3. GENERAL UNIT INFORMATION BLOWER & MOTOR

The unit comes with a blower and motor assembly that is mounted to a blower deck inside the unit cabinet, located above the chassis behind the electrical box. Removal of the blower/motor assembly is done through the

chassis compartment opening.

UNIT NAMEPLATES

The nameplate contains information about the unit including model and serial numbers, electrical data and refrigerant charge information. The cabinet nameplate is located on the surface of the cabinet and the chassis

nameplate is located on the chassis. Collecting the in-

formation on the nameplate will be useful when contacting your local customer service representative or when ordering parts. The compressor nameplate is located inside the chassis enclosure (requires removal of sheet

metal enclosure) on the compressor shell.

CONTROLS

The unit comes with a factory supplied transformer. See wiring diagram for field wiring a thermostat to the electrical box low voltage terminals. High voltage connection is made on the left side of the cabinet and low voltage con-

nections enter through the right side of the cabinet.

MICROPROCESSOR CONTROLLER

Unit comes with an advanced microprocessor controller

that monitors the entire function of the unit. The microprocessor board comes with an integral terminal strip for wiring thermostat cable.

REFRIGERANT CONNECTIONS

Low and high pressure side refrigeration service ports re located inside the compressor enclosure. Slide out chas-

sis and remove sheet metal enclosure to access fittings.

CABINET– SILVER SERIES

The standard Silver series cabinet is a fully factory assembled one piece cabinet. See Figure 1. Use flexible duct connections for connecting cabinet to supply ducts to prevent vibration and noise transmission into occu-

pant space.

CABINET– OPTIONAL GOLD SERIES

The optional Gold series cabinet comes in two sections for enhanced acoustic performance. See Figure 2. The upper section discharge plenum is lined with 1” thick insulation on all inside surfaces. Plenum is secured to cabinet with shipping brackets. Once discharge plenum is fastened to the underside of the concrete slab shipping brackets must be removed. See Figure 4 for comparison of Silver and Gold series cabinets. Factory in-

stalled flexible connection joins the upper and lower sections. “S” and “D” cleats are used to join upper and lower plenums to the metal portion of the flex connection. The

plenum comes with factory pre-punched knockouts on all sides.

RETURN AIR PANEL—ACOUSTIC & PERIMETER

The Acoustic Return Air Panel is insulated with 1/2” thick, acoustic insulation and removable without tools to allow access to the filter and (optional) service disconnect switch. The panel is removed by swinging out and lifting it off the support pegs. The panel should be flush mounted to the drywall after the cabinet and riser installation is complete. See Figures 14 to 17 for more de-

tailed information.

The Perimeter Return Air Panel door is mounted in the drywall opening and fastened to the wall studs. See Fig-

ures 18 to 21 for more detailed information.

Cabinet base height and maximum baseboard height dimensions can be determined by referencing Figures 16 & 20. Use appropriate Figure based on R/A Panel type or-

dered.

THERMOSTAT

Unit comes standard with a factory provided 24 inch

long, 6-wire thermostat cable whip pre-wired to the control board terminal blocks.

4. INSPECTION & STORAGE INSPECTION OF UNIT

Prior to the installation of the unit perform the following

checks:

• Visually inspect the packaging, cabinet and chassis

for signs of shipping damage prior to signing the bill of lading. Check that the units match the sales order by referring to the cabinet and chassis nameplate

information.

• Inspect the riser ends for any sign of damage.

• Verify breaker and power supply meet electrical

nameplate requirements of the unit.

• Check that the nameplate of the units matches the

floor plan layout.

When construction is not complete including concrete core drilling, drywalling, plastering, painting or any work that would contaminate the storage space all necessary precautions are to be taken to prevent the cabinet and chassis from becoming contaminated. Particulate infiltration (i.e. drywall dust) into cabinet and chassis coil could result in equipment damage. Fumes could result in premature corrosion (formicary corrosion) of the chas-

sis air-coil resulting in refrigeration system leaks.

