”. The “Safety precautions” provide very important points regarding safety. Make sure you follow them. WARNING This symbol denotes what could lead to serious injury or death if you misuse the Electric Heat Kit CAUTION This symbol denotes what could lead to a personal injury or property damage if Electric Heat Kit is misused. WARNING • Ask your technical representative to install the unit.
Electric Heat Kit CAUTION • Do not install in any place exposed to flammable gas leakage. Flammable gases that accumulate around the Electric Heat Kit may cause an explosion. • Do not use in any special environment. Using in any place exposed to oil (including machining oil), steam and sulfuric gas may deteriorate the performance significantly or give damage to the component parts. Do not install in any place at a temperature of more than 104° F or less than 32° F or exposed to direct sunlight.
Electric Heat Kit 4. Installing the Electric Heat Kit 4.1 Read the safety precautions section of the Multi-Position Air Handler before installing the electric heat option. Remove the entire enclosure from the packaging and inspect for any possible damages. The following images in the installation section do not represent all electric heat options. Depending on the model, the number of circuit breakers might vary as well as the size of the enclosure.
Electric Heat Kit PVFY-A·NAMU-E(1) models: The external static pressure cannot exceed 0.60 in. WG for any position installation when an electric heat kit is installed on the Multi-Position air handler. The static pressure setting for any PVFY-A·NAMU models are set to 0.50 in. WG from the factory. If an electric heat kit is installed and the static pressure exceeds 0.50 in. WG, it is extremely important that SWA is set to the “3” position. 0.3 in. WG (75 Pa) 0.5 in. WG (125 Pa) Notes: 0.6 in.
Electric Heat Kit MVZ-A·AA4(7), SVZ-KP-NA and PVA-A·AA4(7) models: The external static pressure cannot exceed 0.60 in WG for any position installation when an electric heat kit is installed on the Multi-Position air handler. The static pressure setting for any MVZ-A·AA4(7), SVZ-KP-NA and PVA-A·AA4(7) models are set to 0.50 in. WG from the factory. If an electric heat kit is installed and the static pressure exceeds 0.50 in. WG, it is extremely important that Mode/ Function 08/108 is set to “3”.
Electric Heat Kit 4.3 Enabling Electric Heat PVFY-A·NAMU-E(1) models: For PVFY-A·NAMU-E models ONLY OFF ON SW 3-2 OFF ON SW 3-4 When installing the Electric Heat Kit on PVFY-A·NAMU-E models, Switch 3-4 on the control board inside the Multi-Position Air Handler must be “ON”. When installing the Electric Heat Kit on PVFY-A·NAMU-E1 models, Switch 3-2 on the control board inside the Multi-Position Air Handler must be “ON”. This activates the electric heat option.
Electric Heat Kit NOTE For PVA-A·AA4(7), MVZ -A·AA4(7) and SVZ-KP-NA models, electric heat lockout is available as a separate accessory. See accessory, ETC-211000-MIT. MVZ-A·AA4(7), SVZ-KP-NA and PVA-A·AA4(7) models: When installing an electric heater kit for PVA-A-AA4 and MVZ-A-AA4, mode “23” needs to be set to “2”. When installing an electric heater kit for PVA-A-AA7, MVZ-A-AA7 and SVZ-KP-NA models, mode “11” needs to be set to “2”. This enables the heater to operate.
Electric Heat Kit 4.4 Operation Mode PVFY-A·NAMU-E, PVA-A·AA4, and MVZ-A·AA4 Models: The operation of the electric heat kit can be set for different modes, Comfort or Energy-Save mode. PVFY-A·NAMU-E models will be set be SW3-4 and SW3-2 according to below. PVA-A·AA4 and MVZ-A·AA4 models will be set by mode 23 and mode 11.
• PVFY-A·NAMU-E1, PVA-A·AA7, MVZ-A·AA7 and SVZ-KP-NA Models: The operation of the electric heat kit is shown in the table below. See the indoor unit service manuals for more information.

Electric Heat Kit 4.5 Attaching the enclosure to the Air Handler 4.5.A. Remove the Front Cover as well as the Heater Section of the Heater Enclosure. The heater section is secured by (5) screws. Use a 5/16” hex socket or Philips for all screws. FRONT COVER HEATER ENCLOSURE HEATER SECTION 4.5.B. Remove the (4) pieces of foam insulation from the outlet flange on the multi-position air handler and cut the remaining foam so there are no obstructions in the outlet opening.
Electric Heat Kit 4.5.C. Locate the rear flange of the supply side of the multi-position air handler. Rear lange of supply side Rear lange of supply side SVZ PVFY/PVA/MVZ 4.5.D. Locate the angled tab that will secure the enclosure to the top of the multi-position air handler. On the bottom of the enclosure toward the back is the tab. Notice the gap between the angled tab and the back of the enclosure. This is extremely important for installation.
Electric Heat Kit 4.5.E. Position the enclosure on top of the Air Handler so that the rear flange is inserted into the gap explained in step 4.5.D. Next, slide the heater enclosure back so that it is flush with the rear of the air handler. The Angled Tab on the Electric Heat Enclosure slides under the air handler’s rear flange on the supply side.
Electric Heat Kit 4.5.G. From the back of the enclosure, install the (2) brackets which are included in the accessory bag. The four screws shown can be loosened on the Heater Enclosure and Air Handler. Slide the brackets on to the loosened screws and retighten the screws.

Power can be provided to the Multi-Position air handler from the electric heat kit by providing power from the two open terminal connections on the circuit breaker.
Electric Heat Kit 4.5.L. For electric heat kits with two circuit breakers, follow the instructions below: Install the foam insulation provided in the electric heater according to the position of the circuit breakers. For Vertical, horizontal right and downflow positions, install the foam insulation piece shown below in the first image. For Horizontal left installations, see the second image. For Horizontal left installations, the circuit breaker must be rotated 180°, see section 4.
Electric Heat Kit 4.6 Proper Support in the Horizontal Position for the Multi-Position Air Handler with Electric Heat Kit: For horizontal installations providing proper support to the air handler and electric heat kit enclosure ensures an airtight installation. If improper support is provided under the electric heat enclosure, the weight of the ductwork attached to the electric heat enclosure could cause separation between the electric heat enclosure and the air handler resulting in capacity loss.
Electric Heat Kit 4.7 Rotating circuit breaker orientation for Horizontal Left Installations: For horizontal left installations, the circuit breaker(s) must be rotated 180° for proper switch direction for ON/OFF. 4.7.A. Remove the cover and single point power block (for electric heat models above 10kW) from the two circuit breakers. 4.7.B. Remove the electric heat from the enclosure. 4.7.C. Remove the circuit breaker(s) from the support bracket by pulling the tab in the direction shown.
