The Merit®14HPX model is designed for use with

HFC-410A refrigerant only. This unit must be installed with

an approved indoor air handler or coil. See the Lennox

14HPX Product Specification bulletin (EHB) for approved

indoor component matchups.

This outdoor unit is designed for use in systems that use the

following refrigerant metering device:

Check thermal expansion valve (CTXV)

IMPORTANT

The Clean Air Act of 1990 bans the intentional venting of

refrigerant (CFCs, HCFCs and HFCs) as of July 1, 1992.

Approved methods of recovery, recycling or reclaiming

must be followed. Fines and/or incarceration may be

levied for noncompliance.

TORQUE REQUIREMENTS

When servicing or repairing heating, ventilating, and air

conditioning components, ensure the fasteners are

appropriately tightened. Table 3 lists torque values for

fasteners.

IMPORTANT

Only use Allen wrenches of sufficient hardness (50Rc -

Rockwell Harness Scale minimum). Fully insert the

wrench into the valve stem recess.

Service valve stems are factory-torqued (from 9 ft-lbs for

small valves, to 25 ft-lbs for large valves) to prevent

refrigerant loss during shipping and handling. Using an

Allen wrench rated at less than 50Rc risks rounding or

breaking off the wrench, or stripping the valve stem

recess.

See the Lennox Service and Application Notes #C-08-1

for further details and information.

IMPORTANT

To prevent stripping of the various caps used, the

appropriately sized wrench should be used and fitted

snugly over the cap before tightening.

When servicing or repairing HVAC components, ensure the

fasteners are appropriately tightened. Table 3 provides

torque values for fasteners.

Table 3. Torque Requirements

Parts Recommended Torque

Service valve cap 8 ft.- lb. 11 NM

Sheet metal screws 16 in.- lb. 2 NM

Machine screws #10 28 in.- lb. 3 NM

Compressor bolts 90 in.- lb. 10 NM

Gauge port seal cap 8 ft.- lb. 11 NM

USING MANIFOLD GAUGE SET

When checking the system charge, only use a manifold

gauge set that features low loss anti-blow back fittings.

Manifold gauge set used with HFC-410A refrigerant

systems must be capable of handling the higher system

operating pressures. The gauges should be rated for use

with pressures of 0 - 800 psig on the high side and a low side

of 30” vacuum to 250 psig with dampened speed to 500 psi.

Gauge hoses must be rated for use at up to 800 psig of

pressure with a 4000 psig burst rating.

OPERATING SERVICE VALVES

The liquid and vapor line service valves are used for

removing refrigerant, flushing, leak testing, evacuating,

checking charge and charging.

Each valve is equipped with a service port which has a

factory-installed valve stem. Figure 3 provides information

on how to access and operating both angle and ball service

valves.