OMEGA-VSHP.F-I OM-1907

www.omega-heatpump.com 6

STORAGE

Both cabinet and chassis units are designed for indoor use only. Care must be taken to protect the unit from environmental damage. Store the chassis in an environment with a temperature above (32oF). To prevent contamination the units should be stored indoors. For out-

door storage ensure:

• Units should be placed in an area that will not be

exposed to moisture damage. Units should be placed on a dry surface and on a raised surface. Do

not stack units.

• Cover the units with a waterproof tarp.

• Failure to keep the units dry could result in the inte-

rior insulation becoming wet and cause the growth

of mold which is known to cause odors and serious

indoor air quality problems and health issues.

• Chassis units must be stored in the upright position

to keep oil in the compressor.

• Riser ends should be capped if being stored on site

to prevent contamination from foreign objects and

debris.

Wet insulation can cause the growth of mould. Any sign of mould growth in the interior insulation should be removed, cabinet interior disin-

fected with anti-microbial cleaner and replaced prior to operating the unit.

Do not store cabinets on their side when chas-

sis units are inside. Chassis units should always be stored and transported in the upright position otherwise damage to chassis may

occur.

The refrigeration system of these units contains POE oil. PVC/CPVC piping is prone to failure when in contact with POE oil. PVC/ CPVC piping should not be used for water supply and return with any heat pump prod

ucts as this may result in failure of the system

and serious property damage.

Do not rest or lean the unit on the risers. Do not use the risers or stub-outs to pick up the unit. Only des-

ignated lift points should be used when moving or

lifting cabinets. Do not drop the risers.

5. CABINET & RISER INSTALLATION

Risers are designed to have slight adjustments for riser system expansion and aligning the

stub-outs in the cabinet opening. When in-

stalling risers, do not let riser stubs bottom out

in the riser swage.

Risers are designed to allow for 1-1/2 inches of

movement due expansion and contraction. If the total calculated riser expansion exceeds ±1

-1/2 inches the field must provide expansion compensators.

Riser stub-outs should be located as centrally

as possible in the cabinet opening. Do not al-

low stub-outs to rest or contact the sheet metal opening.

Do not allow the risers to bottom out when

installing into the swage.

FOR SHIPPED LOOSE RISER SHUT-OFF VALVES

Visually inspect riser stub-outs and shut-off valves for debris or damage.

Follow industry standard soldering practices

when soldering shut-off valves to riser stubouts.

Ensure riser stub-out surface is cleaned of any

residue, soot or oils. Failure to adequately clean soldering surfaces can result in water

leaks, property damage and physical injury.

When soldering shut-off valves to riser stub

outs, adequately protect cabinet, insulation and any other equipment from exposure to

flames and heat.

CABINET INSTALL

1. When cabinets are shipped with risers attached, place cabinets in a horizontal position on the floor (do not rest

cabinet on the risers).

2. If required, install any field or factory supplied riser

extensions to the unit mounted risers.

3. Raise the entire cabinet slowly upright while at the

same time lowering the risers through the floor cut-out

opening. Align the risers to the matching swaged section

of the riser on the floor below.

OMEGA | WATER SOURCE HEAT PUMPS O MEGA -VSHP .F-IOM- 1907

7 www.omega-heatpump.com

4.Swaged sections are approximately 3 inches deep.

Risers should be inserted at a depth of approximately 2 inches into the 3 inch deep swage. Confirm risers penetrate at a minimum of 1 inch into the swage. Do not allow the riser tailpiece to bottom out fully into the 3 inch deep swage. This will allow for floor to floor variations, otherwise riser overlap may not be sufficient on upper floors.

See Figure 6.

5. Align and center riser positions in the pipe chase and

level cabinet as necessary.

6. Secure the cabinet to the floor. Cabinet base comes

with factory mounted neoprene pads.

7. Center the riser stub-outs in the cabinet openings to

allow for riser expansion and prevent contact with cabi-

net sheet metal. Prevent riser stub-outs from contacting sheet metal pass through otherwise damage to stub-

outs may occur, resulting in serious water damage. See

Figures 7 & 8.

8. Secure risers to building structure as per engineering design specifications. Do not allow the risers to be supported by the cabinets. Field supplied riser compensators are required if the temperature range of the system

exceeds the expansion and contraction limit.

9. Using industry accepted soldering and brazing stand-

ards and materials to solder or braze the riser joints.

10. Connect supply ducts and discharge grilles. See

Figure 11.

11. Optional Fresh Outside Air Duct details are shown in

Figures 12 & 13 when connecting to remote ERV.

RISER LOOP Servicing

To enable system flushing, servicing and balancing of supply and return risers the following field supplied com-

ponents are required: shut-off valves, drain tees and

drain valves, and flow measuring devices. Refer to the job site engineering design specifications and building

drawings for more detailed information. Flushing & Cleaning

Once the riser system is complete the riser system must

be flushed, cleaned and chemically treated. Do not connect chassis to the water circulating system when flushing is being conducted to prevent debris and fouling of the water side components of the chassis (i.e. auto bal-

ancing valve, auto shut-off valve, coaxial coil).

Do not flush and clean riser system with chassis units connected. Do not allow the flushing and cleansing solutions to flow in the chassis water coil. Damage to water components may

occur.

Supply and return pipes must be interconnected, at a

minimum in the top and bottom units of each riser, with factory supplied hoses to properly flush system and ensure adequate elimination of foreign material and clean-

ing of riser system.

1. Use only clean water to fill water circulation system. Fill the water circulating system at the municipal water

makeup connection with all air vents opened.

2. After air vents have been sequentially closed and riser system is primed begin water circulation of the system to

purge remaining trapped air bubbles.

3. Shut off the circulating pump and open all the drains

and vents to completely drain the system.

4. The riser system should be cleaned after the initial flush and flushed a second time to adequately rinse the

riser system of cleaning solution.

Chassis installation is permitted once the riser system is thoroughly flushed, cleaned, and commissioned by the

riser treatment company and contractor.

RISER SYSTEM LOOP TEMPERATURE

Correct riser system loop temperature settings are important for optimal unit operation. Temperatures outside of the recommended range will affect overall unit operating performance (capacity and efficiency), long term

reliability and sound performance.

Cooling Season

In cooling mode recommended riser loop temperatures should be maintained between 85oF to 90oF. Higher riser loop temperatures reduce unit cooling capacity and efficiency and increase sound levels. Lower riser loop tem-

peratures will increase unit operating efficiency.

Operation of riser loop temperatures above 110oF EWT is not permitted, and sustained operation above 100oF will reduce cooling capacity and may increase unit sound levels and maintenance costs. If loop temperatures are close to permissible levels, riser loop can experience water temperature spikes above recommended during peak demand loads. Refer to Table 2: Unit Oper-

ation Limits.

Heating Season

In heating mode riser loop temperatures must be maintained within 55oF to 90oF for standard range operation. For Geothermal Range operation the system loop must contain an appropriate glycol mixture where system loop temperatures are low enough that could result in freezing of the water circuit. For low temperature operation units must come with factory Geothermal Range option. Do not operate riser system below 20oF EWT due to

reduced heating capacity and efficiency. See Table 2.

OMEGA-VSHP.F-I OM-1907

www.omega-heatpump.com 8

Operating Limits

Table 2: Unit Operation Limits

Design limits can not be combined. Combining maximum or minimum limits is not allowed. This could exceed the operation and

design limits of the unit.

For example: It is not allowed to combine maximum entering air temperature (EAT) limits with maximum enter-

ing fluid temperature (EFT) limits.

6. CHASSIS INSTALLATION

Do not apply plumbers putty, pipe dope or

sealing tape to NPSM fittings.

Always use a back-up wrench when tightening

hoses or fittings. Damage to copper pipes and solder joints could result in serious equipment

and property damage.

Check hoses and fittings for any visible dam-

age or debris.

INSTALLATION OF FITTINGS AND HOSES

Upon removal of service cover panel check cabinet interior for construction debris and dust. Clean out all dust

and debris. Close riser shut-off valves and disconnect factory hoses

from riser supply or return shut off valves.

Units with NPSM Riser and Chassis Fittings

Connect the supplied hoses to the Male-NPSM riser shut-off valves. Do not apply pipe dope or pipe sealant to NPSM fittings. Always use a back-up wrench. Do not overtighten. See Figure 9: Hose Kit Details.

Units with NPT Riser and Chassis Fittings

Connect the supplied male-male (NPT/ NPSM) couplings to the Female-NPT supply and return riser shut-

off valves. Do not apply pipe dope to the NPSM fittings,

as these are JIC style fittings. Connect the supplied hoses to the riser shut-off valves.

Always use a back-up wrench. Do not overtighten.

CHASSIS INSTALL

1. Remove chassis packaging, leaving cardboard shipping cover on the air coil cover in place. Check chassis nameplate to verify chassis model matches cabinet

model for compatibility.

2. Align chassis with front of the cabinet and tilt chassis

so that the back aligns with the cabinet rails.

3. Slide chassis into cabinet partially. Check to ensure wiring harnesses are not being pinched. Adjust the chassis to ensure it is resting approximately centered in the

rails.

4. Connect the hoses by hand to the chassis supply and

return connections. Hand tighten, then using a back-up

wrench tighten fittings as necessary. Ensure that the hose supply and return connections are not reversed and matched to correct risers. Water IN and water OUT

is stamped on the chassis sheet metal enclosure.

5. If riser loop system has been commissioned and oper-

ational open the riser shut-off valves. Check for any signs of water leaks at all water connection points.

6. Connect the chassis electrical plugs to the quick con-

nect mating plugs in the cabinet electrical box.

7. Slide the chassis into the cabinet. Check to ensure wiring harnesses and hoses are not being pinched. Do

not push against the air coil surface.

8. Ensure hoses are not pressed against unit cabinet.

9. Remove cardboard shipping cover from the air coil.

10. Install the service cover panel and visually check foam gasket around service cover panel perimeter is not

damaged and providing an adequate seal.

8. CONTROLS

MICROPROCESSOR CONTROLLER DIP Switch Settings

Controller DIP switch contains 6 switches for setting up thermostat, Fan, and system settings. Microprocessor DIP settings are factory set. Make changes if warranted

by site conditions. Below are the 6 settings: Table 3: DIP Switch Settings

Heat Pump Thermostat

Set DIP #1 to the “ON” position for Heat Pump Thermostat. Refer to the following table for connecting thermo-

stat to unit terminal blocks: Table 4: Heat Pump Thermostat Connections

Heat/Cool Thermostat

Set DIP #1 set to the “OFF” position for conventional HEAT/COOL Thermostat. Refer to the following wiring table for connecting HEAT/COOL thermostats to unit

terminal blocks: Table 5: Heat/Cool Thermostat Connections

Thermostat Cable

Unit comes with a 24 inch long standard 6-wire thermo-

stat cable. This cable is factory wired to TB1 and TB2 terminal blocks on the controller board. Wire other end

of pigtails to thermostat. A minimum 4-wire thermostat

cable is required for single speed thermostats. A field

supplied 7-wire thermostat cable is required if 3-speed fan control is required from a 3-speed thermostat. See Figure 24: Thermostat Wiring Detail.

Multi Fan Speed Thermostat

If connecting thermostats with 3 speed control at the thermostat, DIP switch #6 (FanMode) should be set to

the “ON” position. This will ignore the position of the unit

mounted fan speed selector switch. Fan speed will be controlled by thermostat. Connect thermostat fan speed control wiring to the G1,G2, and G3 terminals as shown below. Fan speed is determined by the G1,G2, and G3

signals from the thermostat: G1 Signal = LOW fan speed enabled. G2 Signal = MEDIUM fan speed enabled. G3 Signal = HIGH fan speed enabled.

Single Speed Thermostat

If connecting thermostats with single speed control at the thermostat set DIP switch #6 to the “OFF” position,

In this mode thermostat can be connected to any of the

G1,G2, and G3 terminals and a “Run Fan” request from thermostat will energize the fan to a speed determined

by the position of the unit mounted 3-speed fan selector switch:

L = LOW fan speed M = MEDIUM fan speed HI = HIGH fan speed

Fan Control with PSC Motors

Fan speed for units with PSC motors is set using each of

the built-in motor speeds and are selected by either set-

ting the fan speed using the unit mounted fan speed

selector switch or a thermostat with 3-speed fan control

capability. See electrical schematic in Figure 22.

Fan Control with EC Motors (ECM)

Low voltage PULSE WIDTH MODULATED (PWM) signal is utilized to control motor speed between 0 and 100% of full speed. The controller has been programmed to use 3 preprogrammed speeds for Low, Me-

dium and High. See electrical schematic in Figure 23.

Whisper Mode (ECM Only)

Whisper mode runs fan a pre-determined low fan speed

for continuous air circulation. Field wire R1 and G1 with

a jumper wire to enable this feature. See Figure 24:Thermostat Wiring Detail for wiring instructions.

Fan Control with ECM X13 Motors

Omega utilizes the X13 ECM motor for larger sized Heat

Pumps. The X13 ECM motor is a multi-voltage motor,

with 5 low voltage speed taps, utilizing 208VAC for pri-

mary power and 24VAC for speed selection.

SEQUENCE OF OPERATION Call for Heating and Cooling

Demand call for Heating or Cooling are initiated at the

thermostat.

If a HEAT PUMP Thermostat type is used, with DIP #1

set to “ON”, control signal form thermostat to terminal

block sets the following:

“Y” Terminal Closed = call for compressor. “O/B” Terminal Open = Reversing Valve De-Energized

(call for HEATING).

“O/B” Terminal Closed = Reversing Valve Energized

(call for COOLING)

If a 1HEAT/1COOL Thermostat type is used, then DIP #1 should be set to OFF. Control signal form thermostat

to terminal block sets the following:

“Y” Terminal Closed = call for COOLING. “O/B” Terminal Closed = call for HEATING.

Note: If both “Y” and “O” are closed, a call for HEATING

is assumed. When a compressor request is made, the auto shut-off

control valve (COAX Flow valve) will open. The compressor contactor will then be energized so long as none

of the following fault conditions are present:

• High-Pressure Alarm

• Low-Pressure Alarm

• Condensate Over Flow Alarm (Optional)

• Compressor Anti-Short Cycle 7 min. timer has not

expired

• Entering Water Temperature is greater than 115

• Leaving Water Temperature greater than 127

When call for compressor request is terminated, the

auto shut-off control valve (COAX Flow Valve) and the blower fan will remain open for an additional 3 minutes.

Low-Pressure Bypass

During a call for compressor, the low-pressure switch is

bypassed for the first 2 minutes of compressor operation

to prevent nuisance low-pressure start-ups.

Timers and Interlocks

Microprocessor board utilizes a number of timers and

interlocks in the control sequence of the unit.

Anti-Short Cycle Timer

The compressor anti-short cycle timer of 7 minutes

starts every time a call for compressor is terminated to

prevent compressor over cycling.

Fan-On Timer

The Fan-On timer of 3 minutes starts anytime there is a call for fan request.

Fan-Off Timer

The Fan-Off timer of 3 minutes starts anytime a call for

compressor is terminated to ensure fan runs for a period

of 3 minutes after the compressor turns off.

Valve Open Timer

The valve open timer of 1 minutes starts anytime a fan and compressor request are made to develop flow in the

water coil.

Valve Closed Timer

The valve closed timer of 1 minutes starts anytime a call for compressor is terminated to allow for flushing of the

water coil.

Random Wait Time on Unit Power Up

Microprocessor controller uses a random wait time dur-

ing unit start up between 1-30 seconds.

9. TROUBLESHOOTING

Refer to the Table 6: Troubleshooting Guide for identifying common issues and possible resolutions. The microprocessor control board has a number of LED lights for simple identification of common alarms and faults. Refer

to Table 7.

TEST MODE

A Test mode feature can be enabled in order to perform diagnostic testing of the unit. Test mode will bypass all

unit timer delays for 10 minutes.

To enable test mode jumper “DI1” pins on the microprocessor board. The unit will operate in test mode. Remove jumper from DI1 if not already done so to get out of test mode. Failure to remove DI1 jumper will disable important safety controls such as High and Low Pres-

sure switches.

Failure to remove DI1 jumper will disable critical safety controls and may cause equipment

or property damage if left disabled.

10. MAINTENANCE GUIDE

Proper unit maintenance will result in optimal unit performance and prevent potentially costly repairs or property damage. Turn unit disconnect switch to off and turn unit off at circuit breaker/

fuse panel before starting maintenance procedure.

Do not operate unit without filters or during any temporary construction that could clog the air filter

or air coil.

Do not use any cleaning solutions that contain acids

on the air-refrigerant coil or any refrigerant compo-

nents.

30 DAY MAINTENANCE

1. Visually inspect filter monthly for dirt and clogging. Re- place as required with a quality filter.

2. Vacuum dust from unit air grilles and surrounding coil area with soft bristle brush attachment as required.

3. Filters with a rating higher than MERV 11 may reduce

airflow and increase fan power consumption and unit cool-

ing or heating performance.

4. Every month visually inspect unit for any signs of water

leaks, or water damage around floor or surrounding dry-

wall.

3 MONTH MAINTENANCE

1. Inspect condensate drain every 3 months for signs of

stagnant water, microbial growth, and mineral buildup. Clean drain pan with an appropriate cleaning solution as required to prevent condensate hose blockages and mi-

crobial growth.

2. Check valves and hoses for signs of leaks, cracking or deterioration.

6 MONTH MAINTENANCE

1. Check condensate flow to ensure adequate drainage and test for signs of impending blockages.

2. Check that condensate alarm is operating correctly. Alarm

trips whenever water level rises above sensor threshold

and locks unit operation.

3. Visually inspect the air coil for signs of dirt accumulation. Use a mild detergent or coil-cleaning agent. DO NOT use

any cleaning solutions that contain an acid, including acetic acid (vinegar). Damage to the air coil may occur result-

ing in possible refrigerant leaks.

ANNUAL MAINTENANCE

1. Perform an annual maintenance inspection of the fan and

blower motor assembly. All units come with permanently lubricated fan motors. DO NOT oil or lubricate fan motors.

Clean up any dirt or debris that may have accumulated.

2. Visually inspect the electrical box annually for signs of

component damage due to overheating or poor electrical

contact.

3. Completely clean the interior of the cabinet. Vacuum any dust or debris.

REPLACEMENT FILTERS

Disposable 1-inch thick replacement filters, sizes listed below and can be obtained from any HVAC parts supplier.

Pleated filters rated between MERV 8 to MERV 11 are preferable as they will provide optimal filtration. Higher rated filters (MERV 12, 13+) may reduce airflow and affect unit heating and cooling performance. Verify that the unit can produce the de-

sired airflow before installing high efficiency filters.

Acoustic Panel Cabinet Base Height Calculation

BH = Baseboard Height + Finish Floor Height* G = Gap (min 0.5”) between baseboard and panel. B = Cabinet Base Height

(Min 5", increases in 1" increments)

B = BH + G - 1.5”

Note: *Include flooring thickness, underlayment, and any concrete leveling as part of calculation.

Example:

If using a 5" baseboard, with 1” Finished Flooring

height, and 0.5" gap:

B = (5” + 1”) + (0.5”) - 1.5”

B = 5" Therefore a 5” Cabinet Base is required.
